Are there video recording apps at 25, 50, 100 frames/sec?

[gbynum]

I occasionally need to video a machine in operation and determine timing of machine movements. While VLC or Apple movie viewers will allow viewing frame by frame, converting the 8.33, 16.67, and 33.3 millisecond frame intervals to more human understood and readable on a graph 10, 20, or 40 milliseconds isn't intuitive.

Does anyone know if there is video recording software that records at other than the common US television scan rates? It may be the US software, but I don't see capabilities for the "rest-of-the-world" 50 Hz either; or is that their tv standard?

Are you referring to this?
But I see only 25. No 50. Maybe a 3rd party software

Those are the standards. 25/sec gives 40 msec resolution; I'd really like to get 10 msec resolution (100/sec) or better. I'm assuming, if it is possible, that it would be a 3rd party application. I do data acquisition at 1 msec and want to overlay the data.

Just to name one app, this is what I'm offered on a 13 mini with ProCamera [$13 USD].
So flat 10 or 5 ms intervals are possible.

EDIT: Same fps options for my iPhone SE 2020

Thanks; I have a 12 mini and will look into ProCamera.

I think Filmic Pro is probably the gold standard of iPhone video apps. Not cheap, but has a ton of controls.

@ignatius345 , it doesn't seem to offer 100 frames/sec or faster 200 frames/sec, my only criteria. I'm not "filming", I'm timing machine operations. Are those just omitted in their web specs but available? 240 * 160 resolution would be more than adequate for my application. It would be especially nice to get that at 1000 frames/sec.

I'm not sure you're going to get 1000 fps out of an iPhone. I rather doubt the camera sensor on an iPhone is designed to read out that fast but maybe I'm wrong. You can get 240 FPS if you use the slow motion mode, but that's it. I have a hunch that's the fastest that sensor can deliver.

@ignatius345 , I'm sure you are correct that we'll not get 1000 out of our phones today. I worked with really high dollar lab stuff 30 years ago that did 10,000 frames/sec; my customer could afford a weeks rental. (It was more than I earned in a month)

You'd probably have to read between the lines in my initial post, (I'm poor at that), but what I want is integral millisecond rates. 200 frames/sec (every 5 msec) for humans is far more understandable than 240 (every 4.1667) even though 240 is "better". I massage and smooth the 240 data in Excel and kinda fudge/scale to 200 oar 250 depending on my mood.

In all reality, 100 is more than good enough. Thus 120 should be, but 8.333 isn't, while better, as good as 100 (10 msec).

The choice @arw gave of ProCamera looks like my best option.

Thanks to both of you.
