In Topic: IS IT WORTH IT? GH5s - No Stabilization

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.

EvilOtter, I gave my editing another try using the Davinci Resolve waveforms, much better results.  Now that I have a wide angle lens I will likely not be using a red filter anymore.  Here is a clip of what the manual white balance can do:




You should still use red filter and custom WB up to 85 ft (depend on visibility). In your clip, the graded clip has almost purple water. I shoot with LX100, if you use the "Scenery" color profile, the blue is much better in that profile.

In Topic: GH5 tripod leg suggestions

16 January 2018 - 07:33 AM




Great solution! Got a parts list???


They stop selling the tripod I used, and it's very old, but I found something that should work. This is it:




In the 2nd picture of the tripod, you can see the "tap"/cap next to the level bubble, once you take apart the tripod leg, that hole is where you would put stainless steel screw through to secure the instamorph.


You would need 3 of this:



Then a small amount of "Instamorph", and 3 stainless steel 1/4-20 threaded screw and nuts, the length of the screw shouldn't be too much longer than the width of the tripod top.



High level instruction:

1.) Take apart the tripod leg

2.) unscrew the hotshoes ball adapter

2.) prepare instamorph,

3.) mold the instamorph into a flatten oval, push the threaded square hotshoe thing through the middle of the flatten oval, push the instamorph to cover the square base

4.) quickly fold both end of the flatten oval over the tripod leg, use a screw driver to pierce through the instamorph where the holes are, insert the stainless screw and tighten the other end with the nuts.

5.) screw the ball adapter back on the hotshoes square to create an indent, and for the instamorph to "grab" the ball adapter.

6.) keep morphing the instamorph until it's fully enclose the tripod leg plastic top section and won't vibrate.


Every few minutes I had to dip the instamorph into hot water to keep it soft.


I'm sure if someone has a 3D printer, it might be easier, but I think the instamorph is stronger than 3D printed plastic.


Let me know if the instruction is not clear enough, if there is enough request, I can do more close up picture of the tripod leg and put into the DIY section of the forum.

The embedded video is too small to see.

U can't really output in 4k if you want to stabilize your footage tho.
I can definitely see many people getting both the 5 and 5s and using the 5s for the deep dives.

You can output in 4K after stabilize, it's just that your pixel is no longer 1:1, in a sense you loose some sharpness. Same happen for NeatVideo noise clean up, even though the pixel may be 1:1 after NeatVideo processing, but you also loose sharpness since NeatVideo introduce some "Softening" to reduce the noise.


From my experience, the stabilized "4K" sharpness is still acceptable for web and home 4K TV despite you could loose up to 5% of the pixel from stabilization post processing. I don't know if there is a big difference in sharpness for 4K shoot from M4/3 sensor (GH4/GH5/LX100) compare to 1" Sensor (LX10, Sony RX100), I suspect smaller sensor could be less forgiving.
