No transitions or fades on the audio.
I determined the cause of the problem is audio plugins. For some reason, certain plugins, during export, don’t start working right away, so the first second or so of the clip is unprocessed or improperly processed, even though they work fine during editing. I’m still investigating the situations in which it may occur.
I’m not sure about the audio-only export, because that’s a lot more than just a delay.

You’re going to want to look under Modify -> Retime -> Video Quality (or Video Quality under the retime shortcut button, which is just to the left of the Effects button) and then select either Frame Blending or Optical Flow. FB is simpler and much faster, generally looks either okay or good, and works for most footage. OF only works for some footage, and depending on whether or not it works or not, it can either look outstanding or horrible. 😀 You can find information on both techniques; the best thing is to experiment with them.
Since you’re dealing with slowed down footage, both options should be applicable.

I’d call them “semi-destructive” in that you’re modifying the original clip using non-destructive methods, but modifying the original clip nonetheless. The better usage pattern would probably be to leave the original clips intact and create a new compound clip for sequences you want to reuse. There are various techniques for working with compound clips that I won’t bother to explain here (I believe it was in the MacBreak Studio podcast if you want to take a look at it) that allow you to reuse the clips and make changes that propagate to all projects you use the clip in, but also allow you to lock in changes to a specific project so it remains as is without changing. It’s kind of complicated and hard to explain without examples.
I would personally limit modifications to event clips to things that are correctional in nature, like configuring audio channels, removing noise, fixing color casts, etc. – but of course there are a lot of methods. Do what works. 🙂

1. Repair permissions (using Disk Utility). Restart, then see if it helps.
2. Delete caches. Easiest way is to go to ~/Library/ (in Finder, go to your home directory, then select Go -> Go To Folder and then type Library) and delete the com.apple.FinalCut folder, then restart. If that doesn’t work, try deleting the entire Caches folder. This can also solve all sorts of weird issues in other programs and the system itself.
3. If that still doesn’t work, try creating a new user account and launching FCPX from that account. If it works, then it’s preferences or something else user related. At that point you could try making backups of FCPX preferences, then deleting them and seeing if it fixes the problem.

Have you tried turning it off and on again?

Select clips you want to change (Command or Shift click to select multiple), type Ctrl+D, enter a duration, enter.

Mainly because I haven’t done it in Motion yet. I know of at least one way to do it (a very manual process, not suited for publishing as an effect) and another way (which could be published as an effect, but could have artifacts if the speed multiplier wasn’t a multiple of the motion blur step count).
- Method 1: Speed up the clip, duplicate it manually and shift each by 1 frame, composite the layers. This would also allow for interesting effects (create more copies for a “trail” effect, less for less of a blurring factor). Publishing this would be tricky though.
- Method 2: Speed up the clip, use motion blur to interpolate. This should result in multiple samples but could also result in artifacts (discrete samples from an unequally discretized set of frames).
- Method 3: I came up with this one while typing the previous descriptions. Basically it involves using particles of the movie, with the number published as a parameter. Opacity would also be published; this could actually be exploited for a sort of multisample brightening for night timelapses. It’s more manual than simple frame blending but would give a lot of control over the final result.
I think I’m going to experiment with Method 3 a little bit, that seems like the most viable option.

I do get frame blending as an option but it doesn’t do anything. It only applies to clips slowed down, not sped up. If I speed it up by 8x, for example, it only shows 1 per every 8 frames, not groups of 8 frames blended together.

To clarify – take the clip you created (the one that contains your edits) and put it in your project timeline. Then, break that clip apart. It’ll expand the components in place and you’ll end up with the individual clips placed within your project timeline.
Before you do that, make sure to trim the clip ends out to their limits; I’m not sure what happens if you break it apart before doing that. It might cut some of it off.
So together in sequence:
1. Go to project timeline
2. Add clip to timeline (E)
3. Select clip in timeline (don’t open it, just select it)
4. Drag ends left and right as far as they’ll go
5. Clip -> Break Apart Clip Items -
Select the combined clip (called a “Compound Clip”) in the timeline, then select “Clips” -> “Break Apart Clip Items” from the menubar. You should be good to go from there.
EDIT: Actually, since you “edited” an event clip instead of creating a new Compound Clip, I’m not sure Compound Clip is exactly the right term here, but I did test it and it does in fact break apart like a normal compound clip. What you might want to do (just to clean up) is then open the clip you created in the timeline again and delete all the extra changes, which will recover the original event clip. Be careful that you’re working in the right area of course. Backups are never a bad thing. 🙂
