Sony A7RII in video mode changes frame rate randomly


Recommended Posts

I have my frame rate set at 29.97fps, yet periodically and for no reason, it changes by itself and shoots at 23.98.  Not always, not often, and the settings in the camera still SAY 29.97fps, but the actual footage is 24 fps.

 

This is making me crazy and messing up things as you might imagine.  

 

Anyone else having this issue?  Any ideas as to how to fix?

My A7RII is still fairly new to me, but your report above made me want to test the frame rates for both systems (PAL/NTSC) to see what info was reported and if it was correct, and how various players handled it.

 

For every setting recorded, the associated XML file correctly reported the frame rate & resolution, both in the MEDIAPRO.XML file, and the individual clip XML files.

Playing a clip in an external player (eg VLC) plays back at the capture rate, but after dropping the clips into RESOLVE each clip correctly reported the capture frame rate, and then played back at the project rate (as expected).

 

 

Just out of interest, how or where are you reading that the "actual footage is 24fps"?

....and of course, its never TRUE 24fps, but a subset of NTSC so it reports as 23.98 but in reality is 23.976.
