The most economical option to capture video 4.4 AVerMedia Live Gamer Portable 2 Plus GC513.4.2 Zhongkaifa, HDMI capture with USB C connection.4.1 AVerMedia Live Gamer Mini Capture Card GC311.2 HDMI Video Capture, how does it work?.1 The most economical option to capture video.Unless anyone knows any other cards?Īlso does anyone know if there are any knock off copies of the Magewell Pro Capture, as their usb devices seem to have been well and truly copied. I did notice that, and it seems about the only card (without breaking the bank) that can do both YCbCr 4:4:4 or 4:2:0 chroma sub-sampling. I can't tell you whether the GH3 uses YCbCr 4:4:4 or 4:2:0 chroma sub-sampling for its HDMI output, but if you are still considering a PCI-e card, the specs for the Magewell Pro Capture HDMI say "Support for RGB 4:4:4, YCbCr 4:4:4, YCbCr 4:2:2 color sampling" But do you have any idea what the GH3 outputs? Since the 4:2:0 over HDMI was obviously wrong information, does it output 4:2:2 or 4:4:4? I can't find this information from anywhere. If your source is YCbr 4:4:4, you're forced to make a sub-par capture. Magewell XI100DUSB says it does YUY2 and RGB24, i.e. I have had second thoughts and decided to consider non PCIe options as well - What about USB3 or thunderbolt devices from other companies? Can the Avermedia live gamer extreme or the Magewell XI100DUSB handle capture at 4:2:2 or 4:4:4? If plan to capture at at 4:2:2 or 4:4:4 and not do any other conversion, do you think the intensity pro 4k is good for this? But what sort of file sizes will it equate to per minute at 4:2:2 or 4:4:4. So with this in mind it sounds better to capture at 4:2:2 or 4:4:4 without doing any other conversions. Thanks for this, I did not know that the GH3 subsamples internally to 4:2:0, then is required to upsample back to 4:2:2, 4:4:4 or RGB to output over HDMI at 1080p. Of course, most people don't look that closely, and for real-life photography it doesn't matter much. Maybe their "real" pro line (Decklink) does it properly, but I wouldn't bet on it.Ĭhroma subsampling really messes with the idea of truly "lossless" capture unless you're very careful. When downsampling 4:4:4 sources to 4:2:2, Blackmagic Intensity Pro 4K does it the worst possible way. When I did a search at OBS's forum, I found some threads with replies recommending the Magewell XI100DUSB for use with OBS on a Mac, but no information about using one with OBS on a Windows PC.īecause you truly are capturing lossless, I think it's pretty safe that there would be no major disadvantage to getting the blackmagic card. I suspect that the Magewell XI100DUSB works well with both the Windows and OSX versions of OBS, but haven't been able to verify it. Lon liked the way it handled video from his camera or switcher, especially for Skype, but was disappointed with it for audio. Streaming and capture software apparently detects the Magewell XI100DUSB as a webcam. Are there any better options than those suggested - what would people recommend? I remember watching a video review for the Magewell USB Capture HDMI XI100DUSB device on "Lon Seidman Reviews Tech" at YouTube. Out of interest, if I wanted to reconsider my options and think about getting a usb or thunderbolt device - what would people recommend? The only usb or thunderbolt devices I see which claim uncompressed 1080p 60fps are theĪgain I want this to work with OBS and be tried and tested by others. So it looks like the blackmagic or magewell are probably the best bet for cards. If I am going to take a chance on Chinese, I would expect it to be at lest half the price of the Blackmagic. Surely to compete with a brand name they must at least be cheaper. Whats more I can't understand why these Chinese cards are in many cases more expensive than the Blackmagic. That is the problem I don't see many reviews or community support forums for these Chinese cards. Startech's 1080p60 card is the Startech PEXHDCAP60L. With Timeleak, I think you are pretty much on your own for support. Blackmagic is headquartered in Australia, with branches in various other countries, provides drivers, support, and often software for the products they sell. Micomsoft (Japan) and Startech (Canadian, with branches in various other locations worldwide) sell some of Yuan's designs, but they provide the drivers, support, and often software for the products they sell. Many of them are lacking in the area of customer support. ![]() He began doing this with his very first post. Be aware that ezcapper's main purpose for being a member of this forum is to promote various capture devices from Chinese companies. ![]()
