Interlace means that if anything changes from 1 field to the next then you will see 30 Hz 'twitter' (25Hz PAL). You can help it by: 1) softening the title in Photoshop, I like to use a 1 pixel vertical motion blur. 2) ensuring the title moves an even number of pixels per frame OR rendering the motion without interlace (i.e. on a frame basis) Perry Mitchell Video Facilities http://www.perrybits.co.uk/ unedited jpegs save differentl - "Perry" tmb posted: >This is interesting... 1 Load a jpeg into a graphics program 2 Don't edit it in any way 3 Save it under a different name My results... 570k original jpeg 205k as saved by MGI Photo Suite 285k as saved by Photo Shop 5.0 872k as saved by Microsoft Photo Editor Groan...< jpeg has a variable compression ratio, probably most of these applications save jpegs with different default ratios and therefore data size.
