How to split AVI files quickly (general steps)

1. Open the AVI file in your chosen tool.
2. Switch to direct stream copy / lossless mode if available.
3. Set start and end points (use frame-accurate controls for precision).
4. Export or save the selected segments; use batch mode if splitting multiple files.

Tips for truly lossless splits

• Use tools that support direct stream copy (LosslessCut, Avidemux, VirtualDub).
• If possible, trim on keyframes; otherwise some tools will re-encode surrounding GOPs.
• Check codec compatibility—some splits are lossless only for certain codecs within AVI.
