Yeah Red hair, Pink flowers, Pale skin, not a easy grade. I would err that way also I believe. :fearful:

But, ehh, but I think those are Suppose to be White flowers under her chin?

I thought the same as you, but I believe they are pink flowers. And her face is merely reflecting the pink light from them. So it may be that a secondary color correction would be needed to correct for her face. But if she isn't sitting still, it wouldn't be necessary. So that's another danger of just looking at a screen grab from a moving image.

Well we will never know for sure, and yep taking one frame from a whole damn video and examining it as a whole is pretty crazy I will admit.

But it bought back some funny memories, and that was worth it. It was a fun crew I worked with, and overall a damn talented group of people. Some were scary talented!

Either way she is a beautiful women, and that comes across in the grade.

Webrunner ... I believe the article http://www.xdcam-user.com/2013/03/to-shoot-flat-or-not-to-shoot-flat/ is still relevant, especially when considering relatively small sensor cameras such as MFT.

Extract from main article ...
"When you use a high compression codec it adds noise to the image, this is in addition to any sensor noise etc. If you create a look in camera, the additional compression noise is added after the look has been created. As the look has been set, the compression noise is not really going to change as you won’t be making big changes to the image. But if you shoot flat, when you start manipulating the image the compression noise gets pushed, shoved and stretched, this can lead to degradation of the image compared to creating the look in camera. In addition you need more data to record a bigger dynamic range, so a very flat (wide dynamic range) image may be pushing the codec very hard resulting in even more compression noise and artefacts."

I suspect this can explain somewhat the poor GH5 results in camera with 4K 10 bit 422 150 Mbps, as reported elsewhere.  Using http://wolfcrow.com/blog/thoughts-on-comparing-8-bit-and-10-bit-footage-from-the-panasonic-gh5/ "Wolfcrow's" articles calculations it's a compression value of 27.14 to 1, very high.

By way of comparison here are some more compression ratio examples from a few popular cameras, not high end cinema cameras ...


Obviously there's more to output than just the compression ratio, some FHD low compression examples below are known to give poor quality, but for other reasons.

All things been equal, which they never are, the lower the compression ration the better.

Any tips on exposing Vlog? Read too much about how to overexpose SLOG, but what's the case with the V-LOG L?

Exposing V Log on the GH5 should be a lot easier than on the GH4. It took me a while to nail the exposure, but i would first look at the exp meter and get it near 0. Block out any super highlighted areas with your finger and look at the meter again. The highlight rolloff is better in V Log than standard so you can expose a bit to the right to avoid shadow noise.

Having a LUT preview for V Log in the GH5 is a huge help. You should be able to eyeball the exposure with no troubles.

@AaronChicago....I remember your early stuff you shot on the GH4 and you seemed to have no problem making beautiful work with it (in VLog!)...I still have one GH2 lol...I love my Gh4's too...never did get the 3 though and excited about 5!

Looks funny when the shutter speed value slot is empty in the most sophisticated Panasonic system camera. It just dont want to tell it.

Even with GH5 we must go to photo mode to find out what the shutter speed may be when starting video.

Thanks man. I think I'm going to trade up for the GH5. I use my UM46K most of the time now but I still love using the GH4 for various shoots.

If you balance off the concrete post on the right, the flowers do seem to be a pale pink.

ANDREW REID: "OK first of all, assuming you might use manual focus sometimes, or often, let’s get that punch-in focus assist working which is absolutely mega on the GH5 – the highest frame rate and resolution I’ve ever seen for a punch-in focus assist."

Do you mean that punch-in focus magnification (aka MF Assist) works on the GH5 WHILE/DURING recording video? The GH5 would be the first Panasonic camera (including expensive dedicated video cameras) that would support this feature. It would be really awesome. So, again, do you say that after you start recording on the GH5, you can activate MF Assist and monitor focus while the camera is recording video? This function is pretty common on all Sony cameras, but not on any other make. 

Thank you so much.

Andrew, can you only load LUTs when shooting in V-Log? Can you load your ProColor LUT when shooting in a baked-in profile?

yes you can only load luts through activated vlog

what settings are people using for auto focus for video?...afs, afc, aff? face recgonition or 255 points

and what about peaking?...peakingset to low or high?

Got the GH5 today!

First shots in 4K 50p look absolutely stunning.

I have also messed around a bit with the VFR. I tried some shots at 180 fps. Very cool. That's like 7.8 times slower than real life isn't it? Quite amazing.

I noticed though that the screen doesn't show the actual exposure before recording in the VFR mode. It shows the image way brighter than it actually is. It's until after you press the record button, that the screen shots the actual exposure.

This doesn't happen in any other recording mode as I have put the option 'constant preview'. Anyone knows if it is possible to change this?
