why are my exported files so big

Hello all

first post
sorry for Newbi question

i exported 90 secs of footage last night (shot at 1080 60fps)
it exported to usb as h264 @27 fps and came out as a 850mb file (almost a gig for 90 secs)

i wanted it at 60fps so the slowed down parts were smooth but i havnt figured out how to do that yet

i have a brand new mac pro so the laptop seems happy enough with the workload
my editing skills are very basic

i must be missing a step somewhere but why does my 90 secs amatuer hack alot footage export so large.

You most probly selected in the Share dialogue Master file - those are encoded in proRes, not meant for distribution.

Instead choose Apple Device, and in the next dialogue, choose Computer.
This generates a tiny mp4-file in superb quality ..

thankyou that is exactly what i was doing

i never clicked apple device as i wanted it to be for computer, but low and behold there is a selection for that on the second screen

cheers

Yep, well hidden, I think it was wizzard Ronny who told me the trick.

If you own Compressor, you can build a set with similiar scheme, finally having a 'mp4' option in FCPX share memu

BTW you can achieve the same thing with Master File->Settings->Computer. They both generate H.264 with a good quality bitrate but not excessively large. Yes if on either Apple Device or Master File you use Format: Video and Audio, then select Video codec: Apple ProRes 422, the resultant file will be quite large.

Just to note a little something: if you want smooth slowdowns, then shoot as 60fps and edit at 30fps.
This way if you slow to 50% your video has all the frames to be played. Making your project at 60fps will NOT help.

HappyFingers,
Couldn't tell if a hidden ? was how to slow down (Slo-Mo/Speed Ramp) some of your video.
Easy to do in FCPX.
Here is one of many tuts available… digitalcinemacafe.com/2014/01/11/tutoria...-10-1-speed-ramping/
You can also apply speed changes to whole clips.
Hope this helps, Greg

Actually, shoot at 60fps, edit in a 24fps Timeline, about 40% actual in-camera frame slow motion. Then slow down more from there with Optical Flow. Look for samples on this forum from my friend Mickey Gaidos, he does this with great success.

ok thanks guys watched the video and that helped i found the video quality section

rendering now see what it looks like when its done

cheers

very helpful forum :woohoo:
