#361311 Warna berwarna Raja Ampat by GH4

Posted by kc_moses on 19 May 2015 - 09:32 AM

Finally! There is another 4K diving video!!!! I was just wondering, there are so many GH4 shooters out there but I only saw EJ from Korea upload video in 4K. I guess you have been missing in action. The song is catchy, anyway you can add some tambourine track because it could really use one.

Are you comparing GH2 ISO 1000 with GH4 ISO800? I suggest you go find some ISO 800 4K underwater clip shot by GH4 and check out the noise (watch it in 4K monitor so you get the 1:1 result)

 

kkfok and I both confirmed that shooting 4K at ISO800 will have more noise, we both use LX100, I have shot with GH4 and it's the same problem:

The Ursa Mini is not the NEXT big thing, it's only months away, I'm not talking about GH5. My reply simply imply that RAW footage grade better then 10 bit 4:2:2 and the Ursa has it.

 

Bottom line if you're getting the result that you're happy with, just stick with what you have.

 

Also, check this out in term of 10 bit 4:2:2 vs 8 bit 4:2:0 grading:

 




#360784 Anilao Frogfish in 4K

Posted by kc_moses on 04 May 2015 - 09:06 AM

Thanks! There are a lot of frogfish in Anilao, I believe I saw all the color of frogfish in this trip. I saw the yellow juvenile frogfish but it got spoke back behind/under the rock by the divers before me so I didn't get to shoot it. To answer your question, those tiny little crawling thing are not nudibranch, I believe they're some sort of crab/bug. you can see them at 2:12 of this clip by Chris Parson:

 




#360779 Anilao Frogfish in 4K

Posted by kc_moses on 04 May 2015 - 06:58 AM

Alright, got the frogfish out of the way. I have to say, they're not my cup of tea, but I finally saw hairy frogfish!

 

Finding music for frogfish is tough, shooting them on wall dive is even tougher! I probably should have learn how to use the Zebra feature on my Panasonic LX100, many of these guys are white like a snow ball and being down in at least 40 feet deep, it's hard to keep the surrounding properly expose while not to blow out the white frogfish. I have a couple shot of black frogfish, but they didn't make it into the video because they really look like a clump of charcoal. Anyway, enjoy (Watch in 4K setting even if you don't have 4K monitor just so you can benefit from the extra detail):

 

 

PS: Looking back, I could have shoot the white subject in more flat profile and grade them later. But there is no Cine-D or Cine-V kind of profile in the LX100, will have to research and see how to make one up. Any critique/comment is welcome! I think I got low enough, what other angle would you shoot frogfish at? Didn't see them yawn or snatch a fish up for meal, it's a tricky subject to shoot.




#360590 Does my color right? Nusa Penida WA shoot with GH4

Posted by kc_moses on 28 April 2015 - 07:49 PM

Bona,

 

Did you shoot custom white balance the whole time? The Manta ray clip sure doesn't look like it, while the other clips seems fine in term of coral color, but the blue water is on the purple side, and when looking at the diver's mask band, it appear you took the color too far.




#360480 Nudibranch of Anilao in 4K - Panasonic LX100

Posted by kc_moses on 26 April 2015 - 11:26 AM

It's my first time shooting with the Panasonic LX100, Nauticam CMC-1, first time to Anilao and second time shooting macro. I'm starting to accept the result especially I only have around 150 dives under my belt. I found that the more dive experience I have, the more comfortable I feel about getting close, slow down to think and adjust my camera setting (not having a big group of divers lining up or selfish dive buddy would help too!

 

I'm starting to get a hang of the editing portion too, music is always hard! Here is the result:

 

 

If you have 1080P display, watch in 1080P setting, then watch again with 4K setting, see if you can see the benefit of 4K. If you have 4K display, then of course watch it in 4K setting.

 

I output my final video to target of 80Mbps. A 8 minutes video is about 4.6Gb, it took about two hours to upload to Youtube and process. It's really hard for countries that do not have fast internet to provide 4K content. I don't know what's the final bitrate that Youtube produce, but if it's buffering right, the Youtube deliver quality is very close to my 4.6Gb mp4 sitting in my local hard drive.

 

Make sure you watch the whole thing!

 

As usual, suggestion, critique, comment are all welcome!

#360415 How important is underwater tripod?

Posted by kc_moses on 23 April 2015 - 06:40 AM

Here is another DIY solution for Macro. I doubt tripod is useful for wide angle, especially on wall dive.

If 5DM4 has 4K, it will kill their XC10 since XC 10 price around 5dM3 or 5dM4, but 5dM4 has full frame sensor, interchangeable lens, takes photo.

 

Just read this: http://www.eoshd.com...with-canon-log/

Nice work as usual Dustin! Like the different view of the plane. May be because I don't have knowledge of the plane, I think it would be nice to have divers around for scale reference? I mean the plane looks really big during the top down view of the plane at 2:45 but I have no idea how big.




#359833 Canon Cinema EOS XC10 4K Camera

Posted by kc_moses on 09 April 2015 - 08:19 AM

 

Not sure what muddled 1080p footage you are referring to, but footage from a 5d II or III isn't muddled.  4k does look nice sampled down to 1080p, but that doesn't make 1080p footage muddled.  To me, color is everything...It's what captivates the viewer, along with the subject being shot.  Detail is nice, but I don't think its lacking by any reasonable camera made in the last 5 years. 

 

 

I'm sorry, I need to clarify that. What I mean muddled is when watching 1080p footage on a 4K monitor. Just like SD/DVD get pixelated when watch back on a 1080p monitor.




#359613 How would you shoot this scene?

Posted by kc_moses on 04 April 2015 - 07:10 AM

Thanks Nick!

 

I had the focus on the sand/burrow in the beginning, so when the eel poke its head out, it was focus. I thought the eel would just stay straight out of its burrow, but whole know it gets so long and dances in between the fish! I have another clip where the focus was on the fishes, I was hoping that when the eel is in the fish area, its head would be in focus together with the fish. Yeah, I swear a lot, not to mention there were lines of diver behind/next to me waiting for their shot.

 

It was definitely and interesting experience, not sure if I will get the chance to see this kind of behavior a lot. Let's hope the next time I would better shot!




#359375 LX100 Underwater Video - Anyone else have experience with the LX100

Posted by kc_moses on 29 March 2015 - 02:11 PM

Here are two screen capture of the LX100 shot with ISO800:

 

Anilao01.jpg

 

Anilao02.jpg

 

The Octopus is night dive, while the Nudibracnch is day time with custom white balance without video light. As you can see ISO800 on the LX100 is usable and pretty good, just not on scene where you have lot of blue color water. The Sipadan LX100 clip posted at the top of this discussion shows very nice/clean  blue, I'm not sure if it's because the diving condition in Sipadan is much better than Anilao, or the fact that the Sipadan clip is 1080 instead of 4K sort of hide the noise at the blue part of the clip.

 

I'm still going through my clips, I have about 800 clips! If I found some that show the water column in ISO400 or ISO200, I will post it here for people to judge/reference.




#359346 LX100 Underwater Video - Anyone else have experience with the LX100

Posted by kc_moses on 28 March 2015 - 08:48 PM

Basil,

 

I used Magic Filter with the LX100 during my recent Anilao trip. I have an extra 2x2" Magic Filter from a while back when I bought a pack of three. The 2x2" is more than enough to cut to size and stick on top the lens before putting the camera into the housing. You do loose a bit of light, but it won't be a problem in tropical water. The weather condition in Anilao turned cloudy so I stopped using it after 1 day.

 

Here is the screen capture of the dive when I used the Magic Filter + Custom White Balance:

MagicFilter.jpg?psid=1

 

The dive was in the morning around 9 am. I shoot the video in Manual mode, Shutter: 1/60, ISO 800, either F8 of F11 (I don't remember). To get the best result out of Magic Filter, the sun should be behind the shooter. I have to say, Anilao is not a good place to shoot wide angle video because the water just have too much sand/murky. There were a lot of traffic in the area so the sand could be caused by diver stir up sand as well. I was with a group of U/W photography, they had workshop so in mid trip everybody switch to WA and I'm stuck with them. Feel like I just joined a group of people travel to Asia to eat McDonald.......I wanted more macro dives!!!!!

 

Moses

 

PS: ISO 800 is too noisy for WA, ISO400 is the max I would go if you have a lot of blue color water to show in your composition. I used higher F-stop because I wanted more flat depth of field, and paid the price of needing to use high ISO. Good thing the LX100 can open up to 1.7F so that's not an issue, I would choose low noise video over flat depth of field from now on.




#358025 GH4 - Nauticam Macro Lens/Port Thoughts

Posted by kc_moses on 18 February 2015 - 02:04 PM

Well, from my experience, the manual focus would be handy. Say if you shoot at Manual Focus mode, you use the back button to set initial focus, and shoot the nudibranch. As it craw toward the screen, you have to pick up the camera and move backward, or use the back button focus technique to refocus again. But if you have a manual focus knob, you can actually "pull focus" and smoothly adjust the focus. I found that using the back button to re-focus a subject that just moved would give the effect as if the camera is focus hunting.

 

Sometimes when you use the back button focus, it might just focus on the face (like the seahorse), but the eyes is not that focus, just the snout of the seahorse is sharp. This is when it would be nice to have the focus knob to bring up the enlarge screen and really focus on the eye especially with the help of peaking. I don't use pinpoint focus so this is the way I did when I test out the GH4.

Reef Photos came through again, and I will be receiving the 1st production unit CMC-1 in the US, just in time for my Asia trip, flying out in 5 days!!!!!  Looks like I will leave my Aquako IV in my spare diving bin at home and use it for something like a GH5 in the future.
