Video editing in real-time, is it possible?

Hey all, first of all thank you for reading this post.

I would like to know if it is possible to apply some effects (especially twixtor, some warp stabilizer, color correction) and see the result (perhaps at lower resolution, resolution 1/2, 1/4), without rendering, but the liquid (to check the image goes accordingly with audio, to see the speed change is control with twixtor, etc...)

I have a laptop that is supposed to be powerful: i7-4800mq, 16 GB of RAM, GTX765M, and (perhaps it s the reason why I Don t see the expected result) a hard drive 7200 RPM (SATA 3 GB/s, with 64 GB SSD mSATA capture)

I use the video recorded mainly a gopro 3 black and first pro cs6, sequelae. 1080, 60 frames per second.

I want to change my computer because I have to do a lot of editing of short videos, a lot of twixtor and can´t waiting for renderize whenever I change something and the bar changes from green/yellow to red.

I would like to know:

-If it is normal, with my computer

-If you intend to buy a computer, instead of asking which component you should buy part of (of course you can), what you think of these two:

option 1:

I7 - 4790 K 4.0 Ghz

MSI GeForce GTX 980 Twin Frozr OC 4 GB GDDR5 V

Motherboard: MSI Z97 Gaming ACK 9

Hard drive:

  • Seagate Barracuda 7200.14 3 TB SATA3 64 MB
  • Samsung 840 Evo series of SSD SATA3 500 GB (250 GB x 2 In raid 0)

Kingston HyperX DDR3 2400 16GB PC3 - 19200 2x8GB CL11 Savage


Price: approximately 2100 euros

option 2:

4790 K I7

2 x GTX760 2 GB of GDDR5 memory

Motherboard: GA-Z97X-SLI

Hard drive:

- 2 x HDD 1 TB 7200 RPM Seagate ST1000DM003

-2 x SSD 120 GB Kingston V300

16GB DDR3 1600 MHz (2x8GB) HyperX blue Fury series HX316C10FK2/16

Price: about 1600 euro

I know that I can use proxyes, but I think proxyes with less resolution gives problems with the stabilizer of warp and with less fps gives problems with twixtor.

Don't you think that I'll be able to do the video editing in real-time with these computers? Thank you very much!

GoPro black 3 is very slow on CS6. Twixtor is poorly threaded and does not support CUDA acceleration.

Re option 1:

  • The 980 is way exaggerated, a 760 is more than enough.
  • 16 GB memory isn't enough, you want 32 GB.
  • Forget the EVO. It's far too slow with the Scriptures. Get a 850 Pro.
  • Get a few more HARD and SSD drive to improve disk i/o.

Re option 2:

  • A single video card is supported under CS6. Go on the other.
  • 16 GB memory isn't enough, you want 32 GB.
  • a single 120 GB SSD for media cache and previews is very low. Better to use 256 GB Samsung 850 Pro.

With GoPro material and even with the improvements suggested (more memory, better disk i/o) that you will still experience slowness, jerks, unstable behaviour, because of the quad core CPU.

    Hello!

    Unfortunately, this feature is only available with the GoPro cameras.

    And Yes, if all cables already existing for these purposes, it would be kind of a pain to take pictures and do not shake the camera accidentally. Maybe, VSCO camera makers will make such feature in some time in the future. This idea is excellent and innovative. Maybe even Apple will listen to users and make their new iOS 10.

    ==================================
    If reducing the graphics hardware acceleration
    improves the issue... it's a strong indication that
    you have a problem with your video driver.

    Might be interesting to try to find the support Web site
    Mfg. of your video card for a Win update
    XP compatible video driver. Or... If your computer
    is a laptop... look for the support site for your computer
    Reference of the manufacturer.

    If you do not know the make and model of your
    Video adapter, see the documentation that
    supplied with the computer.

    Also you can find info on your video by driver
    go to Device Manager: you can launch
    By clicking Device Manager on... Start/run and
    type or copy / paste:
    devmgmt.msc
    And then press ENTER.

    Expand "Graphics cards" and right click
    the name of your graphics... then
    choose... Properties / tab pilot... FYI.

    You should find the make and model of your
    adapter display as well as the version of the driver.

    If the driver on the Web site is no longer
    current than you run...
    Download and install it. In addition, installation
    instructions that should be followed closely
    should be available on the support site.

    Once installed the new video driver... you
    can restore your full acceleration.

    Aslde the... If your editing functions have been
    working properly and suddenly changed... I am
    wondering if one of your Windows updates...
    updated your video driver.  Sometimes the new
    driver is not as functional as the one you have already
    a.

    System restore would have been an easy way
    to correct this, but maybe you could go to the device
    Manager and rolling toward the video driver earlier.

    (FWIW... it would be a good idea to create a system)
    Restore point before making the change)

    You can launch the Device Manager by going
    TO... Start/run and type or copy / paste
    devmgmt.msc
    And then press ENTER.

    * Proceed at your own risk *.

  • Video output for PXI embedded real-time?

    I plan to buy a controller PXI real-time Embedded for security monitoring.

    Is it possible to use the video output of a controller PXI running RTOS to display a LabVIEW RT application messages? According to the literature, it seems that the use of the video output is more possible for Controllers PXI running Windows XP.

    Is there a specific application with LabVIEW RT?

    Thanx.

    H.L.

    Well, it works using the IMAQ RT video Out VI: images are displayed properly via the video output of the RTOS PXI controller running.

  • Is it possible to start remotely apply exectutable on target in real time?

    Hi all

    My apologies if this is an obvious question - I couldn't get an answer using the search terms I could think of - and I'm quite new to programming in real time.

    Is it possible to launch a .exe in real-time without head (or not compiled application on the computer of RT) with the help of a contribution by a distance VI - one .exe running on a portable computer based on Windows for example. I'm currently building an application where my Windows based GUI communicates with the use of machine RT shared variable. However I soon would like to put my code on a colleague who will test the application. I remember that a .exe can be saved in a specific on the RT machine folder such that it will launch at startup. However I prefer to store several .exe on the machine and allow my colleague to choose which launch.

    My first thought is to write an .exe wrapper (which will be autolaunch) who can then launch any other .exe saved on the computer using the wrapper. However, I prefer to launch the .exe directly and one at a time if possible - it seems a more elegant solution.

    Best regards and thanks,

    Dave

    Well, there is certainly a way to do it, but NEITHER does not expose this method.  However, you can programmatically restart an RT target and also you can use the vi FTP rename the "startup.rtexe" file that will autorun on reboot.  Good luck!

  • THUMBNAILS VIDEO DISAPPEARED AFTER THE INSTALLATION OF REAL TIME

    After you have installed the latest version of "Real Time Player" which is an upgrade to 'Real Player of cloud', all the video thumbnails are not visible on a single computer. 'Real time' has been installed on two computers with almost identical Windows 7 Home Premium and processors within minutes of each other.  A computer kept all video thumbnails while the other did not. So far I have uninstalled and reinstalled in real time, uninstalled and reinstalled Real Cloud, but still no thumbnail previews. I also tried the verification of the method 'display only the photos '.  I'm looking for someone who's hands are successful on empirical knowledge for this question. Thank you.

    Stanley,

    Here's a recent update on my original investigation.

    After an upgrade of RealTimes Player RealPlayer Cloud download failed to produce thousands of miniature video generated by RealPlayer cloud, I immediately started looking for answers in this forum of Microsoft.

    I have two new computers HP here on my desk. A computer has received the RealTimes Player download and continued to display thumbnails. This is the second HP computer that the thumbnails are not visible.

    Several answers to this problem repeated the same methods. I tried these methods more than once and still no pictures. Then I took action on your message and another someone from Real.com contact Real.com. The only way to contact Real.com was by email on their website. I sent them an email describing the problem. Now, it's my experience that Real.com has even good tech support for free download of RealPlayer. Their first suggestions were identical to the information I received Microsoft community. Following is a concise list of end to end on how I solved the problem before Real.com phoned for help, which may have included access remotely:

    (1) download the RealTimes Player "new" (that's their latest version of RealPlayer cloud;) I know now I should have stayed with cloud of RealPlayer).

    (2) a computer downloaded without any problems, while the second computer lost all thumbnails.

    (3) I contact Microsoft Community to get answers.

    (4) community Microsoft sends answers, including and meet someone from Real.com.

    (5) none of the above gives a solution.

    (6) I am Real.com e-mail for a few days through their website with no solutions.

    (7) I have uninstall RealTimes Player on both computers.

    (7) I call the HP Technical Support to make a 'system restore' on computers.

    (8) after the "System Restore", I reinstall MSE, and all thumbnails are restored on the computer and three external hard drives. All thumbnails are Windows Media files. None of the hundreds of RealPlayer Cloud files can be opened.

    (9) Real.com offers to call me at one time that I choose, which may include remote access to my computer.

    (10) I answer Real.com Friday that a time to call will be the following Monday.

    (11) the following Monday at the appointed hour, Real.com has not called. I waited 30-40 minutes. While I was waiting, I've been on the Real.com site read comments in the section "RealPlayer/RealPlayerCloud. In a response from Real.com Tech to one of the speakers, they gave to this speaker a link to download RealPlayer Cloud. I took a chance with this link and downloaded RealPlayer Cloud in my computer, not only did the Windows Media thumbnails remain, but I was able to play all audio Real Player and video files, and the "Download this video" button a drop down of RealPlayer has been restored. I turned so my attention on the other computer, clicked on a download link that says Cloud RealPlayer on Real.com Web site, and when the download is complete, it was the new RealTimes Player again, not RealPlayer Cloud. But, all right. All thumbnails are back in this computer while being able to play all Real Player files. Now, a computer has the 'new' RealTimes Player and the other has the original cloud of RealPlayer.

    (12) after all this was over, and two computers were back to normal, the representative of Real.com called (almost two hours late; he was on another call that lasted longer than normal). I explained that while you wait for him to call, I reinstalled Real Player on both computers and everything was back to normal. I mentioned reinstalling RealPlayer cloud on the other computer and it recommended that all was well under way, for whatever. I agree with you.

    (13) since the call of the representative, Real.com has sent me a couple of times and told me they were happy that the problem has been resolved and do not hesitate to contact them for any future problems. I asked for a download link for RealPlayer cloud which they sent a warning that they were not certain if the link has an expiration date, but to contact them for any problems or questions.

    (14) although I have Google Chrome on a single computer, all my audio/video download through RealPlayer Cloud/RealTimes drive is via Internet Explorer, not Google Chrome. I prefer the drop-down menu "Download this video" button at the edge of the screen in Internet Archive rather than the barely visible button at the top to the center of the page in Google Chrome.

    Microsoft 15 community) thanks and Real.com.

    (16) a lesson learned. When everything works fine, why switch?

        

     

  • How to play video / real-time in adobe AE cc of 2015 project

    as my title says, how to play video or Project in time REAL in adobe AE cc 2015?

    Sorry for the bad English

    Are aware of the way in which you preview works in After Effects? If not, go here: all about previews in after effects CC 2015

    And, if you're new to AE, you should start here: starting After Effects

    If you know how to get a glimpse, but he is not reading in real time, it could be due to a bug in El Capitan. However, I don't know if you use Mac or Windows. If you are using Mac OSX 11.11.x, there is a bug in El Capitan. You can work around this bug by hiding your timeline during a preview. The best way to do that is to maximize the composition Panel. I do it by pressing on the "key on my keyboard (which is called the serious button it is located on the same key as the ~ [tilde key])." The keyboard shortcut can be different for you, if you have another keyboard or a different language of After Effects installation.

  • Correspondence of time remapping with ramps for video editing of first CC 2015/output

    I would like to ask experts, which will be the best workflow...

    Location:

    I have the project with 50 + video segments where I have to slow down part of the clip to highlight some details (in my case - CIRC. enduro motorcycle - need to slow down the part where is visible some technical riding etc.).

    I use bulit Premiere Pro CC 2015 in the tools of the keyframe to select two points between where I change the speed for example at 50%. First has nice handles around the keyframes where I can create smooth ramp, so the change in speed is graduated.

    Insofar as simple here s

    But the first will not do the same with audio track associated with each clip. In the audio is for his example of the motorcycle.

    I need to have his original when the video is playing at 100% speed and its different from "lower pitch" when is slowed down and once again normal sound when is 100% video speed on the end.

    So I edited each audio segment to the points of the time remap keyframes, manually set the speed of the middle section and - it s horrible. Video slows gently while it is quite annoying audio changes.

    I need to make the same effect as what we were doing with Ribbon old VCRs in television production - smooth audio ramp corresponding to the video and return to full speed.

    As my knowledge about hearing is close to zero - I would like to ask at the front to start learning - I can do up in the hearing? What I have to do it every time from scratch or can I use existing keys from first images? Anyway how above 'automatic '? What workflow you have advice when I need to do it quite often many of these clips?

    Thank you much for the help.

    P. S. tried to find out, after a while with the help chat online too...

    Most of the discussions and tutorials is very old - there may be some new features in CC 2015 in order to do compare with 2011 toolset or almost. And in many video tutorials only covered - they talk about audio at all. But for audio track that I use, is the audio very good.

    Here is an example of a part of the timeline. I needed this project to do quickly, I decided to stretch the entire audio segments to match the new length of the video. It s not correct but it sounds better then it divides in three parts with a slow speed in the middle. Just to match audio speed changes in the Panel of video editing

    time.JPG

    Not sure about the exchange of workflow with first for this type of effect.

    However the hearing can make the effect of change of speed/not very well using effects/time and Pitch/Pitch Bender. This uses a waveform envelope on with keyframes to vary the height must therefore ideal for your needs. In order to see where on the waveform, you need to place keyframes without doubt the best way is to place markers on audio in first at beginning and end of each ramp. These should be done through when you export audio in Audition where you should be able to match Pitch Bend keyframes to markers.

  • Is it possible to record an animation in real-time in Flash?

    My first simple project with animation (via Flash if possible) will be animated in writing.

    The Situation

    I have a text on a background image. I want scribble on one of the words with a digital pen and write another word beside her, exactly as you would when you come across a suspect word what evidence of reading. You will draw the digital pen on a Cintiq 22HD. This is my first use of Flash, so I don't want to spend hours learning how to animate the writing. Just a simple "Record" at this stage.

    Question 1

    In Flash, can I import an image as background, prepare my pen and somehow save my movements of stylus in real time? IE is there a button Save somewhere in Flash? I don't want to save background as well, just the writing part. When I'm done writing I press Stop.

    I hope you end up with is a real-time animation of exactly what I have done with the pen. I can then take the animation and the place elsewhere if necessary.

    Question 2

    If Flash is unable to record, what other software could have this capability?

    There is no document in flash.

  • How can I make a person in a gesture of real time video as the background moves more quickly?

    So the plan is to make a video that has only one in midle or at a specific position in the video in real time and things or people that surround this person to spend x times faster without coverage or ruin the video by spanning the main character. I've seen a few videos with this in my mind, I think that this is done by placing early in the video, the main character in a place that no one intervenes so that it can be done with diapers multiples and mocha. Is it like that? I would really appreciate the help on this.
