Unevenly spaced duplicate frames, but MultiDecimate doesn't quite cut it
Situation: friend & backup nut, busy restoring huge SF collection from rescued external HDs when a fire broke out. (I've adopted the same system since except for the fire bit - also, I *still* think having 14 external HDs is a bit much.)
"Ewwww... it's jerky!" "Did you do anything weird with those?" "No, I just removed the black bars and deinterlaced." "Ah, a decimate problem. I can fix that." After all, I know just enough of VirtualDub, AviDemux and Very Simple AviSynth Scripts to do a standard decimating job. Besides, apart from the slight jerkiness, her copies were better than the ones *I* had. Taking a DVDload home for testing, I found that on all files the leftover duplicate frames weren't exactly evenly spaced. So no four frames + one duplicate (which would have been easy), but anything from one to twelve frames before the next dupe. So I did a Google, found MultiDecimate, tried every setting I could think of for the next two days (including some pretty far-fetched & random ones), but none of those took out ALL the "jerks". When I DGBob'ed a snippet out of curiosity (top first), I noticed that the former odd fields (now: odd frames) were of much lower quality than the former even fields, which might explain MultiDecimate having trouble identifying all the dupes correctly (which is a wild guess. I'm a newbie.) Anymoo: HALP!!!! (Or: "Ideas, anyone?") snippet: http://www.megaupload.com/?d=72UXEC4W (39.6 MB, 43" mpeg2, no audio) Last edited by StickHorsie; 6th June 2008 at 21:45. Reason: typos, catchier title and a little less drama ;) |
