Compressing 1080p WMV with VirtualDub

I got the newest VirtualDub and the VWM http://fcchandler.home.comcast.net/~fcchandler/Plugins/WMV/index.html and extracted it to the plugins folder, then it loads up the WMV and does to a black screen where it says “Missing Codec”. Nothing in the log file.
I am pretty sure I have WMV codec because I can play the file using WMP.
Answer #1
try AVIdemux in place of Vdub
Answer #2
well, not exactly the answer you seek but you can try avidemux or if you want something simpler try xilisoft.
Answer #3
VirtualDub won’t use Directshow codecs by default so that is probably why it wouldn’t open the file. It can only use Video For Windows (VFW) codecs to open files if you don’t open it via an AVISynth file and Directshowsource to allow opening files using Directshow.
I don’t know whether there are VFW WMV codecs available, if not then your only option is to open it via an AVISynth script such as:
Directshowsource("filename", audio=false)
enter the filename and path and save it as something like encode.avs or moviename.avs and open that via VirtualDub.
That will allow VirtualDub to open the file using Directshow codecs, you will need to encode the audio separately, preferably beforehand and then add the encoded audio to the video encode when you set up the encode.
If you want to resize it the add a command to resize the video such as Spline36Resize or Spline64Resize which are the best quality resizers retaining the most detail and with the fewest artefacts. But they are not the fastest available but for the highest quality they are worth it IMO. You can see all available resizers here>

Then you have a very basic AVISynth script to resize and encode your video. You could see the video and mess around altering the commands to get it to your liking if you get AvsPMod and open the script in it and then press F5.
Directshowsource("filename", audio=false)
Spline64Resize(720,304)
Encode using FastRecompress for the best speed and quality.
I didn’t look at the link you posted originally but have now. For me it does open a wmv file but doesn’t display anything until I enable the ffdshow VFW libacodec decoding of WMV/VC-1. I didn’t follow the instructions exactly, I kept the original plugins folder and did not name one as plugins32/64 like the instructions say. You need both the Wmv plugin to allow opening of the video and ffdshow VFW codecs to display it.
But using AVISynth is the better way, it will be faster and better quality as well because if you intend resizing using VD you have to do it in full processing mode which does colour conversions of the video to RGB24 from the source YV12 and then back again afterwards which lowers quality and is quite slow. Using Fast Recompress avoids the colour space conversions which speeds it up and gives better quality.
