Greetings,
I am not sure how many other times this may have been mentioned in this forum (David Reece has alluded to it for sure) but I think it needs to be shouted from the mountain top. DO NOT, repeat, DO NOT use VBR Variable Bit Rate while rendering your project.
I made a rather lengthy response to a post on this subject yesterday, Jan. 4, 2004, and basically after what I discovered last night you can ignore what I said except for the fact that the Anti-Flicker Filter appears to work sometime if you render with VBR.
After rendering at Constant Bit Rate all of my flickering pictures were gone and what was left were nice clean pictures using any transition I wanted.
I even rendered with the Anti-Flicker Filter turned off (I've always wondered why there is an option for that. Does anybody want it to flicker?) and there was still no flickering.
Details for setting CBR:
Create Video File
Options
Video Save Options dialog appears
Compression Tab
Video Settings-Video data rate drop down SELECT CONSTANT.
Set the rate you want for quality. Higher rate=better quality=larger file size.
For me, the fix is in.
Hope it works for everyone else.

Flickering Fix ?!?!

Hi Gary
Which format did you use
For a while now I have been able to make video/slide shows etc without the dreaded pixel pulsations.
The settings I use for all my projects are:-
PAL (25 fps)
MPEG files
24 Bits, 720 x 576, 25 fps
Lower Field First
(DVD-PAL), 4:3
Video data rate: 8000 kbps
Audio data rate: 224 kbps
MPEG audio layer 2, 48 KHz, Stereo
I change the bit rate to match the length of video.
A few weeks ago I was successful
in making a test project with the dreaded pulsating pixels, by using Mpeg format instead of Dvd format.
There’s not a lot of difference in the settings:-
PAL (25 fps)
MPEG files
24 Bits, 720 x 576, 25 fps
Lower Field First
(MPEG-2), 4:3
Video data rate: 8000 kbps
Audio data rate: 224 kbps
MPEG audio layer 2, 48 KHz, Stereo
But a big difference in the final product.
Why do we have the options of :-
Mpeg 2,
Pal/Ntsc Dvd
I use Pal_Dvd, and stay well clear of Mpeg2
And whats the difference between the two
This subject has been on going for far too long, it’s about time a definite solution was found, maybe this time
All the Best Trevor

Trevor,
Unfortunately, the "Blame it on Mpeg" theory doesn't hold water either. I have been capturing directly to mpeg2, editing mpeg2, and burning to mpeg2 forever.
My Capture, Project, Video File, and Burn properties are all the same:
NTSC drop frame (29.97 fps)
MPEG files
24 Bits, 720 x 480, 29.97 fps
Upper Field First (for analog capture)
(MPEG-2), 4:3
Video data rate: Variable (Max. 8000kbps)
Audio data rate: 224 kbps
MPEG audio layer 2, 48 KHz, Stereo
Almost every problem that I encountered with Video Studio was traced back to default property settings that did not match my capture properties. My problems stopped when I began to set properties manually every time.

Hi John
I also use the same settings from the start to finish,
Knowing my burn settings allows me to set my capture.
But if I capture to Dv_Avi, After editing I convert to Dvd_Pal (Mpeg 2) file using the required burner settings.
When I tried a test slide show using Mpeg 2 instead of Pal-Dvd I got the pixels pulsating.
I will have a go at creating a couple of slide shows tomorrow, using the different settings.
My system is working fine at the moment, trying to make it misbehave is as hard as curing problems.
Again this problem has been ongoing for ages,
All the Best

Gang,
I knew ya'll would gig me for my lack of details but I was so excited about my problem being resolved I wanted to get the word out. Will try to respond to questions and fill in some details.
I am in the United States so I use NTSC, here is why
http://www.high-techproductions.com/ntsc.htm
I render to MPEG-2 because that's the file type I use to create chapters in DVDs.
JC - In my project, the only thing I changed between flickering pictures and non-flickering pictures was going from VBR to CBR, that's it. The difference was quite dramatic.
One thing that is a variable in all of this is that there appears to be certain pictures where flickering / pixelation is triggered. Green foliage and lines seems to be what sets it off for me. As I mentioned ealier, I was getting desperate so I tried some of the same pictures that were giving me problems in Pinnacle Studio 8. There doesn't seem to be a VBR option in PS8, just a resolution option, anyway, when rendered I did not have flickering just nice clean pictures. I got the same quality in VS8 on the same pictures when I used CBR.
I am working on a rather large project of a band trip to Orlando, FL (Disney) that will be distributed to others on DVD. The flickering on some of the pictures was so bad I didn't feel comfortable releasing it but now that I have a solution that works for me I am much more confident in my final product.
I made an Image file and included both versions of rendered MPEG-2 files as seperate chapters. Created a DVD from the image file and played it on the DVD player hooked up to the TV and the CBR chapter looks great.
If you haven't experienced flickering video then I could send you some pictures that definitely did it for me.
