David The spot looks good. I'm curious as why you chose to use the ef adapter as opposed to the stocks lenses with the black background. (is it only a black background for the 30 second spot?) How was the cutting between two cameras on one subject?

Spot looks good but I am curious about the EF adapter and lenses also. With a black background in these clips you can't tell if the DOF is shallow or not. Can you shed some light on this also? In addition....how far back did you have to stand to get these angles? with the 7X magnification of the add on EF lenses I'd think you'd have to get back pretty far to get these angles.

Thanks.

I choose to use the EF to XL adapter because the EF lenses give a softer bloom to highlights. The EF lenses also take off the steely quality of video when it comes to skin. The 30 sec spot was used for web only while the 4 minute final video was projected 50' diagonal. Filtration was not an option with the concern of mudding the final projected image. The EF lenses gave me just the right amount of diffusion without losing quality.

The cameras were set back 12 feet.

Since genlock was not available with the XL H1 in HDV mode, the script supervisor took timecode off both cameras and logged the drift. In post the editor took the log sheet and adjusted 13 frame here or there and matched eye blinks to sync both cameras

Watched it and it looked good. It is hard to see in a smallish web video but I can't really tell how much better the diffusion is with the EF lenses vs. the stock lens, but I would guess you wouldn't go through all the effort if it wasn't there. I'm sure it is more obvious at full screen or projected than on the web.

Nice job.

On a few shots (not to be nitpicky) it seemd almost as though the camera were moving or floating ever so slightly, kinda OIS style, yet I know it was on a tripod with non OIS lenses. It was just in 1-2 shots and I am guessing the talent moved a little while talking and created this "optical illusion" in my brain. Did you notice this or am I just seeing things?

What you are seeing is HDV.

I don't understand your response. What does it being HDV material have to do with OIS? I shoot with an XLh1 in HDV all the time and only ever notice this "look" when I am shooting handheld with OIS on. The OIS kind of floats to compensate for my inability to stay perfectly still. It looks better than shaky footage but does have floaty feel. That is what I thought I saw in your clips....at least a little. Was just asking if you noticed it too or I'm just crazy.

Thanks.

I think what David is implying is that this phenomenon is caused by Long GOP compression. However, this is usually only evident in digital broadcasting where the compression is very high and motion artifacts like "floating" become evident.

HDV camera origination usually never produces this problem. At least not the current crop of HDV cameras. And I will say that I have NEVER seen this issue with any of the projects I've shot with the H1.
