alternative to virtualdub....

[phuture01]

Hi. I'm trying to setup an avisynth script to convert .h264 to dvd that will open up in virtualdub But I keep getting "bela.avs does not have a video stream"

I know it's probably simple but I keep banging my head to the wall...also, I'm wondering if I've loaded all required filters and plugins...here it is:

loadplugin("c:\program files (x86)\avisynth 2.5\plugins\dgavcdecode.dll")
loadplugin("c:\program files (x86)\avisynth 2.5\plugins\nicaudio.dll")
loadplugin("c:\program files (x86)\avisynth 2.5\plugins\dgdecode.dll")
#LoadVirtualDubPlugin("c:\program files (x86)\avisynth 2.5\vdubplugins\DShowInputDriver.vdplugin")

This is me again...Is it true that virtualdub only handles RGB or can it work with YUV files also?

[DB83]

I can not help you with the script by why are you using virtualdub to process the script ?

Vdub will output an avi file so you will still have to process that again for dvd.

Why not load the original .h264 video (not the demuxed one) into avstodvd. That program will create a dvd for you. And you can edit the avisynth script within that program as neccessary.

Others may have different suggestions.

VirtualDub can handle YUV input. If you use it for processing it will convert incoming YUV to RGB. I only use VirtualDub to test scripts before rendering with x264 CLI or HcGUI.

"bela.avs does not have a video stream"
.
.
return MixAudio(lrc, blr, 1.0, 0.2929)

Where's the video in that return statement? Maybe that's not it (can't really understand what you're doing or why you're doing it), but if you want audio and video together you need an AudioDub line somewhere.

When I convert these things for DVD I extract the audio, maybe converting it to something DVD compliant, and only add it back in when authoring. I'm assuming it's from a retail Blu-Ray and probably doesn't need any amplifying to begin with. Something like MKV2AC3 can normalize the volume, if necessary.

And as DB83 asked, what are you doing in VDub anyway, if the goal is a DVD? Do you want to open the script and then save out the audio?
