Well, that's it really. Until recently I encoded video in VP8, good quality and didn't take forever like VP9. When I try to do this using saved settings I get a message "Cannot start video compression. An invalid parameter was specified. (error code -6)"
I don't think anything changed since I use a saved settings profile. Possibly there was some change in originating video codec but these files are all run through an editor with "partial lossless" settings (splices in edits). Originating codec was dxtory. VLC reports all files as "(Codec: H264 - MPEG-4 AVC (part 10) (avc1))." x265 works but takes forever and the file size is several times larger.
I can't even get an idea of what "error code -6" means (what's the matter, did they use up all the numbers after 0?). I have tried switching around everything. I loaded up VirtualDub2, made no changes other than compressor VP8. A file from February renders without comment. One from March does not. Comparing the two files, they are seemingly formatted identically except the one that works has a pixel format of "yuvj420p (709:FR)" and the new one is "yuv420." Does that mess up VirtualDub2? Something I can do about it?
UPDATE:
Ok, I was testing some later raw files, they all passed. Then the current file passed. So it is something to do with the editor. No variables were selected. Output is to MP4. I don't care that much about the container as long as it's compatible and it works.
Anyway, I have a choice in container, as it turns out. I selected MKV (raw files happen to be MKV too) and suddenly VP8 is working again. No idea what changed.
Anyway, moral of the story is try to isolate the variables in your workflow. I was pretty fortunate that there were almost no variables and I have many files, older and newer to compare results against. This is an irritation to have to add yet another step to the workflow but eh, if it works it works.
There is no apparent reason why the older MP4s ran through VirtualDub2 and new ones will not.

UPDATE: Nothing works. VirtualDub2 says "frame format is incompatible" no matter which compressor I try, except for VP8/9 which says of course that an invalid parameter was selected.

The first file (from February) renders just fine. The second does all this scandalous shit. First observation is all this "encoding settings" stuff. And writing library x264 core etc. Apparently that's the problem. But what of it, I changed NOTHING on the video editor side. I am so confused and frustrated. -
No problem saving vp8 and vp9 in mp4 with VirtualDub2 here. Make sure you are sending YUV 4:2:0 to the encoder.
