Video trimming

Use Cloudinary's video trimming options to keep a specific part of a video or audio clip. To join assets after trimming, see Video concatenation.

Trimming videos

Trim a video (and discard the rest) by using a combination of the following 3 parameters to specify the section of video to keep after trimming:

• start_offset (so in URLs) specifies the start.
• end_offset (eo in URLs) specifies the end.
• duration (du in URLs) specifies the duration.

Possible values:

• A float representing the time in seconds e.g. 5.44 (5 seconds and 440 milliseconds).
• A string representing the percentage of the video length. This string consists of a number with a p appended e.g. 35p (0p is the first frame and 100p is the last frame). The client libraries also support appending a % instead of a p.

Examples:

1. Trimming the video to the section that starts at 6.5 seconds and ends at 10 seconds:

2. Trimming the video to the section that starts 10 percent into the original video and then lasts a duration of 30 percent (effectively from the 10 percent mark to the 40 percent mark):

Trimming audio

Trim audio files with the same three parameters used for trimming videos, start_offset (so), end_offset (eo), and duration (du), in seconds or as a percentage of the track's length. For example, to keep the section of the docs/franck/audio/piano_low track that starts at 2 seconds and ends at 8 seconds:

To join trimmed audio files together, see Concatenate audio files.
