Do DVDs use the full 720x480/576 resolution

[DrDeceit]

Does a 16:9 aspect ratio DVD use the full 720x480/576 resolution to create the image

or does it use 720x400 and crop the letterboxes (black bars)?

[aedipuss]

16/9 dvd can be done 2 ways. either 720 with wide pixels(anamorphic) or 720 with hard coded black bars encoded to 4:3

And keep in mind that many movies are wider than 16:9 so they will have black borders even on 16:9 DVDs.

16/9 dvd can be done 2 ways. either 720 with wide pixels(anamorphic) or 720 with hard coded black bars encoded to 4:3

So you're saying 16:9 "anamorphic" uses 720x480, and the pixel aspect ratio is 1:1.18

And keep in mind that many movies are wider than 16:9 so they will have black borders even on 16:9 DVDs.

I know that darnit. lol.

I was just confused, since I'm encoding a video, the source is 1920x796 2.40:1 aspect ratio, but... 2.40 should be 1920x800
So I'm encoding a 720p version 1280x544, and if I choose the "fully expand" setting for aspect ratio, it displays 2.40:1, but if I choose 2.35:1 or 2.40:1 for aspect ratio, there's slight letterboxing

So I'm guessing Fully Expand keeps the original display aspect ratio of the source, altering the pixel aspect ratio according to the resolution set

par depends on if it's ntsc or pal. but neither is 1:1.18

A 2.35:1 video should have large letterbox bars when encoded as 16:9 DVD (720x360 in a 720x480 frame). Even larger when encoded as 4:3 DVD.

[DrDeceit]

god dammit. I KNOW THIS.

I'm not encoding to DVD, I'm encoding 720p H264

[poisondeathray]

god dammit. I KNOW THIS.

I'm not encoding to DVD, I'm encoding 720p H264

encoding to 720p from a dvd source?? why ?

Just so we're clear and on the same page, "720p" usually refers to the vertical resolution. So 16:9 AR would be 1280x720

Ok, so this is a different topic? Forget about the DVD ?

If the source is 2.4:1 and the encoded frame size is 1920x796 (that would be very atypical, it must not be an original source, or you are mistaken somewhere). It must be cropped already, or maybe the other person made a mistake, or overcropped (sometimes a blu-ray will have grungy edges, and some people overcrop their backups)

Maybe you can add what software you're referring to. What does "fully expand" refer to ? Which program ?

Just crop the borders and resize to the square pixel AR you want

Yes, different topic

1280x544 is considered "720p" in common use if the video's aspect ratio is 2.35:1 or 2.40:1
No need to encode it at 1280x720 and apply letterboxes, or pan&scan and screw up the aspect ratio, or mess around with the pixel aspect ratios

Format Factory, its more versatile than people give it credit for, you just have to know how to use it

Setting the aspect ratio preset to "Fully Expand" results in the video displaying with the source's original aspect ratio, no matter the resolution, no letterboxes

So, I could encode it with 600x600 resolution, but when it plays, its display aspect ratio will not be 1:1, it will be 2.40:1

Yes, that's the same thing cropped. If you added the borders back, it would be 1280x720. Another way of putting this: if you resized the original blu-ray (which had letterboxing), it would be 1280x720. If you want to play it on a blu-ray player, you actually need the letterbox (although some newer blu-ray players can play cropped mkv directly from usb , for example)

I have no idea what format factory does.

You just need to resize to 1280x544 if your intended target was PC playback . Many programs can do this

So all it does is set the pixel or display aspect ratio for you -- to match the source video's aspect ratio.

I'm not having any issues with my encoding, lol

It seems you're mistaking my statements for questions

[poisondeathray]

whoops I misread it sorry . What jagabo said makes sense with your observations

When I read that I thought you switched to a 1280x544 source and were still making a DVD. It's now clear what meant was you were now making a 1280x544 video.
