| Hi all, Does anyone know the best settings to use for Donald Graft's "Smart Deinterlacer" filter? I'm trying to get the best sharpness and detail in some small motion graphics. There are quite allot of combinations of settings in this filter's interface panel. So far in my tests with this filter versus the built-in deinterlace filter that comes stock in Vdub, I'm getting better results with the built-in filter, but I'm still needing a bit sharper detail rendering for my small motion graphics. Thanks for any input, numetro |

| I've found the idea interesting when i've discovered and tested this filter. Unfortunately, i've quick discovered an annoying side effect. If you have noise in your video, on static part of picture, area filtered may flicker/move between picture because of noise making computed result sometime under sometimes over the threshlod. Visual result of these "moving" areas make me discard this filter. |

| Hi jsdpr, I'm working with created still graphics that have been animated with motion effects in Adobe Premiere. The result with the graphics when they are moving contains severe interlace lines. The built-in Vdub deinterlace filter and the installed "Smart Deinterlacer" filter are doing a pretty good job in my tests so far, but I'm still looking for the optimal settings in either or both filters to keep the small motion graphics very sharp. Since these graphics are created from sharp still photos and created graphics in Photoshop, they remain very, very sharp when they are still, and now after running the motion video of these graphics while moving through these filters in Vdub, they are greatly improved and the evidence of the interlace lines is nearly gone, but the moving graphics are still not as sharp as it seems they could be. The alternative that I've been working with is doing stop frame animation, which keeps the graphics perfectly sharp while they move, but the process is excruciatingly laborious... creating 130 layer PSD files, advancing each layer ahead by 12 pixels, then importing all of those layers in to Adobe Premiere in one, four and eight frame clips times like a thousand and that times 30 files is unbelievably tedious. Earlier today I found the best setting so far in the Smart Deinterlacer filter that has given a slightly better rendering of these motion graphics so far, and I found the Donald Graft guide to the meaning of the different settings in this filter, but these descriptions are very abstract, and the forum on the Donald Graft website seems somewhat inactive. So that's why I'm checking to see if anyone knows the best settings for either or both of these filters to keep small details as sharp as possible. Thanks, numetro |

| Also, forgot to mention... I wanted to ask if you've tried the XMedia Recode encoder for its deinterlace filter... there was a recommendation for this over the Vdub deinterlace filter elsewhere on this forum. I had another recommendation for the TMPGEnc encoder, but when I went to download that one I got a virus warning... but others have installed this and apparently got great results deinterlacing with it... have you heard of or tried that one? Thanks, numetro |

| Be clear : When i'm talking of moving areas, i'm not talking about the picture, but the areas filtered => When what's in the picture stay identical, but filtered areas move because of noise/threshold. Now, i don't actualy work with things wich need deinterlacing, but, for now, if i have to deinterlace, i would use the QTGMC avisynth filter. I don't know XMedia Recode, and don't use it. |

| Hi jpsdr, I have to admit, I'm having a bit of a hard time following your terminology... but I think I understand. Thanks for your info. numetro |

| The problem with interlace is that there are so many types. So not one deinterlacer is capable of supporting all interlace video. Only option is to somehow identify what type of interlace your video has and get a deinterlacer for that type of interlace. You could try others but the results can from no change to extreme change where cannot see what the video is playing. If you intended audience is social video site i have no idea since don't use them. But assume would need to deinterlace for pc playback by others. If for optical disc home player playback then easy way would be to leave interlace and let the hardware deal with it. Saves time and hardware normally has better results in real time than doing same with software. Is there a tool that can identify what type of interlace each video has ? If there was such a tool (please do tell) deinterlacers would also have those interlace types listed as, are supported for deinterlacing that they don't seem to do now. If need to do with software there could be a long time finding the best deinterlacer for the video you have. Have you the time or will to do this ? If for same process that each video is from same source then would be an advantage. But for different video sources would take a lot of time. Would still need to find all deinterlacers out there in hope one will work for the video you have. |
