The beginning is out of focus until I could select the young leopard face, at 0.19 is when the camera loses him. Well, you didn't lose it, just readjust the AF... ; ) Other than the bean bag, what else you used to stabilize it? OIS? What lens? The expensive Canon EF 400mm f/2.8L IS II USM? EIS too, I guess? What frame rate acquisition? Impressive result... : ) If this works in a jungle, imagine now for street photography! Quote Link to comment Share on other sites More sharing options...

Impressive result... : ) If this works in a jungle, imagine now for street photography! 25 fps, only lens IS, lens Canon RF 400 2.8 IS (rented). I don't use EIS as I'm RAW only other than when I need 120fps that I need to use 10bit log. On long lenses 70-200, 100-500 and 400 in my experience IS works better than IS+IBIS, and as you cannot turn off IBIS and keep IS on the R5 I always use the R5c for long lens work especially handled.

Emanuel Posted December 13, 2022 Share Posted December 13, 2022 This is the kind of information which matters to post into this thread on topic here: The different methods to achieve stabilized outcome fairly vary and there's no jack-of-all-trades in fact.

gt3rs Posted December 13, 2022 Share Posted December 13, 2022 One simpler scenario for AF, R5c on gimbal handheld on the vehicle moving, 70-200 at 2.8, 8K RAW 50fps slowed down 2x. Emanuel 1 Quote Link to comment Share on other sites More sharing options...

Digital IS is available in all modes other than RAW. 8k 50/60 is RAW only. 8k 24-30 MP4 supports Digital IS, 4k 100/120 also.

Come to my mind Artavazd Peleshyan, one of the greatest... Thanks for sharing, very worthy, this couple acted for you, both, WTH of a performance : ) One of the most beautiful things of the kind I've seen, such a thrill, pure cinema, simple but a true Epiphany made by pictures, the movement is absolutely competent, asked for... this is a cameraman! Not easy task at all... Framing brought to you some challenges you had to decide atm without losing the hand and before you could lose the shot, hats off!

Davide DB Posted December 13, 2022 Share Posted December 13, 2022 @gt3rs did you clean those clips? All reviews said that RAW is very noisy but you clips seems perfect. This clip is very noisy with several artefact on blue and black Quote Link to comment Share on other sites More sharing options...

I don't see anything wrong on mine even @ 1080p resolution other than the beauty of the footage, well shot and a bit pleasant grainy : ) What exactly have you found?

Can you post some grabs as samples about what bothers you actually? I'm viewing it at 4K on a 4k display. Clip @14" doesn't have a "pleasant grain" and even at 1'. That's noise. Tropical water in 10 ft of water means low ISO, high fstop and maybe a ND filter. This clip too has noise on the blue i.e. @57" Quote Link to comment Share on other sites More sharing options...

This clip too has noise on the blue i.e. @57" On 00:14 I don't notice anything but on the rest, yes, you're right although that looks like to me the introduction of compression artifacts, not necessarily coming from the native files : ) You're watching processed pictures, not the original acquisition. Anything adultered is nothing about the ones SOOC. You can only have an accurate idea when you face that stuff the camera directly produced, shot by the device without any further processing or you can fairly infer that's noise introduced later on. shooter 1 Quote Link to comment Share on other sites More sharing options...
Emanuel Posted December 13, 2022 Share Posted December 13, 2022 In any case, it is natural the shooter had often used a very high set of ISO values which will naturally increase noise artifacts more visible in the dark areas such as those blacks and blues. Not apples to oranges. That's the only way to compare tools. shooter 1 Quote Link to comment Share on other sites More sharing options...

Only the leopard at iso 16'000 has NR applied, mostly chroma noise reduction. All the others have zero NR applied. RAW is more noisy and rightly so as most camera apply NR to 10bit Log, RAW should have none (I think a bit is there anyway but not sure). Imo this is great as you can fine tune the NR that you need, you can even go fancy and apply NR to only specific area or color range. If you open a R5 RAW picture in LR you will see that by default it apply color noise reduction, so some NR on RAW is needed even for photos. Although imo a well exposed ISO 800 (base iso) RAW video does not need any NR. Not knowing the settings and what was done in post out of the RAW of the video that you posted is impossible to judge imo. In general I find it better to expose to the right with Canon RAW and lower the black in post than raising the shadow. Davide DB 1 Quote Link to comment Share on other sites More sharing options...

gt3rs Posted January 2, 2023 Share Posted January 2, 2023 I did finally edit a first version of the SA video. Canon R5c, DJI RS3 Pro, RF 70-200 2.8, RF 100-500, RF 400 2.8, EF 24-70 2.8. All shoot 8K RAW 50fps other than the Cheetahs running that are at 4k 100fps. Davide DB, herein2020, Django and 5 others 2 6 Quote Link to comment Share on other sites More sharing options...
