Common questions
What is Fast Trim vs. Precise Trim?
Fast Trim uses stream-copying without re-encoding the video. It takes under 2 seconds and maintains 100% original quality, but cuts at the nearest keyframe. Precise Trim re-encodes the clip for frame-exact cuts.
Why is Fast Trim so fast?
Because it doesn't unpack or re-compress the video data — it simply cuts out the selected chunk of video packets directly from the container file.
Will this add a watermark?
No. FileSwift never adds watermarks or restricts downloads.
