Working with different framerates…I’m stuck
Hi,
I’m currently editing an actor’s showreel for a friend. One of the clips (from my own short) is in 1920×1080 25p. All the other clips (which have been ripped from various sources) are all in 1440×900 captured in 60p but the originals are standard 24/35p.
I’ve tried so many things to get this to work. Either making a sequence based on the 60p clips, which results in the 25p being choppy once rendered or vice versa when creating the sequence based on the 60p clips.
it looks like this after output (the first sequence is from the 25p source, and plays fine, then comes the 60p stuff:
pass: test
I export to mp4, h264 25p (or 60p)
I’ve also resized the 1080 clip to 900 to match, if that was the problem, but it didn’t help.
Any help is much appreciated!
Kind Regards,
Johan

Mixing framesizes is usually not a problem.
Mixing framerate is. I have never got good results with dropping 24, 30 or 60 fps in a 25p timeline.

OK.. So the only solution is to get the other clips in the correct framerate? What if some are 24 and some 25? I guess, that’s such a small difference that I’ll just be able to re-time it to the other framerate in After Effects and then just Pitch Shift the audio.

Do you have any requirements for your master?
If not I would choose the smallest frame rate you’ve got (24fps) and conform everything to that. It is easier (from a software point of view) to take out information than to recreate some frames by interpolation that do not exist. In After Effects I would use ReVision FX Twixtor to get the best result.

Hi David,
Many thanks. Do you have any link to a guide/tutorial on how to get the best results?

Actually… Since the original source on the 60p material is 24p, there are a lot of double frames here and there. So if there’s a simple way to remove them, that would be great.. Perhaps that’s what Twixtor can do? And then fix the audio…. hmm…

So, if I use twixtor.. How will I make it delete the “still” frames not used?
The big problem here is, once again, that I every other frame is not progressing the clip and every fourth frame I get two still frames in a row… 🙁
Kind Regards,

I am guessing you are talking about 60i (interlaced footage) and not progressive? and it sounds like your original footage was shot 24p and some pulldown was added (either in camera or post depending of your footage history!)
So first thing first, you need to remove your pulldown: I usually use After Effects, and in your interpret footage it lets you interpret the kind of pulldown you have. Make sure you established the right pattern by playing one frame at a time in your source window and that each frame is unique.
HTH,

Hi David. Thanks for the reply. Nope, it is 60p. The software the guy used to rip the video with was for some reason capturing at 60p..

Just finished a long project with mixed frame rates and it was very painful! After long hours with Adobe tech support, here is what I found. You CAN NOT mix frame rates on the timeline and expect them to conform, even if you try and modify prior to dropping on timeline. You first have to use encoder to change the frame rate and output a new clip. Then import to project and drop into the timeline. Then and only then will everything play well together and output correctly.

Ok Russel. In this case it seems extremely hard as it is 24/25p footage ripped in 60p…
Kind Regards,
Johan
