AVI ReComp: The Complete Guide to Recompressing AVI Files

How to Use AVI ReComp for Cleaner, Smaller Video Files

AVI ReComp is a Windows utility that recompresses AVI files (commonly to XviD) to reduce size, crop/resize, burn subtitles, and make files compatible with standalone players.

Install AVI ReComp (use the bundled components: AviSynth, XviD, VirtualDubMod).
Add source: Click “Add” and select the AVI file(s).
Output: Set destination folder and output filename.
Target size / bitrate: Choose a target file size or set video bitrate. For size-focused compression, enter desired output size—program warns if unrealistic.
Video options:
- Codec: Choose XviD (default) or leave as-is for simple remuxing.
- Resize/Crop: Use Resizing button to change resolution or crop black borders to reduce bitrate needs. Preview to check results.
- Deinterlace: Enable if source is interlaced.
Audio settings: Select codec, bitrate, channels, and sampling rate; lowering bitrate reduces file size.
Subtitles/logos: Use Additions → Subtitles to burn in SRT/IDX or add a logo. Preview to confirm placement.
Queue: Click “Queue” → “Add to queue” to batch multiple files.
Start: Click “Start” to begin processing. Monitor progress; times vary by CPU and settings.
Verify: Play the output to check quality and sync; adjust bitrate/resolution and re-run if needed.

Aim for conservative size reductions (e.g., 20–40%) to avoid heavy artifacts.
Use the preview feature before queuing large jobs.
Lower audio bitrate only if acceptable (e.g., 128 kbps MP3 or 96 kbps for speech-heavy content).
If the target device rejects files, disable XviD features like GMC/QPel or use standard MPEG-4 settings.
For best quality at small sizes, reduce resolution (e.g., 720→480) rather than dramatically lowering bitrate.

For non-AVI sources or modern codecs (H.264/H.265/AV1), use HandBrake or FFmpeg.
If you need lossless conversion or advanced filtering, prefer VirtualDub or FFmpeg workflows.
