I'm in the middle of shooting a documentary on my BMPCC4K and I've so far shot BRAW at 30 fps and I'm finding most broadcast/cable outlet want 29.97 fps. Two questions, Can I easily convert what I've shot to 29.97fps? If so, should I keep shooting at 30 fps and make the conversion on the finished project or switch over mid stream to 29.97 fps and convert the footage I've already shot?

For broadcast release, I always shoot 29.97fps, 30fps is not a Broadcast frame rate. You can concpvert the 30fps to 29.97, but shoot the rest at 29.97 to avoid making extra work out of this project.
Cheers

I live in PAL land, so not sure if my advice is worth as much as someone in NTSC - but I would shoot the whole project at the same frame-rate and convert what you need later. Keeping everything the same will be much easier to manage in the long run.

DO NOT change frame rates mid shoot. Finish it out and convert it all later.

23,976 = wrong way to do every times (born for Blu-ray false standard and keep electric compatibility with ‘50 years standard)
24 = movie theater
25 = pal land
29,97 = ntsc land
30 = computer monitor and mobile screen (all 60 hz)

The best is to shoot at same rate, the other option is to convert later but only with good common sense of what you are doing and what result you could have. If you have doubts about conversion avoid it and shoot on native delivery frame rate. A lots of headache avoided.

The choice between 24fps and 30fps is a hotly contested issue on YouTube, the main video platform, and there are influential proponents of 60fps.

It is clearly an aesthetic choice and not a question of what’s “correct”.

It’s a tech question not aesthetic question.
There are some standard about device delivery not a my interpretation.

24p on 30p device (60 hz monitor or device) mean device create 6 frame every seconds (in some way, with jump, interpolation, pull down 3:2 on tv and more) because you cannot change the scan of device to reproduce correctly that kind of shooting.

Most of monitors cannot reproduce a 60p video, only reproduce 30p and with many algorithm create other 30 frames, like most of tv.

Remember that most of YouTube is on mobile, And also if you have high end device, most of them not reproduce higher frame rate or different frame rate then original multiple of 30p.

Most of tv cannot play 60p, but give you with fluid motion (or other interpolation tech) the apparenze of 60p/120p and more.

If you have a good video projector you can see the real difference between 24-25-30-50-60p changing frequency of projection.
If you have a gaming monitor that allow you to play with different frequency up to 144hrz you can play different frame rate, but with common monitor / device mobile you not see real FPS over 30p.
And remember that not all player drive correctly faster monitor, for example I had a 144hz monitor but only by vlc I can see at high frame rate videos, many other player loss frames during playing.
I understand that is not simple to see be cause most of modern device had many kind of interpolation, advertising show us capability that are not completely real.
If you not believe, try to put a simple video with timecode at 24p, record with a external camera at 30p and see if every frame there are the single timecode number or sometimes you see distortion of number or sometimes some timecode are repeated
Later try with 60p movie and check on tv or monitor if you can see every single frame or you miss something.
With motion picture your brain lie, with timecode no error, no problem of sinc

Testing monitors and device for delivery was once of my work in test last twenty years.
And unfortunately I not see so big improvement on frame rate where I would like to see more evolution

What you talk about aestetic is not frame rate but shutter changment. If you shoot 24p you have more blur than 30p, many people think more mb is more cinematic.
Shooting with different shutter speed give you different aesthetic and me too prefer more blur to blend better motion, but if you shoot with different frame rate from reproduction media you have jump frame which is less cinematic and I hate it.
Try to shoot some panoramic motion in 24p and see on web, show me where not have jump of motion
Try to shoot some panoramic motion in 30p but with 216-270 degree of shutter angle and you have all blur that you want without interruption of motion.

There are people who are actually making videos for YouTube, which like it or not is the main platform, and people who like to theorize about it. There is no doubt about who are calling the shots.

In both of the threads that I’ve seen on this forum that relate to YouTube, there has been a disconnect between what some people here think should happen and what YouTube filmmakers are actually doing :)

30p is great for social media and UTube, but the original question was to do with Broadcast delivery and not UTube or internet applications. The Pocket 4/6K supports all three, and you should use the one that meets the delivery standard. It does not matter what we think looks best, it is what the customer wants/needs, that counts.

If you've already started shooting at 30p, finish that way so it is all consistent.

When you set up the project/timeline in resolve, create it at 29.97fps as that is your delivery format.
