How do I convert a DIVX file to MKV?

Upload your DIVX file (often an .avi or .divx container with MPEG-4 Part 2 video) to LetsConvert, select MKV as the output format, and choose whether to remux (fast, lossless) or re-encode to H.264/H.265. For a lossless remux, keep the video codec as 'Copy'; for re-encoding, adjust the CRF and audio bitrate. Click 'Convert' and download the resulting .mkv file with all original tracks preserved.

Why should I convert DIVX to MKV instead of keeping the original file?

DIVX files typically use the outdated AVI container, which lacks support for modern features like embedded subtitles, multiple audio tracks, chapters, and metadata. MKV (Matroska) is an open, flexible container that supports virtually any video/audio codec, including the original DivX/MPEG-4 stream, and is widely compatible with media players, smart TVs, and streaming devices. Converting to MKV improves organization and compatibility without re-encoding if you remux, so the file size stays the same.

Does converting DIVX to MKV with LetsConvert preserve video resolution, frame rate, and audio bitrate?

Yes, when you remux (copy video/audio), the original MPEG-4 video stream is copied bit-for-bit into the MKV container, preserving resolution, frame rate, aspect ratio, and audio bitrate exactly. During re-encoding, LetsConvert uses FFmpeg with the same resolution and frame rate by default; you can optionally adjust CRF (e.g., 18–23 for high quality) and audio bitrate (e.g., 192–320 kbps). Subtitles are converted to SRT/ASS and muxed as separate tracks, and chapter markers are retained. Color metadata (like BT.709) is passed through or set based on your source to avoid shifts.
