Zacuto Shootout (GH1 specific)

Well, when Philip Bloom answers the 4 commenters on his website and all the stuff on his facebook pages asking which settings he used on the GH1 we will then know.

My point is that I can look at that scene and suspect the settings were not quite right for the GH1, because I've shot with the 5D and I've seen what happens when the settings are optimized for low contrast, and I've done the same with the GH1.

That said did anybody else think the GH1 stuff looked gorgeous on the tub scene?

As for the lightbulb? On a fixed tripod shot like that using any of the cameras I find the look somewhat unacceptable. I would shoot the scene twice, one stopped way down, and comp the lightbulb in :D Boom! Dynamic range :)

Also I'm not quite sure what the heck was going on with the chart. On the Gh1 it looked out of focus, it was askew, all kinds of weird stuff was going on. This is after all the comments about how sharp the GH1 is.

Other question: since when is sharpness a bad thing? Still photography people are always complaining about how digital isn't sharp enough! Film is sharp! The idea that turning down sharpness to avoid false detail has already been somewhat disproven with the GH1. The GH1's downsampling doesn't exhibit the same kind of aliasing and moire problems of the Canons, and turning up sharpness at least +1 on the GH1 is typically prudent: the theory being that by introducing a bit more detail to a scene, the codec can better track changes in areas that it normally wouldn't see changes. IE: a seagul walks away, and with sharpness turned down becomes a grey piece of mud because the codec doesn't see a change, but with sharpness turned up the codec notices the difference, realizes that there are feathers, and details, and records it.

Ben,

Regarding sharpness and the GH1, I have to disagree (in a friendly way as I respect your knowledge and ability with the GH1). In my experience with the camera, setting the sharpness to +1 can be unflattering to faces when you're shooting narrative projects with actors. I suppose for wider shots where a high resolution look is the point, sharpness can help. But, from a layman's point of view, I'm not sure sharpness helps the codec. My understanding is that more detail in an image actually taxes the codec more since it its variable bit rate. If the codec has more things to keep track of, more detail to represent, that's when it chokes and you get mud. If you have a simpler image, it stays below the threshold and the image looks great. That's been my experience with it.

The chart test was actually weird. Gh1 was out of focus and just had an awful image to it. I wonder if they made a mistake, but they took time to edit the footage... Wouldn't they have noticed? Weird.

Steve Weiss asnwered my question on this at the zacuto page: "That's because the close focus on that camera was an issue to match the other cameras but it has no effect over seeing the steps."
 
after watching this for myself, I'd say that they didn't *really* go into this looking to slam the GH1, but they certainly didn't try to improve it's standing either, aside from Mr. Bloom mentioning that they didn't do any real setting changes(as we all know need to be done with this camera).

It's obvious they had certain fixed ideals when starting this *test*. I think that the price point of each camera would determine the outcome in their minds.

I also agree that there was something not right about that GH1 chart. Maybe the way it looked was an artifact of the web compression but it looked BAD. It not only looked crooked, it looked poorly focused as well. Maybe it's my penchant for believing conspiracy theories but based on how that bathtub scene looked I would expect the GH1 to have looked much better than it did on the chart they flashed up for like 1 second.

We'll see if they get to some trumpet charts and such soon. I hope they do because I'm interested to see how their charts hold up to Barry's charts.

Is the GH1 variable bit rate?

Subject change: I haven't seen the Zacuto test yet, but based on comments I've seen here by respected peers like Ben B. and others, I think I smell a rat. Hopefully it's just the APPEARANCE of impropriety.
 
I have my doubts

I have my doubts

too about their motivation with throwing in the GH1, am not impressed, either with their approach or their motivation. As I said earlier these are pro's and they should act like it.
 
FROM PHILIP BLOOM: Please reply from me as not got access to net.
GH1 was not set to either of the ones you state. It was set to the flattest softest settings that you can get with the camera.. Everything you are seeing has been colour timed to its optimal look. Everything from the film to the GH1. Although I have little experience with the Nikons I asked a number of very experienced D3s shooters for the optimum settings. These are what I set the camera to.

from zacuto.com comments.
 
Cool.... Next time I deliver my work to a client I'll be sure to check with them to be sure that they didn't have someone shooting alongside myself with a 5DMKII so they can't compare pixel for pixel the differences.

Sheesh... They all shoot incredible footage.
 
I just went out for a commercial shoot the other day with my GH1...and I was just thinking how much more of a range the footage seems to have (compared to every other dslr I have owned).

from zacuto.com comments.

At 14:58 in the shootout video, immediately following the colorist's "baked-in look" comment, Phillip Bloom says: "I think a lot of that gets down to the fact that we were really not able to tweak [the GH1's] profile to its optimum level, which is what we were doing with the other cameras".

This comment strikes me as really odd. My question is, given all the resources & manpower they had available before & during the shootout, "Why not?"

Meanwhile, is it now safe for me to start investing in fast lenses for use with my GH1? :happy:

Update.!!

Just watched these clips btw, my goodness the GH1 looks the best!! by a long way on the low ISO's. If they had used an equivalent fov,.


My favorite line is " Everyone thinks the GH1 looks great.....But. " Well if that acute group of "eye's" think that; doesn't that say something? However the "but" word followed....

Also there was a mention how grain-less the GH1 footage looked. Then the clip insert following that has someone say " It has the baked in look"...... Well if you use the GH1 right, you can navigate away from the "baked in look".... To bad Panasonic doesn't have their own PB on their side.... He could have been there to make sure they switched it out of "baked in mode" LOL........

Btw, if you notice the Skywalker ( i believe that was the screen in the clip ) where they cut to the GH1 footage, and everyone sounded taken back how sharp it was; and you can tell that from the web video as well how sharp it looked. "But"..................... :-)

Why is it that in these "shoot outs" people shoot Panasonic cameras at the default with out setting up the adjustments correctly,


Actually way back, it was the reverse with the video camera's. Canon always got the " no attention" and Panasonic got the better adjustments. This used to piss off everyone. It seems to have reversed. I think it sucks either way. Panasonic is to blame. They threw their child out, to defend for its self, and never gave it any support. While Canon ( kudos to Canon for doing so ) has been behind their product, as well, involved directly with the community of users. Geez, they sent their own T.Smith to this test..

I noticed this too! ( out o focus, and off axis ). WTF....

It looked like a last minute setup that went something like:

"ooops"

" oops what?"

we forgot to do the GH1 lattitude shot" ...

" yeah, your right".....

"hmmm"

" Hey grab that office lamp and gaffer that board up against the wall real quick, so we can get to the bar with the others"

" is this fair"

" Ahhhh, no one gives a shite anyhow"
