I was thinking about yuv420p but I don't know how you want to encode (and what you plan to do with the resulting file). > It would seem like both my capture card and my logitech support > the same formats, but the logitech 920 also lists h264 (listed below) > - is that why it's allowing it to work? That's completely unrelated but has the advantage that you don't have to encode. > What I don't understand is why I'm able to record either video or audio > from the capture card, but when they're both together it's not happy. How should FFmpeg mux audio and video if one has timestamps starting with 0 and the other with 10000000? You can - easily - let the audio stream start with 0 but the problem is that the result will not play in-sync, see the setps documentation.
