MacOS' display resolution can only be changed with the macOS settings or a third party application. You will want to change it on the host's computer directly in the Windows Display Settings. If a friend is joining, the host settings in Parsec will not take effect and they won't be able to adjust the resolution from the overlay. To add a custom resolution to the host computer, use the Windows Display Settings or the AMD/NVIDIA control panel. If your hosting computer does not support the resolution that you're requesting based on the Windows Display Settings, Parsec will switch to the closest resolution available. When you're the owner of the computer, you change the resolution from the Parsec overlay, or set the resolution the primary display will use when you join, in the Parsec host settings. Parsec does not downscale the resolution for the guest, and any settings in Parsec will only adjust the host display's actual resolution. The resolution of the stream is always the same as resolution of the host's display that is being captured. In both modes, you can check the current resolution by looking at the Parsec overlay in the guest. In the video details the bitrate must be lower than 3998 kbps, otherwise you will not decrease file size.Depending on whether the game is being hosted in the Computers tab or Arcade, the resolution is changed in different ways. You can check the bitrate of the transcoded clip using ffprobe INPUTFILENAME. Maybe you want to check the crf value with a smaller part on your video. The -crf value should be between 18 and 31. Higher values will give smaller files in lower quality. You can vary the video quality by changing the -crf parameter. Replace INPUTFILENAME with the correct filenames on your system and give an OUTPUTFILENAME with the same extension as the INPUTFILENAME. If you simply want to transcode (1080p -> 720p) you can use ffmpeg (this command line will leave your audio untouched).įfmpeg -i INPUTFILENAME -c:v libx264 -r 25 -preset slow -crf 24 -c:a copy -vf scale=1280:720 OUTPUTFILENAME All in all the filesize does not depend on the screen size, but of course you will get better picture quality with lower bitrates on a smaller picture. What you have to do is to lower the total bitrate (audio bitrate + video bitrate). Well, I have understood that you want to decrease file size.

Ffmpeg resize video to 720p
