Question

Reducing Frame Rate

I'm shooting a walkthrough tour video of a building, and shot it at 60 fps with 1/125 shutter speed. The reason is I knew I wanted to slow down certain shots, kind of like MTV Cribs style. I'm now starting to kick myself for shooting in 60 fps because I feel it may not look as professional. This is one of my first videos so I'm really concerned with the result.  My thought process pre shooting was I could always convert it to 30 fps by either exporting it that way or changing the timeline to 30.

I'm now realizing that it doesn't look as great when I do so because I shot at 1/125 shutter instead of 1/60, which wouldve been optimal for 30 fps. Is there anything I can do to drop the frame rate to 30 without losing quality due to the high shutter speed? Will time interpolation settings like frame blend help in this case?

Thanks

Agreed on the above comment. 30fps looks very strange, like an early 90's camcorder or something. The brain processes 24fps most easily so it looks the best. Nearly everything in Hollywood is shot at 24fps. Next time I'd shoot at 120fps, not 60fps. It will give you a buttery smooth slow-mo that just looks great.

So, if you go to your clips in the project panel, click the first one, hold shift and click the last one, this will select them all. Then right click on them and go to MODIFY. Modify will give you the option to INTERPRET FOOTAGE. Click this and it will bring up another screen. At the top there are two options: Use Frame Rate from File; Assume this Frame Rate. Choose the Assume the Frame Rate option and in the small bar next to it, type in 30.00

You can also put in 24.00 but it may not come out perfect. Try it out.

If you want to slow down some parts still to make it look stylized and cool, follow this video. It really helped me and I got some sweet footage because of it.

Many TV commercials (broadcast at 30 fps ) look very good to most people. It can be argued some stuff shot at 30fps to be transferred 1:1 ( one frame film to one frame broadcast ( two fields per frame)) look pretty nice.

This TV commercial was shot mostly at 30fps, but some was shot higher for the slow motion (which ultimately is 30fps broadcast).

Is nice donkey commercial.

I think the interpret footage thing to 30 should look fine for you. It has nothing to do with exposure at 60. That's already a done deal.

I think your problem is that you shot 60 without wanting it to be slow motion, so now you have to drop every other frame to get 30, but it shouldn't be terrible (hopefully ).

30 doesn't look all that "professional" either.  You really need to be shooting at 24 fps with a 1/50 shutter to get that "professional" film look.

    Hi AdamF,

    Can you upload a small sample somewhere so we can inspect it and to help you find a solution?

    Thanks,
    Kevin
