Convert H264 to AVI

Verified by Adam B.· reviewed by FE Editorial ·updated Jul 27, 2026
QUICK ANSWER
Is it possible to convert H264 to AVI?
Yes - H264 converts to AVI.

Remux the .h264 file into AVI using a video converter - no re-encoding is needed, so quality is identical to the source and the process is near-instant. The output AVI will have no audio because a raw .h264 stream carries video only. If the output plays at the wrong speed, the stream has no timing info and you need to specify the frame rate manually.

Why convert H264 to AVI?

Some legacy video editors and video management software platforms accept AVI but not raw .h264 elementary streams or MP4 containers. AVI is a practical target only when specific older software requires it; for general playback, MP4 or MKV are better choices.

Quality & what to watch

  • The output AVI will have no audio - a raw .h264 stream is video-only by design; if the CCTV recording had audio, it is in a separate file or requires a different DVR export format.
  • Many older AVI players expect DivX or Xvid video rather than H.264 - if the converted file is refused by a player, target MKV instead.
  • If the output plays at the wrong speed, the raw stream has no timing metadata; set the camera's actual frame rate manually in the converter.

Frequently asked questions

Will there be quality loss converting `.h264` to AVI?
Not if the tool remuxes without re-encoding - the video bytes are copied as-is and picture quality is identical to the source.
Why does my converted AVI play too fast or too slow?
Raw .h264 streams carry no timing metadata; set the frame rate manually in your converter to match the camera's recording rate (commonly 15, 25, or 30 fps).
Why is there no audio in the converted AVI?
A raw .h264 elementary stream carries video data only - there is no audio channel regardless of which tool you use.
