Screenflow 6 is very frustrating!
This is a 10-second clip starting from around 5-minute into my 10-minute recording.
I'm using late 2014 iMac 27" 5K, running OSX 10.12.5. Posted my spec as photo.
The video is severely out of sync, and I couldn't get my mouse pointer click effect working.
I've tried using all different resolutions available and also tried plugging into a HD TV so it gives me 1080p option. I thought it's because the resolution was too big so it couldn't process quick enough. Nope. It doesn't even work on 1080p.
Needless to say the FCPX that I'm demonstrating is running very smoothly.
What is going on Screenflow?!
This is extremely frustrating and I've been testing for an entire day.
Have you updated to ScreenFlow 6.2.2?
Since many professional FCPX trainers use ScreenFlow for their tutorials I'm not sure there's in inherent issue so it may be related to your workflow.
Full screen on a late 2014 27" iMac would be 5120 by 2880. Using an HDTV may give 1080p but it also will demand resources from the GPU which ScreenFlow may also be using.
To test you should start with a "control" using limited resources.
Remove all peripherals including additional monitors.
Reboot the computer.
Play a 1080p video in Quicktime X and do a partial screen capture of just the video.
Then check to see if it maintains sync by playing back the screen recording in ScreenFlow.
This will let you know if the issue is related to the resources being used in FCPX in the Quicktime X recording is OK.Reply
Ocean Ho It may depend on the resources used by FCPX including what is playing in the timeline as FCPX may be doing a real time decode for playback. That may be impacting the resources used by ScreenFlow.
Since playing a movie file itself is not an issue, the next step might be testing an Apple ProRes file in FCPX since that would be the least decode resources. Do not put FCPX in full screen mode as that can also impact resources.Reply
Take a look at the Energy tab in Activity Monitor and then do an export with ScreenFlow. You should see a pretty good spike. Some systems will reveal the graphics card as "high perf." Not exactly what you may want or need but a possibly useful indicator.Reply
