Topic: Conversion from 4K resolution to 1080p

Please direct me to video transcoding settings, convert 4K resolution to 1080p, what code to write

Re: Conversion from 4K resolution to 1080p

option 1: via SVP's frame size controls - there's no UI button "decrease to 1080p" but you can set frc.frame.resize in 'All settings' to "-19201080". "decrease to screen" should also work if your screen resolution is 1080p.

option 2: use any of ffmpeg's scale filters in 'lavfi' field in transcoder's 'Advanced' mode - the trivial example is "scale=w=1920:h=1080"

The second option is OK



Thank you for the answer



In addition, what kind of settings can be written to increase the video sharpness of transcoding
