Slow Motion (Ursa Mini Pro)

PostTue Feb 13, 2018 2:02 pm

Hey guys,

I'm just wondering, you know you have to shoot in "windowed mode" in order to get 120fps, does that affect and bring down my resolution? If not: is windowed mode something that would be advised to be used for getting those micro close ups and a means of zooming in even more with a long lens? Would this be a type of standard practice?

Of course this will reduce the resolution, since you are using fewer photocells.
OTOH, if you are finishing in HDTV or 2K, you have enough resolution to do both slo-mo or zooming in.

Unfortunately this camera is not offering something like 3K, which would still give you more or less the resolution needed for 2K/HDTV. The true resolution is only about 70-80 percent of the number of photocells with a Bayer pattern.

Thanks for the reply. I am planning on specializing in wedding videos. Videos such as these tend to work best when a large proportion of the clips are in slow motion.

Consider the video below which was shot on the Mini Pro. To your eye does this look like it was slowed down from 60fps to 24fps or 120 to 24? After reading your post regarding the resolution limitations at 120fps and seeing that the video has a resolution of 1080 and up (all the way up to 4k although I suspect this was an upscaling and not native 4k) I am guessing it was recorded at 60. My amateur eye is also guessing this as well.

The reality is that with modern cameras you can get good 2K output if you capture in 2K.

For weddings, you'll almost never need 4K other than for stabilizing and such, and for events where you can't plan things ahead you can enhance your coverage with reframing in post, so windowed HD will be fine.

For montage-style work (like wedding shorts), I'd suggest that 120fps would often be *too* slow. Unless there is fast movement, it often doesn't reveal enough happening before the pace of the editing wants you to move on.

Second that.
IMHO, a very mild slo-mo will generate that dreamy, romantic feeling, not a massive one. Even 30 fps slowed down to 24 can suffice (and will give you all the resolution could need).

And if you’re shooting for the web, using 33 offspeed fps is another option to be used for 29.97/30 fps deliverables.

I see. So in that wedding video I listed above: that was probably recorded at perhaps 60fps and slowed to 24.
