Missing / dropped / glitched frames on fully maxed MBP on import of ProRes MOV

[Zebbler2]

This was a very persistent bug that is ENRAGING, as it forces me to check EVERY SINGLE FRAME I export.
The issue is that After Effects sometimes imports footage incorrectly, with missing, skipped or glitched frames.  I know it's incorrect, because when I click "reload footage" - the issue goes away (but can pop back up after sometimes). I have now upgraded to absolutely specced Macbook Pro, exported natively from After Effects into a ProRes 422HQ mov, bring it back in - and lo and behold - missing frames that flash black (background) in the middle of playback.  How is this issue not fixed, it's beyond me, as it's been years now.  And let's not get me started on how terrible the audio playback is in AE... that's a whole other unfathomable issue, for a company of this scale to no play back audio properly in a product designed for professionals.
But honestly, this dropped / scrambled frame issue is SOOOO IMPORTANT to fix.
There's no way you should be forcing users to watch every single frame in long videos to ensure they are delivered to a client correctly.  NO WAY.

My specs:
AE 25.3.1 (Build 3)

Apple M4 Max 

64 GB RAM

I assigned 300gb to my disk cache, purged database and cache, reloaded the footage to make the missing frame go away, working on this sequence - and boom! another missing frame less than 10 minutes into my work session.  Reloaded again, frame again fixed itself.  WHYYYYYY

Also, not just black/missing frames, straight glitched frames too like this one

Same problem here with AE 25.4.
I have just posted on another thread and didn't noticed this. Exactly the same issue but with exr sequences.

Is it a particular type of footage that is affected? We are aware of an issue with EXR and RED footage that we are working on fixing. But 25.3.1 fixed a different issue around missing or corrupted frames.

A couple things you could try:

* In the Import preferences, turn off Hardware acceleration on imported footage

* Turn off Multi-frame rendering (Prefs -> Memory & Performance) to avoid AE trying to read frames from multiple threads

As to audio, what's the specific issue you're seeing? 

[Zebbler2]

I'll reply more in detail soon, fyi - it was every type of footage for me, but this one, as I mentioned is ProRes 422HQ Quicktime.
And of course - in my final export there's a flash of black, and now I have to circle back five versions to figure out how I missed it and redo the whole thing 😞 😞 😞

Ok, I am situated, and no longer panic attacking.
Since my initial post, I updated to 25.4.0 - are you saying this might have been fixed in 25.4.1?
This glitchy footage on import bug has been going on for at least two years for me.  Generally I make short stuff, so it's not such a huge time commitment to check every frame, but this week it was a ten minute edit for an important client under tight deadline, so I finally boiled over enough to post something about it.  From my experience - it happened with a variety of codecs and footage, and always "reload footage" would fix the error, BUT new glitchy frames would sometimes appear in other places.  I'll update to 25.4.1 and see if that bug pops back up, and will report back if it does.

As far as audio - it's ALWAYS been bad, the main issue is that even when it's "rendered" (green throughout), it sometimes plays sludgy on the first try, then kind of more normal on the second try, like it learns how to do it.  It used to be much worse, like it wouldn't even line up right to the footage (but would export fine, and I'd have to export to preview it in real time).  But now it's more subtle, like sections sounding more reverby and sludgy, then recovering to normal sounding volume.  I tried messing with all possible sound output and buffer solutions, but nothing helped.  Which is the thing that's odd, sound is soooo much less bandwidth intensive, there really should be some setting I can select to make real time sound playback a preference, without any sludgy / draggy / skippy errors.
Premiere Pro pretty much (from what I remember) never had those same issues, sound always just worked fine, fyi.

Oh, I misread the version number you mentioned, - you said it was 25.3.1 and I thought it was 25.4.1 (which is not out yet)
Yeah, glitched / black frame appearing in imported perfectly fine footage is still a bug in the latest I can install - 25.4.0
