Hello everyone
First off, let me say that I really like what you're doing, and I appreciate all the work you guys put into OBS. I think it's an amazing piece of software! I've been streaming PC gameplay with OBS for some time now, and would like to take a step towards console streaming.
Now, I've been trying for some time to get information on a capture card to use for XBox 360 streaming. I have done some research, and read lots of stuff in this forum and on other websites. I've narrowed my list of candidates to the Avermedia Live Gamer HD, their Game Broadcaster HD and the Blackmagic Design Intensity Pro. These are, afaics the only affordable PCI-e capture cards that are actually compatible with OBS. I do not want to use an USB solution, out of personal preference, and for the fact that I can't imagine USB outputting a full hd picture, even when YUV encoded to 12bits, at 30fps. If I did my calculation right, thats not possible :D
My setup is going to be this: HDMI splitter (connected to the capture card and my TV, so I can still play without frame lag), software encoding with OBS on an i7-2600k. Streaming will probably be in 720p, but I'd like to keep my options regarding 1080p, so I'm leaning towards the Avermedia to some degree... Unless the HDMI splitter will allow me to have my console set to 1080p while recording with the BMIP at 1080i, which I doubt, but haven't researched.
I currently have a Live Gamer HD for testing here, and was somewhat shocked by the source image quality I get from my PC monitor, which is 1920x1080. The image looked like I would input analogue VGA to an LCD. During my research, I found out this is due to the YUV color space conversion, which has lower color resolution. I want to have the best possible source image quality for encoding, so, what I'd like to know is this:
1) Are there really any differences between the image quality the mentioned cards deliver as input to OBS? As far as I could figure out, they all do a YUV conversion to 12 bits? Is that true? The information was gathered from various sources, like youtube etc. The manufacturers themselves seem to like to keep this info from the user.
2) Are all cards able to handle the Xbox 360 Reference Levels:Extended setting, or in other words, do they process the full RGB range when converting the image to YUV, or do they just clamp to the 14-240 RGB range? I think I read that the Live Gamer HD is able to handle the full RGB range, but when I switched the settings in the XBox dashboard, there was no visible difference in the stream output.
If anyone has some info on this, sheding some light would be greatly appreciated. If this was already answered I deeply apologize, but I really couldn't find it.
Cheers
