You're spot on, mate - and as you went on to say, I could potentially do this from Premiere Elements, but it does not allow sufficient control over parameters. Basically the only useful output I can get from Prem Elements is an AVI. I then open that AVI in QuickTime to put out MP4 and .mov files. I also output a WMV file based on that AVI using Windows Movie Maker - which, I'm ashamed to say, always does a superb job and the result pretty much matches H.264 for good looks. Steve, you _can_ deinterlace in QuickTime by getting into movie properties -> visual settings and ticking the deinterlace box. Also ticking the "high quality" box seems to do something. However neither of these measures removed the jagged lines completely for me - the best result was achieved by deinterlacing when exporting the initial AVI from Prem Elements. This interlacing problem is weird - it has also started happening when I use a little piece of freeware called SplitCam to turn the mini-DV camera into a webcam for Skype purposes. It never used to do this before. Last night I reset the camera to factory defaults so will see what happens next time we shoot an episode.
