Logic Pro X is stuttering video

1) In Finder, duplicate the video file provided by the editor

2) Open it in Quicktime 7 (you'll have to find this on the internet or copy it over from an old OSX installation if you don't already have it)

3) Use the Movie Properties inspector (Cmd-J) to remove the audio track

4) Save as a new file with "(No Audio)" suffix

5) Pull that into the Logic Pro X project - Tada

Thank you! It's really to work!!

Hi guys, I just figured out what is the cause for bad playback. If the framerate of the project isn't the same as video's than the video playback is bad. Just go to File>Project settings>Synchronization... and there change the fps to the right one, that matches the video's.

Don't worry if you don't know your video fps. You can always experiment in logic as there are not many in options and most common are 24, 25, 29,97 and 30. Or you can find programs that can tell you fps of video file.

I hope this works as it worked for me.

An easy way to figure out the framerate of your video is :

open video in quicktime, press Apple I (Information) there you will get your framerate info 😮!

The problem we have been talking about was serious stuff that apple fixed with their latest update!

Brand new 12 core Mac Pro, 32 GB RAM, dual FireProD500 video cards, 500 GB boot drive, (running session from boot drive), two monitors connected via thunderbolt to mini-display port to dual port DVI and one TV connected via HDMI, still getting video lag. None of the suggestions here worked but the problem seems specific to certain projects and/or videos (converted to ProRes with no audio). Sync setting match frame rate.

Not playing video on TV seems to help.

This just totally s*cks. What's wrong with Apple?

So far I have found that the only thing that fixes this problem is to re-import the project, but not the project settings. So it's clearly some kind of project corruption at work.

There's no way I can recommend using a beta OS to my production users. I hope 10.9.3 release fixes this.

Just did a very quick test. Tried mp4 and Quicktime movies of previous film projects in Logic X. They were unworkable before with glitches/lag. Definitely the best it's been now after 10.0.7 update. Certainly workable.No noticable glitches/lag - then tried A/B test with Logic 9 using same films - Logic 9 playback still seems smoother to me with no delay in playback moving to different parts of film. Interested to hear other people's experiences with update.

I just finished transitioning my template back in 9 this morning. It's working great. The midi scrub thing is definitely nice to have back! I'm going to score this whole series in 9!

Definitely a difference in applications though.. Logic 9 would run your video in it's original format without problems, right?

Yes but this solves the problem and allows you to work with all the new features in Logic X. However, the problem with the snapping to scene cuts (frames) still remains.

Tried this. Didn't work for me - the 422ProRez file was less stuttery but still unworkable. Still working in Logic 9.

Same here. I score for TV. No matter was QT file format, it's randomly stuttering, and very hard to lock too. I've used logic since 1993, and they usually fix these type of issues much quicker.

send feedback done..

hope a lot of you do the same..

enjoy !

Done already

Thank you. Feedback sent - let's hope they fix these so we can actually use X.

Same here, exactly Chris! Crashes a lot, BUT at least it saves 🙂
