Multi-anime [Aspect ratio help]

[Ryukz82]

Ok im making my first multi-anime amv project and I already got te dvd sources I want and the song mow the problem is that I got 2 different type of sources or better saying 3 I think xD

aspect ratio sources:
1. 640:360
2. 4:3 AR(640:480)
3. 16:9 AR(848:480)

So im dealing with 4:3 and 16:9 AR footages and I just dont know what aspect ratio my amv with this footages should be or how do I combine this together without loosing quality.

Note: Maybe thisn question has been before but I just ant find the topic.

Put your sources through VirtualDub via avisynth. And the plugin you are asking for is Lanczos4Resize(w,h), though you need to download amvapp if you haven't already downloaded it yet, which contain the essential kit. Heres a guide to do with Aspect Ratio. And heres also a guide about Visual Quality which might help you.

I know how to resize them through vdubmod I just dont know the aspect ratio of the 2 different sources together I dont know if I should make my 4:3 sources 16:9 source or my 4:3 to 16:9
see what I mean?

I'd stick with 640x480 and pan/scan on the widescreen ones... but thats just me >.>
unless you like widescreen better then I'd do a smaller ratio and crop off the fullscreen's top and bottom..

really it just depends on what you like.

I see thanks

When mixing aspect ratios, I'd go with whichever is going to take up most of the screen time - if most of the footage is coming from the 16:9 source, then crop the 4:3 stuff to match. If most of it's going to be from the 4:3 footage, then crop the 16:9 footage to match. If they're going to be about the same in usage, then you'll just have to decide which one you think will work better.

I generally try to avoid mixing 4:3 with Letterboxed 16:9, as it tends to be a little jarring. If you can transition them well, then it can work though (I did something similar to that on one of my videos, where the letterboxing grows into and then off of the screen at the start/end of the widescreen segment).

Kevin Caldwell's "Engel" is another good example: all of the letterboxed footage is in the instrumental bridge, so the video only switches aspect ratios twice.

You might want to go with 704x400 (it's widescreen, not 100% 16:9 but it's the closest to it that is mod16). Your 640x360 footage wouldn't be upscaled much, and neither the 640x480 (which would obviously be cropped to 640x360 first and then resized). As about the 848x480 footage, you wouldn't downscale it as much as if you were working with 640x360 directly. Working at 640x480 would imply the 640x360 to be letterboxed or upscaled more than it would be if you worked with 704x400, that's why I'm suggesting it.

Oh geez, I just noticed the 640x360 bit now. Well in that case, since SOMEthing is going to have to be resized vertically and since nobody else has said it yet:

I can't stress enough how important it is in a situation like this to IVTC OR DEINTERLACE BEFORE UPSCALING/DOWNSCALING. That is all.
