Display Aspect Ratio rounding issue ? #171

Open Sami32 opened 7 years ago

Sami32 commented 7 years ago

I could have misunderstood that:

Height                                   : 480
Height                                   : 480 pixels
Sampled_Width                            : 720
Sampled_Height                           : 480
Pixel aspect ratio                       : 0.877
Display aspect ratio                     : 1.316
Display aspect ratio                     : 4:3
Original display aspect ratio            : 1.315
Original display aspect ratio            : 4:3

As for me 4/3 is not equal to 1.316, it seem that the PAR is used in the "raw" calculation field, but that doesn't really make sens to me: PAR = DAR / SAR. To me its look like the PAR and the DAR are incorrect.

UMS Bug Out of Sync_TX3G_subtitle.mp4.txt

Hum, first I see an ugly rounding issue (1.316 vs 1.315), I need to fix that. "4/3" is a "category" of display, not the precise thing. So e.g. all between 1.3 and 1.4 is considered in the 4/3 category (vs 16:9 for example). "4/3" is not the reference (it is taken from the raw value). with CLI, add " --Language=raw" for seeing the additional "/String" string in the field name.

720/480*0.877=1.316, so it looks fine.

Remind that aspect ratio is source of big issues (e.g. NTSC says that Pixel Aspect Ratio is 10/11, for 4:3 screen you need a width of 704, not 720, and a lot of people use 720x480 with a DAR of 4:3 exactly so not NTSC but they think it is NTSC).

Note: I don't have files with a PAR of 0.877, curious of having one for seeing how PAR is stored in it.

I saw that weird think without been sure that it was an issue, so i've now modified the title's issue. Thanks for the explanation.

Actually i checked it because we use much more for anamorphic videos, mainly used in Mangas or cartoons. I admit that after having read your comment, i get confuse: (as its seem to me that it'll be a NTSC with a PAR of 10:11) capture_07102017_185212 capture_07102017_184631

Hehe... i did anticipate it :wink: , and added the sample in an edit, but only few seconds later the first post, so i guess that it didn't get displayed in your Email notification.
