MJPEG — Motion JPEG Video Format
MJPEG (Motion JPEG) is a video format in which each video frame is encoded as an individual JPEG image. Unlike modern codecs (H.264, H.265) that exploit temporal redundancy between frames (inter-frame compression), MJPEG uses only intra-frame compression — every frame is independently compressed.
Where MJPEG Is Used
MJPEG is widely used in IP security cameras, CCTV systems, older digital camcorders (particularly early DV and Canon digital cameras), USB webcams, and legacy video capture cards. Its intra-frame nature makes every frame a clean edit point, which is useful for forensic applications and frame-accurate editing.
Converting MJPEG Files with LetsConvert
LetsConvert converts MJPEG video to H.264 MP4, MKV, AVI, and other formats using FFmpeg. Since MJPEG has no inter-frame dependencies, seeking in the source is always precise. The conversion to H.264 typically reduces file size by 80-90% while maintaining comparable visual quality.
Why Convert from MJPEG?
MJPEG produces very large file sizes because each frame is stored as a full JPEG without any inter-frame compression. A 1-hour MJPEG recording can be 5-10x larger than the same content encoded in H.264.
Common MJPEG Conversion Targets
- MJPEG → MP4: Convert to H.264 MP4 to dramatically reduce file size for storage or sharing.
- MJPEG → MKV: Convert to a flexible open container with H.264 encoding.
- MJPEG → AVI: Convert for legacy application compatibility while keeping MJPEG or switching to DivX.
Frequently Asked Questions: MJPEG Format
Why is my MJPEG video file so large?
MJPEG compresses each frame independently as a JPEG, so there is no compression benefit from frame-to-frame similarity. A 30 fps MJPEG video is essentially 30 JPEG images per second — significantly less efficient than H.264, which can share data across multiple frames.
Can I convert IP camera MJPEG streams to MP4?
Yes. If your IP camera saves recordings as MJPEG AVI or MOV files, LetsConvert can convert them to MP4 for more efficient storage.
