480x30 bigger than 1080x30 at same screen height?!

Post by davebit »

I'm ripping a music video from a DVD (which is 480p), and Handbrake's default selection is 1080x30, so I figured I'd rip it at that then rip it at 480x30 and compare the image quality and size etc.

While both look fine, the 480 video is larger in MB and has a higher datarate while the 1080 version says it has the same resolution (720x480)!

What is going on?! I'm afraid my 1080 version won't play on older devices.

HandBrake’s presets are “up to” whatever resolution. Both files are 480p, as HandBrake will not upscale the resolution. What you’re seeing is a difference in the quality setting for each preset.

@BradleyS: If the difference is quality, why is 480 more file size data than 1080?

@mduell: This is a support request? Why do you need an activity log for two files encoded at 480 and 1080? I'm having a hard time believing you're either not able to explain what I've already shown you without an activity log or trying it yourself. Does this happen to you or have you not tried encoding the same source video with these two different bitrates (Fast 480p30 and Fast 1080p30) and compared the file size...

You ask why the difference, but do not supply the information that tells us what you did differently.

Given the information you supplied so far, the answer is, "You used different settings".

If you want to know WHICH settings had the most effect, show us what settings you used, and how handbrake applied them to your source. That information is found in ..... the activity logs.

Because users are bad at describing what they did, what they did it with, and what they did it to. The log is a convenient way to accurately answer a lot of questions.
