I am having this reoccuring issue with frame holds causing a visual glitch on the screen when watching the exported version of the video. I will try to detail all the sources of visuals and export settings below.
Video: 4k .mp4 file (3840 × 2160 - Codec: Timecode, AAC, H.264 - Color profile: HD (1-1-1))
Adjustment layer (This is the white rectangle that slides out)
Graphic layer (This is the blur behind the rectangle)
Exported AE file (.mov) (1920x1080 - Codec: Timecode, Animation)
It seems like the issue arrises from the .mov file since that is the only time this appears in the entire video.
Preset: High Quality 1080p HD
I have tried many variations of the following settings:
Width: 1,920 Height: 1,080
Width: 3,840 Height: 2,160
Frame Rate: 23.976
Frame Rate: 29.97
Performance: Hardware Encoding
Performance: Software Encoding
Use previews: checked and unchecked
Exporting with Premiere and exporting with Media Encoder
I am at a loss here on what to try next to solve this issue.
Thank you for any help in advance!
I forgot to say what system I am on. This is in Adobe Premiere Pro 2021, latest update version (Apple Silicon). MacBook Pro (M1, 2020) Apple M1 Chip. 8 GB of memory. macOS Big Sur 11.5.2.
8 gigs of RAM is the absolute minimum... but supposedly the M1 chips handle memory differently. I think it's possible to use the intel version of premiere on the M1. Might be worth a shot to see if there problems in the new version...
And you might try the smart-rendering workflow if the problem only appears in the export
I actually also tried the intel version versus the apple silicon version and both gave issues. I tried the smart-rendering workflow to no avail. It removed glitches in some frames from one place and they showed up in another.
so when you render to a high quality format like prores, when you're playing the sequence within premiere, you still see glitches? by any chance are any of your sources from a smartphone or a screen recording? If so, the issue may be caused by a source with a variable frame rate.
use mediainfo to determine whether your source is variable or constant frame rate
if it's variable use handbrake to convert to constant frame rate
and here's a tutorial on how to use handbrake
I actually switched to exporting in a way higher quality format and that removed the glitching! Now I can reexport that export into a smaller file size to get within our 800mb file limit.
Thank you for your help!
Thanks for the detailed post.
Have you considered exporting the After Effects file again? Also, please try clearing media cache in Premiere Pro. Here's how: https://community.adobe.com/t5/premiere-pro-discussions/faq-how-to-clear-your-media-cache-in-30-seco...
Let us know how it goes.
On this latest round I reexported all of the After Effects files and it seemed to help a bit, as in there are less occurances of the glitching frames. However, it still happens which is of course a problem. I have also tried clearing the media cache to no avail. I also tried the smart-rendering workflow and it did glitches in different spots that time.
