So I think I'll have to convert the file to a different codec before sending it to alley, I think I'll try Foto jpg.
My workflow is:
1. Trim the footage with Quicktime so that it loops seemlessly. (Compressor is not the right tool, it cannot play the selected area and loop)
2. Crop the 1920x1080 in Compressor to 4:3 1440x1080 and convert to Foto JPG
3. Convert with Alley to DXV.
Phew. Would be nice to have a tool that can do it all, and on Windows...

By the way Zoltán - I just saw that you live in Székesfehérvár. I've been there several times as a young person when I was on holiday with my family at the Balaton. Funny to see this town's name in a completely different context several decades later...
