  1. So, I've got a PAL DVD (Animated) that contains telecine-like artifacts in some of the video tracks (Ripped using MakeMKV). The main track (full movie) itself is fully progressive at 25fps, however some of the special features have artifacts that resemble what I've seen in telecined NTSC. I have briefly looked into phase-shifting and gave telecide a try to no avail. Not sure what is going on..

    My goal is to convert the videos to progressive while avoiding any unnecessary damage. If I don't need to IVTC with TFM and TDecimate then I assume I could retain closer quality to the original. If I do need to IVTC then so be it, but IVTC'ing the 25fps video brings it down to 20fps. I do have the NTSC versions as well in case somehow IVTC'ing that would be the better option..

    I've attached the MakeMKV rip below

    Field match without decimate seems better
    Code:
    lwlibavvideosource("C:\Users\davex\Downloads\Anything but Down [Music Video].mkv")
    assumetff()
    tfm()

  3. It's not properly telecined. Its poorly converted with blended fields.
    Try somthing along the line
    Code:
    AssumeTFF()
    QTGMC(preset="fast") #or a bobber of your choice
    SRestore(frate=25.0)

    Yes, the srestore version is better

    Hey, i was unable to check in on the attached file but have you tried increase the bitrate? it help sometimes, dont seem to help very much if there are very big sqaure boxes that come up, if thats what you mean by artifacts!

  6. thx for the suggestions! I'll go with Srestore+QTGMC. I noticed you have faster as the preset in your script Sharc, is there a benefit to using fast over the slower presets? I assumed slower = better result.

  7. slower = potentially better results, for most sources it's not really worth it, also depending on the preset additional denoising&co will be used which can be decremental in regard to keeping original details.

  8. Ah, I see. Thank you for the explanation. I plan to use the 25fps progressive videos as bases for upscaling so with that in mind I'll go with a faster preset to keep more fine detail intact.

    Think twice about upscaling. Leave as is unless you have a specific reason why you want to upscale.

  10. So after running that script, the artifacts are completely gone which is great. However, I'm noticing duplicate frames in some scenes. These duplicates are present in the MakeMKV rip from the PAL disc too (Example Frames 941/942 & 951/952).

    I decided to run this script on the NTSC version and all duplicates are gone now and the footage is at 24.975fps. Assuming the original footage was sped up from 24.975 to 25fps for PAL, I believe I've done this right.

    LWLibavVideoSource("A:\Media\Videos\Movies & Shows\Movies\AcceleRacers & World Race\AcceleRacers\Music Videos\NTSC MKV\Anything but Down [Music Video].mkv")
    AssumeTFF()
    tfm(slow=2, cthresh=4) .tdecimate(Mode=0, Cycle=6, CycleR=1)
    vinverse (sstr=2.7, opt=2)
    Crop(26, 2, -24, -4)
    BicubicResize(640, 480)

    Please lmk if there is a better way to do this or if something in the script is wrong.
