    Preserving the full raster of an HD clip in an SD timeline

    Hi all-

     

    I am working in an SD project (30i NTSC) and have some HD clips (1080i 59.94) that I want to incorportate into it. What I am trying to accomplish is to edit my HD clip into an SD timeline and preserve the full raster of the image so that via the resize, pip, or pan & scan tool, I can effectively "zoom in" to a specific area of the image. Any thoughts on how I may accomplish this?

    This is what I've done so far: I created a new 30i NTSC project. Under the format tab changed the project to 1080i/59.94. Captured my clips and switched the project back to 30i. Great, now I have my HD clip in my SD project. But..when I edit it into a timeline the Avid scales it to fit the program monitor and if I try to scale it up, it appears to not maintain its HD resolution. This is where I'm stuck.

     

    Thank you in advance for any input/ suggestions.

    That's a limitation of Avid's architecture. It's the same reason you have to use Moving Picture to maintain original quality on a still. You could resize and render while in 1080 mode, then switch back to SD.

    Agreed. We also do this type  of work in After Effects.

    Will the Reformat FX effectively do this?

    hmmmm, now  that  you mention it...how about Pan  and Scan?

    NEver used it that way but sounds like something that should work.

     Terence, How much better is Moving Picture than the Pan and Scan in Avid?  Jus' wunderin'.  Cheers

    Moving Picture's equivalent would be Pan and Zoom

    Pan and Scan is the reformating FX that resized your video. In the Symphony Meridien days, this was the FX you wanted in order to preserve quality. I'm not sure how the render engine of this version works. It may or may not work.

    DMcL:

    Moving Picture is better than Pan & Zoom ( a confusing choice of naming with Pan & Scan), because it has a rotate feature which Pan & Zoom does not. You can also set a default folder to look in which is handy when conforming a show that was offlined elsewhere. And, you can tell it to handle the RGB to 601 remapping of stills.

     

    Pan & Zoom however has been fixed in the later versions of Avid to not automatically load the high res still until render so you don't use up all the memory of the system. Moving Picture can't do this, probably an AVX limitation, and working with a timeline with lots of MP plugins in HD can be murder.

    That was because there was a dedicated chip on the Meridien board for this effect whose quality was far superior to the Pinnacle Video Destroyer card.

     

    Now it's all CPU render so it doesn't matter. What you want to do now is enter the console command "SetResizeType 9" to get a higher quality resize render.
