Before outputting the video, I wonder how to set the codec quality, GOP, and B frame in the advanced settings to output the video with the best quality. Also, please tell me the same settings should be set for video output at 1440 resolution.
Turn off Export > Use hardware encoder and choose Export > Presets > lossless > H.264. It does not matter what the resolution is. But it will be slower than hardware encoder, use a lot of power, and make a large file, which some people do not think is “best.”
Thank you so much for your kind reply. I can edit good videos with Shotcut.
