[HELP] Advice requested to convert 25 fps to 23.976

[Oldermediaformats]

Alright, getting this all figured out. Would you recommend doing a speed change for the audio first and then making the speed change to my video afterward? I read your reply in another thread to a poster's query that any changes to the audio should be done separately, but I'm wondering if I should prioritize the order of operations?

No clue what thread you are referring to, bug applying them in the same job should be fine.

I want to revisit this thread because I am after something very similar that DannyHicks discussed with Selur in this thread.

I have a PAL disc of a movie that was shot on 35 mm with a native frame rate of about 23.976. (It was properly transferred to 25 fps from its master. It's not one of those improper NTSC to PAL conversions where you can immediately notice ghosting and combing artifacts.) It was scanned beginning with the top field first. The encode is interlaced. So I'm specifying TFF for scan type and using QTGMC as my deinterlacer in VS.

Like DannyHicks, I not only want to perform speed changes with both video and audio (so they sync to 23.976), but also want to "expand" each frame so the total runtime is longer. So, this movie runs 94 min. 44 sec. on the PAL DVD. I want to elongate it so it runs a total of about 98 min. 52 sec. after executing all the conversions. Because that's the approx runtime for 29.97 and 24 fps.

I have MKVToolNix and use it fairly often so if it would be easier to do a few of the preliminary conversions with the app before importing my file into Hybrid for any additional speed changes, I can start there.

Thanks!

change speed, for audio&video, both need reencoding (video only because of the deinterlacing)
(do not bob deinterlace, or use sRestore/DeblendS9/RIFE instead of change speed)
