QuEnc: input format is not YV12 colorspace?

[Ashwood]

I've been using QuEnc to convert AviSynth files created by FitCd (in order to add blocks of overscan to the file. Well, After trying some things to make the program work for mp4s (an utter failure), I now get the error message saying that input format is not YV12 colorspace. I've already reinstalled both programs, but the error remains. Is there a problem with the avisynth code, and if so, what do I need to do to fix it?

Your avisynth code need to convert the colour space of the input video at an appropriate point in the script. If you are using FitCD you can tick the appropriate button on the lower right corner to add colourspace conversion automatically.

You mean the boxes like YUY2-output? I tried checking each of those boxes, but the same error message keeps coming up when I bring the file to QuEnc. Also, the thumbnail image for my avisynth script files is gone (if that helps)

If your encoder requires YV12 input, then just add ConvertToYV12() to the bottom of the script. It's always a good idea to test out the script in VDub(Mod) before sending it to the encoder. If there's something wrong, then VDubMod might give you an error message that will help pinpoint the problem.

Some filters require certain colourspaces to work, in which case you may have to convert earlier in your script. Virtualdub usually gives you a line number with your error. Use this to find where in the script your conversion is missing.

Only certain AVC profiles support YUY2. So chances are that your mp4 does contain YV12. You just need to configure whatever decoder is being used to output it. Saves a YV12-->YUY2-->YV12 conversion.

Could also check out AVIDemux. Supports mp4 input, can add borders and can use libavcodec for DVD output.

How do I add borders in AviDemux?

[Ashwood]

Never mind, figured that out...
I am at a loss to figure out what I should have in the video box. I can't add borders if I select copy, but there's no .avi option. I can't do anything with the Mpeg4 converted file. Which would be the appropriate video option for burning video DVDs? And does the option in the format box have any impact on the file?

[celtic_druid]

Copy, means exactly that. So you can't use filters, etc. It is like direct streaming in VDub(Mod).

For a DVD you would want DVD or DVD (lavc) for video, FFm AC3 for audio and I guess MPEG PS A+V since it doesn't appear to do elementary streams.

AVIDemux can output avi's, but you don't want that for DVD anyway. So yes the output format does make a difference.
