Balance resolution and bitrate
At a 25MB target, 720p with a modest bitrate is usually the sweet spot. For very long clips, drop to 480p to stay within the limit.

Can I compress a video to exactly 25MB?
Exact size depends on length and content. Adjust resolution and bitrate iteratively to approach the 25MB target.
What resolution should I use for 25MB?
720p works for most short clips. For videos longer than a few minutes, 480p helps stay within the limit at watchable quality.
Are videos uploaded?
