![]() if i'd pad 4 lines (2 top 2 bottom) i could upscale pixel accurate 2 x 448. i have the luxury of a native 900p screen. every 2.4107th or 2.25th uses a 'wrong' line offset. when you upscale 448 or 480 to 1080 you still have fractional line ratios (2.4107 or 2.25) when resampling the output to your native screen resolution. a 240 backbuffer with interlace (2x) would produce 480 correct interlaced lines. the thing with the lines is, it can not be scaled and interpreted correct. What do you think about Bob, Weave, Auto, None de-interlacing options, and do you think they can be further improved? IMO, all de-interlacing options in PCSX2 have their minuses, like loosing spatial resolution, blurring, shaking, or combing, but mostly Blur. #FORCE PS2 240P 480P PS2#Personally, I still think that hardware PS2 on a Sony Trinitron CRT looks the best, but PCSX2 is getting there. This will display the content exactly like a CRT in its original resolution, but will have terrible comb effect and flickering, much worse than "Weave bff". #FORCE PS2 240P 480P 240P#I think PCSX2 lacking a true NONE option where it displays Even 240p field then Odd 240p field, without filling the black lines like the regular None does. This will result in a sharp and clean image much like a progressive image looks like on a progressive LCD monitor, but with visible comb effect in motion. This only looks good on static images, since Weaving is much like Blending but without blending. Make the Window Size to x2 integer of the reported vertical resolution, for example 1200x896 if the reported is 448i.Īlso, turn off "Texture Filtering of Display" in GSdx Shader Configurations. If you are interested to see how the original image looked on a CRT without extra blur of deinterlacing filtering or loss of resolution, set it to "Weave bff". #FORCE PS2 240P 480P FULL#strange.Įdit: Apparently some games run at 30fps and output 60fps interlaced, so None or Weave will actually look like full frame 448p progressive at 30fps. The result looks as though it is half the resolution of the intended 448 image with slight flickering, very much like Bob but less filtered.īUT, in some games (GTA-VC, THPS3, SSX3), None actually looks like progressive content while still reported as Interlaced. * None: Doubles the line of a single frame from Even lines 240p to 448p and displays it, then doubles the line of the next single frame from Odd lines 240p to 448p and displays it. * Auto: Tries to find the correct setting for interlaced content, 99% of the time it selects Blend bff.īut there are games that display progressive content but report Interlaced, in these games Auto will select None. Quality depends on the quality of the resizing filter, but like blending it’s blurry since half the vertical resolution is lost in the upscale. Also shifts the field slightly up or down so the picture won’t appear to jump up and down slightly. * Bobbing/line doubling: Doubles the height of each field, effectively making each field its own frame. Obviously very blurry since you effectively lose half the spatial resolution as well as half the temporal resolution (blending halves the frame- or fieldrate since every two fields are combined to one frame, so instead of 60 fields/s you get 30 frames/s). Usually causes funky ghosting artifacts (since in an interlaced clip, each field is at a temporally separate point). * Field blending: Takes consecutive pairs of fields and blends them together into one frame by averaging pixel values. Guaranteed to have artifacts unless the clip is completely static. Quote:* Weave: Does not really deinterlace at all takes pairs of fields and puts them together (every other line) to one frame. I'll try to explain in detail what every de-interlacing option in PCSX2 does, but I may need some correction.įirst, here is an old quote from the forum: ![]() We want to fix how interlaced content looks on an progressive LCD screen, this is where De-Interlacing comes in. Thus, Even 240p frame followed by a Odd 240p frame which is interlaced content, looks great on a CRT but weaved/combed on an LCD. ![]() ![]() When HDTVs popped up, interlaced content showed sever stripes (combing) in motion on the progressive HDTV display.īecause LCDs use "sample and hold" to display a picture, while a CRT draws a single line to to bottom vertically per frame.Īlso, on a CRT a single 240 frame with black lines every other scan-line looked coherent (NES, Genesis and SNES for example), Quote:Back in the PS2 era most TVs were CRTs which were designed to display interlaced (480i) resolution, and everything looked perfectly fine. ![]() Since most PS2 games run in interlaced resolutions of 480i (448i) I think each and every user of PCSX2 should clearly understand the mysterious F5 button and what is does.Īnd since I didn't find a thread that explains these de-interlacing option thoroughly with a good following discussion (hopefully), I decided to create one. ![]()
