What happens to your file

A fast cut copies the video and sound without re-encoding, so quality is unchanged; it starts at the nearest keyframe, which can be up to a few seconds early. Tick Exact cut to cut on the exact frame (the video is re-encoded as H.264).

Fast cut or exact cut?

• Fast cut copies the original video data without re-encoding, so it finishes in seconds and keeps full quality. It can only start on a keyframe, which may be a second or two before the point you chose.
• Exact cut re-encodes the clip so it starts on the exact frame. It takes longer and the file is re-compressed.
• Phone videos usually have a keyframe every 1–2 seconds; screen recordings and some cameras space them further apart.
• To share a short part of a long video, trim first and then compress the result.
• The trimmed file keeps the original format and resolution unless you choose otherwise.
