Probably User Error but can't seem to fix it

Hi, I noticed today, when working on a project that VMS is reporting my video as interlaced.

Video: 1920x1080, 29.970 fps interlaced.

I use Match Media Settings when starting a new project. Started a test project to see and it does the same.

I am shooting on a Canon HF20 at 1920X1080 30P

So, first question, is this something I need to worry about ? Will it affect the outcome of the rendered movie ? The end result is slated for BD.

Do I need to manually override the settings by editing the clips settings ?

I verified this by shooting a quick test clip. Still shows it as interlaced.

Thanks

"The 24p and 30p modes are identical to what you'd find on the Canon HF11 or HF S100 (really any HD camcorder from Canon). The two modes are not natively progressive, which means they are actually recorded as 60i streams, with Canon implementing a pulldown system to give the footage the look of 24p and 30p footage."

Canon's camcorders shoot in PF30, not in 30p. PF30 means "30 progressive frames in a 60i wrap", not "30 progressive frames". You can deinterlace these files by manually telling Vegas that these frames are progressive, and using "none" for deinterlacing method in the project properties dialog. This is to be done if you want to export progressively, e.g. for Youtube or PC viewing.

However, the Blu-Ray standard does not support 30p (the now defunct HD-DVD did though). So for Blu-Ray is best to shoot in 60i, not in PF30. For the already shot footage in PF30, simply treat it as 60i in the project properties (upper field first, none for deinterlacing).

Just downloaded and installed mediainfo. This is odd, it too is reporting 29.97 interlaced.

Double checking my settings again, then going to try shooting another clip and validate that.

Hi Eugenia.

My mistake, I had interpreted 30PF as being 30P.

So what you are saying is it is better to shoot in 60i all the time.

Yes. For Blu-Ray, that's your best choice.

Thanks, as I suspected, user error :-)
