I've filmed some stuff in HD and have sucessfully downconverted to SD to go onto a regular DVD.
When played on a widescreen tv and on the computer I notice very subtle jaggyness on the straight lines. (bars,railings, brickwork Etc.)
The real problem is that when the camera moves quickly everything gets very blurred and hard to see. (not blured as in out of focus, almost as if the picture breaks up a little) but returns to fine on the still shots
The problem isn't huge but I was wondering if there was a solutions to this to remove or further reduce them the effect. Perhaps a field order or de interlacing.
