Trim video by cutting out unwanted parts


With OpenShot Video Editor you can cut and trim your recording and save the result into a new video.

However, this is only possible when re-encoding/rendering the video again.


Rendering a video comes with some disadvantages

  1. It takes a lot of time
  2. When rendering a video to mp4 (or other compressed formats), you loose some quality.
    Ideal you always revert to the original recording to make edits.
    Re-editing a edited video (multiple times) degrades the video quality unless it is stored uncompressed.


Default the Stream Studio records in 8Mbps Full HD mp4 video format. When trimming a video we advise to save the result in the same quality.
