An aspect ratio problem
Posted: 28 Aug 2006 04:21 PM
I imagine these pop up every so often around here, but I can't quite figure out how this works, and I'm not entirely that experienced in WMM. It appears I have a 320x240 (4:3) frame that contains a letterboxed 4:3 video (with the letterboxing stretching the video horizontally into a 16:9 aspect ratio).

Is there some way I can either remove the letterboxing or otherwise unstretch the video horizontally? (If the frame were 16:9, I could change the option in WMM from 16:9 to 4:3, but since the frame is 4:3, that option's already at 4:3 and I can't unstretch it any further. Changing it from 4:3 to 16:9 stretches it even further.)

Any help would be greatly appreciated.

Let me first understand the problem...

Are you saying that the video you have has the video squashed vertically so that the original 4:3 video makes everything look short but wide?

To undo this, you would want to create an effect where the middle 75% of the screen vertically is expanded to be the full vertical height. And the horizontal aspect would be unchanged. Is this correct?

One easy way to do this would be to use Rehan's PIP+ package to create an effect where the video is changed to display 1.0 0.75 and expand it to full screen.

That's precisely the problem. Now, I'm not exactly sure how to solve it like you mentioned. Could you expand, please?

By the way, I just managed to use Windows Media Encoder 9 to do the crop and resize, but the video quality has gone down somewhat. Do I need a higher bitrate?

Okay, here's how to do it as PIP+ effects. First you'll need Rehan's PIP+ package (www.rehanfx.org). Download and install that first.

Next, copy/paste the following code into Notepad and save as pipunsquash.xml in C:\Program Files\Movie Maker\Shared\AddOnTFX

<TransitionsAndEffects Version="1.0">
<Effects>
<EffectDLL guid="{0BEDE179-3361-4eea-9058-11CBB1739D50}">
<Effect name="PIP+ Unsquash Letterbox" iconid="33" comment="Converts squashed letterboxed 4:3 back to regular 4:3">
<Param name="RectA" value="0.0,0,-0.1667,1.0,1.3333" />
</Effect>
</EffectDLL>
</Effects>
</TransitionsAndEffects>


When you are done (and you restart Windows Movie Maker) you'll have a new effect (PIP+ Unsquash Letterbox) that you can apply to your video.
