avi to avc using megui

[iceborne]

i tried converting a short avi clip to avc format using avc but megui stalls endlessly.
i've got no problems converting a dvd to avc using megui, just this. any suggestions?

[berrinam]

any suggestions?
Yep.
1. Tell us what you tried doing (there are 3 modes of operation in MeGUI, and you didn't say where the endless stall was. Also, how can you be sure it is endless?
2. See if you can open your avi in a media player or in VirtualDubMod.
3. Report back with more information.

1. i wanted to convert an xvid encode in an avi container into avc for testing purposes.
i did so by draggin it to megui, and immediately megui's avisynth creator pops up. i accepted everything on default, saved and loaded it in megui.
I left it to encode on 1 pass overnight, woke up the next morning and megui didn't do anything. the log file still says:
[Starting job job5 at 10:01:33 PM
Job is a video job. encoder commandline:
--bitrate 700 --analyse p8x8,b8x8,i4x4 --sar 1:1 --progress --no-psnr --output "C:\Documents and Settings\Administrator\Desktop\5.mp4" "C:\Documents and Settings\Administrator\Desktop\5.avs"
successfully started encoding]

the mp4 ouput file is still at 0kb.

2.the avi opens up in any media player you throw at it and also virtuadubmod btw.

so what do you think?

1. Make sure you have the newest accessible version of MeGUI, in case this is due to some bug (I'm not aware of any, though)
2. Check that all your programs are configured correctly and MeGUI is pointing to them.
3. See if you can open the Avisynth file (*.avs, generated by the AviSynth creator) with virtualdubmod, and check the colorspace (File->File Information).

If you've done all of that and it still doesn't work, there is something very weird going on. In that case, cut a sample of the avi and upload it.

1. checked, i have the newest version.
2. checked, everything is configured and pointed nto
3. virtualdub describes the avs as having YUV2 colorspace

3. It should be YV12. Add ConvertToYV12 at the end of your *.avs file.

now that's more like it!

maybe megui should have this option "converttoyv12" in its avisynth creator if needed.

thanks a bunch.

There is some discussion about that sort of thing in the MeGUI dev thread.
