VirtualDub - fixing bad frames with blending and without re-encoding

[spicediver10191]

Using Virtual Dub, I'm trying to fix some bad/garbage frames on several large lossless (Largarith) master AVI files before I encode them to lossy formats.

Maybe I'm imagining things, but I seem to remember there's a way in VirtualDub to mask a frame where you blend, rather than duplicate, the replacement frame. And it's done without re-encoding, ie. in Direct Stream Copy mode.

In other words, you create a replacement frame by somehow blending the 2 good frames from before and after bad frame, rather than just using the "mask frame" feature which inserts a duplicate frame of the previous good frame.

Then you re-save the file in Direct Stream Copy mode

Is this possible?

No. But you can reencode just the parts needing 'fixing' and direct stream the rest. That's if VDub has a filter such as you describe. It sounds more like the AviSynth BadFrames filter to me.

Brilliant. It works. Thanks manono - I wasn't familar with that AVS plugin.

Also try using motion prediction to replace the bad frames. I works well sometimes, not so well at others.
