  1. Even more interesting. If you force youtube to h264 there are no glitches conclusion their vp9 codec has some playback problems of some description!
  2. YouTube is introducing around 1 glitch per day. The clip was uploaded 10 days ago and checked no issues. On day 1 was fine too. On day 2 had 1 glitch and on day 3 it has 2 glitches very interesting trend. I wrote them about it not sure I will get a reply. Even more interesting if I download the video or I scrub it in the editor there are no issues, perhaps they have a playback problem? No voiceover is intentional I didn’t want to do a documentary just to relive my walks I used quite a few lenses the bulk is with 50-200 sometimes with teleconverter some of the closer shots 200mm + 2 TC All on monopod I only used tripods for some of the landscape shots Sent from my iPhone using Tapatalk
  3. Some people have gone the bathtub route but I decided to expand my horizons to land wildlife photography. It has been a journey and although the challenges of long lens work are not exactly the same stability and field work is fundamental like it is underwater a bit like buoyancy. Hopefully makes for a pleasant and relaxing watch while we wait for things to pick up again Stay safe
  4. Why would you want to have an anamorphic lens underwater? Anamorphic lenses give specific look and flares that underwater are generally not desired (we are all fighting flare) as it reduces contrast Water has already a dampening and contrast reducing effect on the image it does not really need any help? I am a bit confused by the purpose of this experiment.
  5. To my knowledge this metadata can only read by catalyst the Sony provided application but may be wrong Obviously it crops... Sent from my iPhone using Tapatalk
  6. https://interceptor121.com/2014/03/15/floats-and-float-arms/ I have tables for all the arms and set ups combined. You Z330 with dome may be neutral so check them individually
  7. I am not sure about the stabilisation issue. I generally do not stabilise my videos and the A7S has IBIS so am not clear what is going on. Someone said the camera captures gyroscope information if it does that on a log base this would be fairly easy to stabilise? Not sure if this lovely lady has the technical background to answer the kind of questions you or I might have
  8. Lots of slow motion and a wide lens are not exactly the proof of the pudding
  9. The dome is too small for wide lenses.It is really for maximum 12mm. You need the 7" for wider lenses however with this lens being so small it would most likely vignette It would be better to try a shorter port like the 4.33 dome
  10. There are some conflicting views on this lens. Things to consider 1. It has only 5 aperture blades this is intentional to make sunstars 5 rays but this creates really bad background how would it work in water 2. A guy I know bought it this lens has tons of flare how would it work behind a dome especially not coated in acrylic
  11. in general the filters have to match each other that is the most important aspect I have studied the absorption curves and this is how you find your match I have a whole load of rolls in my loft including green water but I do not even remember what I set it on The filters used for green water have higher transmission however the number of particles etc makes it really suitable only for close up work and therefore it is questionable if this is the right path as once you are close there is no benefit over just using lights Ambient filters are for wide shots where subject come towards the light they are not for widespread general use nor close up work
  12. With ProRes RAW you need to either set a custom white balance or set a color temperature. The camera no longer works in auto as it does not keep a dynamic metadata file. You then can edit the color temperature but not the tint So at the end when you need to white balance anyway there is limited benefit of ProRes RAW. I have spent a few weeks testing it with the S5 and it is not actually the leap I was hoping to get. It also does not support lens corrections, noise reduction etc so each clips has to go into neat video the moment is a bit dark. The BMPCC and ZCAM however do not have any lens corrections anyway...
  13. I didn’t want to be negative on this video She is a lovely lady and a good diver underwater video however is very technical and the set up of this video with lag and unclear audio was not great Perhaps a recording would have been better? Sent from my iPhone using Tapatalk
  14. Sony is using stacked since years on their full frame It is a question mark if this is going to be allowed to 3rd parties So far it hasn’t Stacked sensors are important for burst and video however they are not required for underwater stills Sony themselves makes their video focussed camera out of the exmor R line We are no longer in a situation where the market is booming so catching up is harder when you are lagging behind and have no money I think the biggest issue for underwater photographers is that for most the audience is made of older users who like a DSLR so they are the ones who will adopt whatever comes as late as possible What will this rumoured camera going to do for those guys?

  15. Large camcorders big box style housings from gates et co have been around a while and also Nauticam has some Once your rig has inertia is good to provide stability unless you are in the current and that big box takes off with you Those solutions however are not existing for digital camera form factor which as you noted is probably the worst in terms of trim With the zcam though you always have a monitor though that is going to throw things out Dean spreakman has done some really nice footage with zcam e2 but now has moved on Sent from my iPhone using Tapatalk
  16. I think she is using log simply because it gives the vibe of ISO 12800 or whatever it is and then no LUT is applied aka she is editing manually Sony applies extensive noise reduction and sharpening to log footage in this camera so doesn’t look like the log of other manufacturers When we measured low light performance and dr for raw this camera did worse than Panasonic s1h and s5 but with artificial illumination DR is not a consideration and frankly almost never is underwater Sent from my iPhone using Tapatalk
  17. Yours are dreifish are good and so are some other holiday divers here in the gallery show case I have made note of a few The videos of Adamson etc are excellent the way he controls the light but I am not a fan of critters slideshows What I do not like are the stereotypes that we seem to be victim. Cinematic style? Or just a way to hide buoyancy flaws and other issues I also think like you said we have a fundamental question in terms of story telling vs documentary fish id type
  18. The Z cam work is the typical 60 fps slow down that is painful to watch Ripping current and where is it? Slowing down half speed or more completely removes the drama from the clip
  19. Dustin Adamson is not a holiday maker He must have spent over 100 days diving abroad in the years he was so prolific Why did he do that if he had no ambition to be a pro I don’t know There are many people that do 7-10 trips per year with the objective of winning some competitions On tripod shots for sure IBIS doesn’t matter but if you asked Nick Hope between GH4 and GH5 I am sure the answer would be GH5 Macro/ critter video is not my main focus I prefer wide angle this goes also for my photography so I have to admit in the last years I have not been particularly focussed ok stabilised rigs On land to work on a tripod I use a fluid head however this is based on a ball bearing and would not work underwater so all your underwater shots tend to be very static while on land tilt and pan makes things more interesting when things move assuming you are able to follow focus Sent from my iPhone using Tapatalk
  20. No IBIS doesn’t react at all to finning it only compensates micro shakes I use it for panning shots on monopod. Electronic stabilisation instead creates all sort of issues. Am talking about a 5 axis well implemented IBIS here not all cameras are equalThe issue affecting cave divers with edge pulling is due to lens correction that when combined with IBIS gives side effects on extremely wide rectilinear lensesThis problem affects real estate videographers that use gimbals and in general if you want to use a rectilinear lens in caves you do need to turn IBIS off IBIS today is much more sophisticated than it used to be and I have it always on with my monopod and my tripod Those are shots at 560mm equivalent to give an idea Daily Roll 26 February 2021 For me a wildlife underwater camera without IBIS is worthless. If I don’t need it I can turn it off but I like it to be there it makes a significant difference to the keeper rate Sent from my iPhone using Tapatalk I
  21. What are you saying Ben? That a tripod is better than handheld? That is obvious Those guys are trade not holiday makers and Nick has been both resident on a boat and local They are not a representative case for a holiday diver and none of this means IBIS is not required Or are you saying all dives are suited to a tripod approach??
  22. My point is what does Nikon bring to the mix Autofocus not really Better video not really Maybe better build and ergonomics?? When you are late in the game is always hard Nikon does most of their business in cameras the end of DSLR will no doubt impact them if they keep not having anything special in their cameras None of the z6/7 I or II are better than their competitors on any count Sent from my iPhone using Tapatalk
  23. You don't need Xit404 parts the difference between those two guys and a holiday diver is that they are always there If you go to the same spot 1000 times and take a selection of your material will be great You use the same equipment in your 1 week trip you are guaranteed not to achieve the same results it is just life What XIT does is the ability to adjust the height. I don't find that an excessive issue to be frank once the rig is set it is set there is no movement while ideally you want a pan and tilt head which does not exist yet underwater
  24. Well actually the issue I have is monitoring you need a monitor as otherwise you can’t easily see in the LCD when you drop it down I am still working on it but for majority of shots is handheld Sent from my iPhone using Tapatalk
  25. It is effective however if the fish moves you need to lift it as it can't pan. Because you want it to be stable the set up is very negative so when you get an octopus it becomes really hard to track I tend to use it only when I am absolutely certain I will have lots of frogfish and static life and sandy / flat bottoms when this is allowed by regulations
