Smart variable framerate

[Uberprutser]

So what exactly is so smart about the smart max 60fps output setting? And why is there not a max 50fps option? My camera only does 50pfs, like most in the 50hz regions.

Hi

You can use the custom setting and export at a variable frame at 25 maximum 50 fps or use constant frame rate exporting at 50fps

Yeah, but why is the 60 fps option called smart?

And when would you use a variable bitrate. Would it be a good idea to use a variable bitrate for footage without a lot of movement? (static tripod recordings)

To save some upload time.

Note that the H264 codec, under the mp4 wrapper in a test here, produces a VBR export, even when CBR is specified.

Still, I would like to know what's so smart about this option.

When exporting using this variable max 60 fps setting the files come out a bit smaller. Perhaps 5%

That can be a lot on a shit internet connection.  It looks good to me.

But I'm not sure if it's smart to use this option. Since the footage I shot is only 50fps (I think variable 12.5 - 25 fps might be a better option)

Also for some reason it keep changing to the variable frame rate to (30 fps min / 60 fps max) setting. What's that about?

So, anyone out there, who can say something smart about using a variable frame rate?
