i have some video at 2048x1152 that i need to resize to 1920x1080. i'd like to fold the resizing into other parameters i'm feeding x264 so i can do it all at once. i thought i'd use lanczos as the method but would be happy to be corrected if that's not the best method for this. what is the cli command for this? should i use fittobox? what is the syntax to do this resize?
thanks,
BabaG

Code:
--vf resize:1920,1080,method=lanczos
- method: use resizer method ["bicubic"]
- fastbilinear, bilinear, bicubic, experimental, point,
- area, bicublin, gauss, sinc, lanczos, spline -
thanks very much, pdr. very quick response. i'll try it soon. so, for lanczos, there's just the one option? no lanczos3, lanczos4?
thanks again,

Those are the only options because the patch was "borrowed" from ffmpeg swscale
https://ffmpeg.org/ffmpeg-scaler.html
If you're wondering, "spline" is sharper than avisynth's spline16, but softer than spline36
But 2048x1152 => 1920x1080 isn't a large change, so you won't notice as much difference between them than if you were use a proportionately larger change
