Camera: Panasonic GH5S
Lens: Lumix 25mm f/1.7
Filter: K&F Concept Slim Vari ND Filter
1080p/200fps PAL (no sensor crop)
WB: 5600-5900
ISO: 400-640
PP: V-Log L
Music: Be Still The Earth - Fortress via artlist.io

Just a few quick shots in V-Log L I shot with my Panasonic GH5s. In post I just applied the Panasonic official V-Log L to Rec.709 LUT plus slight contrast and WB adjustments.

I did not apply any noise reduction in post, as I wanted to see how the 200fps footage behaved in V-Log with a simple Rec.709 conversion and no noise reduction for a super quick and dirty delivery.

Due to the thin 8bit 420 structure and stretched bit rate, aliasing and moire are visible in a few of the shots. It is also slightly noisy and softer than normal speed 1080p - but nevertheless, footage looks organic with natural rolloff in the highlights despite the drab January English afternoon.

The slight noise is not an issue for me. With a pinch of NR in post, (Resolve or Neat Video) this footage can sing. 200fps is the maximum frame rate (in 50.00Hz PAL) in which the camera does NOT crop. 225 and 240fps crop the sensor further by about 15-20%.
 
boy, is it me or does EVERYTHING look interesting at 200fps!!!

that said, footage is impressive.

noise was not an issue for me. low-ish iso could have been part of the reason.

care to share f/stop?

420/8bit will not offer much leeway with color correction.

how many years away will it before before 200fps/422/10bit will be the norm.

i only wish the storytelling and the stories told will advance as much as the tech ;-).

thanks for the effort and the sharing.

thumbs up.

be well.

Thanks for sharing. Looks good. Does the GH5s allow you freedom to select your shutter speed when in this mode? just wondering if there are any operational restraints like grabbing focus or changing WB etc... when you are shooting slo-mo.

Looks like GH5s 200fps seems to hold up a lot better than GH5 180fps... why? Could this really just be because of the lower noise? Seems like the codec isn't as stretched.

Thanks mate. Those shots were literally the first thing I shot with the GH5S as I received it last Thursday and have been busy with other projects since and have not had the time to delve deeper.

From memory, I think I had syncro-scan enabled, you can change shutter angle from 250 to 200 degrees in small increments up or down in 200fps (this is PAL). In NTSC the crop starts after 192fps. You can also change WB. I focused manually throughout the shoot, did not test AF.

Maybe the lower resolution sensor plus fast processing allows for less tech gymnastics?

I also noticed that rolling shutter basically does not exist - I think the GH5S has a faster readout than the GH5, definitely faster than any Sony or Canon DSLR I have ever used.
 
Thanks. With the great noise performance I was thinking 320th or 500th/sec shutter might be good with 240fps if the camera allows it. I am wrestling with the GH5 vs GH5s choice. I do use 240fps on some projects so there is a draw towards the GH5s but IBIS is pretty cool as well.
 
So we can confirm that the 180fps of the gh5s is better then the gh5? So far it looks like there is a less aliasing and moire.
