    Improving Resolution when working with SD footage

    I have a project using all old DVCAM clips, which I need to deliver as an upload for for the web.  I did not digitize these clips myself--they were already given to me as a standard def Avid project on a hard drive.   I found that changing the project resolution to HD (1920x1080 30p) before cutting the project, and then exporting a QT ref and using Squeeze to resize back to 640x480 when I create the Mp4 upload file results in a better image than cutting and exporting as an SD project.  I have no idea why this is, but the improved quality difference is noticable.

    Re: Improving Resolution when working with SD footage

    I've only ever found Avid up and down scaler to be useful for offline work. It's fast but not very "clever" better results, as you've discovered, are obtained with external scaling tools.

    If you have BCC, that has an effect that is called UpRez. This allows for higher quality upscaling, with various algorithms.

    You would then need to export your SD footage from the SD project (as SD, Same As Source, 709 levels), then import the result back into your HD project with the option "Do Not Resize Smaller Images" selected. This will give you an SD picture inside an HD canvas, with black around it. Apply BCC UpRez, choose 'SD D1' as the source aspect ratio and 'HD 1920x1080 square pixels' as the destination. Then tweak the settings at will, most of all the Quality options.
