4KtoScale

##Resize 4K videos in bulk, no need to buy expensive software This 4 lines script create an output folder and converts in bulk all 4K .mp4 files into it resizing them to 1920:1080.
Need other format? Substitute .mp4 with whatever you want.
Need other resize scale? Substitute scale=1920:1080 with whatever you want.
By default the audio is just copied as I noticed this reduce the load of calculation, if you don't like this eliminate -c:a copy.
