IS IT WORTH IT? GH5s - No Stabilization

Too much post stabilisation can indeed make footage look very odd and at times give you a very uneasy viewing experience with stuff wobbling at the edge of your footage.

 

I know I've used it too excess before with bad (looking at it now) results.

 

Having the IBIS and OIS on the GH5, really does negate the need to use any warp stabiliser - when I have added it, its very slight and just removes the final bumps, and yeah the 1-2% you loose, you won't see in YouTube.

 

One thing for the GH5 would be running it at 60fps, a higher shutter speed and with the increase in ISO - something you potentially can't do with the GH5, the warp stabiliser then has twice as many frames (and sharp, clean ones at that) to calculate the movement, so you can potentially get much cleaner, stable results.

 

Interesting times ahead

I like this one and it is from your area pajpen

I love the night time shots on the snowmobiles, so clean! Still haven't decided whether to go with the 5 or the 5s haha, I'm torn.

Coming from gh4 i think having the ibis underwater is a great thing (for me at least)

İ have the gh5 now but i havent used it uw that much until now..this one i have filmed back in october . İ have 5000x2 lights but at some sceneries i havent used them at all...Unfortunately i cant remember my iso vallues .... those caves were dark actually ..

@lutfu

for your ISO values, just open/import the file in the free PHOTOfun software that comes with the cam. There's useful info available if you just right-click on the thumbnail, including ISO, shutter, aperture etc.

Thank you very much Matdiver 1234...I will try that..

About 90ft, cloudy day, no more than ISO400, around F5 with my LX100 (it's similar to GH4). This show there is a need of low noise performance for UW.

 

Everyone should know the limitation of their gear and push that limit and know what they want/need. So with GH5s, it may help with the situation in my case? May be. But without the IBIS, when you deal with cloudy day, deep, and strong current, would one choose Gh5 or GH5s? It all come down to how comfortable you feel about fixing, either fix the noise with NeatVideo, or fix the shakiness with After Effect Warpstabilizer.

KC - I assume this was ambient and you didn't use lights due to the distance. I used to shoot a D100 with Sea & Sea housing many years ago and moved to Gopro, but thinking of changing to something better. We are headed to Socorro in June

Ok - another question that may be stupid.....I dont see any mention of the Canon 5d Mkiv being good for video. Why?? (Large file sizes?)

Backscatter touts it as one of the best cameras for UW.

I shoot a 5d mkiii professionally for real estate and it is getting high shutter count and probably getting tired in next year or two..was thinking of 5dmkiv or 5ds and the next work camera, but if I can kill two birds with one stone might consider upgrading earlier.

Kristoph,

Yes I shoot ambient light in Socorro with Magic Filter. I know it's deep so I need to use custom white balance method to bring out the blue color. Unfortunately the visibility got bad half way into the trip so the white balance was challenging. At 3:30 into the video, you see some light on the Manta, it's a Keldan light from the boat's videographer, he swam around and shine his light everywhere and piss many people off, so watch out for people who abuse high power video light. Since I shoot ambient light, it's hard to swim on top of the Manta to capture the top side view of the manta because everything will be very dark. So it's a tricky experience for me.

As for your question of Canon 5DM4, I know 2 very skill videographers who are highly disappointed with it and decided to move to the 1DX M2 since the price is still manageable for them. Besides the file size, the big drawback of the 5DM4 is its crop factor, it's so bad that you can't really shoot good Wide Angle with it. I'm not sure if they corrected the crop factor through firmware update. Also, the 1DX M2 can shoot 4K 60 fps, so it's a highly desire feature with many professional videographers.

".... he swam around and shine his light everywhere and piss many people off, so watch out for people who abuse high power video light. "

Yeah, I know what you mean. Would have been even worse, i.e. more pink/red if he was closer.

I have very mixed feelings about these high power lights. I'm very impressed by the tech and the relatively small size, but generally I don't feel that comfortable shining really bright lights on turtles and our fishy friends! All down to personal preference I guess, but I wonder if it could influence fish behaviour in the long-term, maybe even push them to find somewhere less "disruptive"?

As regards noise, in my experience MWB can have as much of an impact as ISO. It seems like what's going on when you get a good MWB at 20m, say, and all the reds and yellows look nice, if you then point the cam at something out in the blue the "red boost" translates as noise. The few times it occurred I corrected it very easily with NeatVideo and reducing the red in Vegas curves, but the point is that at the same ISO there was no visible noise for the colourful reef shot.

Coming back to the GH5S discussion, have you looked at the Eric Nasso review at newsshooter : http://www.newsshooter.com/2018/02/22/panasonic-gh5s-good-bad-clean/

The GH5S colors looks really good.

I'm very much tempted to get this cam.

how do i add a picture from my computer. I got a quote on the GH5 the other day and it is pricey was not expecting that hahaha.

Taking his head shot into FCPX, the differences are very slight and I've got the GH5 shot to match the GH5s. So for a multi shoot, mixing them together looks really simple.

Still impressed with the colors of both!

The crop factor on the 5D4 might actually be an advantage for underwater work, assuming you can use third party APSC lenses. Generally, for underwater work you want as great a depth of fields as you can get, so smaller sensors are actually a good thing. One of the reasons I think m4/3 is great for underwater video.

Touching a bit on high powered video lights -- I've yet to see a single example of what I'd consider rich underwater colors that relies solely on ambient light, below 10 meters. You can't really beat physics unfortunately.. Red light don't penetrate very deep in the water column, and no amount of custom white balancing or red filters is going to bring them back if they're just not there.

Colours - are lovely... would be interesting to see how much he had to push that in post. But some lovely deep blues.

Alas we are spoiled with smooth video these days, with some stabilisation, that would removed probably all the micro jitters and made it even more spectacular.

I 've seen and shoot more jittering video than this with stabilized cameras

I love the colors too. Also did not find it jittering.

There are some very good cameras and lenses available those days, Not sure what more we could ask.

Are you guys professionals or mostly enthusiasts that want the very best quality ?
