Hello,
I thought it is usefull to give this topic its own thread.
One week after I had bought and played with my MAVIC PRO I expierenced suddendly very choppy vidoes while recording and even the message "CPU load ... on mobile device" appeared a few times. Espcially in Active Track - Follow mode - Rounding you could litterally see how the images got badly choppy as soon as I pressed the record button.
My Set-Up:
- Mavic Pro with 64GB U1 Class 10 miniSD
- RC with Iphone 6
- Video Caching while recording in mobile device enabled
- Resolution 4k
- Recording format: mp4
Playing with a number of setting, calibrating everything didn't help. I reduced resolution to 2.7k format: No improvement.
I was already guessing that it was somehow related to my Iphone 6 because with my crappy Samsung J3 it was better. Also the recent CPU-Load alarm concerend me.
In this forum I found the hint to disable "Video Caching while recording". It did it ..... and the problem was solved. Smooth movements again. :-)
But I was still wondering why I didn't have the issue at the begining with "Video Caching" enabled . So I compared the videos I recorded at the begining with the later ones.
And found it:
The first videos I recorded were in ".mov" format and had 1920x0180 resoltuion (factory settings).
The choppy videos were recorded in ".mp4" and 4k-format.
So obviously processing mp4-format datastreams demands so much processing power from the Iphone6 (or IOS in general) that it made the videos choppy and caused the high CPU-load.
I moved back the ".mov"-format, enabled the Video Caching and stayed in 2.7k resolution. I looks ok.
Based on this my recommedation is
- For IOS-devices with "Video Caching" enabled only record in ".mov"-format
- If you expirience any performance issues on your mobile device connected with the RC (choppy videos while recording, CPU load issues) disable "Video Caching"
Best regards,
Knut
