Imported movies corrupt in Ae Project

[jaydude-wb]

When working with imported Cinema4D renders, once in a while, some clips have to be rendered again in Cinema4d. When the 3d render is overwritten while it is imported in Ae (in the currently opened project), Ae panics, and some kind of bans the clip forever.

It is logical that while the clip is overwritten, Ae can't work with it, but in stead of switching it to an offline state, Ae comes up with an error (see screenshots), and even when the file is complete again (render in Cinema4d is finished), it will not import/reload again. The clip is kind of 'dead' It seems to have no video content, while in Finder, it just appears to be fine. In other siuations, it is replaced by color bars, but does not Reload when the 3D render is finished.

Please make Ae be more tolerant in this situation: let it reconsider the file's condition on Reload, or on reopen the project, and in every case where it wants to show the error.

Hi @jaydude-wb,

Thanks for reporting this issue. We'll see if we can reproduce the issue and see why the clip is becoming unreadable to AE. Some info that would help us as we investigate:

1. What format are you rendering out of C4D?
2. What version of macOS are you running?
3. Are you rendering to a local drive or shared storage?

Thanks again for reporting this issue and for any further information you can provide,

Hi John,

Thanks for your reply.

I am rendering to ProRes 4444 / 16 bit including Alpha.

My macOS is 12.6.8 (but this behaviour is popping up for years)

Rendering to local drive.

I think that a good start would be to have Ae to don't panic when a file is not readable temporaibly (for whatever reason), but just let it ignore it / replace it by color bars, or offline status (just like Premiere does).

And then, when reloading / replacing let it, not rely on any cached metadata, but refresh it as if it where imported for the first time. (The clips play fine in Quicktime, and in most cases a copied/renamed clip imports fine)

Sorry for the delayed response. Are you still having the issue?
Feel free to reach out. I am moving this thread from Bugs to Discussions for now.

Thanks,
