I'm encoding 640x480 video to 1280x720 and want to know which upsizing filter to use - linear, cubic, spline etc. I want clarity and accurate color.
Thank you.

Edmantay did some research about that.
I think for upsizing the Mitchell filter is the best.
Quote from his topic:
1) For upsizing, Mitchell is probably about the best filter you can use. It minimizes ringing, blocking, aliasing, moiré, and manages blurring well. Although Lanczos is precise/detailed, when upsizing, it exhibits some of the worst ringing effects. Mitchell also excels for cartoon-type images. For downsizing, Mitchell has problems with moiré and blur.
I use mitchell for upscaling 1080i to 1080p with great results.
