I have been having this problem where the video seems fine and then out of nowhere starts glitching/flickering and jumping to random frames without me doing anything. here is how it looks like :-

I am working with a link between premiere and after effects, any help would be greatly appreciated.

Try to purge your cache. GO to Edit > Purge > All Memory an Disk Cache.

If the first step doesn't work, try to convert your video to another format/codec.

All these problems probably arise from being screen captures of game video. Many screen capture apps record in crummy video codecs, and users set them to outlandish and useless frame rates.

Highly-compressed codecs make AE -- Plus PP & Dynamic link -- behave strangely. 60 fps for capture is JUST FINE, you don't get any visibly smoother motion with a higher frame rate. The only reason to do it is to create slo-mo.

If your screen capture app won't let you capture to a good intermediate codec, transcode the clip to one after capture.

This problem also happens on camera footages or even jpg images.

Had a similar issue, where occasional frames seem to jump to a random frame, or the frame is inverted upside down. Just one frame, but can happen on both RAM preview and rendering.

I have found the following work around. Right click on the footage in the timeline and Reveal Layer Source in Project. In the Project window, right click the clip and Reload Footage.

It's bit of pain to be honest, but seems to resolve the issue. Not sure if the problem is caused by video that has been sent to After Effects directly from Premiere using Dynamic Link, but have only seen this problem in recent releases of AE.

But are you editing in Premiere or AE?. Maybe I'm missing something but I don't understand your step 3. Are you sending the clips to Premiere using the Replace with After Effects Composition or you are importing the complete sequence in After Effects?

I am editing in AE by using Replace with After Effects Composition.

I noticed that if I render with my resolution set on anything other than full, it doesn't flicker but the different cuts and edits on the footage don't go through and if I set it back to full all my editing appears but the video flicker.

Could you tell us what was exactly your workflow from Premiere?

1- I import a 40 minute video into my bin

2- Finish choosing what clips I want from it and put them all in my sequence

3- Create a link to edit the clips and add effects and such in after effects

4- after editing for a while here is where the problem occurs in after effects.

The flickering went away but the footage got messed up, I am gonna have to readjust the footage on the timeline, but at least there is no more flickering, Thanks!
