Released! 4 Panasonic Firmwares; GH5, GH4, and two lenses

[deezid]

Just figured out, the camera still applies sharpening at -5. At least in 4k, although there are way less halo artifacts!
The 6K mode doesn't apply any further crop and looks almost identical to in DR14 decoded DNG from the GH5 (adobe dng converter used) with sharpening set at 0 in RAW decoding panel.

Great news!

IS lock seems to work great for gimbal usage, wouldn't use it handheld though, unless I'm walking.

What would make you choose this over the 4k 60p?..does that extra 50mb and all intra make that much difference to the footage? I cant see myself using 1080p intra when i have the 4k 60p option....

Using V-Log and planning to use HLG, so I need 10 bit.

I can confirm that my normal sandisk UHS-II (not V rated) works without any problems. No stops until the card full.

UHS-I card stopped after 23 seconds.

Also, the AF is veeeeery cool.

Can anyone else tell their experience with UHS II (not V rated) cards?

fair enough, it wasnt a moan...just interested...vlog is pretty bad in 8 bit. As much as the candence of 1080p all-i interests me i cant seem myself sacrificing the 4k resolution and options that that brings with it like post stabilsation and cropping..

That's why I feel like there should be something in between of 1080p and 4K, like 1440p, 2K/2.5K or 2.7K. Gives you more wiggle room for a touch of reframing, fake zoom/slide/tilt and stabilization, might be better quality than FHD when downsampled and allows for higher framerates than 4K.

I actually think the 1080p 50/60p 10bit mode is better than the 4k 50/60p mode. The extra resolution in 4k isn't significant enough.

better in what sense? this is the all-i we are talking about? I do love the extra crop you get in ex-tel mode in 1080p compared to 4k...but again i think i would miss that extra wiggle room for reframing, cropping and stabilsation in post that 4k gives you...

I'm not seeing any difference in motion between ALL I and IPB, so I'll probably be sticking with 4K 150 Mbps.

Had a friend have something a bit odd happen with his GH5, he has two identical Lexar cards, but one does, and the other doesn't work in his GH5!

Is this the 280MB/s card? Thx

Hi

Just because they are identical doesn't mean they are of course.  A lot of manufactures will buy in NAND memory from wherever is cheapest, and even if the same they will be differing quality.  In the same way Intel CPUs are mostly the same with the best off the production line running and sold at higher clock speeds, NAND works in a similar way.  Also as the NAND is used and bad blocks are mapped out, the speed and reliability will vary.  If it works and it isn't a V60/V90 card, it's a lucky find, buying the exact same again you may not be so lucky.

V90 cards are using the cream of NAND memory and a different recording protocol to achieve a guaranteed minimum write speed regardless if the card is fresh out of the packaging or on it's 100 use.  This is why they are more expensive and harder to come by.

Hi

Me neither, and the likely hood of the final output being All-Intra is next to none, even if there was a visible benefit, it wouldn't be delivered that way. 

Also IPB in the GH5 codec isn't really that long of a GOP, as usually just 24 or 60 group of pictures is used in the GH5 for a group, in comparison internet streams or higher compression rates will see 200 or more before a clean I frame.  So cameras like the GH5 don't really suffer from motion issues caused by the compression anyway.

Except you can see it if you look at the individual frames. Of course it's there. The only question is if that distortion is perceptible when playing back at 25fps or whatever.

Huh? Some manufacturers will use the best, others will not be. Some use MLC while Pana uses pSLC in their V90. Sandisk, Panasonic, and Toshiba should be good though, as they invented the SD card association. 

[jonpais]

What I’m most eager to try out is the 72mbps with LongGOP compression 10bit 4:2:0 HEVC

[futur2]

Did anybody try the ADATA Premier ONE cards?

[DBounce]

@futur2 I picked up these. They seem to work without issue. I choose the micro SD version as they will likely be more adaptable in the future (can also work in smartphones, drones etc). Also the construction of the micro SD seems to be more durable. As there is no hit to performance, the micro seemed to be the best option.  

[jonpais]

Smart move, @DBounce. I got one Panasonic 128GB v90 and one Angelbird AV PRO 128GB v90, but now it looks like I won't even be needing them. The single feature I'm most interested in at the moment is HLG. I don't care about editing for now,  just want to be able to shoot and play on TV.

Don't think of these cards as identical, precision parts. It is the opposite.

There is great variability in the manufactured output, and the process deals with yields and salvage. The product labeling is based on what bucket post-production testing puts them in.

The raw product is a commodity, and the quality and quantity of what is available in the marketplace varies. One comment describes a certain memory card seller as using "catch-of-the day".

What I mean is, we might be lucky and have a card that whilst it isn't rated V90, seems to perform okay, we then buy 4 others the same and find they don't work reliably if at all.

If it doesn't have V90 on it's label, then it isn't a V90 card, so whether it works or not is somewhat down to luck of the draw.  The card could also be so borderline, that it will work for the first couple of shoots, then fail consistently on the third.

The only way to have a V90 card is to buy one.  A card that isn't V90 is a different beast and is written too like a file system, whereas a V90 card switches the camera to recording in a more efficient and reliable way, probably why you have to have a least one of these to allow the camera to work fast enough to write a backup to both cards if that mode is selected.

I doubt all V90 cards will be V90. Too easy to add a label. Best to go with a good brand with good QA and memory type.

Don't confuse the arbitrary speed specs that manufacturers put on their cards with the speed class specification from the SD card association. V90 will be V90, otherwise they either wouldn't be able to use that label, or even worse be liable to very expensive lawsuits. Specifying minimum is way more strict than specifying maximum that you probably achieve only in benchmarks  

Now if the card is V90 one day and it stops working the next, thats a whole different matter.

Reality is not black and white (in a manner of speaking). Plus I think you live in a bubble that does not include certain countries. You guys lost the argument with the V2 release, mind as well go back to relaying actual performance with the actual cards you have.
