I was curious sanlyn. In the original AVISynth scripts (or the 4th one) you created for HHGTTG, you have:
AssumeTFF().TFM().TDecimate() I was always doing BFF with the DV input assume the analog ATI is TFF? I'm going back to some of the bad content, especially Hitchhikers one as the DVD version of this video is missing some good parts so decided to go back to trying to cleanup this VHS version. Started to step thru it and saw that so was curious. Also in your two step process the first step you say to save as Lagarith YV12. How about the second one. I try to avoid YV12 as much as possible leaving as YUY2 but understand with some of the scripts you use this may be necessary. Thanks. JR |
Forgot one part. On the first script again, is it assumed the footage is progressive?
Import("D:\Avisynth 2.5\plugins\ContrastMask.avs") DirectShowSource("E:\forum\jriker1\Cap1\HHGTTG.avi ") Trim(0,122)TComb() CheckMate(24) Santiag() AssumeTFF().TFM().TDecimate() ConvertToYV12(interlaced=false) So above, last line of what I copied in here, you assume the footage is not interlaced. Curious why. Is the assumption the footage was originally progressive and TFM is returning it back to that state? From what I can see TFM has it's own deinterlacer for footage it can't pull a progressive frame out of. Is it better to use one of the better deinterlacers like QTGMC as part of this process? Looks like TFM supports external deinterlacers. Thanks. JR |

The thing to remember about the above code is that all of the filters in Step1 can work in both YUY2 and YV12. Quote:

- Import to AVI Lagarith - AVISynth with just: import("QTGMC-3.32.avsi") AVISource("filename", pixel_type="YUY2") AssumeTTF() QTGMC(preset="very Slow") - Then move the resulting file into Premiere Pro and use NeatVideo to clean it up and chop off the edges that have flaws. Save to H264. JR |

QTGMC requires YV12. "Very slow" is very strong filtering ans usually over smooths. Add NeatVideo and your video will look like a posterized cartoon. Deinterlacing telecined/blended video results in duplicates of progressive frames, duplicates of telecined frames, and duplicates of blended frames. Many players will choke on that at 59.96fps. Works only with purely interlaced video. |
Thanks for the info. For reference, QTGMC is YUY2 or YV12.
http://avisynth.nl/index.php/QTGMC See requirements on the right. I was originally concerned about "very slow" and the developer said it was light cleaning but will probably back off to something less intense. Wanted the best quality deinterlacing but saw also that it adds some level of cleaning automatically. Not sure why that choice was made by the creator. JR |

So I am still here. :)
I have all the tapes converted to lossless digital format and paused for a while. I have now loaded the first one into Premiere Pro and have used an adjustment layer to clean up the coloring thruout the various pieces. Plus using NeatVideo for cleanup. I am going to export TFF interlaced and then load into QTGMC thru AVISynth to deinterlace into it's final format. Question I have right now, what should it's final format be? I notice a lot of codec come and stop being supported and as MS updates their OS versions, some won't work anymore. Any recommendations for what codec and container I should be using to archive these materials? Not concerned with lossless as long as I can maintain decent quality being VHS originals of course. Thanks. JR |
