PAL Progressive to FILM

[~Revolution~]

I have a PAL Progressive (25 fps) source that I want to bring back to 24.000 fps or TRUE FILM Rate. I am aware that there may be some shortcut methods of doing this but I want the SLOWEST and most QUALITY yielding method that exists. I seriously am willing to wait for weeks for the encode to carry out because I want to make the best copy possible of this disc for myself. If someone experienced in doing this can help me out then that would be great. I basically want to know how to make the script for the conversion process and how to correctly convert the audio with maximum quality yield. Once again I'm willing to execute the slowest script possible for this to work out perfectly.

Thanks in advance.

Are you using DGIndex??
you can setting it.

I am using DGIndex but how will that help in the conversion process? If the DVD is a discrete 25 frames/s progressive then I would think there needs to be some manual conversion done. But I'm still sort of a n00b so I may be saying something totally wrong.

From the DGIndex site:

"Force Film - This option is intended for the special case of film content encoded at 23.976 fps but pulled down for display at 29.97 fps, i.e., 3:2 pulldown. This option will restore the 23.976 fps film rate while keeping audio and video in sync throughout the clip. This option works by ignoring pulldown flags and inserting/removing frames to maintain a constant and sync'ed output stream. Do not use this option on non-3:2 pulled-down material, and, therefore, never use it on PAL or MPEG1. Also do not use this option on streams containing frame repeats. "

Also my main objective is to bring the video back to TRUE FILM RATE or 24.000 fps NOT 23.976. I want to bring it back to perfect film rate and the audio as well in the slowest and greatest quality output method.

Will the content cope with a 4% slowdown without being objectionable. i.e. Music and singing will sound dull while sport or people talking will probably be unnoticeable.

So trial 1:-...
AR=AudioRate()
AssumeFPS(24, 1, True)
ResampleAudio(AR) # or perhaps SSRC(AR)
...
Depending on the content you may be able to just use ChangeFPS(24, 1), this will drop 1 frame in 25, which will spoil any smooth motion if there is any.

If you must keep the time rate the same, then perhaps MVTools might be a possibility. Again the process is content sensitive as with any tricky motion you may get artefacts.

Sounds like the source really was originally 24fps, so the 4% slowdown may not be an issue:

assumefps(24,sync_audio=true)

And that's all there is to restoring the frame rate. As for anything else, what's your target format/usage? You might (I don't know if this is possible) be able to keep the original file and alter it's framerate directly to 24fps, though it would no longer be DVD compatible.

It should be noted, though, that some films are released in PAL at 25fps but with no pitch change on the audio (Stardust was one such DVD).

Also assuming the intended output is DVD, you just run the M2V through DGPulldown set for 24->29.97.

And I don't know where the talk of weeks of encoding comes from when, as mentioned, a simple AssumeFPS(24) will do the trick. And why 24fps and not 23.976fps also baffles me, since no one will ever be able to tell the difference.

You could, if you didn't care about the quality - pulldown is evil! I assumed the output wasn't DVD, given the "24 fps" and "high quality" requirements.

I've cut a sample for you guys to look at and see what needs to be done. As far as the 23.976 and 24.00 fps difference, its basically a mental thing I have but also because I thought that a proper PAL source is sped up from a 24 fps flim and that 23.976 is the NTSC slowdown. So wouldn't reaching 24.000 fps be easier? And as of now I don't want to make this into a dvd. Just a nice x264 mkv rip at 24 fps.

Why are you talking about "progressive PAL"? That sample is interlaced PAL, and it contains the usual fieldblended stuff. That cries for Srestore, coming out at 23.976 NTSC/FILM anyway ...

:scared: this is interlaced. dammit I didn't see it before. most of my REM discs are progressive. Well I guess I'm going to have to work with interlaced then. So I guess its the usual


interp=nnedi2(-2)
yadifmod(mode=1,order=1,edeint=interp)
srestore()


for this source?
