GH4 GH4 V-log?

Yes but does that mean via HDMI/HD-SDI or when recorded internally to 8 bit as well? I have this suspicious feeling this is a fancy form of CineD that gives the effect of a wider range and grade-ability at the expense of other quality factors. Like others have said it could very well have a lot of noise. I could be wrong since I don't have any experience with any form of V-log but I have used S-log on the SONY F3. To me it seems adding a curve to an 8 bit format is still adding a curve to an 8 bit format no matter how you want to spin it.

Here is an article that talks about using Sony S-log with 8 bit formats and how it may not be the best option. I think V-log can be a great option but I honestly think most will only really see a major benefit by using a 10 bit external recorder. Not a difficult or expensive thing to add anymore if you want HD but can be a bit pricey for 4k. Just something to keep in mind about V-log. While it can and will work with internal recording I think the only way to gain any advantage from it is to record externally. Any other benefit we see online may be more of a placebo effect sort of like how so many gravitated towards CineD thinking flat was better.

As much as I fully agree with you Thomas, I do think there is an upside. Sure, we are limited by the sensor' ability, sure we are limited by 8-bit, but, we might as well use the available tools at hand to fit the spectrum INSIDE the camera's abilities, IF the scene warrants it. If the lights are gonna blow out, or the darks be buried in black, we could use log or cined or contrast to reel it in, and capture more of the scene we wanted. Even with the added noise or banding, it still may be beneficial for that scene. I'll try and use up the whole 0-255 on my camera, but if something is getting chopped off, and I don't want it to, I will try the tool that could bring it back in. Everything is a compromise anyway, make the compromise work for you instead of against you. :)
 
I'm sure many here are prepared, or capable of handling, Log but just as surely many more are not & IF Panasonic releases it on the GH4 the Internet will have a fit over the issues.

Amen.

I've read so much nonsese and FUD about this.

And for the record, DxO can not somhowe know (accurately) the absolute correct theoretical dynamic range of a system that they have not tested. While they may be better than average in testing methodology and transparency, they don't always get the results right.

V log L adds 2 additional stops of dynamic range to the GH4, you can see it with your eyes and it can also be measured.
 
So its June and no word on release date yet. Too bad, really wanting to try this. (Thinking to buy another camera like the ursa mini, but want to try this before buying something else)

Same here, I'm really excited about the Ursa Mini 4.6k. 15 stops sounds nothing but impressive!
With V-Log we would get about 12 usable stops, which isn't bad either. But when??
 
Yep...I am of the same mindset, V-Log is seeming like vaporware to me...plenty of rumors, plenty of "it will be coming" in the meantime while this rumor has been circulating BMD have built some impressive sounding new cameras like the Ursa Mini..made some solid updates on their older cameras and Samsung has done several firmware updates...and still no V-Log for the GH4.
Sadly Panasonic just is not happening with this so called Firmware update, (Maybe they should let Vitaliy hack it LOL!! that gave the Gh2 an extended life...Anyway I'll be checking out the new BMD stuff when it comes out for sure.

A GH3 hack is more vaporware than V-log. Vitaliy has been trying to hack it for 2 years (or at least collected donations for the effort) ... so, I'd say don't hold your breath on a GH4 hack. ;)

Has anybody else looked at the Blackmagic website marketing photos and felt that they are marketing to an under 25 year old crowd?

Not a fan of BlackMagic's marketing but at least it's not as bad as the old "Zacuto Girls" cheesecake campaigns.

On paper the Mini 4.6k seems impressive, but needs to be field proven. Just the lack of a protective door over the CFast Cards gives me pause, as does BlackMagic's overall track record.

Just picked up an FS7 to hold me over until the C300 II, & Mini 4.6k, have proven themselves & only then will decide to adopt or not. I'm still a fan of the GH4 for some projects, but need a more complete package for others.

Yep agreed, Vitaliy wont be hacking the GH4...thats for sure, what I meant was Panasonic may keep the value of the GH4 alive for a lot longer by giving Vitaliy the details how to get inside the firmware, but of course they wont do that,
and he certainly wont be able to do it by himself.
So that leaves it up to Panasonic...so yeah I am not holding my breath on anything really, just shooting vids and developing my skills.
I still love the GH4 ...but I will definitely think twice about buying another Panasonic in the future, simply because its becoming increasingly apparent that they are a typical slow Japanese Manufacturer that cannot move at the
speed of some of these newer companies that dont have the lead weight bureaucracy that Panansonic, Canon etc...appear to have.
 
I think Panasonic made too much noise at NAB with the public showing of V-LOG-L.

Can't see how they can't release it now, saying that - could be saving for the GH5 ('alas after extensive testing the Venus engine in the GH4 couldn't blah blah, but the GH5 can...'

Right?? They basically promised V-Log for the GH4. I really don't understand how they could back off of that now. The Camera Store posted a video of their test run with V-Log-L on the GH4...Why go as far as giving out a pre-production version for review if they had no intention of actually releasing it?
 
Yeah exactly - they have released too much, to too many people - can't see them not bringing it out now. But it has gone very quiet....
 
I was at Cinegear earlier today and every single GH4 they had on the floor was displaying V-LOG L on it. I didn't get a time frame for the release but there's NO WAY they're not releasing it. It would be completely disingenuous at this point.
