Well, it looks like I can stream 4K without any issues. That 1GBPS connection is actually useful after all. Just a shame I have no 4K monitor. I have a question, is the ghosting present on the below screen shot a result of up-scanning 240p to 4k resolution or was the original like that too?
Phew had me scared for a second thought i left on my custom anti aliasing art i call 4x3_checkers_med_Stevacus it's like scan lines without seeing scan lines if that makes any sense, but you can barely see them unless its super bright, even than its hard. i think it may be be a combination of resizing and youtube, though i get a bit on the h.264 video but not nearly as much, and HEVC looked a bit better but a 7 times smaller file. ill jsut post screen shots to show you i hope png is ok qaulity. this is what the original video looks like at 2880x2016 taken from a Divx player screen shot (my crt does resolutions up to 3072x1792 but scaled down videos look crisper that way though, should not effect the screen shot) all of these pics will be 2880x2016 btw so you might need to *view image* ORIGINAL 15.6 GB AVI 320x224 recorded with mameUI viewed at 2880x2016 HEVC 2880x2016 877MB H.264 2880x2016 6.?GB Youtube @2160p
Actually the Original looks much better than the re-encoded versions. They do have a lot of ghosting on them. But when you concider that the original is a tinny 240p image, they've come out pretty well.
Thanks man . Yes the original does indeed look much better still i am very impressed with the outcome of the scaling, as the HD4k part of the HYPER EDITION series continues i hope to come around some techniques to avoid the ghosting, I believe my next video will be magician lord or turtles in time though requests are welcome.
Very jealous - our politicians have come out and said that 25mbps is adequate for today's internet usage and can't see any application needing 100mbps or more today or in the future when designing the successor to our current telecommunications network @coal stepping: The originals look a little blurry, but as Yakumo said it's symptom of it being a 240p original! That's something that bugs me when emulating older titles - would be nice to have those pixels deliciously razor sharp at a 4k resolution!
I'll tell you what though, none of those pictures above have anything on running the games at native resolution on a hdmi CRT thats professionally calibrated (i use Atrise Lutcurve), it might be scaled up but it's scaled up by the CRT not the video card, imagine the 2880x2016 image with out the ghosting and even blades look rounded and not edgy. I actually have a lot of nice snap shots on my PC i use as an arcade unit out on the side of my dance floor but someone ripped out the power switch wire (nothing solder cant fix) so ill upload those maybe tommarow, I'm about to show you a image i uploaded to facebook so beware that its craptastically compressed and blurry, but if you look at the Japanese characters you should be able to see how they pop out and everything looks smooth, as of this moment you still cant reproduce that effect on current displays, anyone that has an arcade monitor will tell you its just one of those things that a good eye for it can spot right away. The closest thing i can tell you to try is in mameui's advanced menu and scale it by integers like 320x224 would be 9 for 4k than make a custom resolution 2880x2016 set mame to switch resolutions to fit, its a pretty good picture but I'd say 90% as good as native. i also realized that i scaled the original video image based on 320x224 but its shown at 344x240 so i might try doing integers of that and the ghosting might disappear a bit.
If you scale by integers there won't be any ringing (it's not ghosting), but you must use the display's native pixel aspect (square) which isn't ideal for non-square game pixels. The reason video "looks better" on your CRT is that your CRT has limited bandwidth (probably only 540 vertical lines and maybe bandwidth equivalent to ~1280 horizontal pixels if you're lucky). The artifacts are still there but the bandwidth-limited display can't resolve them (a form of reconstruction filter), or other analog characteristics mask them. The blur of the original is probably bilinear interpolation. Interpolation artifacts are unavoidable unless the display resolution is a multiple of the source resolution, or the display has infinite resolution. 4K contains nearly 100 times more information than 240p, so it's incredibly wasteful of resources if you're doing it wrong. As far as 240p is concerned a 4K display does effectively have "infinite" resolution or bandwidth--you could technically scale/resample the video for a perfect pixel aspect as well as have incredibly sharp pixels. This is accomplished by band-limiting each pixel's harmonics when resampling to avoid aliasing (probably requires signal analysis software). Even then the picture won't look perfect up close on a discrete pixel display, but after applying a reconstruction filter (such as your eyes) it will be sharper than a real CRT and no artifacts. This could be even further improved with subsampling--resampling for triad geometry. Oh and a tip if you're going to use pre-packaged interpolation is to first scale to a large integer multiple in order to get more data points (nearest-neighbor is lossless here). From there scale to the pixel aspect's equivalent square pixel window with cubic or sinc or whatever, then letter-pillarbox it.
As always Calpis ty for the detailed information *thumbs up* that makes complete sense. Ive decided to do turtles in times after all. im re-encoding now, but this time instead of using the games native 304x224 integers im going to use the videos 328x240 and resize it by 9 which equals to 2928x2160. hopefully if all goes well the ringing effect will be non existent or at least not visible without taking a good look. I'm actually glad you popped in this makes me feel more comfortable about spending 2 hours recoding the video
In order to keep the correct 4:3 picture aspect ratio you probably don't want to enlarge the 224 lines to 240. The original hardware generates ~320 x 240 but blanks some lines that would fall outside of the safe area. If you're going to fill out the entire 2160 lines from a 224 line source, you'd need to extend 2880 square horizontal pixels out to 3086 to keep the ratio. Personally I'd stick with 2016 lines (slight letterboxing) to avoid vertical interpolation entirely. If according to MAME the game's pixel aspect yields 328 square pixels from 304 native, here's the workflow I'd take: 304x224 -> 5472x224 -> ((328/304)*5472)/2 = 2952x2016
cool. I will try out your method after this re-encode with a small video sample and see what works best, if your method is better i will do another re-encoding I'm already 30% in so i might as well finish it up.
Man, I think my mind slightly imploded with Calpis' technical wizardry. Sounds like you have a pretty awesome CRT display coal stepping - I use an Hitachi CRT for my retro machines and have a beautifully crisp CRT display in my Astro City for PCB goodness (did a tube + chassis swap a few years ago, probably not as good as a Nanao chassis + tube, but it looks stunning compared to the previous tube and chassis fitted by the previous owner ages ago). Looking forward to seeing how the new video build looks as well!
Just for fun I thought I'd see how Paint.net's cubic interpolation would look at 4K: Not too bad at 100%, IMO. The edge pixels aren't very discernible at all. To me this confirms that with "perfect" resampling, a nice CRT filter, subsampling and a retina display in the near future we can get a hyper-CRT experience.
That is what i want these videos to look like... Calpis you swooped in at perfect timing and YAKUMO for spotting the problem might as well kick it in the butt now. i am still processing Calpis reencoding idea but this is HEVC 2928x2160 1.40GB about 35mins seems like its laying right on top the real pixels.
Mangledleg thank you, with the support, we will ge there, Though helpful criticism is excellent as well.
Update Still getting the ringing and I'm having a really hard time telling a difference between Calpis and my idea with the pictures, during video playback though i can tell that Calpis ideas looks alot sharper and pleasant to the eyes. I'll be uploading the video sometime today. HEVC 2952x2016 1.4GB about 35minutes
HYPER EDITION - OVERCLOCKED GAMING is proud to present another HD4k video. This time using a advanced re-encoding technique. This should be as good quality as you can get for now. HYPER EDITION- Teenage Mutant Ninja Turtles - Turtles in Time (4P's ADA)[TMNT2 Hardware ](1991) HD4K
Delightful - will make a note to murder my crappy broadband connection to give it a whirl at some stage this week!
Awesome MangledLeg! Got another one up. Had alot of fun playing this with the gf especially being that its 53% faster. In her words (It's Street Of Rage meets Space Harrier with hover boards) HYPER EDITION - OVERCLOCKED GAMING is proud to present another HD4k video. HYPER EDITION- Riding Fight (Ver 1.0J)[TAITO F3 SYSTEM](1992) HD4K
This game was really hard to record a HYPER EDITION version of as it kept crashing when overclocked, you can't tell the difference but the CPU was overclocked by 5% so technically this is a HYPER EDITION video. I would also like to mention that i have looked around and this is the only proper long play of this game on the internet as other have the video stretched bad quality, game play or no sound HYPER EDITION - OVERCLOCKED GAMING is proud to present another HD4k video.
