Software for Lossless Capture of HD Video and 5.1 Audio
Posted: Mon May 22, 2017 4:02 pm
I'm trying to capture 720p-1080p60 video + 5.1 audio coming out of a DVR via HDMI. All of the Blackmagic and DeckLink models "support 8 channel HDMI audio". Using an HDMI audio injector, I could insert the 6 channels of 5.1 audio, BUT I cannot find any capture software that will LOSSLESSLY capture the video AND 5.1 sound. When using a Magewell capture card (which also supports 8ch HDMI audio) with OBS or Virtual Dub and lossless codecs, only 2 of the 6 channels are allowed through by the SOFTWARE to be recorded, even though the card itself passes all 6 ch through to the software. Does anyone know of any AV capture software that will losslessly record both HD video AND 5.1 audio from an HDMI input when using Blackmagic or DeckLink capture cards?
