Oh great I might pick up an OSSC 1.6 then, is there such a thing as OSSC+XRGB too?Fudoh wrote:The OSSC introduced a new sampling option for 480p sources a little while back (changing the horizontal number of samples taken before the upscale), which should make the x2 result (OSSC+DVDO) even better than before.
Pixels on the XRGB-3 are not really uniform, since the upscale from the PSP's active image isn't integer and the XRGB-3 doesn't do proper filtering. Through the DVDO you get uniform results with a little less sharpness in comparison.Less well scaled? What does it mean?
You can use the Framemeister to increase your display's compatibility with some of the OSSC's output modes, but you shouldn't use the FM for rescaling the OSSC's output.Oh great I might pick up an OSSC 1.6 then, is there such a thing as OSSC+XRGB too?
Oh but I don't know if you remember but the XRGB-3 offer both Integer and non-Integer Scaling. The XRGB-3 calls Integer Scaling "DOT by DOT" and you get 1920x1088 in that mode (480x272 x4 = 1920x1088). You were surprised when I told you that integer scaling even worked with the PSP.Fudoh wrote:Pixels on the XRGB-3 are not really uniform, since the upscale from the PSP's active image isn't integer and the XRGB-3 doesn't do proper filtering.

I don't have an OSSC nor a DVDO, but it'd be intersting to see how it pans out on the PSP:ZellSF wrote:Not really, I want to see how it compares but connecting my capture equipment now is not easy.Fudoh wrote:Did you try the since added "double samplerate" option with the PSP?
Right - I remember, but the for the PSP that's just relevant for the vertical resolution, since the XRGB-3 does not apply resolution optimized sampling for the horiztontal axis. In comparison the XRGB-3 should still perform pretty good since it should be a full 4:4:4 processing path, where as the DVDO converts to 4:2:2.Oh but I don't know if you remember but the XRGB-3 offer both Integer and non-Integer Scaling.

no need for captures. If you have a running PSP with the OSSC/DVDO combo your subjective impression would be good enough.Not really, I want to see how it compares but connecting my capture equipment now is not easy.
Any DVDO models out there that does 4:4:4?Fudoh wrote:In comparison the XRGB-3 should still perform pretty good since it should be a full 4:4:4 processing path, where as the DVDO converts to 4:2:2.
Any examples? (beside the obvious PSP scaling I mean).Fudoh wrote:you can do so much more with these two compared to the old XRGB.
they all have the option to output 4:4:4, but the internal processing on all units is 4:2:2.Any DVDO models out there that does 4:4:4?
The OSSC/DVDO combo is the best solution for ANY system. The only thing I would prefer a FM for is 480i processing. It's quite good on the DVDO already, but the FM is better.you can do so much more with these two compared to the old XRGB.

How much would that take away from the picture quality compared to something like the XRGB-3 which has 4:4:4 internal processing?Fudoh wrote:they all have the option to output 4:4:4, but the internal processing on all units is 4:2:2.

it gets more obvious the higher your source resolution is, but with a 480x272 base resolution, you have to be close to the screen to notice it.How much would that take away from the picture quality compared to something like the XRGB-3 which has 4:4:4 internal processing?

If you want to use Line2x480p mode then you're pretty much left with the Edge alone as far as DVDO's scalers go. The VP50's need quite a bit of tweaking to accept that signal and if I remember correctly there are some strings attached too (an article on the VGPerfection website goes into more detail).Lawfer wrote:What DVDO model would give the best picture quality (when used with the OSSC double samplerate)?

I was talking about the Edge Green I think, apparently it has issues working correctly with 240/288p video from RGB, S-Video or composite sources.Xer Xian wrote:Yes, the Edge has an increased processing lag on a few systems (I think Saturn and PCE are among these). This was reported on a pre-OSSC era though, as far as I know no one has verified if the added lag is still there with line-3/4/5x240p pre-processed signals (or someone has and did not post about it yet). Of course, if the bug was down to the specific frame rate outputted by these consoles then nothing would change..
No one has reported anything wrong lag-wise about the Edge's 960p handling as of yet. I should be able to test one in a few days btw.
yeah, but you wouldn't want that anyway.apparently it has issues working correctly with 240/288p video from RGB, S-Video or composite sources.
So which DVDO should I get then?Fudoh wrote:yeah, but you wouldn't want that anyway.apparently it has issues working correctly with 240/288p video from RGB, S-Video or composite sources.
The Edge disables the detail- and edge enhancement options while in gamemode. On the 50Pro and on the iScan Duo they're available. Not sure about the Edge Green, sorry.
But I don't want to make a collection of DVDOs, I just want to get 1 that will give me the best picture with this PSPgo + OSSC Line2x 480p + DVDO 1080p setup.Fudoh wrote:get what's available. Pricing is incredibly stable, so you switch if you find another one.
Got it thanks!Fudoh wrote:Your best option is the VP50Pro, but at the same time, it's the one hardest to find and with a tendency to be the most expensive one.
I just tried some games and my impression is just that it looks better for 3D games and worse for 2D games because it looks softer. Also much less affected by sampling phase, which is annoying to deal with. I actually tried making some captures but there were some weird scaling issues with upsample2x I need to figure out. I'll look a bit closer later. If you're curious here's the issue, upsample 2x off:Fudoh wrote:no need for captures.

If he only wants it for the PSP, wouldn't the Edge be equally good (and cheaper)? Isn't the VP50 Pro's disadvantages compared to the Edge only when deinterlacing and/or playing consoles with odd refresh rates?Fudoh wrote:Your best option is the VP50Pro, but at the same time, it's the one hardest to find and with a tendency to be the most expensive one.

I don't have a XRGB-3 and I'm not sure there's that many people that kept both a OSSC and XRGB-3 (OSSC is a replacement for an XRGB-3 in a lot of ways).Lawfer wrote:How does it compare to the XRGB-3?ZellSF wrote: I just tried some games and my impression is just that it looks better for 3D games and worse for 2D games because it looks softer.
as mentioned above, you lose the edge/detail enhancement controls on the Edge when setting it to gamemode. If you don't need these controls, I'd say it doesn't matter wether you get a VP30, VP50, Edge, 50Pro, Edge Green or iScan Duo - just get what's available (back to my point above).If he only wants it for the PSP, wouldn't the Edge be equally good (and cheaper)?

Better than the XRGB with it's ~21.4ms.Fudoh wrote:I think it adds two frames, but it's been years since I last had an Edge, so somebody else might want to confirm that.
