Low latency capture card
-
I had to search right settings too.
And it seems deinterlacing doesnt work.. for the moment I hope. -
I wonder how you Gopro works. I have stayed away from using it for live and not testing actually. Do you go HDMI out and do you get clean frame without any icons? I have HD2 sitting araound that I do not use much, but for live there would be a life for it. -

I did a quick test with my Gopro HD Hero 3 black HDMI out yesterday and it seems to work !To remove icons, I had just to set OSD option to Off. And for the settings, I selected 1080/24p on GoPro and Intensity shuttle.If you can't make it work clean, just tell me and I'll give another try. -
OK! I got the mini(micro) HDMI adapter and was able to hook my idle GoProHD2 to Matrox MXO2. Great quality 1080p PAL 25fps. I have a project requiring closeup lens camera and this is absolutely perfect. Now when new HD3 is about to come out I see HD2s selling for 100EUR. It would be great camera for live capture - latency with MXO2 is about 1/3 of a sec, picture is very good on daylight and not too bad with poor lighting(gets grainy) and as a great bonus you can record what the camera sees while broadcasting live. Powering via USB mini connection works fine. And it is a small camera.

The Hero3 black edition is far more expensive, but really better in low light conditions if you need to use it on stage.

I have a LFG4 installed in my MacPro with 2.8Ghz quadCore Xeon, 20GB Ram and dual ATI Radeon HD5770
I am capturing two NTSC streams at half res from the live IMAG cameras, and compositing them with my video content picture in picture style. I am running at full 30fps but there is still a substantial amount of latency and "lip sync" issues with the audio which runs straight through FOH console. Are there any ways I could optimize my system or Isadora to reduce latency? -
You'll always have more or less latency.
Maybe you could add a delay to your audio to resync audio and video.. !Best

Adding a delay to the audio isn't an option for us. I can accept some latency, but I do need to improve it. What are some parameters that affect latency that I can check out?

Sorry, I don't have clear answer about that.
Try to tweak a right balance between resolution-codec-quality in the live capture settings box...regards

@josua have you got any effects on the video?
