I have two videos: first one has 50% higher bit rate, second one has 20% higher resolution and slightly higher FPS. Which one will look better? I use a 1080p 72 inch 60 Hz screen at 10 feet distance.

Could you give files (or png screenshots) to comparing? I think that file with higher bitrate and higher resolution should look better, with other conditions being equal.

1056*594 = 627 264 pixels. 1280*720 = 921 600 pixels (47% more pixels relative to 1056x594 resolution) 921 600 / 627 264 = 1.469 * 100% = 147% relative to 1056x594 resolution.

2966 kbps for 1056x594 - 43% more bitrate for this video, relative to 1280x720 2073 kbps for 1280x720 2966 / 2073 = 1.43 * 100% = 143% relative to bitrate of 1280x720 video.

What do you think? I think that with these settings both videos should be approx equals. Maybe the subjectivity of the perception of the human view will make its adjustments in this comparing.

  • The files are too large to send them Apr 14, 2020 at 4:37
  • You can upload png screenshots to comparsion image hosting or to cloud drive and attach link to the next comment. Apr 14, 2020 at 22:29
  • It is supposed to be the same frame from the 2 videos, right? There is no point comparing different frames? How I am to find exactly the same frame in two videos? Apr 16, 2020 at 7:24
  • You can find the same frame in any video editing software. Or with ffmpeg, as example: stackoverflow.com/questions/27568254/… Apr 17, 2020 at 16:24
