I have a video that I made at sort of a weird size (720 x 684) is an animation and this size was a rendering presets I figured it would be a good one to go with. Well turns out that's not a standard size on YouTube which is where it needs to look good so I figured I would convert the footage to 480p which I believe is 640 x 480 with square pixels. (My animated video has square pixels also.) so this seems like something that should be fairly straightforward to do but for some reason I cannot figure out how to do it. I still have the project file open in after effects so I could make changes to that original project file as opposed to editing the video that was rendered from the project.
Here is the link to the video that I uploaded for youtube, as you can see the quality is a very bad:
Thank you for your help,
You should use standard square pixel sizes for your projects and render for Youtube using the AME (Adobe Media Encoder) and the Youtube presets.
The quality didn't look that bad to me, but it could be better. Maybe you first looked at it before YouTube had finished the processing.
