strangeness rounded when time-remapping is 512 seconds?

OK, this one is total of disconcerting.

I have a script to configure comps with a stack of layers where each layer is actually a stop on images from the video, each layer has activated the time remapping and then I put the value at time 0 for each layer (and then delete the key of the second). I have been using this technique one way or another for years without any problem. Then today, I noticed some glitchy from a certain point results. I assumed it was a matter of 24 / 25 fps but not, it seems to be a rounding problem when the defined time-remapping is greater than 512 dry.

so my troubleshooting code looks like this (the timeOffset value is 0.04 or 1 frame at 25 fps)

alert("tmap about to set as " +  (i*timeOffset))
tMap.setValueAtTime(0,(i*timeOffset);
alert("tmap value that was actually set" + tMap.valueAtTime(0,true))

then, when trying to put the first alert returns with 512.04 as expected but the second alert is back with 512.039978027344 always 512.04 time.

obviously done Ae internal to come round returns with an entire image number (as shown in the user interface), but here's the weird part, this internal rounding seems to work very well all the way to the point of 512 dry but starts then will knock out, almost as if he went from round() to floor()

i.e.

If I put the 484.04 I actually get get 484.039978027344 that I rang the Bell to show the 00:08:04:01 structure, which is what I want

But if I put 512.04 I get 512.039978027344 Ae rounds down to show the frame 00:08:32:00 instead of 00:08:32:01, not what I want.

very frustrating.

It is certainly a bug right?

  • Motion/opacity (yet) does not when you use the time remapping effect

    OK: Here's my meat. This bug has been around for CS3 and CS4. I was hoping this would be fixed with the arrival of CS5, but apparently it still has not been resolved.

    If you use the time remapping effect in the body, you can not use the other features of keyframing, such as movement or opacity. If you do, the video simply disappears. Rendering will not help either. The only way to get the opacity of the function is to overlay a video black bar on the top of the element (or any other cache of color if you like fantasy) and have the opacity on this clip in reverse work. How to get movement in these clips remapped time to work is still somewhat a mystery to me...

    Has anyone found this tedious, boring/irritating?

    So, when can dear Adobe, we expect a fix for this? If all goes well before CS6.

    Thank you very much.

    Richard

    Yes, it's a real annoying bug.
    Simple around - after work you time-remapping your clips, nest (control-click on the clip and select 'nest'), then you can change the opacity normally.

  • Time-remapping has a keyframe when I put new clip in the timeline:

    Hello

    I use PPCS4. I noticed that no matter what new clip that I bring in the timeline to a keyframe effect time remapping to 100%. Is this normal?

    I would like to see no time remap keyframe by default and there are still 100%. The reason is that I use the Mercalli stable plugin and will not work if the time remapping a key image on it. So I always have to erase it first was can use the plugin. A bit boring.

    Thank you

  • Time remapping problem :(

    Hey guys, I may sound stupid for this but I have a problem when I have the time re - map, for some strange reason when I place a keyframe down, its on a straight line almost dead causing the clip to play horribly slow or choppy, sometimes even a fixed image. Oh and this is a clip of 60 frames per second, if that helps0dbbfdbed7a53fc053dcf6c279d8b5e2.png

    I think you look at the graph of speed rather than the value graph. The speed graph is almost useless in the time-remapping. It is the slope of the curve of value that lets you know what is happening with your video. The value graph represents time. Time-remapping is somewhat difficult to understand because you need to display the time in a whole new way. It's like Einstein said, "time is relative." Try showing a graph of reference and modify the value graph.

    Assuming it's the speed graph I see that video is speed up when it gets to the first keyframe, then play at almost a constant speed between the keyframe 1 and 2, it accelerates quickly and then plays a very slowly, increasing speed and so on. There are also rough places in the graph that indicates speed changes quickly. The problem is that I can't say anything about the speed of the element using this view. Take a look at this example.

    Between points 1 KF and KF 2 video playback at normal speed therefore is from time to time real. KF 2 time starts going backwards because the value line goes to the bottom of the Hill. KF 3, KF 4 times is now in the normal direction and because the slope is the same between 1 KF and KF 2 time works again in the right direction. Here's the catch and the thing that is hard to visualize. Time headed worms in real time up to 06:17 then time runs backwards until we get to 16:11, but the time, or frame number, from video to 16:22 2.5 seconds. We have moved the time of the video to 2.5 seconds after viewing the video at 16:11. Did you follow that. See, it's hard to see on the graph.

    Now between KF 4 and KF 5 the fun really begins. You must work for him to think about the value graph, at the time and the speed as the exchange rate graph not playback speed. As you can see the time begins to increase after KF 4 and then reached a steep speed for a few frames, then time begins to slow down until to KF 5, time stops. The speed graph shows time speed up and then slow down.

    So, how do you solve the problem with your time-remapping? First, change the speed graph. Then press the G button and hold down the Alt/Option key to change the tool pen tool conversion Point (the little V on the side) and click on each of the key frames to remove the Bezier handles that cause spikes in the graph of your values. If you want to do some easing in time standard in the remapping and ease ease on does not work most of the time because they are designed for spatial relationships of no temporal relations. This means that you will need to change the Bezier handles in the speed graph very carefully to achieve the desired effect.

    If you have no Windows CD, you can not do a repair installation.

    If you have no Windows CD, the message from the moderator of the Forum Nicholas_W will not help you either.

    If the disk verification fails, there is no sense to try a repair installation because the file system was obviously some problems that must be fixed first (at least that is what I think).

    Wouldn't you want some ideas that actually work?

    The error:

    STOP: 0 X 00000024 0 X 00190203 0X82F42108, 0XC0000102, 0X00000000

    indicates a problem with your NTFS file system.  You can usually solve this by running chkdsk/r from the XP Recovery Console.

    The question was preceded by a loss of power, aborted reboot or abnormal termination? (This includes the plug pulling, buttons power and removing the battery).

    These can cause corruption in the file system that must be fixed before you do anything else.

    If none of these events occurred (or even if they have not taken place), you must verify the integrity of your file system before anything else (especially "try" things).

    Here's how:

    Boot into the Recovery Console Windows using an XP bootable installation CD.

    If you have no XP bootable media (or aren't sure you have) create a bootable XP Recovery CD of Console and do not forget.

    This is not the same as recovery disks that might have come with the acquisition of the system store.

    You can make a bootable Recovery Console CD by downloading an ISO file and burn it to a CD.

    The ISO bootable image file you need to download is called:

    xp_rec_con. ISO

    Download the ISO from here:

    http://www.mediafire.com/?ueyyzfymmig

    Use a new CD and this simple and free program to burn your ISO file and create your bootable CD:

    http://www.ImgBurn.com/

    When you install ImgBurn, DO NOT install the Ask toolbar.

    Here are some instructions for ImgBurn:

    http://Forum.ImgBurn.com/index.php?showtopic=61

    It would be a good idea to test your bootable CD on a computer running.

    You may need to adjust the computer BIOS settings to use the CD-ROM drive as the first device to boot instead of the hard drive.  These adjustments are made before Windows tries to load.  If you miss it, you will need to restart the system again.

    When you start on the CD, follow the instructions:

    Press any key to boot from CD...

    Installing Windows... going to pronounce.

    Press 'R' to enter the Recovery Console.

    Select the installation that you want to access (usually 1: C:\WINDOWS)

    You may be asked to enter the password (usually empty).

    You should be in the folder C:\WINDOWS.  It's the same as the

    C:\Windows folder that you see in Solution Explorer.

    The Recovery Console allows base as file commands: copy, rename, replace, delete, chkdsk, fixboot, fixmbr, cd, etc.

    For a list of the commands in the Recovery Console, type help at the prompt of commands or read on here XP Recovery Console:

    http://www.Microsoft.com/resources/documentation/Windows/XP/all/proddocs/en-us/recovery_console_cmds.mspx?mfr=true

    A good idea before you start things must first verify the integrity of your file system by using the chkdsk command.

    In the command prompt window, run the chkdsk command on the drive where Windows is installed to try to fix any problems on the afflicted player.

    Running chkdsk is fine, even if he finds no problem.  It won't hurt anything to run it.

    Assuming your boot drive is C, run the following command:

    CHKDSK C: /r

    Let chkdsk finish to correct the problems, he could find.

    It may take a long time for chkdsk complete or they seem to be "stuck".  Be patient.  If the HARD drive led blinks always, chkdsk is something.  Keep an eye on the amount of the percentage to be sure that it is still making progress.  It may even seem to go back sometime.

    You must run chkdsk/r again until it finds no error to correct.

    Remove the CD, and then type "exit" to exit the RC and restart the computer.

    You have not to set the BIOS to boot the disk HARD since the CD won't be.

    A few old machines will not recognize a USB keyboard/mouse until after Windows starts.  Look at the back of your computer and see if you have a PS/2 (round) connector for a keyboard and a mouse.  If you do, then you will need to use a keyboard with a round PS/2 connector or a USB-to-PS/2 adapter and plug the PS/2 connector on the back of your computer so that it recognizes the keyboard until Windows starts on your keyboard.

    The SATA driver applies to your hard drive.  A CD of start-up/installation of Windows XP does not recognize a SATA hard drive.  If you install Windows, you will need to hit F6 at the right time and insert a floppy with the SATA driver on this subject.

  • Can one after effects related Composition keep time remapping?

    I use CS6. I have a clip of 1 second test in the first I want to slow down to half speed. That's what I did:

    1. I chose the clip and replaced with After Effects Composition.
    2. In AE I used time-remapping to slow down the clip. Nothing I have AE can show the real slows the effect - unless I export and made into a new file.
    3. I can import which made recently slowed down file in first to replace the original item, and everything is OK.

    However, I prefer not to have to make and the extra file.

    QUESTION

    Can you my version of first link to AE (where I change the speed of the element), and when I finally exporting first, at this stage, it is rendered?

    If not, the latest version of first with its flow optical (or whatever it's called) has the same functionality and quality and AE time remapping?

    Absolutely, I can confirm that exporting AE bound dynamically Pr CC2015 comp that has Timewarp applied the results in an exported clip that interpolated frames and not simply double frames.

    See you soon,.

  • Reverse the time remapping effect?

    Hi, I have a membership with the time-remapping applied via an expression and a skeleton key slider controlling the speed of reading of percentage.

    Inside of the time remapped composition there is an effect property I want to be done by the time remapping. Is it possible to somehow invert the time remapping effect so that it appears unchanged in the composition of parent?

    I think I'm close, but I still can't understand:

    -Hand Comp, example time: 0:00:14:18

    -Comp time to parents: 0:00:14:20, remapped to time right now (maybe before and after by a few images)

    -Nested Comp expression of effect property:

    var time = counteractTimeDisplacement - (((comp("__Main_Comp__").layer ("FrameDifference") .timeRemap - 1)));

    etcEtcEffectPropertyValue = somethingReferenced.valueAtTime (counteractTimeDisplacement);


    -FrameDifference Composition (simply shows the weft of the difference in time)

    Remapped time: 0:00:01:02 / / added 1 second to allow negative values, when the time remapping effect is less, perhaps that should not be a timeRemap property, but I don't know how to use time on an object. null values

    -Expression of remapping the colors:

    ()comp("Main_Comp").layer ("Parent comp') .timeRemap - time) + 1

    Above doesn't work and seems out of step. I realized the FrameDifference composition is also indirectly done by the time remapping effect because the nested composition can access it and its remapped, so I tried for the composition of FrameDifference :

    -Composition FrameDifference

    -Expression of remapping the colors:

    (comp("Main").layer ("Parent model") .timeRemap .valueAtTime (comp("Main_Comp").layer ("Parent comp') .timeRemap) - .timeRemap comp("Main_Comp").layer ("Parent model")) + 1

    Its still not sync, can someone who understands the remapping / time better than me please help I can't see where im going wrong. Yet once I can't get out of the effect inside the remapped comp and use separately as this will cause other problems.

    Thanks for reading

    You make it too difficult. If you have a layer or element that you do not want be affixed by the time remapping effect then put this element in comp. Another thing is just a waste of time.

    Change the speed of reading over time can be very complicated. The best way to understand what you do is look to the graphics editor. You need a much more complex expression in order to speed up and slow down playback without taking the time reverse. Please see motionipt.com where Dan Ebberts can show you how to make the ramp upward and boat speed reading thing.

  • time remapping only keyframes.

    I know it's possible to control selection of kinship between the comp. so that the blades in a model cursors or wha Ewer in one other comp. but is it possible to time remapping those keyframes.


    lets say I have a lets comp. call comp (1) it has a solid blue, a solid red and a comp (2) containing a layer of setting with 2 sliders.


    in comp (2) I animate the slider that the slider, it starts at 0 we a second goes up to 100 more. slider 2 starts at 0, then up to a 100 while cursor one falls down... or something like that...


    I am now able to choose the cursor to whip one and two for the opacity of the red and solid blue in comp (1).


    Now when I play comp (1) solid red goes from 0 to 100 and then the blue charge to do the same thing.


    Here's the question:


    I hope that when I have the time remapped Comp (2) comp (1) solids would fade and go down faster or slower depending on how I have time remapped comp (2) I comp (1).

    but it backs do not work as I expected. keyframes don't move at all, but are kept synchronized whit timecode regardless of my time-remapping.

    is there a way that I can time remap keyframes...

    hope that makes sense.

    If you change a cam multi session in AE you do not use the software as it was designed. Your model will be a mess, check timing on cuts is extremely painful and difficult, changes will be almost impossible and it will take ten times longer than the cutting project in Premiere Pro. AE is not a Publisher. AE was specifically designed to create Visual effects or motion graphics shots or in some cases, a few sequences that you change in a move in a NLE such as Premiere Pro. 90% of my comps AE are less than 7 seconds, because 90% of my cuts in all the movies I make are less than 7 seconds. If you set up your multi cam project in Premiere Pro Cup Multi Cam can be almost as fast as direct switching. You just need to learn how do.

    If you need to perform processing of your shots in AE and then cut it into Premiere Pro, choose the photos you want to fix first. If they are short, and then use dynamic link to process the shots in AE. If every time a need for treatment or plans are long, depending on the settings that you want to do, a better option is to make a digital intermediate (DI) by using a lossless format (or better yet a 10bits or better DI) and do your treatment in AE, and then change the final output in Premiere Pro. Since it is a music production, you'll also want to do your final mix in Audition to take full advantage of the tools available to improve playback of your music.

    If you really want to use a cursor to cut between the two cameras, then that is easily done by linking the opacity for the two layers for a cursor that you animate from 0 to 100. You simply place 100 - in front of the expression of the second camera. If you have two cameras, you could add a checkbox and an if statement then you should change the box to change between 1 and 3 or camera camera 2 and 3. It would quickly become a complex montage and time consuming, and it's never going to be as fast or as efficient as the editing in Premiere Pro using the multi camera configuration.

    If you really want to try it should look like this for 2 cameras:

    Place your cursor on the opacity layer and name it the cursor something meaningful like 'change Camera.

    Camera layer opacity 1.

    thisComp.layer("Controller").effect ("change Camera")("Slider")

    The opacity of the layer camera 2.

    100 - thisComp.layer("Controller").effect ("change Camera")("Slider")
    It will look like this:
    Who's going to do in AE and give you an overlap perfect between the cameras, but I wouldn't try to make that kind of a tool for editing in AE in the first place.
    EDIT: I forgot to mention that if you do not want a dip in brightness when melted between the cameras, you must set the blending mode to add Alpha. You do not have the problem in Premiere Pro.
  • A clip I made the time-remapping on the shortening.

    Okay, so, I'm still very much a first baby and this is the first time I tried to play with time-remapping. First of all, I'm on a PC using first Pro CC 2014.2.

    Basically what I've done is created a cube rotating '3d '. I want to do with it is to rotate quickly, then slow down so that it is possible to read what is written on it. I got successful and ramp at the speed of the way I had hoped.

    However! The clip is really long (I wanted to make sure that I gave myself enough time to play with because I wanted to speed up a bit), then I tried to shorten the clip... but when I do that, anything after the ramp becomes black. The first second or two before the ramp is always visible and spinning, hit the ramp and blackens. I tried just to drag the ends of the clamp as using the razor tool. The razor tool allows me to snap, but when I delete the excess part it always disappears.

    Here is a screenshot just after using the razor tool.

    And it disappears when I delete the excess part.

    I have a feeling that he might have something to do with the first who need to be able to 'see' what's coming or something, and by removing the excess it is unclear what more can be done. But I wanted to ask and see if there was a way to shorten, if not I'll just throw something above the rest of the clip so that you can not see it always go to go back and continue on my way.

    I just had a quick glance and I don't see what is happening. The easiest option is to export the master as an intermediate file without loss and change. When you make the time remapping effect, I always send to AFX and use the efx superior Timewarp, it has its own quirks but it does a better job.

  • Timewarp / time remapping works not well?

    Hi, I have a problem with speed variation. I got 25 fps made out of 3ds max exr images I want to add variations of speed in AE. The problem I face is that the movie stutters when you use the time remapping effect. Basically, what I was trying to do was made the scene very slow out and so I can climb in AE. I even tried different blending modes (moving pixels).

    Here's what happens when you attempt to add some speed changes (when he slow down the initial speed of sequences)

    1. time remapping causes stuttering.

    2. While timewarp gives strange errors (error blur that looks like) interpolation speed goes like 100 - > 150 - > 100 and error occurs when up to 100

    system:

    Windows 7 64 bit, i7 2600 k, 3, 4 GHz, 16 GB RAM, Geforce GTX 580

    AE CS5.5

    Do not use MAX I can only speculate, but questions usually boil down to the underlying platform. I would probably be there platform like a real train carriage works - a support wheel as the anchor, the other under the constraint of the target. By the construction of a hierarchy, you can even build the entire train and it follows the curvature almost perfectly. You then simply copy & paste the keyframes for the main bodies and understand the moment so they are evenly spaced. Once you have, you could apply a temporal distortion curve to the entire animation and everything should happen almost automatically. At least this is how I would approach it in Cinema 4 d. Without knowing your exact configuration, of course, it is difficult to judge these things. Well, anyway, as a minor, you should consider rendering a speed pass also in MAX and using Twixtor Pro instead of Timewarp. that would solve some of your problems already and you might still change using masks. It's definitely worth watching, if you can afford it...

  • Time remapping

    Yep, F1, RTFM opportunity, following recommended links, the book of Mark, etc. and learned a lot about the time remapping effect. The thing that I learned was when using the graph Editor (which is my preferred method) and I want to keep the time for a few seconds, how can I do it without the rest of the ramp is more stiff and speeding to the top of the video? I tried to increase the length of the model to allow extra time, but not luck. Would appreciate any help on this matter. Thank you.

    PS. Y at - it a keyboard shortcut to add a keyframe to ICT?

    You must have 4 keyframes - KF1 - 2 is a ramp, KF2 - 3 is a wedge and KF3 - 4 is a ramp

    In addition, you will find may be easier to move keyframes for 3-4 and maintain the same chart if you're not in the graphics editor! Return to normal mode and take two last keyframe icons and drag to the right - in this way you can not accidentally go up & down in the graph (which changes of speed).

  • New to Ae, need help with time remapping (tutorial anywhere?)

    I am very very big thing back to Ae (CS4) and I was with Premiere Pro CS4 to edit a video, but I need to speed up, but as many of you may know, when you use time remapping in Pr, the sound isn't sync.  However when you do it in Ae, it does.  Then...

    What I'm trying to do is to let the clip I am going for a bit of editing time, then gradually increase the speed to 250% of the original over six seconds, stay 250% for some time, and then gradually in the course of about six seconds to 100% of the original speed.

    I'm kind of having trouble finding how to use Ae well.  There are a lot of easy to understand tutorials out there for Pr, but I can't really find any good for Ae.

    You use the time remapping effect. In fact, when you enable TR, you will notice that the duration of the layer is not limited to the original boundaries more. You can extend beyond the layer's original point.

    So, what you want to do is to keep the TR keyframe at the point layer zero to a value of zero. Set a keyframe second point 06:00 of the layer, with a value of about 14:00 (if possible, because maybe the original clip has no more of any material). You did it like that because if you show 14 seconds of video in a six-second segment, the playback speed is about 250 percent speed. You can do better than 'roughly', but this would require using the speed graph...

    For the real variable speed to set the first keyframe (that at 0:00) to perform a "easy ease on", so the speed ramps up gradually (what means "mitigation" for any property). Setting speed to 100% can be reached at justwith degree sense, but to familiarize themselves with the speed graph will make much more accurate. I say common sense, because if you have a keyframe of a code value of time from 14:00 to 06:00, then a possible way to get back to 100% is to show four seconds of material in the four seconds left (in condition, once again, that your source material has something to 18:00). As you can see, TR needs abundant "handles" (IE, additional documents in the source layer) to work at its 'best.

  • Time remap value is grayed out.

    First CC

    When I try to time remapp a clip I can add keyframes and can change them on the timeline.

    But why can't use them like other keyframes for the Position and Zoom?

    I can't change the scale, I can't catch them and move them to the video effects tab.

    I can only edit and move them in the Timeline... But I want to just total control... I want to give an exact value... I want to make faster the 838%...i want to make correspond them with the other keyframes...

    Please halp...

    Time-remapping is performed on the timeline.

    Time-remapping doesn't have the same kind of key frames, like the other properties.
