1920 x 1080 ?

[Ian Wright]

thanks for the explanation. So presumably the extra 480 pixels that the G1 outputs are created by interpolating the 1440 pixels to produce 1920. The values of every 3 horizontal physical pixels are used to create 4 virtual pixels. Is that it?

Presumably that's the same as what happens when you import your 1440 HD into a 1920 timeline, the interpolation being done in the pc/mac.

Thanks

Not exactly. My understanding, and I might not have this exactly correct, is that the A1 and G1 actually produces 1920x1080 signal using a pixel shifting method. The actual pixel count on the 3 sensors isn't as important since they are analog and when converted to digital, it works out to 1920x1080. The signal is then either compressed and resized to 1440x1080 for recording to tape, output through firewire or component, or it remains untouched for output through the SDI connector on the G1.

However, I think you're on the right track with what happens on the timeline.

The Cinemascope aspect ratio which is 2.35:1 is used in some of the films you would see in the theaters. I just happen to like that look. In the A1, you can set up guides to help you frame for that aspect ratio.

Oooh, very cool! I will look into Cinemascope. Sounds like a great format. :)

Thanks a billion Marcel!!!!

Cheers,

Again, I've only done this in SpeedEdit and it works very well. Your results may vary with other NLEs. Give it a try and see what happens.

I have done (kinda) similar things with After Effects... But this was for a web banner:

Create 800px X 250px (or whatever dimension) square pixel project, and drop-in my 1440x1080i footage... after de-interlacing, it worked pretty well.

I am excited to give your technique a go in FCStudio. :)

Cool. Let us know how it works out!

For sure! I will give it a go on Friday.

Thanks again Marcel!!!! You rock! :)
