Source: mpg file
Desired outcome: VirtualDubMod displaying my mpg properly so that I can clip .avi files from it
Problem: VirtualDubMod is reading the file as 720X480 but it looks squished vertically (see below--yes, JPad should be EVEN WIDER than he is)
I tried to open it in DGIndex and got the same squish.
I would love an avisynth scripting fix or (even better) a plug-in that works

<--He should be EVEN WIDER

Any thoughts much appreciated.

I've recently started editing my vids in Sony Vegas, and I'm really enjoying the new effects and options. However, I'm having a lot of problems with the aspect ratio. What I want to do is have the vid fill out the entire YouTube screen (like so) but it never comes out that way- setting the aspect ratio to PAL widescreen gives me this, and NTCS widescreen looks like this. I know these clips are capable of filling out the screen- when I use Movie Maker, they turn out fine. I also make sure to set the Pan/Crop to 16:9, but it doesn't help. Does anyone know how to set it right?

I've been fiddling with aspect ration and frame size all evening, and I'm starting to get burned out. One question before I call it quits for the evening: does the newest version of VLC media player make anyone else's videos look funny while they play fine within other players? And by look funny, I mean stretched slightly and more pixelated. I'm a new convert of Sony Vegas, and while my older videos play fine in VLC, anything I make in Vegas... does not.

I posted this to Foolish Passion, but I figured I'd try my luck here.

First off, I am working with Adobe Premiere CS4. I don't know the ins-and-outs of the program like I should, as I just upgraded to it from 6.0 (I know!).

If any of you work in the Buffy/Angel fandoms, you likely have run into this problem: Aspect ratio. Buffy itself is in the standard Full Screen format, with the exception of one episode (Once More With Feeling) that is widescreen. Annoying. Angel is in the widescreen format. Hence, when clipping from either Angel, or OMWF, you have issues of the 'suddenly, there was widescreen' variety. In the past, I have ignored it, cause hey, I was a total newbie and people didn't care about those things back then. Or never told me they did. Now it annoys me. Any way to fix this in CS4? Keep in mind I know next to nothing about the program...>.< I used to know how to solve this! I did. What happened to that?

Also, all of my output videos come out with black bars surrounding them. Like, on all sides. Like my video is trapped in a little box. It wants out! What did I do wrong, and how can I fix it?

Edit: Adding a screen capture of what I mean. I've outlined the black bars in white. This clip is also from widescreen source, and I believe my adobe is autocorrecting somehow, as I didn't so that. I am pretty sure it's gunna end up looking weird if I don't like...figure out what the heck its doing.

I am completely tone deaf when it comes to aspect ratio issues, but my beta has been kind enough to point out that mine are wrong, and after some research I have run out of ideas for how to fix it. I'm using Vegas 9, and when I export my videos, they are all a little bit stretched vertically. My beta discovered you can fix this manually after the fact (once the video has been rendered) in VLC by going to "Video", "Aspect Ratio", and selecting 16:9. Here are two screen caps to demonstrate the difference:

The initial video.

And a shot after I manually set it to 16:9...

I have the project set to NTSC DV Widescreen, and I have the "maintain aspect ratio" switch unchecked. I've tried exporting it as different file types, but none of them seem to help. The pictures above are from when I export it as a .wmv file. Does anyone know why this is happening, and what I can do to fix it? Help!

Hey guys

I have been co-vidding with someone and having some issues. She says that the video is 'stretched' and has a huge black border. It looks totally fine to me (the aspect ratio is fine and the black boarder is small). I am on a PC, she is on a Mac. I believe what is happening is that my Premiere is set to auto-correct for wide-screen, and her's isn't. How would I change mine? Or is it just a Mac vs PC thing and it will look fine on the internets? Anyone have any ideas?

Thanks

Right, so I've delved through memories, webpages attempted to understand calculator tools, all to no avail, so I'm hoping that somebody here might be able to help me out.

I'd like to make a vid using different avi sources (fandom being Star Trek).

The majority of the footage (TOS series) would be from avi files with a resolution of 512x384, which as I understand it, just means it's an unusual resolution, but still an AR of 4/3, right?

The problem arises from both of the film avi files I have being of what I assume to be... odd aspect ratios. (Resolutions being 720x304 and 704x304 respectively. In my very, very basic understanding of ARs, I'd assume that means their ARs are 2.37:1 and 2.31:1 respectively, but I suspect I'm missing a whole new level of complexity here.)

Obviously, I can't just chuck'em in like that - or resize them, as I want to maintain the proper AR of the film files, just crop them to make them fit the series resolution.

I do my vidding (well, the 2 vids I made years ago) in WMM, and would like to stick to this, if at all possible. (Computer system not being the best and I suspect it wouldn't cope with high-memory requiring programs, and neither would I!)

I have a copy of Total Video Converter, however, which appears to include functions for not only resizing, but also cropping vid files.

And I cannot for the life of me figure out how to go about the cropping. Do cropping numbers in such programs correspond directly to pixels? (Ie, would I just have to, in simple terms, deduct the amount of pixels from each side to reach the equivalent ratio of the main source of clips manually? Also, given that the height ratio of the film files is less than that of the series files, would I first need to resize the film clips and then crop top and bottom accordingly?

Or is there, by any chance, some neat simple program out there that can simply give me the values required for cropping if provided with the respective source and target resolutions (widthxheight)?

If anybody could shed any light on this, it would be hugely, hugely appreciated, because this differing aspect ratio thing is seriously doing my head in. *makes puppy eyes and offers intarwebs brownies*

Hi all,

So, new vidder and new poster here - I've got exactly one vid under my belt so far, so I've got a long way to go ;) - and I'm looking for advice about how to pick between sources, when you've got two choices of poor technical quality.

I've got two copies of the same source material, and neither is 100% usable by itself.

Copy A - has nice bright colours, but is cropped (a la cam copies of cinema releases) so as to lop off the top and left side of the frame. For most shots, this isn't terribly important, but there are a few shots I wanted to use in the vid I'm working on, and they lose a lot of their impact (eg half a facial expression is missing, that kind of thing). Not the greatest image quality, but pretty watchable on most frames. 704px x 336px aspect ratio (wtf).

Copy B - noticeably desaturated and rather dark; not unwatchably so, but definitely worse than Copy A, and worse than the original source (which is mostly bright and colorful). Apart from the desaturation, image quality is higher. Uncropped, and a sensible aspect ratio - 640px x 272px, which is 2.35:1.

Bear in mind that this is for a property where high-quality source is not yet available, so people won't be expecting DVD- or even TV-quality from a vid (I hope) - and in fact there's already been at least one widely-popular vid in the fandom using source of similar quality (although less stupid cropping) to my Copy A.

So, I'm trying to decide: do I do the entire vid from Copy A, and just put up with or work around the scenes that are significantly impaired by being cropped? Do I do it all from Copy B and accept the loss of bright color, which may spoil it for some viewers? Or do I use a mix of the sources, and try and straighten out aspect ratio & color saturation mismatches as I go? (I'm using iMovie 09; I'm not entirely sure what it's capable of yet.)

Any advice you can give would be most welcome!

Okay, I will freely admit it. I have trouble telling when the aspect ratio is wrong, unless it's on a big screen. When it's on my laptop, it all looks pretty much the same to me. So I am seeking to have my eyesight re-educated, and now is a good time as I'm finishing up two vids and starting two others.

EDIT - Since there was some question about the original aspect ratio of the Highlander clip, I've substituted a Sentinel one.

Recently my husband and I were in Bestbuy looking at the widescreen tv’s and we noticed something odd. All of the movie clips they showed for display had different aspect ratios, even though all the tv’s were widescreen. One clip fit the tv screen perfectly and the others had black bars of various widths along the tops. We asked the sales lady about it and she said that even though television widescreen format is officially 16:9, movie widescreen format has not been officially set. She said the movie director gets to decide what AR to use, and they can make it anything.

I was wondering if this is true, and what this means for us as vidders. For example, I have used the AMV resize calculator to resize my file after cropping off the black bars. But if my clip size isn’t 16:9, how do I correctly resize the image? How do I know what AR it is?

I'm making a vid and I've ended up with a mix of 4:3 and 16:9 clips. In the past, it's usually been a majority of 4:3 and I've converted the others to that format, but in this case, I want to use the letterbox format. So - what are your suggestions for the best way to convert these clips to letterbox without messing up the aspect ratio?

To coincide with the Vividcon 2007 Tech Panel of Doom, I developed a number of methods for people to help them with calculating aspect ratios. All of the following methods work in basically the same way computationally, so the only difference is which you prefer to use.

Aspect Ratio Calculators

Flash calculator

Excel Spreadsheet

Google Spreadsheet

pdf worksheet

To use any of the above you need to know:

The size of the clip you want to resize.

The source type (PC, NTSC 4:3 etc)

The target type (PC, NTSC 4:3 etc)

One of the dimensions you are aiming for (width or height)

Example use: resize all of your clips from different sources to have a height of 480 at NTSC 4:3 and then crop any that are wider than 720 (pan and scanning the footage to fit an NTSC dvd frame).

The above tools are in part thanks to

trythil and his excellent and actually much more advance AMV Resize Calculator which works fine for me but can be a little complex for intermediate users.

I recently found out about how you can change the aspect ratio in WMM2 and I was wondering if I could rip my DVDs in a 16.9 ratio without it looking stretched out. How do I know if I can do that?

Also, are there any good tutorials out there about DVD ripping? I have only used one that deals with VirtualDub and AudioSync and I'm looking to find others just to see which works best.

Thanks!

I've probably scared off more than a few people with the subject -- really, who wants to talk about aspect ratios? -- but I'm in a bit of a quandary. There's lots of discussion about converting 4:3 to 16:9 (or vice versa), but what about 2.35:1 and 16:9?

I'm on a Mac, so I'm using MPEG Streamclip to convert my VOB files. The majority of my footage is 16:9, but I have four clips that are 2.35:1. Ideally, I'd like to convert those to 16:9, but I can't even begin to guess at the the settings. Does anyone know how to convert from 2.35:1 to 16:9?

If there's no way to do this with MPEG Streamclip, my other idea is to scale the 2.23:1 footage up in Final Cut Express, so that those annoying black bars effectively disappear. I think that would work, but I'm not completely certain.

If you could offer some insight, I'd be very much in your debt. Thank you!

I have a bit of a surprising dilemma with my new video to do with mixed aspect ratios.

I'm used to this, I've had to deal with them many times before with amvs but with movies this issue becomes trickier due to the relative quality of the images and the difference in framing of animation vs live action. I'm using a lot of sources and some of them are 35mm and others are 16mm sources. In less technical terms this means that some are uber widescreen and other are not-so-uber widescreen (2.35:1 vs 16:9)

I'm not a fan of having parts of a video have letterboxing, so I tend to conform sources to one aspect ratio and stick with that for the whole video. This leaves me with two possibilities:

1) Crop the left and right of the 35mm movies and make everything 16:9
2) Crop the top and bottom of the 16mm movies and make everything 2.35:1

I'm not sure which is going to be best. The former probably safest in terms of keeping what I want in the frame (I wont lose eyes or mouths on close ups, for example). The latter maintains the glory of the (undoubtedly prettier) 35mm movies.

So, which should I go for? Cut off the tops and bottoms or cut off the left and right sides?

Okay, I've never done a high-res vid before where I had to correct the aspect ratio. Now I'm doing that, and it's IRRITATING THE SHIT OUT OF ME.

This is going to be hard to explain:

( WHINE WHINE WHINE WHAT THE HELL ARE THE RIGHT FILTERS FOR FIXING THIS PROBLEM??!?!? )

For

morgandawn, and any Mac vidders who are vidding with ripped DVD letterbox (16:9) source and iMovie:

If you are having trouble with aspect ratio on your clips, you can export the clips with black bars at the correct aspect ratio for iMovie by using the program

morgandawn recommended a while back, MPEG Streamclip. What you need to do is choose the following settings:

Export to Quicktime-->
Compression: APPLE DV/DVCPRO - NTSC
Frame Size: Custom-->720 x 360
Cropping: click checkbox on-->set values as: Top = -60, Left = 0, Bottom = -60, Right = 0
Make Movie

DVDxDV does not have an equivalent setting. Hope it helps someone. :-)

Some DVD authoring programs (IDVD, Ulead) cannot handle both 4:3 and 16:9 (widescreen source).

On some m2v files, the 16:9 screen images are squished vertically to fit the 4:3 format. In the past I was able to manually import the m2v file into my editing software, adjust the widescreen (make the image smaller) so it fit back down into a 4:3 frame and render, then re-export. This takes too much time to do for each vid.

is there a setting we can shoot for (Final Cut or Adobe Premiere or TMPEGEnc) that will export 16:9 images so the widescreen source is pre-adjusted to fit into the 4:3 TV screen?
