Just as the headline says. I shot a wedding and accidently forgot to change the frame rate (Sony AVCHD, if it matters). I need the clip to get to 24fps without using slow motion (I need it to look real time) and I need the audio from the clip as well. So, clearly going to Interpret Footage>Frame Rate won't work because the audio and film slow down. Even unganging it as instructed by Adobe in the manual doesn't work quite right. Any help would be greatly appreciated!
You simply create the sequence the way you want it to be and drop your footage on it. When asked if you want to change the sequence settings to match the video, tell it "no".
The video will play at the normal speed.
Only if you interpret the footage do you get slow motion. Otherwise the 60fps footage plays back at 24fps by dropping 60% of the frames. Which is not the same as recording it at 24fps because the shutter speed was a lot faster, but it should still look fine.
Drop the footage into the project, then interpret the 60 fps to 24 fps. Drag footage into timeline. Then right click clip in timeline and select replace with after effects composition. Then use timewarp effect to speed the footage back up to normal speed, I believe 225% should do the trick. Most Importantly make sure to select enable motion blur. I usually select the manual option under the shutter control and set the shutter angle to 180 at 5 samples.
In most situations this fixes the shutter speed difference when adapting frame rates.
A great workaround, though I found I had to convert everything in AE instead of being able to link out the footage from Premiere. Either way, gives perfectly smooth footage with lovely motion blur.
thank you for this explanation. I am still learning After Effects and can't find any info online on how to speed up footage with the TimeWarp effect. Looking at the effects panel, I only see an option to slow it down (the scale is -100 to +100 with 100 apparently being the original speed i imported it at. You mentioned speeding it up by 225%... could you help me find where to do that? Thank you!
Do you render it after? I'm looking at 8 hours of rendering right now O.O
I know I am way late to this thread BUT I am here because I was trying to figure out the same thing but through Premiere Pro. For anyone here looking for an answer, I figured out a way to do it just in Premiere Pro (Not AE).
So I started with a timeline of 60fps, modified all of my footage to 24fps to make sure I have all of the slow-mo I want, then I followed these steps to get an authentic 24fps look for particular clips in real-time:
-Start a new sequence just to use for conversions but make the sequence a 24fps timeline
-Drop clip in the 60fps timeline
-Raise speed to 225%
-Drag that clip to the 24fps timeline
-Nest the clip into a new sequence (that way it nests the motion blur from the 24fps timeline)
-Drag that nested clip back onto the original 60fps timeline with the rest of your project
I hope this helps anyone looking for that answer!
If I were to put my 60fps video into the 24fps timeline, and export that video. Would the video essentially have converted into 24fps, but still playback at a regular speed? I am trying to rotoscope over a video, and need it to be in 24fps instead of 60fps so that I don't have to animated 60 frames for one second lol. Thank you!
@afkvisuals Not a perfect solution because the new footage will appear choppy.
so then what is the solution? I have a music video with everything filmed in 60fps. some footage I wanted to slow down. and some footage I wanted to keep as normal. I'm planning on exporting it as 24fps for the cinematic look. so I have the sequence settings set at 24, and iv just dropped all my 60fps footage onto the timeline. I assumed premier pro would do the work
Did you get an answer to this?
I think you don't even need to make a new sequence, if you just edit your current sequence settings and change it to 24fps it does it automatically and my footage didn't come out choppy. I also needed to scale my footage down to give it the cinematic feel, and to reduce the number of frames I have to edit for animating and After Effects comping for a music video. I created the After Effects composition and it then only had 24 frames instead of 60.
