Are file sizes for 24fps vs. 30fps proportionally smaller all other things being equal?

Maybe not. What's the difference? It is better to load only in 30 fps.

I was just thinking, does it make sense to make my files bigger by shooting at 30fps? What benefit would there be in a world that accepts 24fps. Why not save a little file space (and processing resources) and go with 24fps? Is there a downside?

Of course there are disadvantages:
1. Video becomes less smooth.
2. Buyers buy videos for projects at 30 fps in general.
3. Television in buyers' countries is 30 fps standard.
4. You can make 24 fps out of 30 fps, but you can't make 30 fps out of 24 fps.

Yes, valid points. There are solutions for #4 (3:2 pull down). I guess it's really hard to know how much of an impact it would have on sales, and of course we never get data from the stock houses how many 24 vs. 30 fps sales they have (#2). That would settle it. Odds are 30fps is probably a "safer" bet. I just hate those big file sizes, anything that would reduce them would be nice....but of course not at the expense of lower sales.

According to my observations, mostly people load 30 fps there. Use H.264 codec, lower compression bitrate, shorter clip length, but 30 fps is the industry standard. All other fps, like 24 or 60 is a risk for sales.
And what difference does it make to you what size the file has, the main thing is that the stocks are accepted

Yea, you're probably right, for the small savings in file size, not worth potentially risking sales.

North American and Japanese TV use 30fps as well as a few other Asian countries. The majority of countries use 25fps for their television.

4. You can make 24 fps out of 30 fps, but you can't make 30 fps out of 24 fps.

For countless decades, many of the big budget US TV shows were shot on film (at 24fps) and then converted to 30fps. I could list many examples of these - Bewitched, MASH, Charlies Angels, The Six Million Dollar Man, Happy Days, Miami Vice, Knight Rider, The A Team, LA Law, NYPD Blue, Ally McBeal, Sex & The City, Seinfeld, Scrubs and so on.

Plus these days, there are a number of big budget TV series shot on digital (at 24fps) within the US. Though I wouldn't be surprised if the majority of US TV content is shot at 30fps.
