Lower resolution aggressively
For a 10MB target, use 720p or 480p output. Short clips under 30 seconds can often fit at 720p, while longer clips may need 480p.

What to know before you start
Duration matters most
A 10MB limit means roughly 1-2 minutes at 480p or 15-30 seconds at 720p. Longer videos need much lower resolution or trimming.
Check the output
LessMB shows the final file size after compression. If it is still over 10MB, try lower resolution or a shorter clip.
