IS IT WORTH IT? GH5s - No Stabilization

Recommended Posts

Yes, I used to use the A7RII underwater. Now it's relegated to land-only duties.

Yes. There's quite a bit of extra contrast added. Adding additional saturation after the LUT only produces less natural-looking colors. My point isn't that the color-corrected result from v-log looks terrible -- it just doesn't look as good (and certainly not any better) than the color corrected result from shooting in the standard picture profile in 8bit.

 

Basically, when you choose to shoot a desaturated image initially, what you're doing by compressing the saturation range (as all log formats do) is throwing away the subtle differences between shades of color. Adding saturation back in post doesn't bring back those subtle differences -- they're gone forever. Shooting in 10 bit does alleviate this to some extent, but at the end of the day, you're not gaining anything. Probably better to just shoot in 10-bit using the standard picture profile.

Have you tried HLG? Can't remember where I read it but someone was actually advising to bump up the in-camera saturation and take saturation off in post if needed.

Yes, I've done a few tests with HLG. -- for some reason, if I bring the footage into a regular (non HDR) timeline in FCPX, the colors are all wrong and there's no easy way to normalize them

Yes, I've done a few tests with HLG. With underwater shots, for some reason, if I bring the footage into a regular (not wide color gamut) timeline in FCPX, the colors are all quite a bit off and there's no easy way to normalize them. So I prefer using VLOG over HLG for that reason -- at least with vlog there's an easy official LUT to covert it to REC709 that will get you in the ballpark for color correction. But as I mentioned, 99% of the time I think you're just fine shooting in standard without any sort of log profile at all.

 

Regarding saturation, theoretically I think you'd indeed be better off removing saturation in post rather than adding it in terms of preserving as much color shade separation as possible. But the best option IMO on cameras that don't record in raw is to get the saturation in camera as close to the final output you want so you don't have to do any tweaking in post. That's why I prefer the standard color profile over CineD or Vivid/Landscape. CineD I find desaturates the footage in a way that looks unnatural for underwater shots and it's hard to get them to look good by just adding saturation in post. Conversely, Vivid/Landscape are a bit too saturated. If you reduce the saturation in post, you get a result that looks ok, but not any better than the standard picture profile IMO.

Correct me if i am wrong but the idea i have about HLG is that it is designed not as a VLOG profile but as an out of the box HDR ready profile (meaning you dont have to do all this grading that is required with VLOG). From what i read its designed to work on a wide gamut timeline and then carries metadata that allows non HDR monitors to play it as such and HDR monitors to take advantage of it. I think Resolve has an HLG to 709 lut but not 100% sure need to check it.

I just found out that FCPX 10.4 also has a "HDR Tools" effect that allows you to map from HLG to Rec709 -- but by default the conversion doesn't re-map the highlights into the 709 range, it just cuts them off. Pretty ugly effect underwater if you're shooting upwards into the water column.

GH5, CWB with ambient light at 10m, no red filter, standard picture profile, 4k60fps in 8-bit 4:2:0 at 150mbs.

 

Before/after simple color correction in FCPX (WB->warmer/+magenta; crushed shadows)

For the record, I tried shooting same scene at 4k24fps in 10-bit 4:2:2 400mbs with v-log and was much less pleased with the results after applying the official lut and trying to color correct the scene. I think you give up too much color information when shooting in v-log.

I'd be very interested to know more about your colour correction process as i will also be shooting mostly in 4k 60p 8 bit.

Hey guys I finally did it after many years mulling over the options, I am a Proud new owner of a GH5 in the Nauticam housing. OLY M.Zuiko Pro 7-14 and the 60mm macro! Little bit of buyers remorse as it was a lot of money for me but very excited to get in the water and learn. I've been shooting GoPro for years and have some pretty good content but looking to up my game so to speak. You all can expect this NEWB to be asking a fair bit of questions on Wetpixel and don't be surprised if you get a PM from me in the near future as all you guys are amazing. I am open to suggestions and critique about method and settings, workflow, and equipment options. I currently am limited to sola 3500's with diffuser and no monitor yet. My quote for a monitor package is 2900 USD for the 502 HD. That might be a little rich for me at this stage. A better light package is for sure in the future.

 

If you had to make a choice on a better light package or monitor for video which would you go for first?

Maybe this needs to be moved to a different thread.

I actually unboxed my monitor yesterday (smallhd 501 in nauticam housing) and I don't regret the purchase one bit.

To answer your question tho I guess it depends what u want to shoot most, if macro is your priority I'd definitely pick up a monitor as your lights are sufficient for that.

If wide angle is your main priority I'd definitely get better lights before a monitor. Monitor isn't really a necessity at all, but a very nice addition to primarily macro as u don't have to bury your head in the sand

I use the 45° viewfinder for macro. Less bulky and pricey. I like the fact that I can concentrate on the subject by looking through a viewfinder.

Congrats on your purchase, gearbow.

 

I‘d go for lights first, then monitor.

Definitely get the best lights you can afford before a monitor.

Yeah. In general, you want to get the things that allow you to shoot what you couldn't otherwise film first, and things that don't really give you any new capabilities (but do allow you to do what you were doing before easier) second.

 

I think the monitor is a lot more essential for macro than for wide-angle shots. And the lights vice-versa. So decide what you're more interested in filming first. For the type of high-magnification macro that would benefit them most from a monitor, you'll also what a tripod of some sort.

Good choice.

The GH5 is definitely the better choice for underwater than the GH5s

 

Having both, I always reach for the GH5 - it’s just more complete.

 

As to lights / monitor. As I and others have suggested - get Lights.

 

Depending on budget. Go bright. With tech these days, there is little point looking at less than 7500lm and CRI90. IMHO

Thanks Trickster really value your opinion.

Out of curiosity, what made you choose the Oly Pro over the Pany 7-14?

I don't know I read somewhere that the f2.8 through the whole focal distance is good for video?? I see now it's kind of a pain in the butt. I have to use a port adaptor and a glass port.
