Quicktime (mov) to Windows Media Video (wmv)

WME doesn't import Quicktime files directly unless they use a cross platform codec like Cinepak or Indeo (and generally they don't). I've mentioned a couple of workarounds earlier - involving uncompressing the QT file to an uncompressed avi. This requires a large chunk of disk space and an additional step. I've found another method which sounds a little complicated but isn't :). We're going to "frameserve" the file to WME. Don't worry what that means; download Avisynth and install it. Now download this Quicktime Import Filter and copy the dll to the plugins folder where Avisynth is installed. Now create a text file with the following text and save it with a .avs extension. You can download this one if you like. Edit the location of the QTsource file and the file you want to convert:



Now load up WME and start create a convert session but don't worry about the settings. In the sources tab select "Both device and file" from "Source from" as below (a strange quirk in WME means you have to do this - I don't understand why) and select the avs file for the video. Accept the same file for the audio if you have Quicktime v.7 installed but if like me you don't have QT 7 and have QT 6 (you need to have at least this), select the original Quicktime file as the audio source. This is because the current version of QTsource doesn't support audio unless you use QT v.7.



Now select the output file as below:



And then your encoding parameters as below:



And then run the encoder. It takes a little longer than usual but it works fine for me. And once you've done it once it's very easy to do it for another file.
