Which Windows video conversion programs can make use of installed codecs?

[BNewland]

The organization I work at frequently received old videos, often from proprietary security or camera systems. Many of them use a variety of proprietary codecs, commonly 32-bit VFW codecs (although DirectShow filters are also a possibility).

I've been trying to find a video conversion program for Windows 10 that can make use of codecs we install. I don't care what it converts the video to, as long as it's a commonly used format, but it needs to be able to use these proprietary codecs we install to decode the video.

Any suggestions? I've been searching and am continuing to search.

vdub2 for VFW
graphstudio for directshow

Indirectly, avisynth for both (AVISource for VFW, DirectShowSource for DirectShow) , and an avisynth script can be "fed" into many conversion programs

I went with VirtualDub2 and added the DirectShow plugin for VirtualDub by Phaeron. Seems to do the trick.

I looked up GraphStudio, way too complicated for our users. With VDub2, they just need to change 3 or 4 settings and save the video.

Thank you.
