Project Properties 23.976 IVTC film

I am using a Panasonic GH2 set to 24p Cinema 1080 progressive mode. Am I right to set the project properties in vegas to 23.976 IVTC film and field order to None (progressive scan) to properly deal with the video clips? If I used an interlaced setting and 25fps PAL instead - what differences would I see.
Thanks

If you set it to PAL you will get ghosting, unless you also disable resampling. Just edit/export at 24p.

Thanks for reply. When you edit at 24, does that mean the 23.976 option or can you custom set it to 24 exactly?

It depends on the source footage. If the source footage from the camera is 23.976, then that's what you should use in both the project properties and the exporting dialog. Even getting the project properties setup by 0.01 frame of difference over the original footage, on Vegas it creates ugly ghosting (it's one of the bad usability points of Vegas actually, resample should have been disabled by default).

The output from the camera is 24 Mbps - so that means there is a difference doesn't it? The choice of frame rates does not include 24 - only 29.970 ntsc, 25 pal and 23.976 ivtc film. How do I set the properties to 24?

Well, are you absolutely certain the camera is shooting exactly 24fps and not 23.976?

You can set the project properties to any frame rate you want. Click on the value and type in your desired number.

Yes well I think you are right to ask because the clip properties show 23.976. Thanks for replying - I can also see that I can change the frame rate number as you say.
Onwards and upwards!
Thanks

A lot of times 29.97 is lazily called 30, and 23.976 called 24. It's not such a huge issue for 29.97 because 30fps is a very rare format so it's not often confusing the issue. However, both 23.976 and 24 are very common so it's important to be accurate.
