The output video should look very pixelated. I've already tried Lanczos and Spline (they were mentioned as 'the best ones when scaling down' in my second link) and the first thing that surprised me was nearly no encoding time difference when compared to default method but the only differences in the output file I could notice were the more smooth gradients.I am interested in scaling a video to a larger size without applying any filter or anything.

I think the most popular 'not default' filter is Lanczos. I can imagine that selecting the proper filter can be crucial when scaling the video up but what about scaling it down?

So far I've mostly used the default scale filter method to scale the x264 video resolution down, for example -vf scale=720:576 but I've noticed that some people often use -vf scale=720:576:flags=name (or -vf scale=720x576:flags=name) where name is the name of the filter.
