60p to 24p in FCPX

Conforming 60p to 24p for a slow motion effect with Final Cut Pro X (updated)

This used to be easy with previous versions of Final Cut Studio and the bundled Cinema Tools. How do you conform your footage if you don't have Cinema Tools?

Retime > Conform

It's now even easier than before. Drop your 60p footage into your 24p (23.976) timeline. Select the clip and choose Conform from the Retiming Menu.

Your footage is automatically conformed to fit your 24p timeline, changing the speed to exactly 40% (the difference of speed spreading 60 frames per second across 24 frames).

This should save some people a lot of time, especially when conforming 60p footage shot on a DSLR.

What I used:

  • Canon 7D
  • Canon EF-s 17-55 f/2.8 IS
  • Redrock Micro Field Bundle

Update: In Final Cut Pro 10.1, Apple has changed the wording from Conform to Automatic Speed. It functions exactly the same.

Wow, awesome tip. Thanks for sharing. FCPX does have some tricks up its sleeve.

Cool Dave- didn't know "conform" was in that pulldown. You should try the same clip at 10% with optical flow turned on- love to see the results.

Apparently this tool also affects the color grading of the footage.

Awesome if you need slow motion. However if you conform it in Cinema tools, it actually conforms the clip to 24 frames; meaning if you speed it back up it should still have the look of 24 frames. If you do this FCP X, that does NOT work. If you conform with Cinema Tools and edit in FCP 7, you choose slow or regular and still have the same smooth look. Since Cinema Tools is no longer available, it looks like FCP X still has another bug to work out.

Great Tip!
I'm having problems going even further, to let's say 10 percent. When using optical flow the video gets jittery. Do you know why that might be ?

10% is really slow. I know even Twixtor has problems going down that much. The image would look better if 10% was applied to an i-frame codec instead of the h.264. I know this scene didn't look good at all with optical flow. Parts of his arm would blend into the bricks.

Thanks for the helpful tutorial. Just wondering what happens if you try to retime the clip after conforming? For example, I film in both 30p and 60p, and would like to drop all clips into a 30p project. Clearly the conforming works great to generating smooth slo-mo with 60p clips, in my example reducing the speed to 50%, but can you then retime clips after conforming them? I'd like to get the most out of my 60p clips with some ramped slo-mo down to speeds slower than 50%.

There are 2 things that can happen. CONFORM spreads a clips frames out to match a slower timeline/storyline frame rate. That's why the 60 frames per second spread out over a 24 frames per second timeline creates a 2.5X slower clip. Conforming also messes up your audio (or slows it down, but with pitch correction).

If you just want to drop a clip in your storyline and change the speed, use the retiming and select optical flow for quality.

Thanks for you response. Will a 60p clip dropped into a 30p timeline keep all 60 frames when re-timed and exported? I was under the impression that one had to conform to match the timeline before re-timing or else frames would be dropped.

Hey, it doesn't work for me. I put a 50p clip into a 24p timeline, conform the speed, move the retiming down to 25% and it still jerks just the same as it does when I don't conform the speed prior to retiming. I have no idea what I might be doing wrong. Any suggestions would be awesome as this has been bugging me for ages!

This process does work for me. Except all the other footage i want to keep looks choppy. Only the slo mo looks smooth and the regular speed looks choppy.

This is great in the timeline but I wonder if it can be done in the viewer. I'd like to have the clips retimed for then I am logging and selecting favorites. Is this do-able?

The only way in FCPX to conform so far is to use the timeline as the "conform to" rate if you have faster frame footage to slow down. If you drop 60p into a 24p timeline, it will look a bit choppy since it's dropping frames. If you render the section (or wait for it to), it should look a bit better.

I have a problem. When I go around %33 percent somtimes up to 37% to ramp slow mo a clip, my audio cuts off in that section. I've used another computer and my slow mo has gotten all the way down to 20 and the audio is still there. what's wrong?

When you put at 60fps clip in a 24fps timeline, the clips is not ataamuticolly slowed down BEFORE retiming in FCPX?? does FCPX allow the frame rate converting if so how is it done? do you just drop the 60fps clip in the 24fps timeline..

FCPX doesn't have an option (at the moment) to conform clips outside of the timeline. Cinema Tools lets you do this, but comes with earlier Final Cut Pro bundles. The reason it doesn't to it automatically is because of their "any format" timeline. When you drag the first clip in, it asks if you want to change your timeline to match it. Then, every other clip coming in will play correctly based on what type of clip it is, so you can mix various frame rates together.

This solves an edit where almost everything is 30p but some things provided are 60i or 23.976 and they cut and intermix without any playback issues.

Hi Dave,

I just upgraded to FCPX 10.0.8. When I drop my 60fps clip onto my 24fps timeline, it plays really choppy. Before, it would play just fine as a normal 60fps clip alongside 24fps clips and I could retime it as normal for slo-mo.

Now, once I drop it in, it's already choppy and this is after it has automatically rendered, and without me making any retiming adjustments.

Please advise.

Hi Dave,

I just upgraded to the most recent version of FCPX and my 60fps footage is playing choppy in my 24fps timeline. Before I upgraded, it played normally, and I could retime.

Now, it's choppy right off the bat and I don't know what to do.

Please advise.

Hi Josh, the new 10.1 update just released today. While that may not solve your issue entirely, I can only guess a few things that could be the problem. Your machine might be trying to play 60fps in a 60fps timeline. If you want your 60fps clip to play at 24fps, you need to create a new project with a custom framerate (23.976) and drag your clip(s) in. Make sure you don't let Final Cut adjust the project based on the first clip you ad to it. THEN you can retime (conform) your clip.

If you have a 60fps clip in a 60fps timeline, your machine might be choking trying to play it back.

After changing the clip from 60 to 24, can I change it back? I forgot that I needed the audio and now it's distorted by the slow motion. Does this make sense?

This is all cool and stuff, but can fcpx do a batch conform of 60p footage to 24p. Because doing clip by clip takes a stupid long time. I there an option for this?

24. David wrote:

There isn't a batch speed change in the clip browser, but you can select multiple clips in the timeline and apply speed changes all at once.

One think you could try is to setup a 24p timeline and drag all of your 60p clips in, select all the clips and conform. Then you can use that timeline as a source to copy/paste clips into other timelines. Still, it would be nice to control conforming in the browser vs the timeline.
