    If you're ever in Anchorage, Alaska. I'll buy you a beer. Thank you. Not sure which of your suggestions did the trick (I suspect it was trashing the prefs,) but I'm back on track now. No crashes today so far.

    Haha, glad to hear it! Don't underestimate the GPU driver too, though. Always keep that in mind when you start to have weird issues.

  • 11/27/18--11:40: AE crashing on
  • I am having a problem when I opening an AE file, it will just crash and start showing this message.Capture.PNG


    Let me know what is the solution for this.

    I just tried uninstalling all of the Adobe Suite off of my iMac. I also went into my library folder and deleted the cache and commons folders. I reinstalled Adobe Creative Cloud, After Effects and Premiere Pro CC2019. No luck. The Dynamic link is still broken. Such a bummer. This is the one thing that I sold me on this set of software over the competition. I hope that it gets fixed soon.

    I'm not sure if this can be a lower file size, but when I try and render with transparency, it works, but is like 600mb for a 8 second file, and this is really affecting me and my clients, as now it is taking me at least an hour longer than it should take uploading the video!


    I use Quicktime with Animation, but sometimes I use AVI with Lossless Lagarith Video Codec,

    I am having this issue for a while now: When I want to preview my composition en I cache the frames, the already cached frames reload endlessly.

    It is very frustrating since I can't preview the composition.
    Currently, I am using After Effects cc2019. (I don't know if there's more info needed)



    I hope anyone knows how to fix this, I would really appreciate it!

    Welcome to the world of video production. Large file sizes are normal with visually lossless formats. You can get a little smaller files if you use Cineware (GoPro) compression.


    Also, when you render an alpha channel you get one more channel of information in the file so it is going to be about 1/3 bigger than rendering to the same format without an alpha channel.  There are several size calculators on the internet. Here's a fairly decent one. It's missing a few formats but it will at least give you an idea. Video File Size Calculator (by format)

    The removal of those formats is not all Adobe's fault. Apple has drastically changed Quicktime support for both Mac and Windows. A lot of things have been removed by Apple.

    Every time I try to open After Effects it has the audacity to just not open???? It keeps crashing and I don't know what to do. I've never had this problem with After effects so it's kinda wild. When I first updated it I was able to open it with no problems but it's been a few weeks now and I haven't been able to successfully open it since. If this is happening to anyone else or if anyone knows how to fix it it would be much appreciated.

    Rick but why does the older version AE works ok then? Same computer, same OS but others version AE. I do not see the apple issue then.... But if so I can understands find it also a bit strange coded but converting the movies for a one time a year is a bit to much work. So working with the older AE works for me

    In my quicktime format options there is no gopro cinewave, I only have cineform which is a massive file.

    Yup.  Transparency means big file sizes.  Better get used to 'em!  If you've got a lot of transparent area, the Animation codec file sizes can be comparatively small.

    Thanks both of you! I think from now on, most of the time I will do it like a green screen type of thing xD

  • 11/27/18--13:47: Re: Expressions question
  • I actually took the time to go through that entire tutorial. I would classify it as fair because some of the techniques presented are not very efficient and the explanations do not tell you anything more than what the author did. That said let's take a look at the expression and explain what each part does. This should have been explained much better in the video:


    The first few lines set up a recursive loop to take a look at the distance between the layer containing the expression (index = the layer number). If you have a lot of layers this can really get bogged down because it has to look at every layer in the composition before it starts making calculations every time it moves to a new frame.

    // Number.MAX_VALUE is the largest number you can use

    closest = Number.MAX_VALUE;


    /* Loop over all layers in the composition */

    for (i = 1; i <= thisComp.numLayers; i++)


      // Don't check against yourself

      if (index == i)



    distance is just a measurement of the distance from the current layer to any other layer in the comp.

      distance = length(position, thisComp.layer(i).position);


    a simple if statement that starts a calculation using the Math.min() method to compare two values. The calculation starts when the distance between the layers is less than the Number.MAX_VALUE. Unfortunately, Number.MAX_VALUE just means the largest number available in javascript. Personally, I think it would have been more valuable to give closest a value like width and divided it by 2 so you would have a better understanding of when the color would start to change.

    if (distance < closest)

        closest = distance;



    value = Math.min(100, closest / 5);


    I probably would have used a linear method of animating the value based on the distance between the layers. The same general loop would have been used to step through all of the layers but I would have used something like value(t, tMin, tMax, Value1, Value2) to calculate the color change. Value1 would be zero because that is the value for Red, Value 2 would be 120 if you wanted true green, tMin would be the distance between the layers where you wanted the color change to start and tMax would be zero so the maximum color change would be when the layers were lined up. Closest would defined like this:

    closest = width;


    The last lines would look like this:


    t = closest;

    value = linear(t, distance, 0, 0, 120)


    If you want that kind of argument to control scale then you'll need to add an array so the last line of the expression because Scale is an array. That's simple. It looks like this:

    t = closest;

    value = linear(t, distance, 0, 0, 120)

    [value, value]

    I hope this helps.

    Make sure that you dont have extra keyframes form the mask. Sometimes it is hard to see unless you zoom in quite a bit. Sometimes the keyframe is way off in the distance too. If your mask is moving, there is a keyframe somewhere. If you cannot find it, you might unclick the stopwatch to remove all keyframes and reset it.


    - Let me know how it goes.

    The older version still works because it is a version that supported those formats. The formats were dropped because Apple is no longer supporting them, they can be really buggy with the newer versions of Quicktime, they can be hard to decode, and no more work is being done on the formats. A great example is rendering H.264 in a QuickTime container. This was always buggy, didn't do that great a job, and took longer than rendering a properly quantized and compressed h.264 MP4 file with something like the AME. It's not that QT can't playback an MP4, it is that rendering or compressing H.264 in Quicktime was buggy, there were other better solutions out there, so Apple and Adobe both decided it was not worth their time to keep throwing dollars at a technology that was outdated.


    That's how the development of video codecs work. I worked on the development team for RealPlayer in 1995 and 1996, then again in 1998,99. Everybody thought it was going to be the end-all solution for streaming audio, then video. It evolved and nobody uses it anymore. MPEG compression has radically changed over the last few years. H.264 is now the standard for video streaming on video devices. It would not surprise me at all if h.265 or some other technology replaces it in a year or two and the major streaming providers and mobile app developers completely drop their support for h.264.

    Finalllyyyyyy it works in After Effect CC2019 (16.0.0).

    Thank you ADOBE

    Cineform... Sorry, just washed my hands and I can't do a thing with them. Cineform is way better than Animation for a bunch of reasons.
