LUT for changing Rec 709 to look like VLOG

Brian_Siano — Mon, 23 Oct 2017 17:37:17 +0000

I'm working on a project where I have to match some GH4 VLOG footage to that of another, non-VLOG, rec 709 Panasonic camera. It occurred to me that, rather than making the VLOG stuff match the other camera, I could take the rec 709 footage and make it appear more like uncorrected VLOG. This way, I could apply the same LUTs to all of my footage, and it'd roughly match.

I've done a few experiments, and the results are promising. Using curves, I raise the blacks and lower the whites, and make a few other adjustments. When I apply the basic Panasonic VLOG LUT to the footage, it's a fairly close match. But I'd really like a LUT that does this.

Are there any LUTs that reduce Rec 709 footage to something that's fairly close to uncorrected VLOG footage?

REC 2020 - Finally, REC 709 is getting the boot

"People mistakenly call it a color space," Griffis said. "It's actually a two-dimensional plane and what you really need to know if you're a creative is this is your palette of colors but what the horseshoe chart doesn't tell you is how bright each color can get. White will always be the brightest because it's the sum of all three primary colors."

"So we've got this interesting problem that we've lived with for the better part of 60 years where the colors in film go out farther but you can't get as bright and in television there are less colors but you can get brighter," Griffis told Gizmodo. "And the practical consequence of that for the content creator is that the Red Bus of London that looked so great in the movie looks like Campbell's Tomato Soup on the Blu-ray unless someone does something."

So Dolby (who makes the most amazing video monitors) finally did something. And When it hits TVs and Computer monitors... all this REC 709 bullshit can finally fuck off.

I am so damn happy... you don't even know.

GH4 Manual focus being over riden??

Hi all.. the clip below shows several issues I've been facing with the GH4 but mostly focus... Having seen some online tutorials it seems manual focus isn't as simple as you've expect ... The following clip had the camera set up for manual focus but, as you'll see approx 40 secs in it starts to hunt for focus (but only then!)..... am I missing something in the menu? I can't explain this ... I've checked and the button at the back was set to MF, although in the menu AFS/AFF is set to AFS and continuous AF is set to on (surely MF on the back overrides all this??)...... as the video shows the subject hardly moved and I never touched the focus ring ... re audio on the video, I'm waiting for the musician to supply a clean audio track!

Also I'd love some input from others on colours and noise ... This was shot using a cinelike D mode with everything set to 0 and edited in Prem Pro 2014 , If memory serves I was on 800 ASA which is high but I expected better results for the noise ... The "black" bars are not the same black as the black surrounding them on my monitor... I output the clip using the factory preset for Vimeo which presumably is RGB as opposed to 709, so surely the black bars should match the black on my screen?? (the bars are a shade lighter)

Aside from the focus issue I'd be very grateful for comments / advice / guidance on noise especially in the blacks which are always a bit crappy ..

Thanks

Alan
