Video format Q
on May 13, 2015 at 7:09:26 pm

Probably a simple one ... but realised I don't know the answer.

Sony Move Studio 12

If I click on one of my video clips in the Project Media window ... at the bottom of the window it gives the file data .. For example:

Video: 1920x1080x12, 59.940 fps etc.

Now I know what 1920 x 1080 is, and I know what fps is ... but what does the '12' stand for ?

[Rick Hughes] ".. but what does the '12' stand for ?"
It's the number of bits per pixel at an 8 bit color depth. In your case 12 bits per pixel (8 bit YUV with 4:2:0 chroma subsampling, a.k.a. YV12). YUV 4:4:4 would be 24bit, 4:2:2 is 16bit, and 4:2:0 is 12bit per pixel.

Is this normally 'set' by the recording device (i.e camera) and not something I could/should set somewhere in Vegas.

For example my camera I can set video frame size and framerate but see no setting for bit depth?

I leave this set at 1920 x 1080, 60 fps

Just happened to notice the '12'

That's correct. Vegas Pro is just showing you the details of the video that you already shot. All internal processing in Vegas Pro is 4:4:4.
