GH4 GH4 V-log?

This better not be true. I don't have a problem with a paid upgrade to V-Log L, but not if they are stripping it of potential dynamic range increases.

quoted from the site:
You’ve been hearing that you can get an extra stop or 2 of dynamic range with the new V Log L color profile on the GH4. That may be true. However, my source says that they are holding back. The broadcast division of Panasonic is forcing them to dial it back. Apparently you would get 2 more stops of dynamic range out of the V Log if it weren’t a V Log L (lite). But the broadcast division is forcing the LUMIX divisions hand to tone down the V Log to a Lite version. Also this source tells me that they will be charging $100 for the firmware update.

It threatens that current m43 interchangeable lens 4K professional camcorder they have in the $2000-$50000 price range.

Oh, wait...

Might eat into the sales of the Varicam 35 (which has V-log) would be my guess. But that's stupid, zero sum thinking.
 
Log modes can't give you more latitude than the sensor can actually output. DxOMark lists the GH4 sensor as having a maximum latitude (in RAW stills mode) of 12.8 stops, and good luck getting all of that to fit well into a 100Mbps, 8-Bit, 4:2:0, Long-GOP H.264 file. The 10-bit HDMI out could do it properly though.
 
They've publicly stated V-LOG-L will be 12 stops already at NAB - can't see them backtracking now.

The Lumix guy was praising the Varicam division for their help on the V-LOG-L. I think a lot of people are adding 1 and 1 and getting 3....

It will be 12 Stops, it will be noisy, and it will no doubt be a $200 upgrade fee.
 
Is it me or does the V-Log footage that has been posted still look like sharp as a tack video & does not come close to "film like" bmcc footage.

Poor grading on the testers part I hope.

We will see.

Broadcast can't "force" Consumer to do anything. Please, for the love of all that is holy, everyone quit reading those confounded rumor sites. They are NOT accurate, as definitively proven this last NAB by their "hot" FT5 rumors of a 16-stop M43 camera being proven to be absolute hogwash.

Consumer is the far bigger company over Broadcast. Consumer can do whatever the hell they want, and Broadcast can't say "boo" about it.

If these "sources" knew anything, they'd know that a bigger camera with two processors can just plain "do more" than a smaller camera with one processor. If there's any reason for differentiation between "VLog" and "VLog-L", then that would be my guess as to why.

Which is why it isn't true. There aren't all that many shooters out there looking for a $65,000 camera who think "oh, wait, I'll just go buy a $1500 DSLR." The markets do not overlap, at all.

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.
