When you need to use videos on older playback devices or in professional editing software, the broad compatibility of the AVI format is crucial. Powered by FFmpeg core technology, this tool losslessly converts modern formats like MP4 and MOV into the standard AVI (Audio Video Interleave) container format, maintaining original image quality and audio track synchronization.
Why is the converted AVI file larger than the original?
As an uncompressed container, AVI files are typically 30%-50% larger than H.264 encoded MP4s. This is completely normal.
Which devices require the AVI format? Early car media players, certain surveillance systems, and professional non-linear editing (NLE) software require the AVI container to support specific encoders.
When converting 4K videos, it is recommended to lower the resolution first. Commercial videos with DRM protection cannot be converted. Please download your converted files promptly within 2 hours of completion.
Professional users can adjust the encoder by modifying URL parameters (e.g., adding ?codec=mjpeg). Typical conversion example: 1080p MP4 (H.264) → AVI (DivX) takes approximately 1/3 of the video's duration.
