 Support for these features is preserved from original VirtualDub, however it does not fully extend to **caching input driver** which is default driver in the package. You can change priority back to **internal AVI driver** or select it manually when opening a file.
+**How to change input driver:** [see this link](OpenVideo), select different option in "Open using".

 Still, these modes should work while using **caching input driver** with limitations on input format:

Direct stream copy and smart rendering state

Support for these features is preserved from original VirtualDub, however it does not fully extend to caching input driver which is default driver in the package. You can change priority back to internal AVI driver or select it manually when opening a file.

Still, these modes should work while using caching input driver with limitations on input format:

video must be I-frame only (no delta frames) and full index must be present
There is a notice in File Information: "index present, optimal random access".
If it is something else, direct copy will not work.
if there are multiple video segments they all must be of same format
does not work with image sequences
does not work with audio (always decodes as PCM)

Also there is simple tool for fragment extraction available under File->Export->Stream copy.
This can copy both video and audio from single (simple) selection, and save to different container (e.g. mp4) when possible.
