Hi guys. I have found that any attempt to take still photos UNDER 1920 x 1080 F120 triggers a warning "failed to take still photo" on my controller. Impossible at lower resulution and/or lower FPS than this. :-( I am new to my Q500 4k and this fact caused surprise to me. Is it normal or had it happen to any of you?? And last one: Is it normal that videos that I take in 20 seconds for example, reproduce in 28 or 30 second in my PC, when filmed with upper than F25?? Is that slow motion or what? BTW, I am not a photography expert, as you can guess. LOL. Also, if recorded sound, It plays totally desincronized of the image! Looks like sound plays in real time (ends in 20 seconds) while image plays for 8 or 10 seconds more! What the heck??? I found by testing, that videos made on 1920x1080 F25 were reproduced in real time, image and sound. If I go any higher, things mess up. Thanks to anybody who can help!
