Editing VC1 Video

[mstrong]

I have looked for info on this and found a lot of posts from 2013 and nothing with a answer to my question. I edit video using TMPGenc Smart Render 5. It is a great program but I have run into a snag. It will not edit VC1 video files.

When I ran into this problem with TrueHD (which it also doesn't edit) I simple converted the audio into a lossless FLAC file).

Is there a lossless format I can convert the VC1 video to?

Is there a tool that will allow me to edit VC1 video without losing any quality? TMPGenc Smart Render is a lossless editor that modifies only the frames right before and right after your edit.
