Forums Adobe After Effects No preview, weird behavior

    Hey all, I’ve been working on this AE project for weeks and out of the blue, AE stopped previewing my timeline…

    I can’t seem to find any button that I might have clicked accidentally. I’ve run Adobe Cleaner, uninstalled and reinstalled AE, deleted media database and cache and tried renaming the project. Still no luck. For some reason AE will not preview frames or other compositions.

    You can see screen capture here since I can’t seem to upload video to a post…

    For some reason, screen cap didn’t record the error message, but I also get,

    “After Effects error: Preview needs 2 or more frames to playback” any time I push spacebar when I clearly have more than 2 frames within the work area.

    Laslty, there’s one specific composition that seems to be screwing everything up. If I delete it, the rest of the comp previews fine… Is it possible that one composition can be corrupted even if that composition only consists of solid layer shapes generated within AE?

    I finally figured out by deselecting the continuously rasterize switch on one particular composition was what was preventing AE from previewing…That’s a neat new bug.

    This would be fine, but my comp is not continuously rasterizing now and looks like crap…

    Still haven’t found a solution to this. Seem like the continuously rasterize switch causes some very weird problems throughout the comp…I can’t figure out if it’s something I’m doing wrong or a bug…

    The switch is called “collapse transformations” when you use it on a composition layer, and it works a bit differently than “continuously rasterize” on a vector layer — which is very confusing, because of course it’s the same switch 🙂

    Enabling that switch actually changes the render order in After Effects, and for a comp layer, it treats every layer within the comp as if they were layers directly in the containing comp.

    There’s a really good article and tutorial on this here:
    https://www.schoolofmotion.com/blog/collapse-transformations-continuously-rasterize-after-effects

    The bottom line, unfortunately, is that one cannot simply click “collapse transformations” and get a sharper version of the precomp. There are a lot of things (effects & masks especially) which will behave and render very differently than you might expect.

    (But none of that should cause Ae to fail to preview or render your frame…)

    Thanks, Walter! I will watch that tutorial. I had no idea that that switch did anything other than continually rasterize, but it has been messing up my renders and compositions heeps…Can’t imagine why on earth AE would make that the same switch…
