Change to 1:1

[jriker]

I have a video that handbrake shows as:

Source: 1280 x 536, PAR 67/68

Setting anamorphic to None it shows:

Storage: 1262 x 536, Display 1262 x 536

If I'm converting this video with AVISynth and doing some other stuff in VDub with it at the same time, what should I resize this video to in order to be 1:1. Video will be a hard drive file played to my plasma tv. I've done this a lot before with HD digital content but not with a size measure like this file.

Thanks.

If you're using avisynth, you don't need to do anything else because it assumes "square pixels" by default

[jriker]

Thanks. Kind of knew that but didn't think it was necessarily doing it right. Thought that AVISynth thought all files were 1:1, not that it set it properly. AVISynth script opening in VDub is coming up as 1280 x 536. Should I assume that's the correct 1:1 even though the file is supposedly 1280 x 536 at 2.35:1 display aspect and 0.985 pixel aspect?

Should I assume that's the correct 1:1...

Yes.

...even though the file is supposedly 1280 x 536 at 2.35:1 display aspect and 0.985 pixel aspect?

In this case that's a bunch of confusing mumbo-jumbo.

1280/536=2.39:1 (Probably the most common aspect ratio these days)
2.39x.985=2.35

[poisondeathray]

If you want to reproduce it like the source (which might be incorrect), you still don't do anything different in avisynth . You would encode with --sar 67:68

Or leave it 1:1 square pixel, which would give 2.39:1 as manono explained

[Keyser]

Width / Height » DAR / SAR ==> DAR = (Width * SAR) / Height

In your case: DAR = (1280 * 67/68) / 536 = 2.35 ; which you already know from MediaInfo output.

So with a SAR of 1:1 we have: Height = (Width * SAR) / DAR = (1280 * 1/1) / 2.35 » 544

You should resize to 1280x544. I think it is a better choice than 1262x536 which, by the way, to be exact should be 1260*536. 1260 is a more exact number (536 * 2.35 = 1259.6) and it's mod 4 while 1262 is mod 2.

[manono]

You should resize to 1280x544.

I disagree. Why take a 1:1 1920x1080 Blu-Ray, crop the black bars and resize to 1280x536 (still 1:1) for internet distribution, and then add a PAR to have it play at the wrong aspect ratio? 2.35:1 isn't even used these days (assuming it's a relatively recent movie). If a PAR was added it's only because it was done by an incompetent encoder that didn't understand what he read or was told. The same principle applies if it was a 1080i or 720p capture from television.

2.39:1 (~12:5): 35 mm anamorphic from 1970 onwards. Aspect ratio of current anamorphic (wide-screen) theatrical viewings. Often commercially branded as Panavision format or 'Scope. Specified as 2.40:1 for Blu-ray Disc film releases (1920×800 resolution).

If the PAR is wrong and the true DAR is 2.39, I totally agree with you!
