Advice required:
I shot quite some 4K footage with my Pana GH 4 (4K/100M/25p) and trying now to edit with FCP X. Pans and object movements are "stuttering" on my iMac (27", 2,8 GHz Intel Core i7, 12 GB 1067 MHz DDR3, ATI Radeon HD 4850 512 MB) and I get the message "4K footage processing on this computer not advisable as you may encounter performance problems".
Earlier HD footage editing was without any problems.
Can anybody give me workflow hints how to keep the 4k "masters" and res it down to HD for smooth editing & output with the above configuration?
Advice much appreciated.
You have a lot of options.
First is to convert all of your footage to prores in either 4k to 2k. (there are a number of convertors for this that are inexpensive.)
Second if your editing heavy 4k on a bone stock apple, go into the preferences and lower the resolution settings and work the files at lower resolution.
(remember even in 64 bit fcp X there is constant rendering going on the the background so the higher the playback setting the more strain on the computer and graphic card. In other words fcpx is constantly converting your h264 footage to prores behind the scenes, hence your warning).
Once your edit is finished, reset to high quality, 100% resolution, 10bit for output.
I mainly use fcp 7 though the process is close to the same, but if you want answers to this Larry Jordan's site is the place to ask.
IMO
