1920x1080 dropping to 1804x1080

[skipfire]

I've searched and haven't found this in the forums, and if I'm not understanding something that is basic it is possible I am just being an idiot. I have tried uninstalling and reinstalling, multiple discs, and multiple computers.

Anamorphic is NONE, Modulus is 2, Keep aspect ratio checked

Handbrake says the source is at 1920x1080 with an Aspect ratio of 1.78 and PAR 1/1, though I had never noticed the PAR before the new 0.10.0 release. With some discs I see handbrake change the 1920 width to 1804 but leaves the 1080 height which results in a different aspect ratio. If I try to manually change the height it will not let me go above 1804 unless I uncheck the aspect ratio box.

I'm guessing I just don't understand something, but if someone could explain what I am not understanding or tell me what I am doing wrong I would appreciate it.

I just had another one that was also 1920x1080 Aspect 1.78 PAR 1/1 want to go to 1920x1040 which again doesn't match the aspect ratio listed. I just looked at the box and it says it is 1.85 which does match 1920x1040, so maybe the aspect shown by HB is off?

We have no idea what your source and settings look like without the log.

I was asking just for some education on how the numbers worked so I didn't think specifics would even be relevant. After more playing with various videos I think there might be a bug that is preventing the real aspect ratio from showing in the HB GUI as the only ratio I see is 1.78 even when the numbers picked for width and height match the box and are different than 1.78.

As for the 1804 I am guessing that there is something built in that will max the height to 1080, so it then scales down the width to hit the ratio of 1.66.

handbrake's cropping is doing it's job...

Surprise surprise, the logs tell all!

Code: Select all

[11:32:34] scan: 10 previews, 1920x1080, 23.976 fps, autocrop = 0/0/58/58, aspect 16:9, PAR 1:1

[11:59:39]      + Crop and Scale (1804:1080:0:0:58:58)
[11:59:39]        + source: 1920 * 1080, crop (0/0/58/58): 1804 * 1080, scale: 1804 * 1080

Autocrop found black bars for 58 pixels on the right and left sides, so it cropped them off leaving you with a 1804x1080 picture. There's no reason to stretch or distort it back to 1920 wide.

The original resolution and aspect of the disc is 1920x1080 16:9. It has black boarders at the left and right of the frame that are 58 pixels wide each. After removing these black boarders, the resolution HandBrake encoded is 1804x1080 (1920 - 58 - 58). The new aspect after removing the black borders is about 5:3.

5:3 seems like a non-standard aspect. So I'm not entirely sure that autocrop has done the right thing in this case. Sometimes a video that is exceptionally dark for a large portion of the content can trip up HandBrake's black border detection. So you should check the output to see if it looks like it cropped away valid content.

Another possibility is that the video is really 4:3 and HandBrake didn't detect all of the black border and left a small amount of black around the frame.

You could always uncheck 'auto-cropping', run HB and see what you get.

This is actually something I was searching for as well, maybe something to add to an FAQ - in the previous version of Handbrake for Windows, you set the width (e.g., 720) and even with autocropping going, the resulting video would be 720 wide. As in, it'd crop, then scale it back up to the desired width. With 0.10.0.6534, it doesn't scale it back up, leaving folks like me confused and wondering if something is wrong. Turns out the previous behavior was probably wrong and this is actually how it's supposed to work. (Right?)

@tiliig correct. There is no benefit to scaling it back up. You can't make resolution out of nothing.

5:3 seems like a non-standard aspect.

I just searched it, and the original theatrical aspect for Dr. No is 1.66 (5:3). So assuming it came from a BluRay, it should stay at 1800x1080.
Just curious as to why you're encoding a movie from an mp4, rather than your original BD rip?

1.66:1 (5:3, 15:9): 35 mm Originally a flat ratio invented by Paramount Pictures, now a standard among several European countries; native Super 16 mm frame ratio. Sometimes this ratio is rounded up to 1.67:1. From the late 1980s to the early 2000s, Walt Disney Feature Animation's CAPS program animated their features in the 1.66:1 ratio (a compromise between the 1.85:1 theatrical ratio and the 1.33:1 ratio used for home video), this format is also used on the Nintendo 3DS's top screen as well.

Yes, the old behavior was a bug.
