Panasonic Announce V-Log for the GH4

Finally Varicam LOG lite for the GH4 is announced. 12 full stops of dynamic range and accurate color reproduction. Available for pre-order now, will ship around the middle of September.

"In response to the demand from the film production market, log video recording (V-Log L) is now available for the LUMIX GH4, and offers exceptional flexibility as well as wider dynamic range for color grading in post-production process. V-Log / V-Log L were developed to feature similar characteristics to Cineon, which is a characteristic curve for film digitization. Taking full advantage of Four Thirds sensor, V-Log L boasts a log characteristic with 12 stops. Both V-Log and V-Log L have the same characteristic curve, and the same LUT (Look Up Table) can be utilized."

It's about time, I've been waiting for a log profile forever.

Hey Guy,
Do you not find it odd that Panasonic wants $100?

>>>Do you not find it odd that Panasonic wants $100?

No. This is a new feature for the GH4 that was never promised or talked about when the GH4 first came on the market. I think most professionals and advanced amateurs won't mind paying the $100 for this new feature. And being a paid upgrade it will also help keep it out of the hands of the "newbies" who will have no clue as to what V-log is or how to process it in post. ( explaining V-log to a "newbie" would be a tech support nightmare )

V-Log for the GH4 is a 12 F-stop subset of the 16 F-stop Varicam LOG format from the $60,000 Panasonic Varicam 35 camera, and the LUTs will be identical for both cameras. From the tests I've seen so far, GH4 V-log produces better color ( especially skin tones ) than the Sony S-log2 profile.

There's an interesting technical discussion on how to properly expose GH4 V-log ( V-log on the new Panasonic DVX200 ENG camera is the same as V-log on the GH4 ), that includes a graph showing how GH4 V-log compares with the $60,000 Varicam 35 LOG, by Barry Green on the DvxUser website.

I know that Samsung added LOG profiles to their NX1 camera for free, but they are trying to establish their market share and are doing everything they can to get people to buy their camera. ( I don't think Sony has ever added a free LOG upgrade to one of their cameras that did not have LOG from the start )

Also, Panasonic will start selling a GH4R camera ( GH4 Revised ? ) that will ship with V-log already installed. Most likely this camera will cost $100 more. ( I am wondering if this is going to replace the previous GH4, so that every future GH4 sold will have V-log installed )

Great answer Guy! Sony charged $400 to add S-Log on cameras that didn't have log yet, such as the PMW-F3. I think this price is quite a steal. It adds a lot of value to the camera and future proofs it just a bit more until every camera is 4k and above. And I'm sure in the near future, log will start being standard on these types of cameras.

Oh yeah, I forgot, and my friend here said prices went up to $899 for log upgrades in some other Sony's. I think my point is, $100 ain't nothing for all the other people griping up a paid upgrade.

Actually, Sony originally wanted $3,000 for the firmware upgrade that would add S-log to the PMW-F3, and the price kept dropping because of competition from the new ( at the time ) Canon C300, until in the end Sony was giving S-log away for free.

...And now you can buy a brand new Sony PMW-F3 for $3,995 from B&H Photo that includes the free S-log feature.

I just read that another feature of the GH4R will be unlimited recording time. That's not useful to me because I get that with a SHOGUN external recorder (with 4:2:2 10-bit to boot), but it does mean the item will be taxed as a video camera, effectively increasing its cost to Panasonic. So it creates an opportunity to keep the original price intact while offering a bit more value, rather than continuing to discount (such as we're seeing with Canon 5D3 and 1DX).

Just noticed on Wex Photographic website the GH4R is listed at £1,199 (think the original launch of the GH4 was around £1,300ish? from memory). So not too bad, however those with external recorders already, Panasonic it seems are offering cash back deals (again at Wex Photographic) on the original GH4. £200 cashback + £50 off using their code. Essentially one could pickup the original GH4 for £750 brand spanking new with a 5 year warranty, though most would have moved onto a new camera within that time frame :)

No idea how painful the cash back scenario is though!

I will be getting the V-Log update for my GH4. I think 100$ is a very acceptable price for adding 2 stops to my camera. I do wonder about how much more difficult it will be to do proper lighting (you can't use your histogram in the same fashion as before) and grading will be quite different as well.

It's going to be a little bit of learning curve with this new GH4 feature. There is probably a way to set your GH4 zebras so that they they indicate when you are close to reaching 79 IRE, which also might help.

I have a few light meters ( including a digital cine-meter ) which I'm going to try and use for correct V-log exposure. I'm sure one way or another we will all figure this thing out.
