Video Trimmer
This lesson is part of Web Developer Tools · All levels
Summary
The video trimmer cuts the beginning and end of the video so that only the required parts remain. You set the start and end dots on the timeline, and then the tool generates new clips. Fast cutting typically copies streams without re-encoding, whereas precision cutting re-encodes around the cutting point. Trim differs from crop because trim changes duration, not the area of the image.
Key points
- The trim changes the duration by discarding the parts before the starting point and after the end point
- Stream-copy mode (without re-encoding) faster but tied to the nearest keyframe
- The re-encoding gives the piece more precision at the cost of process time
- Always save the original file before cutting so you can repeat it.
- Note the cutting dots so that the sentence or movement does not break in the middle
