OSSC - Open Source Scan Converter

So it's arrived and out of the box it plays nicely with my Elgato HD 60.

I think I've got a shit load of fiddling to get the best out of it but I'm very pleased with the results so far, plus it keeps the aspect ratio unlike my old SCART to HDMI convertor

 

Good capture test sample, I take it you had scanlines on during the video? Now that they've come down in price I might grab one in the future, as I've now seen a few people had it up and running with Elgato software now.

 

That said I've seen a few PS2 and Saturn videos where it doesn't work that well with certainly types of video display used in games and it also can have problem with games that have transition between resolutions. One channel did find a transition fix for Megamix on Saturn but it does come at the cost of quality:

 

 

Certainly looks ideal for the 16bit systems, like the SNES, MD and NEOGEO after tuning, this video demos someone tuning it for the NEOGEO:

 

 

The end result on Fatal Fury for the NEOGEO is perfect in that video, but I'm come to the verdict you won't get that with every game, certainly not on later systems.

I switch between the HD60 and a Hauppauge Rocket - the latter deals well with a wider array of resolutions than the Elgato, and seeing as most old games run below 1080p it records them all at 60fps. Finally, as it all goes on Youtube, recordings maxing out at about 12-15mb bitrates doesn't matter too much, as that's more than YT outputs anyway.

Yeah, 1.6 has been the latest hardware for a while now, and it's excellent. 

It also keeps getting better with every firmware update too. It's so good, that I'm a bit like "why do I own a framemeister as well?"

Is it possible to connect component, scart and the component audio to an av receiver at the same time?

 

I want it mainly for my older xbox and wii for gamecube games.

 

I read a post on the OSSC site with someone who had issues with some xbox games but I think as it's soft modded I should be able to change the default resolution to 480p by switching to NSTC.  In worst case I could let it pass through just converting to hdmi.

Not 100% on connections via AV receivers, but sound input is via SCART for that particular connection, and via a jack input for component, so both can definitely be fully hooked up at the same time.

 

I find the OSSC itself doesn't have many issues with games and can output all manner of weird and wacky resolutions - it's more the TV/monitor you run it to that causes issues. Modern TVs aren't well equipped for varying SD signals in the most part. Admittedly I'm not sure why OG Xbox would cause problems, but there you go. And yeah, softmod means you can run at 480p, so most everything will be fine.

So finally decided to pick one up, now the system been out for a while and there have been a number of fixes for it. Only really tried it with the Sega Saturn and a RGB modded Nintendo 64. The system doesn't support either S-Video or Composite and they will not work with it even if you use a scart adapter. The output itself is lovely, however it really is pick and mix, which Line X modes works with each game. Running games in 50Hz or 60Hz also affects this, certainly not a plug and play system and I'm still learning which options tweak what to improve the picture, this channel has some great tutorials for system set up: https://www.youtube.com/channel/UCzeJi0ToNcKX4uLBOyjJVtA

 

Here's a brief overlook of me testing a PAL and NTSC Sega Saturn game on it, will be doing more, certainly won't be throwing away the old scaler as it does a lot of things the OSSC doesn't do:

 


So far every game I've tried with the system has worked, not that I've tried many. Make sure you get a remote with it as navigating the menus is a nightmare using the unit button. I got mine for £139.99 from Amazon and it included the remote and power pack and a handy quickstart guide, came installed with 0.82a firmware:

How much did you save by not getting one directly from VGPerfection?

 

I wouldn't take the risk, myself. 

 

About £40 roughly, from what I can tell VGPerfection, just import their unit stock like everyone else of the OSSC, all parts and units seems to come out of some factory in China. Just cause they get mentioned by a few YouTubers doesn't make them any different to any other supplier. All the units I've seen are using the same parts, so I suspect the manufactor cost of the unit is rather cheap, now they've been producing them for a few years. Once I realised that buying one for VGP just seems like a brand name.

Right so here a quick OSSC comparison with the old scaler, now the OSSC does have flaws when it comes to interlaced content and games that changes resolution in-game. Still getting to grips with it and I won't be totally getting rid of the old HDV-8S scaler as it still has a lot of uses. Also the Elgato HD60 Pro doesn't play that well with the OSSC, so I can only catch in Line x2 mode for most console, some Saturn games the Elgato does support at Line x3. Having capture export issues also with the Elgato, but the master videos are fine.

 

Here's a look at two X-Men vs. Street Fighter videos we did, first is OSSC and second is our old scaler:

Old scaler HDV-8S

 

One other changes is the OSSC video is using the master Elgato .ts recording, where as the latter is using a mp4 export. I had some issues getting shotcut to export the raw file, once I got some advice from the guys who do shotcut, I got it sorted and it does actually improve the video quality even more. Done side is it requires disabling parallel progress, which slows down video progressing no end.

Right so I am going to really give the OSSC a work out with just about all the main Nintendo, Sega and Sony consoles and I start with an in depth look at how it handles a NTSC Super Nintendo unit and a selection of games on the system, which includes most later chip sets and the Super Gameboy 2. No interlaced games in this video as so few games use it on SNES and the only ones we have are Power Drive and Desert Fighter, which will appear in a PAL SNES video, which is to follow.

Anyone have any luck pal PS1? The picture on mine is pretty awful, overscan cuts off bottom and top of screen.

 

What mode you using? Line X5 is cropped in PAL but Line X2 should be fine, haven't tested it with a PAL PS1 console. I have captured a PAL PS1 game on PS2 without issue game was Overboard video here, this was Line X2 mode:
