Playing around with my new Phantom 3 pro this morning taking some great shots of a vine yard on a beautiful sunny day. The problem I have is that when I record in 4k
It turns out pretty grainy and I have some lines across the screen, pretty disappointed as I thought 4k was the bomb !! Also when playing back video it's very stuttery, been scratching
my head on this for a while.
Any advice on camera settings would be appreciated
Yes. post a clip. As for the stuttering problem, that's almost certainly because your playback device can't handle 4k video -or- you don't have an appropriate codec installed.
Ok thanks guys will try and post the video on here, I'm currently using a 2013 iMac top of the range with ei captain. So this would be why it is stuttering my iMac can't handle 4k ?
Can't say about your iMac, as I am not an Apple person, but it is not uncommon for many computers to be unable to handle 4K. It is also not uncommon for people to come on this forum with the same issue, and it often turns out their computer is not up to the task. 4K seems to have caught the computer industry unawares, and it is still trying to catch up.
Try playing back in VLC. If your monitor is not 4K it will scale it and make it "fit" in your screen, thus causing artifacts.
If you get stuttering or green line, boxes or breakups, that's a codec or CPU/GPU problem. I have an HP Envy X2 13" (CORE M 1.5Ghz CPU) and I can barely play back the 1080p@60fps. The bitrate on these files IS INSANE, but that's what you are paying for, the quality. If I re-encode the video using Adobe Premiere to about 20mb/sec it's way smoother, but some quality is lost.
In the end, if you are uploading to YouTube, it re-encodes and drops the bitrate regardless.
I wish there was a setting in the app to adjust the recording bitrate. I'd like to drop it down to about 16-20MB/sec for 1080p @ 60FPS. It would take up less space and let me play back the video on older hardware. For most of my needs, the lower bitrate is fine.
