1440 vs. 1920 at DVinfo.net

Adam Gold · January 29th, 2009, 11:11 PM

Just upgraded to Prospect, and maybe this feature was in Aspect but I didn't notice it: I can convert from 1440 to 1920 upon capture.

So, does it make a difference? Does it matter whether I set up a 1920 project and convert all 1440 upon capture, or just do what I used to do: a 1440 project at 1.33?

Couldn't find any recommendations on the Cineform site about this.

I wouldn't bother unless you are mixing 1920x1080 and 1440x1080 footage. The 1920x1080 makes sense if you have a 1920x1080 camera, but interpolating your raw footage won't look any better than interpolating to those dimensions for your final render if you want a little extra resolution for your titles and graphics.

That's what I thought, but just wasn't sure. Appreciate the help.

So it looks like you could go either way and it won't make a huge difference, especially with HDV.

I'm still impressed with 1920 sq pix with regard to direct transcode to other formats (DVD, BR, Flash, etc.), so I bring everything into a project as 1920x1080. I can output whatever delivery format I need directly from the CF 1920 timeline with AME or Procoder and get excellent image quality.
This represents a huge simplification and time savings over my prior 1440 workflow.

Hm. Might be worth an experiment. Thanks for the input.

One difference: on my Q6600 capturing/converting HDV to CFHD in it's native 1440x1080 happens realtime. Capturing/converting/resizing takes quite a bit longer so I end up sitting drinking too much coffee at times.

And no, it wasn't a feature offered in AspectHD (as its resolution limit was 1440x1080).

Another good use to up-convert is when you want to create 720 footage with pan's and such... you bring in the 1920x1080 and you can pan,crop,crawl... then output the completed scene at 720...
