Keep one continuous section using start and duration, then check the re-encoded MP4 at both cut boundaries.

How to use Trim Video

  1. Choose the source and mark the start and end of one continuous section. This tool cannot remove a middle interval and join the rest.
  2. Enter Start and Duration in seconds. To keep source seconds 12–37, use Start 12 and Duration 25; duration is not the end time.
  3. Download the H.264/AAC MP4. Every trim re-encodes; compare the first and last frames and complete words with the original.
