I have been experimenting with frame rates on the M2Z. Whatever setting I use 264 or 265 mov or mp4 it will not record in 120 fps. I have even tried with Litchi but to the same effect. When I examine the source file in properties all the other formats show i .e. 4k 2. 7 etc and 25 or 50 fps they all indicate correctly. When I look at properties on a 120 fps video file it returns 30* . Whilst trying it just on bench closer inspection showed that 120 fps had the indication "slow underneath". I have an Ultra SD card and it could be that the mavic has reognised it as too slow and just defaulted to 30fps. Before I go out an buy an extreme card as suggested elsewhere on this forum it would be interesting to know if anybody else has this indication. I am in the UK.
