Facing Persistent Issues with Video Rendering for a Client Project

Question

Hello everyone,

I hope you're all doing well. I have been posting here occasionally about the challenges I face while working as part of a video editing agency. This time, I am dealing with a particularly frustrating issue with one of my client projects for a company https://allofinsta.com/.

The project involves creating dynamic video ads optimized for social media platforms, but I’m stuck at the rendering phase in After Effects. Every time I render the video (which includes multiple compositions with keyframe animations and some third-party plugins), the output either gets corrupted or has random glitches like flickering frames or desynchronized audio. I've tried different codecs and export settings, but the problem persists.

This issue is delaying the project delivery, and I am running out of ideas to troubleshoot it. Has anyone here faced similar rendering problems or knows what might be causing this? Could it be something with the plugins, or is it related to hardware limitations?

If I get an issue with a "heavy" composition that has glitches, sometimes it's simplest to go back to basics and render out an image sequence. This was you never need render out good frames a second time. Then you can render out any frames with glitches again. If these glitches persist, (and you've done all the usual fixes like clearing cache) at a pinch you can snapshot that frame or even use previous frame twice.

These are suggestions to get you through the issue. The glitch is most likely caused by After Effects, your GPU and 3rd-party plugin clashing. Switching to software-render only can help here. You could also consider rendering out just the 3rd-party elements as ProRes 4444 videos and bringing these back into your composition as footage. This will reduce the render requirements.

De-synced audio is harder to fix. Again, it might be worth rendering out the video without audio then combining the audio after.
