720p x264 vs 1080p x265

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?

letterboxing built into the video so DVD players show them correctly. Since that loses some pixels up front, they require using higher quality levels to prevent visual lossiness.

Letterbox and pillars baked-in actually has very little, if any, impact on filesize or quality, when encoding from the same source and settings (other than the one dimension that was trimmed)

When you go to reconvert it has noticeable impact in how you encode.

I have movies with letterboxing that’s 20% of the screen. You’re going to say losing 20% of your pixels to baked-in, forced letterboxing has no impact?
