Zoom in x200
Left: 720p x264 --> 0.25 GB
Right: 1080p x265 --> 1.11 GB
I tested watching both on my phone:
- Without zoom, I didn’t notice much difference in visuals.
- The audio is stronger at the same level on the x265 version.
- I need +15 volume level (Android) to make the x264 sound equal.
What do you think, guys? Is it worth 4 times the file size?
It’s not just about codec and resolution, either. Every algorithm has a bunch of parameters that you can adjust, so you could get a 4k60hz video with a reasonable file size and still have it look like crap. And that’s not even mentioning the audio quality.
