MJPEG video samples have various applications across industries, including:

Using an MJPEG encoder, we can compress the video sequence into a series of JPEG images, each representing a frame of the video. The resulting MJPEG video sample would have a file size that is significantly smaller than the original uncompressed video.

To create a raw MJPEG stream (not inside a container like AVI/MOV), use the format mjpeg :

Finding a ready-made "sample.mjpeg" file online can be frustrating because most public video repositories (like YouTube or Vimeo) re-encode uploads. Here are the three best methods to obtain a pure MJPEG sample.

For archival purposes, a sample using 4:4:4 will be significantly larger but retains color data perfectly.

compression only. It does not use inter-frame prediction, meaning it cannot "look ahead" or "look back" at other frames to save space.

If you need a sample for testing, several repositories provide various resolutions and frame rates:

ffmpeg -i input_video.mp4 -c:v mjpeg -q:v 2 -an output_sample.mjpeg

Several tools are available for working with MJPEG video samples, including:

Run a bitrate scan:

If extraction fails at frame 150, you have a corrupted sample.
