Sort of like the investment firm I always wanted to form:

[Bob Jackson] “I expect that one aspect of reducing the shutter angle decreases the light, similar to stopping down the lens, but with additional effect of sharpening the shot.”
Exactly. The same rules apply between video cameras and still cameras. It’s just that with video you’re shooting 30 pictures a second. I recently shot a car show outside in sunny weather. My settings were HQ 1080p 30 1/60th shutter. I wish it was up on my web site for you to have a peak. I shot completely handheld over the course of 2 hours or so and was quite happy with the result. But what one is shooting definitely determines the shooting mode.

[Bob Jackson] “Should i use a smaller shutter angle too?”
You can stick with the default shutter angle, which is think is 180 degrees. Minimum shutter speed for smooth slow panning is 1/60th per second for 60i and 30p. For freezing faster action you can increase the shutter speed up to a point, then you start seeing a stroby effect referred to as the “Private Ryan” look. Higher shutter speeds also affect the amount of light hitting the sensors, just like any other DV camera.

Hi Bob,
Welcome to Creative COW. It’s been suggested that 1080i 60 and 720p 60 both have the same temporal resolution so either one of those should work provided you use your shutter speed accordingly. 720p 60 would be better if you want to export a still image, as there won’t be any interlacing artifacts, or “combing” in the still. It really boils down to the kind of look you want. You could conceivably use 1080p 30 and as long as you pan with the race car it will remain in focus and the background will have lots of motion blur.
In order to see what look you’re after you need to get you and your camera to the edge of a busy street and do some tests. For what it’s worth, Sony put several EX1 cameras in some aerobatic planes and they chose 720p 60 mode. The results were quite nice.

[Roelf-Jan Wentholt] “When focussing on ‘eternity’ (how do you call this in english?)”
It’s officially called “infinity” in English. But I think I like “eternity” better, now that I’ve heard it.

Hi Daniel,
I’ve been waiting for others to have a look at your yellow Mustang clip and offer an opinion but no one else has stepped up yet. Personally I can’t see a whole lot wrong with the clip other than the camera shake. Unless I’m really missing something. Could it be something as simple as shutter speed? Were all 4 cameras set to the same shutter? Minimum shutter should be 1/48th for 24p and 1/60th for 30p and 60i. Unless I’m missing something…..
I’ve done 180 degree pans in about 2 seconds with my EX shooting in HQ 1080p 30 @ 1/60th and have found the results acceptable, even handheld. I can point you to the sample if you want.
I’m not being very much help, am I?

Daniel,
Have a look at the .mov file at the link below. You have to have the EX codec on your computer in order to view the video clip. If what you observed from your shoot is similar then there’s a problem with the EX cameras you rented and is not the norm. They might be early versions of the EX1 and some of those suffered from a failure of the optical image stabilization systems. My first EX had this problem once but it wasn’t anything like the sample from the provided link below. I can assure you that healthy EX1 cameras do not have the problem you’ve described. I shoot overcranked footage all the time and have never seen this issue on my present EX. Here’s the link:

I had a look at your frame grabs and the tape transport mechanism of your XL1 needs to be cleaned and serviced by an authorized Canon repair facility. Whoever did your recent service didn’t do a very good job. Last year I took a Sony camera in to a repair place to get the heads cleaned and it came back in worse shape (recording-wise) than when I gave it to them. Then I took it in to Sony Repair and all was well.
People who work in these cameras have to know what they’re doing.

Your problem with picture noise is because you set the picture gain dial to “A” which is automatic. Keep the gain at zero and dial it up when you see fit and don’t leave it up to the camera to decide.

You need Final Cut Pro v.6.0.2 to make it all work. The XDCAM EX codecs that allow you to see the picture reside with FCP 6 and not the Sony Transfer app.
