FYI in Europe we have 50hz of electricity so we should use either 25 or 50 or 100 or … (you got the point) in this case it’s easier to avoid flickering and easier to cut the video. Easier for PC to handle with. Generally it’s recommended to not mixed frame rates.
I often use 60fps here in UK for smoothness of motion. Indoors or in poor light I use 30fps. Just to gain a stop or on the Ace Pro, pure Video Mode which is 30. Indoors, I just change the shutter to 1/50th for lights. 60fps looks great on TV's.
If I’m videoing indoors a lot, I use 50fps outside if I want smoothness (especially for vlogging and throwing the camera around) and 25fps indoors for lights.
That way, they can easily be combined.
For serious stuff where I want a more cine look, I use 24fps. Even done this on the Action 4 and it looks terrific.
So I use all of the frame rates really right up to 240 for slow motion.
If you’re producing video for just YouTube, I guess sticking with 30 makes sense, although in many instances where someone is running and gunning, I’ve thought that 60 would have been better. Especially when there is terrible judder going on.
So I don’t use just one frame rate. It depends on what the video is for or what it’s showing. The Frame rate also changes the ‘look’ of the video to some extent.
I guess there is more data for each frame at lower frame rates, but movement has to be considered as well and the lower ones can show judder, which is why I often go up if I'm running around.
I'll be over in USA soon and will be using 60fps, other than indoors when I'll use 30 with 1/60th shutter for lights indoors.
UK lights can be videod at 30fps as long as the shutter is at 1/50th or 1/100th.
At home on my TV, for low frame rates, I have black frame insertion which inserts a black frame between each picture so that what's called, 'persistence of vision' is tricked into seeing smoother motion; especially on pans. One thing that many forget is that in cinema, there is a blank screen between each frame to change the picture. Our brains are then tricked into seeing smoother motion. This doesn't happen on TV's or computers so slow frame rates can look juddery due to the pixels staying on until the next frame. It causes a problem for motion, so we either smooth it out with interpolation on TV which is in effect, making up more frames or a black frame can be inserted if the tv has it.
So I tend to avoid low frame rates if there is going to be a lot of camera movement....
