Combining 4:3 ratio with 16:9 ratio footage

...

The guide doesn't presume all widescreen footage is 2:1

It presumes that in order to make anamorphic footage have the same Pixel aspect ratio as 720x480 '4:3' footage (which presumes that 720x480 footage becomes 640x480 to make it 4:3).

The reality is actually far more complicated than that and involves cropping to 704x480 before resizing and so on... but that's a real hassle. The math in the guides works, we've discussed this at length before. 720x360 is '16:9' in the same way that 720x480 is '4:3'.

As for finding an intermediate aspect... I'm not convinced.

AD, what you say is entirely true IF you're dealing with the NTSC's stupid 0.9 pixels. However, most music video watching is done on computers, and most people's computer screens have square pixels.

Now that I have my Eva Renewal box, I'm currently experimenting with cropping everything to a 20:13 ratio; it's fantastic so far. No distortions, no changes in blackbar size, and little enough cropping to be completely unnoticeable. In fact, I'm only cutting about half as much area off the episodes as Death did (but not Rebirth, since that was all new stuff).

20:13 rules!

Monarch,

That might be so, but it seems to me that most people really don't want to learn that.

What I've seen is that most people, including myself when I started wanted to know what size to make their video. 16:9 means not a whole lot when it's 2:30 am and your avisynth files keep looking like those old kung fu theater credit sequences (all scrunched up) or all the people look like widebodies.

In addition to explaining things in a way that relative newbies can understand AD's page has those *magic* numbers that everybody wants.
LanczosResize(720,360)
Addborders(0,60,0,60)

If you post a picture using your 20:13 ratio compared to the 16:9 as described in the guides that might help, till then I'll be sticking with what works.

In the words of the great and powerful Eric cartman, "I would if I could, you son of a bitch!"

In other words, it would be most kind of you to inform me of HOW, exactly, I am to post pictures on these forums.

I can't speak for everyone else but I produce by videos for conventions.

Hence the 0.9 PAR.

Aspect ratio can always be fixed at the end for computer users and it's more than likely that if you are working online you are going to end up resizing the video to a lower resolution when you compress anyway.

That's another wierd thing - If I make two encodes of the same video, using the same codec with the exact same settings both times, but one is 320x240 and the other is 640x480, the larger one will look a lot better when both are full-screened. The hell?

No need to go all south park on me now.

You seem like a pretty smart guy so I'm pretty sure you're not talking about using the image tags or anything like that.

if you email me a couple of reasonably sized pics I'll host them untill this thread dies off.

Then the world will know the greatness of your 20:13 ratio editing.

done.

And I meant posting images directly from my hard drive to these forums... anyone can link to an image on some website somewhere.

Ah, here we go. Our first example is a scene from Episode 19 of Evangelion, cropped from 4:3 to 20:13.

Our second example is a scene from End of Evangelion, cropped from 16:9 to 20:13.

As you can see, the difference is really not that noticeable.

It'd be nice if you labled which is which, as well as using LOSSLESS PNG instead of LOSSY JPEG. But we live in the matrix so LOSSLESS PNG wouldn't make much difference now would it ?
