Bmpcc to 60hz monitor?

PostSun Mar 12, 2023 8:09 pm

OK, I know the best answer is “Buy a director’s monitor.” Well, I would but I’m not making any money doing this so here we are…

I’d like to output from my 6k to a cheap computer monitor for a director to watch along without breathing down my neck. Wanting to shoot in 30 or 24 fps. My monitor, and all I’ve seen in my deep dive, only works at 60Hz or above. So if I shoot 60fps it works, anything else it doesn’t. There doesnt seem to be a way to record in 30 and output in 60. So I’m thinking I’ll shoot in 60 to deliver in 30. What shutter angle would give the most close to 180 doing this? I’m thinking you’d need to double the blur so you’d halve the shutter to 90. Is that good math?

If you want to mimic the blur of a 180 degree shutter angle shooting 60 fps, the you could shoot with a 90 degree shutter angle at 30 fps. But I don’t think that will feel the same as shooting 60 fps.

If you decided to shoot at 60 fps so that the director’s monitor works, you could record with the shutter angle at 360 degrees but in post only use every other frame on a 30 fps timeline. Then your results will look normal and be virtually indistinguishable as if you were shooting 30 fps on the camera.

Absolutely test the entire workflow on your own to be sure you get the result you want in post before you do a production shoot.

I’ve never tried that trick, but I think you would select dual card recording in BRAW with 360 degree shutter angle so that each card received every other frame, ergo each card effectively records at 30 fps with a normal blur. Has someone else verified this works?

If you are okay with having the director monitor from an IPad or a smartphone, you’re much better getting a video transmitter like a HollyLand Mars, Accson, DJI, etc. Changing the shutter angle to accommodate motion blur has other challenges too.

I decided to just pick up a small, used TV. Works just fine at any framerate. Needs AC power but that's okay. The mount to get it onto a light stand will cost more than the TV LOL.
