I have a video in 4k that i would like to downscale to 1080p. What i want to do is having the video with the same quality and carachteristics as the original but at 1080p.

I have tried the following:

1.- changing the output resolution to 1080p. 2.- stablished the "Percentage scale for render resolution" to 100%. 3.- Output: FFmepg 4.- Encoding: - output quality: Losless

the problem is that I ended up with a file with a size of 8 GB when the original video file 2GB.

Any help, please?

  • Which quality is it you are talking about? The quality I am thinking of cannot be preserved when changing from 4k to 1080. – Yunnosch Jun 17 at 21:29
  • I guess your input video isn't encoded as lossless, otherwise it would be much bigger as well, it must already be encoded with compression. Try using a compression if you wnt a smaller file. – Leander Jun 17 at 21:33

You have to use a compression like H264. Your 4k Video has also a compression on it and that the reason why it is smaller than your 1080 video.
