Hi All,
I'm using Lagarith Lossless Codec AVIs in an effort to avoid transcoding quality loss when moving video from Avisynth and VirtualDub to Windows Movie Maker for final editing and rendering. The source is 4:3 720x576. The problem is that Movie Maker 6.0 inputs the Lagarith AVIs at square pixel aspect ratio (=5:4 display aspect ratio), so although you get 720x576 4:3 output, the image itself is narrowed with black pillarbars either side. Although this could be cropped and rescaled to 720x576 afterwards, that would involve horizontal resolution loss as well as re-encoding, both of which I'd really prefer to avoid.
As far as I can work out the Lagarith codec neither stores nor reads any aspect ratio information, and neither does the AVI container. What combination of lossless codec and container can be created by VirtualDub and read by Movie Maker 6.0 AND can correctly convey display aspect ratio? Or any other plan to losslessly move video from Avisynth + VirtualDub to Movie Maker with correct aspect ratio for anamorphic video?
Many thanks,
Francois
