For example, to use bilinear instead of the default bicubic scaling: ffmpeg -i test.tif -vf scale504:376 -swsflags bilinear out. Most of the time they get blurry when trying to see them bigger. You can specify which algorithm is used for resizing with the -swsflags option. Working with tiny images works quite well, but looking at them i had similar problems. I tried all the swscale settings in VLC player, did some web searches but everything i find is about upscaling DVDs to 4k But I haven’t found a way to look at that lowres video upscaled in a hard/pixelate way. Right now I’m working on a video for a led screen with 64px height and it seems my “normal” programs are not made for that - it’s more complicated than i hoped…įor video editing im using Davinci Resolve, there I can’t work in such a small resoution, luckily i can export it though.
