Reporting back: I used the same video clip with Beta H and it worked fine. I find the options for saving rather opaque in comparison with other tools: First, I’ve gotten spoiled by tools that give me some idea of the processed file’s size (in MB/GB) before saving. Next, I’d like to control the target bitrate. For instance, a lot of my work is in 1280x720 with a target range of 2.0–2.4 Mbit/s. In Screenflow, for instance, I set the bitrate at 2400 kbits/sec ... see attached screenshot. That target seems to correspond to around “40” with h.264 in your dialog. Finally, how is audio handled? I assume it is passed through in the original format. Thanks.
