GH1 Action Short / Field Test

And post a clip if you can, if you pan too fast or are shooting with too high of a shutterspeed you're not going to get smooth movements.

Look closely at those histograms. There are differences. They are slight, but there are differences.

EDIT: And like a side, if I couldn't look at them side by side I wouldn't have noticed, but I do see a difference and from Kholi's response it sounds like I'm not the only one.

Sorry but this is an illusion. You can place those two still images on a timeline and toggle between them like a hundred times and you will not see any difference in contrast. Even if the histograms show slightest differences it doesn't mean it would turn out that dramatically in the final image.

If ProRes would alter color/contrast in a visible way it would be almost useless for practical use.

Ken how are you removing pulldown?

No Jack, not removing pulldown at all, played either straight from the camera or by taking the chip and placing it in a PS3 and playing it directly to my plasma that way. In both cases it's straight HDMI out...no editing. Are you saying that posted 1080p clips would also have stutter if they were native clips straight from the cam?

To address Isaac's post, the clip I posted showed very significant motion on the train as the guy was shooting. So it doesn't seem to be a case of 'too rapid motion'. I tend to pan slowly, but whenever there's a subject with significant movement (car, etc.) you can see the stutter.

So does that mean if you do remove pulldown (something I've never done in my editing program, since I've never had a need to), you can get smooth motion from 24p?
 
As long as this thread has turned into a "which intermediate codec is best" discussion, let me just throw in:

If you like to do complex sound editing in Audition 2 or 3 - Cineform won't work. You get no video preview. And things aren't much better in (the vastly inferior) Adobe Soundbooth, where Cineform codec files will play about 3 frames before video freezes and stops updating.

So far, Cineform is the only codec I've ever encountered this with.
 
There's two things you have to do. 1) Pulldown, and 2) make sure whatever method you're using is also properly reconstructing the interlaced chroma, this is where software like Voltaic and NeoScene come in handy. I don't fully grasp the chroma reconstruction - maybe Isaac or Barry will pop in and enlighten us.
 
Thanks Jack. Now only to find where the 'pulldown' option in Edius is located. Does an option like this tend to go under other names in different editing programs?
 
Wow, this footage looks great. I was all ready to get me an HPX and use my M2, but this little camera's footage just looks better imho. And I can get rid of that clunky M2 adapter. Thanks for doing this test Jack, we all really appreciate it.

best,
JP

Basically I shoemounted a GH1 atop a HPX 170, went to an intersection and taped cars crossing (it was just after a speed bump so they're going 10 miles an hour or so). Anway the idea with taping cars crossing the frame is that they move at a constant speed and any breaks in cadence or jerkiness will show.

The results of the test are interesting and it was surprising how the GH1 image held up and in many ways surpassed the 170 for a locked down early evening shot.



So will have that up today (Wednesday) then hopefully get back to finishing the short / implementing the new conversion methods I've learned.

Jack where did you post these tests you did of the GH1 on top of the HPX 170?

WOW, that looks fantastic, great work .
How did you handhold it , pull focus etc...
Cheers

Heh, thanks very much but I think you are too kind. And this is high praise coming from you.

It's not as polished as its coming off I think - basically we tried to control the DOF and for the shots where they are charging the camera we cut just before or just after it goes out of focus. Also it's crazy action so going a bit soft right before a cut is OK for example, maybe adds to it.

It's just the stock lens. We were afraid to trust auto focus, we set the focus as best we could before each scene.

The only gear we used was the Spider Brace

Perfect for such a light camera, a real joy actually. Takes your wrists out of the equation and makes you pivot at the waist to pan so you operate more like with a film camera. It's like holding air.

Awesome!

Hey sorrt Pappas, I'm beat. Will take me twice as long to do it now as if I start fresh tomorrow. It's quite detailed and organized though. Hopefully the effort that went into it / is causing the delay will be apparent - then it'll be time to get back to finishing the fun stuff - the fight. But since we leaped before looking on this one (which was the point, get in their and learn from mistakes - total budget was $8), I needed to do the frame rate conversion tests with teh GH1 on top of the 170 in order to figure out my post processes with the fight scene based on the way I shot.

Miñana gents.

I know the feeling Jack; can't blame you. Sleep is more important then the test results at midnight anyhow.

Lights out!

Midnight for you. 2 Am for Me.
