Hi Guys

Feeling proud of myself, had to share this because it was causing me no end of frustration

Every time I edited my Spark footage with iMovie, any panning or motion shots would be jittery.  Really ruined the smooth cinematic motion of the video.  

The problem seems to be that iMovie cannot correctly identify what frame rate the DJI Video image is using.  

So to fix the issue, you need to use import a 30fps 1080p first to set the correct "mode".  After that, you proceed as normal.

Here is a link to the sample image I downloaded.

http://all-free-download.com/free-footage/merlot_grape_145.html

Process as follows:

1) Create a new project
2) Import the 30fps sample file first.  (MUST BE FIRST)3) Add the sample to the start of the timeline
3) Then import your Spark video files.
4) Add your spark video to your timeline, but trim a few seconds off from the beginning.  *** THIS IS IMPORTANT.  Do not just drag the whole clip into your timeline ***
5) You can delete the 30fps Sample file now

VOILA ! Fixed.

Here is a link to a test I did after applying this fix.



Hope this helps !!

Full Disclosure...I didn't discover this fix myself, I worked it out based on various other fixes I googled

Very interesting and great tip.
They should make this a sticky post I guess
Amazing how simple a solution for something this annoying can be.
Thanks a lot.

The iMovie export will be in 30fps with that procedure.  Not a problem for me, as I have switched all my cameras to 30fps anyway.  I don't mind that it looks overly real.  My use is simple.  

Some people want iMovie exported to 24 or 25fps so they can look like George Lucas on his best artistic days.

i don't know.  There is no FPS setting in imovie either (that I could find).  To test it you'd need to get the 30fps 1080p file on your ipad first.   

I would be surprised if this worked, but it's worth trying

As far as I can tell, the frame rate is set by the first clip in the video.  So if you start with a 24fps clip you get a 24fps clip out even with 30fps Spark clips or 25fps European clips inserted in the middle or end.  I haven't found a manual setting for it.

Yes, I think that's correct for a Mac, but not sure if that's true for the iPad.

I also think it's set by the first video you import, not the first video you add to your timeline.

I might do some more testing tonight to confirm

I just trim a section off the clip before adding to the timeline, does the same thing, but less steps involved. No need to add in extra files.
This has been a common fix on the forum for quite a while now.

I read about that and tried it, but it didn’t work.  Tried it many times of times, including last night.   Not sure why.

My workflow is always to add only a portion of the clip. I never add the whole clip to the timeline

Another mate of mine had the same issue and tried the trim fix and it didn’t work for him either

The process I added above seems to work every time.   Can’t explain why

That’s odd that it doesn’t work. That’s my workflow for iMovie now. Been great so far. I guess what ever works gives the best results.

I did some more testing and found that for me, on my mac, I need to import the 30fps sample file AS WELL AS trimming the first few seconds of the cliip.  Doing just one of them isn't always enough

I've updated the original instructions accordingly.

Ah ok. That’s interesting. I normally just import each clip. Trim them down a touch then drag them onto the timeline.

Out of interest, have you tried skipping the 30fps file ?

Yes.  Many many times.  Didn’t work.  Friend also tried it, and didn’t work.

Unusual how it works for some and not others.

A liitle bit tricky. Adobe Premiere Pro goes more easily this way.

Yes, this is particular to iMovie I think.  But there is a big difference to cost of iMovie vs Adobe Premiere Pro.

This way one can try DaVinci Resolve. It's for free.

I have heard good things about Davinci Resolve.  But i’m happy with iMovie.  There are some extra steps, but it only takes a few seconds.   One day I may upgrade to Premiere, but don’t see the need for now.
