Bollox...

I've realised why the quality of the SL videos I've uploaded to YouTube is a bit naff. I have a widescreen laptop, which is where I've tended to do the initial capture (using FRAPS). I then edit and mix down using Audacity (for the audio) and Windows Movie Maker for the video. I save the resulting video in 4:3 aspect ratio 640x480 resolution movie file, which is what gets uploaded to YouTube.

The change in aspect ratio compresses things sideways and reduces the quality enough to make text unreadable.

I'll do better in future... by capturing on my other screen which has a 4:3 aspect ratio.

Sorry.
