On the use of sequence_data newbie question

Hi all

I am writing my first AE plugin effect, porting the existing stand-alone C++ code.

Mine is a time filter that works on the current frame with the neighbors of +-N, and I don't mean to make a port full of code, but rather managed to operate as an effect with the fewest possible changes.

For this, I copy data from frame of PF_EffectWorld objects to the type of image I'm using (I managed to do) and the Bank of consecutive in a circular buffer also images from my own fault. The memory for the buffer to be allocated only once, and raster data must be accessible from the rendering of an image to another; otherwise the rendering would be extremely little profitable.

My question is if I can use the sequence_data field to store this circular buffer. I'm quite confused, read the docs, where sequence_data is related to sequence flattening of persistence, but being new to After Effects I have not understood what has been explained. Can I just use PF_NEW_HANDLE when I get a PF_Cmd_SEQUENCE_SETUP and affect my buffer uncontrolled in the field of the sequence_data? Is it safe to use this field I mean?

Those who were my questions, but if you are already experienced with AE and think what I'm trying to do is fundamentally wrong because it goes against the programming/design guidelines/conventions/whatever of AE please give me any suggestions that you could save. I would be very pleased them.

Thank you all for your time.

so... sequence_data, huh?

first of all, Yes. You can use sequence_data for what you described.

You can allocate and dispose of this memory anytime you want.

different appeals of the sequence data will simply tell you what happens.

Allow me to explain. These are the calls you're going to get:

PF_Cmd_SEQUENCE_SETUP.

you get this call only once, when a new instance is first applied to a layer.

you do not HAVE to allocate memory now, but it is the notification you get to have a new instance.

If you do not allocate the memory now, you can later check whether or not a handle exists and do it whenever you see fit.

How do you check?

If in_data-> sequence_data is NULL, then no memory has been allocated.

PF_Cmd_SEQUENCE_RESETUP.

you get it after the following:

When project loads with an existing instance of your effect,

After copy and paste of your effect.

After you save the project.

now, you can decide if you keep the data as it is, or trash and start from scratch.

PF_Cmd_SEQUENCE_FLATTEN.

preparation for the Save/copy.

you get this call only if you have requested is using PF_OutFlag_SEQUENCE_DATA_NEEDS_FLATTENING.

I think it is of interest to you.

Why? because if in_data-> sequence_data is something, AE records regardless of the handle for the project points.

so if you have allocated 100MB to contian 50 frames in each direction, the project file will save these 100 MB within himself.

on the other hand, if in_data-> sequence_data is NULL, then AE stores nothing.

PF_Cmd_SEQUENCE_SETDOWN.

all the garbage.

this instance is being deleted. (or the project of closing)

so, as you can see, you do not have to allocate / free at any time specific memory (except maybe hollow...).

These calls are all logical times for some operations.

You can allocate memory during installation of chassis or rendering, or when you want.

the things I am concerned, using this method, are not technical. they are logical.

first of all, if you're caching the images inside your effect, are you sure that these images are valid?

Maybe the user has changed these frameworks? You can't really tell.

Another concern is that you will not necessarily acquire these images in the correct order (if it is of any importance to you).

you user might be jumping between two random images, then you will be accumulating non sequential images.

It's may be solvable if keep you track of the timestamp origin these images.

and finally, you don't know what random of washing is completed and made sequential began.

There is an effect that makes this kind of cached image describe you: 'CC wide time FX '.

It creates an echo by registering previously acquired images, instead of rendering each image.

the effect is such a pain to use, it's just not worth it.

When you scrub through the timeline the result is incorrect.

and before rendering, it must look to each instance of the effect and click on 'options' to clear the buffer.

not to mention several computers rendered is off limits, as each machine accumulates a different buffer, because jumps frames.

Consider this:

that plugin was created 14 years ago to when the fastest machine was about P1 166 mhz and 128 MB ram are all over the world.

Nowadays, AE hiding executives, asking if the latest images every time doesn't mean necessarily that they made a new. they are very probably cached.

just a thought.

  • ESXi on the new server? -newbie question

    I intend to replace an old server with a new Dell 2950, and when I look at the version virtualized against the standard version there is a significant price difference that ESXi is free, can anyone tell me if I should really buy a ready virtualization server or just a standard and install the ESXi myself?

    I have used VMware in the past and the desire to try on the new server, I hope replace 7 PC with 1 high-end virtualized server.

    Hope someone can advise.

    Thank you

    Gordon

    Hi Gordon,.

    Personally I buy the server and install ESX (not ESXi) inside. It's just my typical setup. The reason why I prefer currently ESX on 'i' is that ESXi is not a service console and some 3rd party applications will not work because they require a SC.

    Although ESXi is 'free' as a stand-alone product, you have to pay for a license one you put in a cluster of virtual center.

    I prefer the standard ESX just like I know 3rd party apps ESX will work.

    Good, please excuse my ignorance... guys xD

    I just bought two s BlackBerry Curve 8530 from Sprint. I'm pretty tech savvy, but there are some things about this phone, I can just enter in two or three days I got em:

    Deleting photos: Well, then I'm in my media folder, in the images. I selects a photo and press the BlackBerry button and select Delete. Then he said: it is read-only, and when I remove it, the icon is still there. I tried to turn on/off the device, and it's still there. Thought this one myself. I plugged it up to the Desktop Manager and all of a sudden all the photos I had taken appeared. I was also able to delete using the "BlackBerry" button and then "delete". It doesn't give me that read this option.

    Saving images: So, for some reason I can't save more photos. I don't know even how I saved the first 12 photos I have taken... but now it won't save any more. What the hell happened? xD I have a 2GB card in my phone... surely these 12 images didn't fill in this card... Thought this one myself. I plugged it up to the Desktop Manager and all of a sudden all the photos I had taken appeared.

    Buy ringtones: On my old phone LG, I used to buy ringtones RealTone Jukebox... where they had extracted from songs that I could download for a crazyhigh. Where can I buy the real music ringtones for BlackBerry? What I do myself?

    Media moving to my PC?: I went through the music store of Sprint comes with my camera, and two purchased songs. I want to know if I can get these songs out of my BlackBerry smart phone and my PC. Also, if anyone knows what format they are in (if they bought before Sprint music store).

    To buy another memory card: Where the best place to buy one of these mini memory cards? One of my friends like, a 24 a concert... and I currently have a 2 gig (who, I should mention, is more fricken memory I have in the computer I do not write about this time xD) how can I find out if the card is compatible with my camera?

    WTF @ Redlight?: From time to time (we can always do that, I'm not sure), the little red light at the top of my unit starts to blink even if I do not have a weak battery or not new messages. It first happened lastnight when a friend sent me 3 IMs at once. I had to reboot my device and I think that he is stopped. Earlier, it happened again (I had several new messages) and this time whenever my display is on, the light was red only flashes do not. It can always be like this now, but I'm not sure. My camera is in the other room and I'm too lazy to check xD. Why would he do that? How can I get him to stop?

    Turn off the sound of the camera?: My camera makes the shutter of the camera, even when noise silence. Is there a way to stop this?


    Auto keyguard: I have EPIC hand-dial to people purse. In my view, it has a keyboard lock button in the dashboard of BlackBerry (that is the correct term for this?) But I want to get to the place where the keyboard auto-lock after a certain period of time. Is this possible? I saw somewhere about pressing the button mute will lock it... who is the top/center of the unit button?

He got the BlackBerry logo on it... is what he called the BlackBerry button? I know, I know, I'm retarded and could probably flip through the manual to figure it out... but still. I might as well ask now xD

I'd love to move the keyboard lock button here though... is it possible?

    There may be an icon on the home screen of your camera to buy ringtones. Or you can open the browser and go to http://mobile.blackberry.com. There is a link of ringtones that you can click

    It is recommended to buy a microSD card to store your multimedia files, if you run out of memory on your device.


    Depending on what OS is your BlackBerry tells you what size you can buy a microSD card. You can check under Options | Topic (will appear as v4.xx.xxx). Look at the table on the following link to see what size you can get - http://www.blackberry.com/btsc/KB05461


    On the BlackBerry, go to Options | Media Media Card recommended parameters are:


    Media card support: WE

    Encryption mode: NO

    Mass storage support: WE

    Auto enable mass storage Mode when connected: YES


    Mass storage mode allows your BlackBerry to act as an extra drive when it is connected to your PC. It will appear as an extra drive letter in Windows Explorer. So you can just drag/release the multimedia files on your memory card

  • Newbie Question: What should I put in for "Hostname" in the DNS Configuration during install ESXi

    Note: I'm not a professional but rather an amateur trying to test the power of virtualization technology. I understand the IP addresses and how to configure my router, Setup static IP address and build my own computer, but I have some limited knowledge when it comes to the configuration of the servers. All I want to do is use this ESXi server locally in my house to run several operating systems on one physical box. I really don't want to have a server on the internet, I think that Comcast doesn't let me run the servers with dynamic IP package I have. In any case, here's my problem:

    I followed with the installation of the link video tutorial ESXi in the intro email vmware sends you after registering. I'm around the 14:30 mark minute now where we are the management network configuration in the configuration menu of DNS.

    The tutorial guys sets its hostname to something he obviously installation but mine appears as "localhost.hsd1.ca.comcast.net". I do not understand what I do when I set up a host name - and as I said above, I don't want to be put in place a server on the comcast network.

    I think I'm a bit confused and don't know what to put in host name. I tried "localhost" and also "localhost.hsd1.ca.comcast.net" but hen t when I chose "network of test management", I got a message of failure for hostname.

    Sorry if it's a super newbie question, but I will not continue to implement virtual machines or what then if this setting is incorrect. I appreciate your time in reading this / to help me. Thank you.

    UPDATE: Ok, so since I'm impatient, I tried just letting the host name to what it was and continues with tutorial and realized that I could simply type the address static IP address from my ESXi server in my web browser from another computer on my home network to get the VI of the esxi Server client , then I typed just 192.168.1.50 which is that I put it was and it was successful! Is there a reason to set a host name then?

    So, my next question becomes: can I run my windows XP 64 OS at the same time as the ESXi Server? Each are installed on different disks in the same physical box, but this computer is one of my main computers that I work on in windows every day so ideally I would have ESXi running but also be able to use the base operating system. Is this possible or am I just dreaming / confused?

    Your welcome hardnesses, I think you can try to re-insalling ESXi with the hostanme you want, or you can connect to the existing installation with an unsupported option and try the same thing.

  • New on Apple computers - Question on the use of the memory (RAM)

    Hello

    I recently bought a rMBP 13 "with 8 GB of RAM. This is only my third time (I started for the first time last night). Here is a screenshot I took of the memory usage after starting it on for the first time. My question is: is it normal to see that most of the memory is in use, even if I only have Safari (1 inactive tablet on the homepage of Google) and open the activity monitor? I'm afraid that this is rare and not have a lot of wrong answers online.

    Second question, if someone has knowledge: 8 GB of RAM is good enough to run software such as MATLAB, AutoCAD and SolidWorks? Or 16 GB would be better? I still have time to exchange the rMBP.

    ElCapitan is designed to use as much RAM as possible at all times for efficient operation.  She will move to a video buffer, operations of common files, etc. in the RAM and the y keep in case he should run again.  CBS will move embusked operations out of RAM if new operations is displayed.

    As for "enough RAM for your planned tasks", 8 GB might be enough, given the fast read/write of the SSD and the very fast moving data in the SWAP file on the SSD.  But if you have any doubt, you have 14 days to return without any doubt and re - buy a Go 156 system.

  • A few questions about the use of data and Cliq

    I have the cliq, however I chose to not get 3G (so I bought full fare). So I have a few questions about the phone and the use of 3G / 2 G/Edge:

    1 - is possible to disable completely the 2G / 3 G/Edge? I know you can switch between them, but are anyway just tell the phone to stop using them altogether since I'm not subbed to the service?

    2. when the update takes place, I guess we'll have to reconnect motoblur and etc, but if I don't have 3 G will I have motoblur connection problems after the update? Or he keeps the latest wifi settings so that it would connect to wifi to connect. When I first got my phone it was not a problem b/c I had 3G for the first month.

    I hope that makes sense, thanks!

    To stop all the data, I would like to download an application called APNDroid. He cut them all down. When you log on to blur you have 3G or WIFI doe this without getting a timeout error. During the process of setting up your Blur account, you can press the menu button and set up your wifi to work, this will connect you to Blur and your phone will be connected to the blur. If I were you I would be rethinking to do a data plan since you are really losing out on most of your main features of phones. It's your choice, however.

  • Smartphone Newbie question blackBerry - general question on the synchronization of e-mail

    Hello

    I have a general question about the synchronization of e-mail and BlackBerry smart phones.  Y at - it none of the devices that enable E-mail synchronization with Microsoft Exchange 2007 system not requiring BlackBerry Enterprise server?

    Thank you; Sorry if this has been asked before but I was unable to find it in the forums, documentation, etc.  Guess what I found for this kind of environment, you will use a BlackBerry Enterprise solution, but I can't assume.

    Thanks again.

    The short answer is no - BB using a different methodology than the use of WM. BB Push, WM uses (for most) sweater. As a result, the long answer...

    BB uses a server solution - it's called the BlackBerry Internet Service (BIS) and it is hosted by your carrier. As an ENCORE, you create a BIS account, then create configurations for different emails, save your credentials for each e-mail account with necessary configuration items (as an ENCORE) (name of the server, the special ports, etc.). Then, BIS periodically checks your mail servers (about every 15 minutes) for any changes on the server that are required on the BB - only, so it generates traffic to your BB to expel these changes. If there is nothing that need to come to the HH, there is no traffic on the network of the carrier.

    WM, on the other hand, devices use (for the most part - there are exceptions) a technology pull... the device itself asks your e-mail servers for changes that need to come to the HH. This generates more traffic on the network of the carrier that the action of the poll itself generates traffic, even if there is nothing to come to the HH.

    Another distinction is the notion of synchronization - in the vernacular WM, it means that what makes your Inbox to the server mailbox and your lines of mailbox HH of the each other for everything (items old and new)... In the vernacular of BB, what is happening is the reconciliation of the new features and changes. But the old elements aren't coming for BB... only news of the moment of activation.

    Another distinction is just what reconcile to a BB - new, remove, read/unread, saved, etc. Which varies according to the messaging service... see this KB for more information:

    Internal preview of Lightroom image handling is difficult for me.

    Previews are displayed in the library modules map, book, slideshow, print and Web with Adobe RGB

    Previews are shown to develop using Pro Photo RGB. 1:1 previews are used to zoom in with, for example in the development of control and sharpness.

    You can limit the size of the cache of previews, if you prefer.

    Reach:

    Edit > catalog settings > file manipulation

    You can choose to ignore the insights 1:1 for example, after 30 days, or never.

    In Ligtroom the working color spaces have been set by default. But you can choose a different color to export space. For example:

    sRGB for display on the web accessories or email

    AdobeRGB for some printers

    ProPhoto RGB for some equipment top of the range, but only with 16 bit images

    A specific profile for printing
