processing while opening a video file

Post by elke222 »

Description of problem or question:
Hi, I'm newbie here and have a general question to handle HB in the correct way.

I deal often with older mpeg2 video files, which were encoded or recorded with wrong aspect ratio or which were false 4:3 burned on a DVD.
So there often appear black bars all around the video, and the upper and lower bars belong to the coded picture, the right and left not.
So I see (on my 16:9 screen) a smaller picture in a whole, but with the correct target aspect ration of 16:9.
But I also have other video files, that don't play correct in vlc. When starting vlc with opening a video file, I want to play it with the correct aspect ratio and best fit on the screen, and not always to handle with aspect ratio and cropping parameters (which is in most cases functioning).

Does HB try to match the "best" settings while opening / scanning a video file?
I see that some values in screen dimension tab alter (for example 'scaled dimension'), when opening several video files (which are different) one after another. But not all values alter. So for me it's not clear which values are altered and which not (and why).
Does affect a former choosen preset the scan behavior?
Often the values match my wanted output, but not always.

Steps to reproduce the problem (If Applicable):

HandBrake version (e.g., 1.0.0):
1.5.1

Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):
Win10-Pro; 64bit, newest updates.
