Here are a few HD100 frame grabs (jpg) from some footage I took in Apache Junction AZ. This is straight off of the camera.

Can you share your settings?

Great looking stuff Steven.

Steven Thomas · March 1st, 2006, 11:48 AM

Thanks,

I used Paolo's DSC settings listed at the bottom of his webpage.

You may want to change Knee to 80% and Black stretch to 3 as reccomended by Tim Dashwood to render the most latitude.
Nate Weaver also recommends this change.

I bet if I had the knee and black stretch set as mentioned, the footage would look even better.

Well, there's always next time :)

The footage looks pretty good. I especially like "relaxed.jpg."

Setting the knee lower would have helped you control the clipped highlights the one cowboy's white shirt in "more.jpg"
Setting the black stretch to 3 would have rendered more detail in the shadow area of "dress.jpg" where the cowboy hat is hung on the wall and on the bearded cowboy's face. A lower knee would have also avoided the clipping on the cowgirl's shirt.

The colour redition looks good and your exposure was spot on.

was this captured live uncompressed or did you filter the chroma channels? They look pretty smooth inside of Shake.

That's the way the channels separate from the ProHD source Thomas. Blue, Green and Luminance are immaculate and Red is slighly over exposed (most of the time. That encoder has incredible quality.

Tim,
thanks, I saw those same issues and sure wish I has set the black stretch and knee to allow for more dynamic range. Live and learn..

Thomas, JVC HDV codec is really decent. I can't believe how good this stuff looks on my 50" Pioneer plasma. The image is very filmic and clean.

Tim, Nate, and Stephen woke me up to how well the HD100 performs.
I'm sold on the HD100 and plan on looking forward to any further advancements
in their line.

Although their 19mbps HDV codec really work REAL well,
I wish they offered a function that would allow you to switch to a 25mbps sample rate to capture even higher quality.

It has a nice "warm" color balance. Did you do a straight white balance or preset?

Thomas Smet · March 1st, 2006, 12:35 PM

I meant in terms of 4:2:0. These shots looked more like 4:2:2 than other shots from the HD100. Maybe it came from a Cineform export which actually tries to upsample the chroma to 4:2:2. It's hard to tell on real world images but when I examine the chroma channels at 400% in Shake they look more like an interpolated 4:2:2 or analog.

Straight white balance.

Thomas, these were not converted to Cineform; although that is my plan when editing.

They are frame grabs straight off of the m2t timeline.

Steve,

Can you export an uncompressed file instead of JPG? Instead does your editor allow export of uncompressed TGA or uncompressed TIFF?

Steven Thomas · March 1st, 2006, 01:03 PM

Stephen, no problem. I just uploaded a tiff.
