workflow for editing with 25/50/30 fps
hello
I’m editing a videoclip on adope premiere pro cs4, we shot with a canon D500 and a lumix gh3.
unfortunately the sizes and frame rates differ, we have:– 1920×1080 / 25 fps
– 1280×720 / 50 fps
– 1280×720 / 30 fps(used a fisheye-lense, converted raw files to prores)
now I’m not sure what the ideal workflow would be, what timeline settings I should use and if I should work with “interpreting” videomaterial. figured I could do it on a 30 fps time in full HD, but then it would end up being NTSC-standart and I’m in europe. would I lose a lot of quality having to converting the final export into PAL-standart, and can premiere do that? or would compressor do a better job there…?I’m working on premiere for compability reasons but I would also have the option to work on FCP 7 or X.
thank you for any ideas and inputs!

If by “Full HD” you mean 1080p, I would avoid that as your 720p footage up-ressed will look terrible. If your final delivery is PAL, I would edit in 720p then just output the video to PAL standard upon final export. This can be done out of Premiere.
As far as your frame rate goes, I much prefer the look of 24 (or 25) compared to 30, but in this case I would probably go with 30 as that’s less conforming for the 50fps material. If you create a 30fps sequence and just drop the 50fps footage in there, I believe premiere will just drop one out of every few frames in order to make it fit. Then you can conform the 25 footage to 30, which will result in a slight pitch shift in the audio, which can be easily compensated with Premiere’s pitch shifter. I would make sure to keep all of the 25fps audio on it’s own track throughout the sequence, then you can just apply the pitch shifter to the audio track via the audio mixer.
I’m sure you’ve figured this out by this point, but it’s wise to think about your settings before you shoot, so that all your footage has the same look and you have much less technical problems in post.

dear JP, thanks a lot for the answer!
you’re absolutely right we should have thought about the settings, I’m usually in post but I rarely shoot… will definately learn from my mistakes.:) so I created a 30p sequence in 1280×720, onto which I drop my 30fps-material and get a yellow line (don’t know why, maybe because there’s an alpha-channel). with any other clips I put on there (25, 50) I get a red line. I can play it but it slows everything down a lot. is there any way to avoid that?
and what do you mean by conform my 25 footage into 30, do you mean with the “interpret”-option? actually, the stuff shot in 30 fps is not the most important, we’ll try to keep it short and use more of the 25 / 50 stuff. so would it maybe be wiser to use a 25 timeline after all? does it make a difference if the 50-stuff has to be conformed anyway? since it’s for a videoclip we don’t need the sound…
thanks again!

Yes I did mean the interpret option. Different names in different software haha. Although if your 25fps footage plays back fine in the 30fps sequence without conforming, you might consider just skipping the conforming process. I would duplicate a clip, and conform one to 30fps, leave the other as is, drop them both in your sequence, and see if you like one more than the other.
As far as the yellow/red bars go, that just means the sequence needs to be rendered. Go up to sequence > render in to out

hey, phew, all that conforming stuff is confusing. I exported a 30 fps sequence in current settings, once with the original 25 clips and once with the interpreted-as-30 25 clips. can’t really see a difference. but since I’m planning to do the final export in 25 fps, I’m guessing I’ll just skip the interpreting-as-30 for my 25-material. so:
– editing 25, 30 and 50 fps material on a 30 fps timeline (in 720p)
– without interpreting / conforming
– exporting in 25 fps, 720p…but does that mean everything will be slower on the final export, including the song I put over it? do I have to do that audiopitching thing you were talking about, even if the sound is not that of the clips? basically, if I convert the final export from NTSC (30) to PAL (25), will that slow down everything and will I notice the difference? and to avoid that, would it make sense to edit on a 25 fps timeline?
I guess it’s choice between dealing with more rendering during the editing (if i work on a 25 timeline) or ending up with a final export that is slower than the one on my timeline (30).
I know the lines mean rendering, but since I work on a laptop I wanna avoid this slowing down the process…
thanks again!

Thanks for sharing all that info ……….I made the exact same mistake …of filming at 29fps when I actually wanted to use 25fps ……..I will hopefully make sure future projects are in my preferred 25fps .
Thanks
