Question 1

Will trimming the video upload the file?

Accepted Answer

No. Trimming is done locally in your browser; the video never leaves your device.

Question 2

What's the difference between fast mode and precise mode?

Accepted Answer

Fast mode directly copies the video stream without re-encoding, making it extremely fast and lossless, but it can only cut from keyframes, so the start point may slightly deviate from the setting. Precise mode re-encodes, allowing frame-accurate cuts, but it is slower.

Question 3

Will the video quality decrease after trimming?

Accepted Answer

Fast mode doesn't re-encode, so quality is completely lossless. Precise mode re-encodes with minimal loss; high-quality parameters are used, so the difference is imperceptible to the human eye.

Question 4

Can I cut out a middle segment from the video?

Accepted Answer

This tool is for keeping the clip between start and end times. To remove a middle segment, you can trim out the front and back parts separately, then use 'Video Merge' to concatenate them.
