Yokohama in 8K – A Panasonic GH5 6K Photo Mode Anamorphic Exercise

Becoming impatient waiting for Panasonic to release the firmware update with full resolution Anamorphic mode, I decided to take Friday off and try to get some good shots around Yokohama using the 6K Photo mode. It didn’t end up going as planned, but I decided to upload a few shots anyway.

In order, the shots were filmed at Yamashita Park, Osanbashi Pier, the Landmark Tower Sky Garden Observatory, and Ishikawacho Chinatown.

As luck would have it, it ended up being one of the hottest, or the hottest days of the summer. It made it hard to move around, focus (mind and lens), and it was really hazy overall. Not ideal conditions when trying to get your best shots. I think many of them came out great, but double focusing the Ultra Star got tedious when every shot was so different. I had issues with vignetting that I couldn’t see because it was so bright out. I wanted a good variety of shots, but I also knew I couldn’t do a long video. 8K is a pain in the ass to render and the file sizes are huge.

I kept my gear light, using a video tripod, rails, and external mic. I had originally planned to do 5.1 surround audio, but my mic setup failed for whatever reason. I apologize for the on camera audio. I was filming with the GH5, the Panasonic 45-175mm f/4-5.6 lens, and the Chinatown shots were done with the Panasonic Leica 42.5mm f/1.2. Most of the early shots were done with a variable ND, and the shots inside the Landmark Tower observatory were with a CPL.  Any landscape shots were done at f/8, closeups at f/4, and all night shots were done at whatever f-stop to keep the shutter speed at 50, about f/2.0-3. I used 1+ and 3+ diopters for close shots.

Yamashita Park had lots of great places to film. I will definitely go back when I have the chance. And yes, All Star by Smash Mouth suddenly started playing while filming. They also played I Try by Macy Gray, making me think that the park’s music CD was from 1999.

Osanbashi Pier apparently shakes just enough to not be compensated by Dual IS. It was constant the entire shoot but I didn’t notice until I got home to check the shots. After Effects Warp Stabilizer did a good job eliminating it, but had I known I would have done the shots handheld.

Landmark Tower’s Sky Garden was great. It cost 1,000 yen just to enter, but they had no issues with me using a tripod. (Many Japanese tourist sites don’t allow them) The glass reflection, however, was really difficult to deal with, even with a CPL. I couldn’t get the lens close enough to the glass to eliminate it, and the glass is so thick/layered that even then there were still reflections. Some of the shots I took with my iPhone right up against the glass had reflections.

The shots in Chinatown came out great. I would have filmed more but I was already super tired by that point. I also had limitations, as if I wasn’t careful I got heavy vignetting with the Isco Ultra Star and the 42.5mm lens. I need a bigger variable ND if I’m going to use that setup. I tried to film a guy making candy, but his lights were so bright that I had to stop down to f/5.0, and it gave ugly dark corners.

 

The next challenge was working with the damn H.265 files. I repackaged them in Handbrake (who decided to change the dimentions on a few videos for no reason), and they worked OK in Adobe Premier. I have a pretty fast computer that can handle 4K stuff with zero issues. But it was like I was in 2008 with HD files on a 2006 computer. Press space bar, wait 5 seconds, it plays. The edit took far longer than it should have. And that was after rendering all the shots at 1/8 resolution. The rest was no-nonsense, I imported it into After Effects for color correction (something I am still not good at) and then it came time to render.

After researching if there was a better way to render 8K video and failing in all attempts, I decided to try just slightly reduced settings from my early experiment that I rendered using GoPro Cineform and just hoped the file would be under 128 GB.

After 3 hours of rendering, I was left with a 3 minute and 19 second,  42 GB large, 9984×3744 sized video. I’m listing it as 8K, as Youtube will only support up to 8K right now.

Overall, I guess I’m happy with it. I think the shots could be cleaner. I think if I brought more gear and my square ND set I could have got better overall compositions. Double focusing is not an ideal process for getting perfect shots on the fly, and some of them are not as clean as I’d like. When Panasonic offers the full resolution 6K Anamorphic mode, hopefully it won’t be in that god-awful H.265 format. Until then, I think I’m done with the 6K Photo mode.

I need to get more hard drive space. This is going to be a data nightmare year.

The GH5 Era Begins and the Start of Lots of Updates

So, after a deal with a very dangerous group of individuals, I have finally acquired a GH5. This wasn’t planned to happen for a few more months, maybe even a year… but hey… GH5.

Not having a GH5 is not the reason for the lack of updates. I was very sick over the past few months. Last year a had a bout with vertigo that came back with a vengeance this year. Makes it hard to focus on anything. This was compounded by a list of other problems I won’t mention here. I am much better now. That’s all that matters.

I will go more in depth into GH5 ownership as I go down the road. For now, let’s talk about the two videos I posted recently.

One of the huge differences between the G7 and the GH5 is the 6K photo mode uses the actual full sensor, where the 4K photo mode on the G7 did not. Another big difference is the use of H.265 for these video files, which are a pain in the ass to deal with. However, once the files are properly re-wrapped in Handbrake, you get a massive 4992×3744 video file. When doing my first batch of tests on the first sunny day in awhile (the weather has been horrible since I got the GH5, pushing back planned videos) I shot a few “6K” videos.  Of course I had to do it with an anamorphic attached. After all was said and done I had 20 seconds of 9984×3744 pixels at 14.1 GB.  The only codec that seemed to be able to handle it in Adobe Media Encoder was the GoPro Cineform RGB 12-bit preset. I was using the Isco Ultra Star and the Panasonic 45-175mm zoom, a combination I use for no-nonsense sharp images. It was a successful test, but I think I can do better. I may clean out my work drive and try a short edit of sorts to see how far I can push it. I may even get out the Zoom H2 and do 5.1 surround audio too. Wow.

On to the next…

I picked up a copy of the Möller Anamorphot 32/2x awhile ago, but didn’t get much of a chance to shoot with it. This is a very special lens. I wanted one after hearing you could just screw a 40.5mm step ring on the front and use it as/is. Well, this was the start of a few issues I had with mine. To keep it short, I ended up having to file down the inside of the step-ring to get it to fit right, and even then it took awhile for me to get the confidence to put anything on the step ring. Unfortunately, it doesn’t work to well with the Aivascope Focuser 8. It’s just a bit too long. It does, however, work perfectly with my set of 52mm Nikon diopters. The filter ring also doesn’t rotate when you are focusing, a rarity among anamorphic projection lenses. If you get the custom Redstan clamp for it, it’s a completely trouble-free lens and is incredibly easy to use.

The above video was shot entirely at f/1.4 and double focus. You can use it at 1.2 as well, but my only 1.2 lens is too wide to use the Möller in Anamorphic mode. It’s such a sharp lens… just unbelievably impressive. I am, however, lucky that I can even use it in this state.

When I was cleaning up the lens and getting ready to black out the edges, I had the filter ring completely removed to get at the edges better with my paint marker. However, the lens was set at infinity. And with the top lock collar also removed, a bit of pressure on the top of the lens pushed down the focusing part and the front element…. popped up. It was a nightmare getting it aligned properly again. But as you can see above, I did eventually get it right.

Lastly… having 60fps at 4K is pretty amazing. I will thoroughly abuse this feature. I will also have fun with the other high frame rates… but I already hit a roadblock with those. More on that later!
