is 1440x1080 (1.333) the same as 1920x1080 (1.0)
 
hi all, i just downloaded a sample .mov from a 5D which is shows in premiere as 1920x1080 (1.0 aspect ratio). I then mixed it with a sample m2t from a sony Z5 which shows as 1440x1080 (1.333 aspect) however both fit the screen and display the same size in the output window.

As both have the option of shooting 25p am I right in saying that if I had one of each cam, the footage could be cut together with no real problems... same frame rate (25p) same frame size ... sort of (1920x1080)

Is it a case that the 1920x1080 at 1.0 is better quality than the 1440x1080 at 1.333 however, as premiere interprets it as 16:9 they can both be edited together ok?

Many thanks

I've cut HDV (1440x1080 1.33 aspect ratio, when "unsqueezed" is 1920) from a Sony FX7 / V1U and 5D material (1920x1080 1.0 square pixels aspect ratio). Typically HDV is 60i, so Premiere internally handles mixed frame rates itself. But since your Sony Z5U offers 25p in HDV, you can have a common sequence in 25p. You can either create a custom sequence preset (using custom, desktop, and 1920x1080 25p), or just use a similar preset from any DSLR, HDV, AVCHD preset that is 1080@25p.

You should have no problems mixing 5D and HDV clips on the same timeline. I do it all the time. I get good results setting the sequence settings to HDV. Premiere handles the 1.0PAR footage without a hitch.

As far as quality goes, there are a lot of other factors more important than number of pixels. Matching the 2 cameras will take a little experimentation, but pixels aren't the problem.

thanks guys, its good to know others mix 5d and z5 without problems.

I am stuck as to what to do now as I want to buy a Z5 and 5D (or maybe 7D) however in those situations where I film a 2 cam shoot (I dont think I'd trust the 12 min record limit/overheating on the DSLR at a wedding) the 2nd cam will be an FX1, shooting at 50i. I know I can't really mix 50i and 25p without them looking totally different. Is this also true where movement is limited? Is there any way of making the 50i look like 25p without losing quality/it looking like the awful cineframe mode on the fx1?

Appologies if this is the wrong place to ask this question, I dont like to start too many threads in my never ending quest for knowledge!

I'm not sure I understand this problem.

When you are multi-camming with a Z5 and an FX1, why not shoot both cams in 50i (60i in NTSC land) and convert your edited ceremony to 25p later in your NLE?

(By the way, as was recently pointed out to me, the revised terminology is "25i" rather than "50i" even though the camera manuals and settings still say "50i" and "25p." Now, we are officially supposed to call it "25p" for 25 progressive frames, "50p" for 50 progressive frames, and "25i" for 25 interlaced frames with 50 "fields.")
