TEST – Compare EX1 to HVR-Z7 regarding Long Gop

[Ron Shook]

Eli,

[Eli Hollander] “Here is a link to uncompressed motion test:”

Thanks so much for tryin’, but now I get the same white screen as Mick and I do with Richard’s stuff with QT telling me I have to download something but not telling me what. I am developing an intense hatred for QT. Windows would at least tell me the component that I need in most cases.

Simple I’m afraid – doesn’t matter what the menu setting is or what the factory default is, without that shutter switch on you didn’t have 1/50th in at all – as was suspected.

Glad your rental house could give you that information so we could sort this one out!

Hi Eli

I just saw your grass. I think we found the problem. It must be the shutter. The motion blurr on these shots looks fine. Even though the pan is way too fast. I wish you had done a nice and slow pan to be absolutely sure. But still. In single frames I can see that there is no compression kicking in.
It just looks like motion blur. But is this Interlaced footage??

My guess is now that the shutter has to be manually set to 1/50 or 1/48 when in 25p mode and that the standard setting is 1/25. But I would love for someone who owns the camera to confirm this.

I am not convinced quite yet. Usually, on many cameras when the shutter switch is off the standard menu setting is still 1/50. Can you confirm that the in the menu it says 1/25 in 25p mode? In interlaced mode the standard is 1/100. So why would it be 1/25 in 25p and not 1/50??

Sorry Richard it is correct, you have to switch in 1/50th it doesn’t happen automatically, just like every other Professional HD camera.

I will do some more tests tomorrow to be absolutely sure. But if this is true than I will rest my case and thank you all for helping me solve this issue.
In the end it might buy this camera instead of the Z7 next week. The sharpness, latitude and slowmo option is really amazing.

Thanks again
Richard

If you shoot at 30p the shutter will be 1/30th and at 25p it will be 1/25th while at 60i it will be 1/60th and at 50i it will be 1/50th.

This is normal on most video cameras.

Unless you manually set the shutter to something else.

[Chris Babbitt]

So, is this what it’s supposed to be set at, or should it be 60 fps for shooting in 30p?

[Chris Babbitt] “So, is this what it’s supposed to be set at, or should it be 60 fps for shooting in 30p?”

The minimum setting for shooting 30p or 60i is 1/60th of a second. Shooting 25p or 50i should have a minimum shutter speed of 1/50th of a sec.

So, if I’m shooting at 30p with the shutter speed turned off, the camera sets the shutter speed to 1/30, but it should be 1/60. Is this bad? Also, does this mean that if I change it to 1/60, will I require twice as much light? As you can tell, I really don’t have a grasp on this issue.
