You don't need to learn Adobe Premiere to edit good videos. Here's the minimum you need to know.
The Only 3 Edits That Matter
1. Cut: Remove mistakes, pauses, and dead air. This alone makes 80% of videos better. 2. Audio levels: Music shouldn't drown out speech. Voice at -12dB, music at -25dB. 3. Color correction: Auto-enhance is usually enough. Don't overthink it.
Free Software
DaVinci Resolve (professional, free). CapCut (mobile, easy). iMovie (Mac/iPhone). All three handle basic editing perfectly.
After editing, compress your video for sharing, or optimize for email if you need it under 25MB.
