  1. I have this video from a 2007-2008 dvd that I own, which at today's standard is of deplorable quality, is there any way to get the video by removing the black borders at the top and bottom as sharp as possible, removing the interlacing correctly and maintaining a good quality for today's standard?

  2. It is 2-2-3-2-3 pulldown (aka 6/5) used for converting 25fps (PAL) -> 29.97fps (NTSC)
    One can IVTC (InverseTelecine) it like
    Code:
    LWLibavVideoSource("fragment.mkv")
    assumeTFF()
    tfm().tdecimate(cycle=6,cycler=1)   #returns 24.975fps progressive frames
    Assumefps(25.0)                     #speedup to the original 25fps
    crop(8,66,-16,-72)                  #removing the borders

    Good job, regarding the quality, can something be done to make it sharper and get more detail? closer to 720p maybe? make it look nice?
    I have a documentary clip of this same concert as a reference, which has a better definition, if I could get that definition on this DVD I would be more than satisfied.

  4. You could try to denoise/degrain and add a sharpener (don't overdo). You won't get or see significantly more details by doing this though, nor by upscaling. What isn't there can't be recovered. One cannot convert lead into gold.
    (Maybe someone has an idea with AI ...).

    Edit: Clip removed as Alwyn found in post#7 that there was no point in just attaching it.

    I don't remember as I didn't keep the script. MCDegrainSharp, SMdegrain, TemporalDegrain(2) ...? added to the end of the IVTC script.
    Main point was the correct (and less common) IVTC, the rest was some quick shot as an example for the text.

    I've said it before: there's no point in putting up modified videos if you don't tell us how you made them.

    I gave you the answer as good as possible in post#6. As I said it before, you are not a moderator. Instead of telling others what to do why not supply a better example/proposal? Taking your comment serious I will remove the modified clip. No point, no problem.
