Fast or Precise?
| Mode | Quality | Speed | Cut accuracy |
|---|---|---|---|
| Fast | Original, no re-encoding | Seconds | Snaps to the nearest keyframe, can be off by a moment |
| Precise | Re-encoded | Slower | Exactly where you set it |
Why Fast mode can be a little off
Videos store full pictures (keyframes) only every second or two, and the frames in between depend on them. Fast mode copies the video without re-encoding, so the cut has to start at a keyframe. For most clips that is perfect. When the exact frame matters, choose Precise.

Does trimming add a watermark?
No. GlowPress never adds watermarks.
Is my video uploaded?
No. Trimming happens on your device in the browser.
Will I lose quality?
Fast mode keeps the original quality because nothing is re-encoded. Precise mode re-encodes, with very little visible difference.
What formats can I trim?
Most videos your browser can play, such as MP4 and MOV from phones. The result is saved as MP4.
