Maintaining original source quality

Post by fnibble »

Description of problem or question:


Simple duplicate of original resolutions.

Steps to reproduce the problem (If Applicable):


Is there any method of duplicating the original resolutions in Handbrake. It seems to be set up to condense files. It would be very helpful if there were a box to tick that says "Same resolution as source". If you are a novice at this sort of thing, the various option menus are very intimidating, and modern NAS storage costs mean that stuff can be transcoded on the fly.

HandBrake version (e.g., 1.0.0):




Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):

Many of HandBrake's presets produce output that is "the same resolution" as the source. But it sounds like you want video passthrough which isn't the same thing. Video passthrough would copy the original video without first decompressing and then recompressing it. HandBrake can not do this. HandBrake is a video transcoder, so it will always re-encode the video. What you are looking for is a remuxer. ffmpeg and the various frontends available for ffmpeg can remux.

Assuming you don't pick a resolution constrained preset that is lower than your source resolution (either pick one at or above your source resolution, or one with no resolution limit), HB will not change the resolution of the video by default. There is one exception, that HB will crop off useless black bars top/bottom/left/right if it finds them, but you can disable that by setting cropping on all sides to 0 and saving that in a preset.

But if you have cheap storage and on the fly transcoding, you may not need HB at all. Just rip your disks with MakeMKV and skip the time waste of a HB encode.
