I make videos for my local BMX track races. I have multiple cameras covering different parts of the track and the video from each camera gets combined into single video for each camera minus breaks, etc. It takes me about 30 minutes to edit the video, but 3 to 4 hours to produce the final MP4. It would be great if there was a command line interface so I could spend an evening doing editing, then make a batch script to render the final videos.

Something like
\...\ACDSeeVideoStudio 4.exe path\to\file.avspx \produce \resolution 1920x1080 \format MP4
