Hey, so I haven't seen any info on this, and RVIO 4.0.7 gave me an error when I tried it. I was wondering if you had any plans for supporting "webm" as a destination video format.
The main reason I ask is for Shotgun integration, they state that its best to upload both MP4's and WEBM's for browser compatibility (check their Transcoding page for reference). We're already using RVIO for generating the MP4's, but it looks like WEBM's are currently only generated by FFmpeg. I'd rather use RVIO for this though, if at all possible.
