Picture flutter on VCD

[dennispit]

I have made a VCD containing photos with dissolves and background music. When I show this on my TV via a DVD player I get a slight dithering of the picture near the top of the screen. I also seem to lose some of the edges of the picture. The slideshow was originally mede as an AVI with SSMM and then converted and burned with NERO 5.5 VideoCD option. Can anyone please suggest what is causing the faults and possible ways of stopping these on future discs. By the way the orinal pictures were 640 x 480 pixels.

1) When you transcode give yourself plenty of (black) borders
(the display area differs from tv to tv)

2) If your TV can't handle the default VCD slideshow picture res.
(which is common on smaller/older TV's) encode the picture
using low vcd res.

-> Tmpegenc will do (1) for you (see clip frame)
-> VCDEasy (latest version) will do (2) for you (see tools)

Many thanks 'offline' for your answer. I will try your suggestions. Some of what you say about older TV's could be applicable as ours is about 9 or 10 year old. !!! I don't think this would apply to the VCD files as they still
showed the fluttering when I played them with PowerDVD on computer.

Hope it helps. BTW what do u mean by flutter exactly? Motion not smooth or some flickering in the image?

I mean that the screen image flickers occasionaly in the top quarter of the sceen. It also does this in PowerDVD player.

What was the frames per second of your original AVI file
before you transcoded it?

[dennispit]

The original AVI files were created with SSMM and are at 25fps. They were converted in Nero prior to burning VideoCD.

I have never used Nero's encoder but I have heard it is
fairly poor. You could run a couple of minutes through tmpgenc as a
test to see if Nero is the source of your problem - just use a standard
PAL vcd template and check if the same issues arise. Other than
that I can't think what might be causing the problem.

luck!
