To echo others I had the grainy image as well. It wasn't terribly distracting just present and noticeable. Might have been my imagination, but it seemed more noticeable on the JP+Matt iso cam.
Only other thing worth mentioning for me was audio level balance. The audio was fantastic, and 1 on 1 conversations were great. However, when there was laughing especially Wheat and Matt were able to drown out Geoff and Adam at times if they were continuing a line. It was very minor and situational but worth mentioning in the nitpicking category.
Others mentioning dice. Watching full screen I had little trouble, only d20 rolls made me strain a little. Maybe over sized dice could help? Or have a super zoom camera on the dice box and display that image onto the table monitor could be possible solutions.
Show was 10/10 for me, was a great baseline for future shows requiring only minor tweaks and evolution if desired. Thanks to everyone involved.
