The only way to do sub-frame adjustments is within the audio, you can’t do it with the video in the timeline.

I’ve done this in the past with really nice results by simply taking portions of the longer clip and fading them into each other. You can try this in addition to speeding it up.

Depends also what you’re shooting. I was shooting a Seattle skyline sunset, so if it’s sped up a reasonable amount, and then you so some fades, you get a really nice effect. You just do a succession of several fades maybe every 5-10 minutes of your footage for say a sunset, and it advances quickly and you get a really cool effect. Experiment with layering several really really long fades over each other too, you get the lights coming on and such smoothly, etc. If you had say traffic or people walking around, it might not quite get you the time-lapse type effect you’re looking for a-la Koyaanisqatsi.

But that’s what I did when I didn’t know what I was doing, and it looked great! Not that I know what I’m doing now… 😉

Your video is playing out at 60hz to your display.

This has nothing to do with audio. hz =/= khz.

What is your question?

I was just searching for the answer to this question myself and discovered that the Strobe filter does a pretty good job of basically just making your video a slow frame-rate. If you actually want to make it realistically like stop-motion, then that would take more effort. I was just going for a look of basically a series of still frames, and didn’t want to make them all manually. the strobe filter does exactly that, simple!

Hope that helps someone else. 🙂

You guys are missing the Blink Filter which does this auromatically for you. If you just stack one clip on top of the other, then set the blink as fast as you want, it will reveal the underlying clip, rather than black, and you’ll get the effect in the YouTube video the OP linked to without having to spend all the time manually cutting frame-by-frame which is silly.

Here is a detailed guide:

Well, the damage is that it’s clipped.

If the underlying audio was not clipped, then that’s no good.

Hence the need for compression to limit the peaks.

This isn’t a “feature” it’s inherent to any digital audio. You simply cannot go beyond a certain point. Same with digital video. You simply can’t go above 254/255. Anything above that is brick-wall clipped off, inherently.

It’s a compressor. That’s exactly what it’s for. You just set the settings how you want it, and if you just want to prevent peaks from clipping, then you set it to do that.

If you don’t want it to compress the audio range, then you don’t set it that way.

It’s just an audio compressor, it only does what you tell it do to. They’re all pretty much the same thing, whether in FCP, in STP, in Pro Tools, in hardware, etc.

Multiple tools to accomplish this in FCP:

If you set a high threshold, a fast attack and release, and a strong ratio, that will kill all your peaks with any compressor tool, including in FCP.

Or you can take it all into STP if you feel like doing that:

I just use iTunes for this.

As seen above, lots of ways to skin the cat. If skinless cat is your thing.

Have you just output a standalone quicktime file using the same settings as your project, which appears to be ProRes 422?

If that doesn’t work, then perhaps you have some corrupted media or missing source files?

Try exporting a smaller portion, or half of the project and see if you can isolate what’s messed up.

If you can get a standalone .mov file in ProRes, then you just take that into compressor and compress to whatever you need, here that would be h.264.

There are compressor & limiter filters already in FCP. They’re in the audio filter folder.

Just drop those onto the clips you need. If you need to do your whole sequence, you can highlight all the audio clips or select all the clips in the tracks you need, and then drop it onto that and it’ll apply to all of them like any other filter.

Is this not working for you or something?
