    I need to find out which one of the above screen types a certain video is.

    The info tab does not have that information.

    No, but it has the resolution.

    Divide them, compare to 16/9 and 4/3.

    By inspection of said video.

    4:3 is very 'square'. 16:9 is quite wide in comparison. You understand how the ratios work right?

    Select the file and click on get info. It will tell you the dimensions.

    Depends on format, but aspect ratio will tell you.
    For example, in DV, 0.9 is 4:3 standard, 1.2 is widescreen 16:9.

    You can't always tell without playing the video and looking at the output.

    You could consider the ratio as someone said, but then you could also have non-square pixels.

    What software are you using ? Final Cut (Studio or Express) ? iMovie ?

    Like they said, it will be pretty obvious when you play the file. If it's a rectangle, it's 16:9 if it's almost a square, it's 4:3.

    Hi Newmacuser23,

    This may be relevant or not:

    When I worked in broadcast, occasionally we'd get a file which appeared to be what it wasn't ... ie. 4x3 masquerading as 16x9 or vice versa.

    Try playing the video and looking for something circular in it - like a wheel etc.- and looking to see if it appears stretched vertically (16x9 playing as 4x3), stretched horizontally (4x3 playing as 16x9), or just right.

    Alternatively, people are often a good measure - look to see if they appear elongated or excessively fat ... (Though sometimes it can be difficult to tell!)

    Hope this helps,

    Cheers.
