Which iPhone video editor gives the best export quality?

CapCut and LumaFusion both export 4K without compression artifacts. For maximum quality, export from your chosen app then run ffmpeg -i input.mp4 -c:v libx264 -crf 18 output-final.mp4 as a final quality pass.

Can I use FFmpeg on iPhone?

Yes — via the FFMpeg app on the App Store or through Shortcuts that call FFmpeg from the Files app. This lets you batch process videos exported from CapCut or InShot with precise CRF control.

When to Use FFmpeg Instead

For batch operations — trimming multiple clips, format conversion, quality control — nothing beats FFmpeg. Export from your iPhone app, transfer to Mac/Linux, then:

Trim multiple clips from one video

ffmpeg -i iPhone-export.mp4 \
  -c copy -ss 00:01:30 -to 00:02:15 clip1.mp4 \
  -c copy -ss 00:05:00 -to 00:06:30 clip2.mp4
