Is there any stock footage service that allows search by framerate?

I usually use Pexels and Pixabay mostly, as both of them are great services to get awesome stock footage. I usually shoot at 25 FPS.

When editing in Hitfilm, I'm always getting the things messy as different stock footage clips have different framerates and it always ends up with some sort of slutter when exporting the video, especially when 30 FPS videos being downsampled to 25 FPS (that's a 17% drop).

I'm missing the ability to filter videos based on their framerate on both Pexels and Pixabay. I've also checked, but it seems it's missing that feature as well.

How do you guys workaround this?
