I'm guessing that some form of noise filtering has occurred because I see remnants of tape noise rather than the usual noise itself. At least it appears to have been played/recorded using a line-level tbc of some sort, so give the maker credit for that. Because most football game broadcasts last longer than 2 hours, I assume some commercials or other material was cut from the original MPEG transfer the AVI video looks to be over filtered in some way. From there, it appears to have been captured directly to MPEG2, perhaps using a DVD recorder, at a 2-hour bit rate of 4500 VBR. From MediaInfo off the VOB and looking at the avi sample: the original broadcast was recorded to analog tape. Depends on how far you want to go with it. After making other repairs, youy would have top re-encode for DVD or other output. The original video isn't horrible, but it would require lots of effort. I did no denoising or artifact work, and no sharpening here. This would be one of the easier scenes, but unfortunately VHS color and levels vary wildly from scene to scene. It's improved, but "correct" with video is a matter of personal preference. While the color in the original isn't all that bad, it looks as if it might not have been broadcast as the best the creator could have devised. It depends on what you expect for results.īelow, I decoded the MPG sample to lossless AVI and made up a quick color and levels adjustment with ColorMill and gradation cirves, to get a "before & after". If you decide to pursue that avenue, there are many members who can help.
This kind of repair and cleanup involves a learning curve and takes time. Opening the videos directly into VirtualDub will make debanding and other repair more difficult. their image repair filters concerning banding and other problems mentioned are not as effective as those in Avisynth.
#HOW TO RUN WARPSHARP SOFTWARE#
I would advise that you not attempt correcting artifacts in the usual NLE software such as Pinnacle or Vegas, etc. One could also correct the low contrast and/or higher than nomal black levels in AVisynth, buyt nthe color problems wouyld respond best to filters that address specific color ranges, such as ColorMill or gradation curves. Avisynth wouyld be the best tool for that. They have to be processed in their original YUV colorspace. There are many filters for those tasks, but problems such as banding, block noise, etc., have to be removed by decoding the VOB or combined MPG intolossless media (using a lossless compressor such as Lagarith to save disc space).
