I've been checking out the trial version of Action, and it's pretty nice; however, do you plan on adding the original/1080p video sizes to the standard MP4 file format (non-Intel quick sync)?
My processor is a Sandy Bridge 2600k (which supports quick sync); however, my motherboard is a Saberooth P67 board -- to my understanding, it's "impossible" to use Quick Sync with P67 motherboards

Recording a full screen game in mp4/720p degrades the image quality. I can use AVI, but would prefer to record straight to MP4 for follow-up editing.
Let me know if you need further details,
