I never need to convert from 24 to 25 but since the hbr in gh2 is not best so far I did one test which seems to work ok let me no what wrong with this if im wrong. Im changing now from Fcp to Premiere. If I open new sequance avchd 1080p25 and put 24fps mts file with keeping origin 25p settings there is red line but clip stays origin length like 25p would do (no change modify and interpret to 25) edit and export to 25p. Red line probably make edit not easy but that looks like simple solution?

@meierhans if you confirm to 25 after edit everything get sync off

How do you conform 24->25p in Sony Vegas? This is the first time one of my customers wants a PAL DVD (it's true) and I have shot everything in 24p (23,976). What should I enter in the clips properties? Resampling off, I presume and then what: playback rate 1,041? What about undersample rate? This is very confusing :(

What i am going do in premiere pro: I just choose "interpret clip" and change the framerate from 23.976 to 25 i/s. That means I got then a clip accelerated to drop in the sequence. For sound I have to change pitch. I use the audio effect PitchShifter.

Hown many semi tone for correction?? lets see this: http://centpoursample.free.fr/sampling/sampling_conversions.html

My calculation is the following:

alpha=1.05946049

A=23.976/25

x is the number of semi tone to disminish the pitch of sound ofthe new frame accelerated (from 23.976 to 25).

We have : 1/(alpha^x) = A

that means : x=Ln(1/A)/Ln(alpha)

So : x=0.0419224/0.057759=0.724=0.724

I will choose in premiere pro (audio effect PitchShifter): -1 semi tone for Pitch and +28 cents (Fine Tune)

Tell me if I am correct. Thx.

Guess you wont use audio on 60p slomos, so just interprete them as 23.976 on import and they will act like "normal" clips - beside the lack of audio. From this point on you are dealing with a regular 23.976 timeline and can conform to Pal after export.

Guys, for the case somebody still wants to know which editing software can edit or render with pitch correction or without it: Magix editing software can do it.

@peaceonearth asked that nearly one year ago but somehow I missed it then.....

I live in PAL land and shoot 24p as well, and although I've succesfully delivered PAL DVDs in the past using Canopus ProCoder (which automatically speeds the footage up upon conversion) the problem with sound is it's not just 4% since we shoot at 23,976 fps, not exact 24p. What I used to do was export the sound from Premiere and load into the old Audition and then use Time & Stretch and copy the duration of the 25fps ProCoder exported WAV into the 23,976 Premiere exported track to get the exact same speed. It was convoluted, but that's what I used to do, and mainly because the quality you get in Audition doesn't compare to that of Premiere when stretching sound.

So, summing up, you should first finish and close the edit, then export the final audio, then export the video separately interpreted as 25p and get the duration of that "squeezed" audio to use it for changing the speed of the audio track in a dedicated audio application with the best possible quality OR you can export the video interpreted as 25p and speed the audio up in 4,170837504170838% (or 4,1709% which isn't as accurate but it's easy to remember and write) without changing the pitch.

In any case, use the best application and quality possible to change the speed of the audio track if you want to yield the best results (which I think is the case if you are indeed worried about the pitch, because otherwise most people won't really notice unless they're hearing their own voice or they have something to compare it to)

@sammy

You have several options, one is to render it from 23.976 to 25, and that's the worst one.

The best possible option/workflow would be to go back to editing, and interpret your video files as 25p in a new 25p project sequence. That will cause them to shorten. Correct your cuts for the new length of video files. Export as 25p and that's it.

You can also just speed everything up to 25p and change pitch of the audio later, but that tends to be tricky, and you need very good software to pull that out and to preserve the audio quality.

Crop is fine, just make sure that you export it as one of two pal possibilities, 720x576 4:3 or 16:9, and not in any other resolution/aspect ratio, that means, for example, if they broadcast PAL 4:3 you should have black bars exported in the picture, and outer resolution of your 2.35 image and black bars should be 720x576 with pixel aspect ratio for 4:3.

You are probably on the safe side with DVPAL in avi containter, but you might want to check that out with the TV station because of the size of dv compressed files, many of TV stations here where I'm at can live with some mpeg2 files that are more convenient to send and store. Eventual introduction of fields (interlace) should be done at the final export. Anyway it's stone age.

@sammy best ask your client about that. For your earlier question: I render often from 23.976 to 25p with Magix Pro X and it looks excellent.

@inqb8tr could you please explain how to interpret 24p footage into 25p?.. thank you! :)
