DVD Quality - again!

I have read several threads on DVD quality and I am sorry to raise it again but I would like some advice on optimising it. I am editing a project with video clips and some extensive slide show regions. I tend to use motion in the slide show. If I make an AVCHD disk the results are excellent. I also want to make some ordinary DVD's recognising that they will be much lower resolution. When I do this, I get a lot of flickering artifacts along edges in the slide show - some images are worse than others. If I save the AVCHD file to disk and then convert it using ConvertXtoDVD, the resulting DVD is much better and acceptable so I think the problem is in the DVD rendering in PowerDirector. But I would prefer not to use a second program and a re-rendering. I have tried turning off all hardware acceleration and creating MPEG-2 files with a custom profile but I cannot get rid of the flickers. Is there anything else I should try?

Hi,
Try lowering the burn speed on you burner..some of the new burners the maximum burn speed causes jerky behavior when burning at maximum burn speed, lowering it may correct this.

Hi Jim
Many thanks for the quick suggestion. I don't think that is the problem, though as the flicker is present when I save to folder on my hard drive.

Hi Philip,

You mean even you customize the MPEG2 bitrate to very high, the quality is still unacceptable?
How about import the good AVCHD output, then produce the MPEG2?(do the same thing as you do on ConvertXtoDVD)
Did you try to produce H.264 with the same resolution as MPEG2?(ex. 720x480)
How about the preview quality?
Do you use 32bit or 64bit OS?

This thread is talking about similar thing and provide some setting suggestion, maybe you can try it~

Sorry that so many questions.

Thanks.

Hi Will
Thanks for your reply. I think I have more or less sorted my issues which, I guess, are largely due to my inexperience in video editing.

My tests showed that the video and still pictures were fine but I got pronounced moire effects and jittery edges when I pan/zoomed the still pictures in a slide show. This was particularly bad when I used the trick of making a video clip from the slide show wizard which I did in order to be able to alter the timing of the slides. I believe the problems are due to the interlacing done for the DVD standard.

My solution is to use the best still pictures (large) that I have and to manually construct the slide show. I use modest pans and zooms and I alter the duration of the sequence by adjusting the slide durations. Then on rendering, I get pretty good results.

Thanks for the interest,
Philip

Looks like the problem is solved.

Congratulation~
