This looks amazing. Honestly, I can only comprehend like a third of what you're saying it will be able to do with all these features, but still, a LOT so far seems like things I could definitely put to great use!
I'm half way sure it already sounds like it can do a lot of the below, and others have already mentioned some of these as well, but I'll list my dream (probably unrealistic) wishlist anyway:
• 480i to 480p+
• 480i to 240p
• every type of signal (<1080p) to 240p lol
• 480p to 1080p/4K still needs some love. I don't know if it's filters (eww) or what, but it's still pretty nasty on a 1080p/4k set, even with supplementary scalers like Extron DSC 301 HD, DVDO's, etc.
• CV/YC inputs!
• Transcoder with scaling or just passthrough conversion (YPbPr> RGBS, RGBS > YPbPr, CV>RGBS, RGBS>CV, YC>RGBS) -- this would literally get rid of my ~20 different transcoders/converters, most of questionable age, NONE easily available to even find to buy, which I've been searching out for ~3 years now (and yes, I'm dreaming this can be used for digital AND analog uses fyi)
• Sync correction/rebuild w/ corrected passthrough (i.e. make any console work on any analog BVM CRT's by Sony, Ikegami, JVC, etc. ALL of which can have issues on certain consoles - that 'horizontal slices in the vertical sync block' problem)
• Dejitter for NES/SNES and whatever else needs it
• SEAMLESS 480i/240p switching
• I'm probably forgetting some...but literally just going through what my current equipment circa 2000ish does or even equipment I STILL can't find on eBay for sale all these years later because it's unobtanium
And my own personal pet peeve I've mentioned before is:
HAVE ALL THE PORTS ON THE BACK!!! pretty pretty please. Picture this: you're going to have a beautiful professional piece of video scaling equipment, most likely showcased in your living room, your den, or your office. It's the most amazing thing in there. Forget your Xbox One X or PS4 Pro, forget that DVDO VP 50 Pro you had to stalk eBay for 14 months to get and it STILL cost you $400+; forget your $3000 OLED TV, your Denon X6500, your Analogue Nt mini, Mega SG and/or Super Nt. Forget all those subpar toys - it's all about wowing your company with your awesome new OSSC PRO, which yes my clueless company, that is what is making the magic happen on the TV right now. Aren't you impressed? What? Your head feels like it's going to explode because that old video game system can't possibly be that crispy on that 75" flatscreen. It's impossible that those 20-30+ year old retro video games can be made to look this brand new with pixels as sharp as a razor. Mind. Blown.
You're then going to point to this mindblowing piece of electrical genius...and it's going to look like a friggin frankenstein DIY project. You're going to have at the very least a big old non-bendable, non-hideable, HUGE (by today's plug/connection standards) SCART cable sticking right out the side of it in plain view. Most likely we'll start using the other 2x ports on the side as well and there's going to be stuff sticking out from there too. All different color cables. Going in all sorts of weird directions (because you know high quality proper shielded cable doesn't like to bend). The OSSC PRO will probably be lifted off the shelf and all crooked because the wires attached to it weigh more than the actual scaler. It's going to look like a circuit board with a mess of wires sticking out of it like a giant floating spider ready to eat their young. It's going to be scarier than RE2.
OR, you could just put all the ports on the back and it can look nice and clean and REALLY professional, just like its namesake. lol. Yes, I'm being a pain in the ass (and hope at least one other person giggled at the above), but seriously. Pro equipment should at least attempt to be user friendly in regard to wire management, these things are most commonly prevalently displayed in our living room areas - the most used part of the house. At least have all the wires run out the back of it.
I have two OSSC's. The one on my server rack I finally found out if I sandwich it in a 1U space between two other pieces of equipment, then double side tape it so it stays pointed straight forward and doesn't rotate at least, then zip tie the SCART plug down (which always likes to come loose), I can at least make sure it stays put with everything plugged in. The one in my living room I literally hide in a drawer so my entertainment center looks at least half way believable that an adult lives there. Then when people want to play some games I'll then pull it out (cables are all there and ready, just pushed to the back of the shelf in the shadows) then plug in the all the wires and we play some games. It then goes back in the drawer afterwards.
