Hi guys, can anyone recommend a USB HDMI capture device that is confirmed compatible with OSSC?
I have Avermedia LGP Lite and I can confirm It’s NOT working with custom RGB resolutions/scanlines/refresh rates from Sega consoles.
You can see the issue here: https://youtu.be/l9LXK4nXBDA
I want to sell it and buy a compatible one.
Thanks!September 6, 2016 at 8:47 AM #8768
I’m trying to capture Sega Saturn with a Blackmagic Intesity Shuttle and it’s been giving me fits. The only time I can get an image from the OSSC is when I first turn it on and see the “GRAY” As soon as I choose the RGB SCART input it dies and I can hear audio still but no video.
This BM Shuttle is notorious for needing exact timings in order for it to work. Thankfully I can set custom timings and that’s worked for me in the past. I do have a “generic” SCART to HDMI scaler that worked fine before although I capture at 1080p. Anyone have any ideas why i get image when I first turn the OSSC on and not when I switch to Saturn?September 6, 2016 at 10:56 PM #8772
Test pattern is 525-line signal @ 59.94Hz (fully compliant with CEA/HDMI timing), whereas linedoubled Saturn 240p output is 526-line signal @ ~60Hz. Very close, but apparently not close enough for some capture devices.September 11, 2016 at 5:09 AM #8809
The Elgato Game Capture HD (not HD60) supports 240p through composite (but not through component or S-Video), and because it converts to HDMI internally, it should also support 240p through the HDMI port. (But it stores 240p as 480i, so you may wish to deinterlace in post.) Maybe buy one from a place with a good return policy and let us know what you find?September 11, 2016 at 6:53 AM #8811
I have an Elgato HD, Roxio HD Pro, and an internal Avermedia Live Gamer HD I can test when I get a unit, which should be in the next batch. I know previously with the Avermedia, I would have to go through my Elgato for 240p and my Roxio for 480 to get the Avermedia to register the content. We’ll see what changes with the OSSC.September 11, 2016 at 1:45 PM #8814
Slightly off topic, do you mean the Elgato Game Capture HD? The one with analog inputs as well as HDMI? If so, I’m curious how you go about capturing 240p. As far as I know, it encodes 240p content as 480i before it even reaches the computer. And, of course, it won’t capture 240p over component so that limits it to composite and s-video. I have to then run the content through an avisynth script to deinterlace it and get it back to 240p.
Also, since it encodes it in 4:2:0, the color resolution is garbage by the time I get it back to 240p (I convert it to 480p/720p in avisynth, depending on what I need it for, to keep further color degradation to a minimum), flickering up and down since the capture was originally interlaced. They say their device supports “240i,” which isn’t a thing (and also indicates they really don’t know what they’re talking about) but the fact that it automatically turns it into 480i means it supports it like most HDTVs do– poorly.
In any case, do you do something similar when dealing with 240p source material, or is there an easier way to do this?
This is one big reason I can’t wait to get an OSSC. I want to be able to capture 240p content in a better way.September 11, 2016 at 3:45 PM #8819
I’m not really sure how well I can help you with that as I’m not super knowledgeable as to how these things work. I tried plugging in an S-Video Snes connection to my Elgato. It registers it as either 480i or you can use a setting to convert it to 480p (Which when capturing looks much nicer). Same with Composite although it looks rubbish either way with Composite. I cannot capture true 240p with the Elgato HD. Although, I don’t capture much for 240p sources anyway. The extent of what I intend to upscale with the OSSC are Snes, N64 (Both RGB modded), PS2 (For PS2 and PS1 games), and Wii (For Wii and Gamecube games). This will only be using either Scart input or Component input. While, I’m not very knowledgeable on this subject I’m pretty sure everything I intend to use it for is already 480i or higher?
When dealing with 240p source material with the Elgato, I used the 480p option, sent it to my Avermedia, and then captured it just how it came out from that.
Sorry if I am unable to answer that question.
Also, if I was wrong about something (Which I probably was), please correct me as I hardly know what I’m talking about.September 11, 2016 at 5:38 PM #8821
As far as I know, the vast majority of SNES games output 240p. (I think RPM Racing is one of the VERY few titles that use the hi-res interlaced video mode) N64, PS1 and Saturn can go either 240p or 480i, sometimes even within the same game. I think pretty much anything after that is strictly 480i/p.September 15, 2016 at 11:29 PM #8859August 18, 2017 at 3:59 PM #14480
It would be very nice to get a compatibility list going including compatibility with all output modes of the OSSC. I have a only one capture device which is the external Elgato HD60s. I have had success getting it to work with RGB signal from my SNES and 2x scale output but it does not like 3x, 4x or 5x.. I’m going to do some testing with other consoles and other inputs as well like to see how it handles the Gamecube 480p signals and scaling from OSSC. I have an acceptable streaming / youtube setup for SNES and I assume other 240p RGB signals using this cap device and a BenQ 32inch 1080p console gaming monitor that has 0-1ms input lag so pretty much nothing. It is as close to a CRT as I can imagine. In 2x the monitor displayed the game stretched but I was able to find some settings in the BenQ like overscan, aspect 4:3, and a smart scaling feature that let me blow up the image to roughly fill the vertical part of my screen. Captured video looks quite good as well.
It would be awesome to find a capture card/box that was not picky at all about OSSC output and just captured it all, but that may be asking a bit too much.August 18, 2017 at 10:09 PM #14502
