Hi,

I made a 14 min. video with a lot of stills and some video clips, applied the anti-flicker filter and noticed a small jump at the end of each transition. This was livable until I tried to insert this video into another project. I did the Share - Create video file option and converted it to both DV type and MPEG2 files. When inserting either of these files into another project the video pulsates to the audio and the pictures pixelate very bad. Watching the MPEG2 file I just see the small jitter at the end of the transitions, but when put into another project and rendered the pictures all pulsate between clear and pixelated.

Here is how I was rendering it.
MPEG files
24 Bits, 720 x 480, 29.97 fps
Lower Field First
(DVD-NTSC), 4:3
Video data rate: 5000 kbps
LPCM Audio, 48 KHz, Stereo

I noticed another thread on this here:

I am using VS8.
Can anyone tell me if this problem is fixed in the most recent version? I will upgrade if this will fix the problem.

What you are describing sounds very much like the problem in this thread:
smart-renderer produces shortdistortions with titles

I finally fixed the flickering/pulsating problem after hours of trying various things. Turning off the "Perform non-square pixel rendering" option fixed the problem.

Turning this option off fixed the flickering problem, but created another problem at the same time. I quite of few titles with white text on a black color background and the text all shifted to the left and isn't centered anymroe. It looks fine, centered in the editor, but it is off pretty bad after it is rendered. I tried moving the text to the right more in the editor so it looked off centered to the right and re-rendering and it was still off center to the left. Anyone have any idea how to fix this? I also tried both the multiple title and single title options.

If I turn the "Perform non-square pixel rendering" back on my titles are all centered again, but my pictures flicker.

I had the same problem when I turned off "non-square pixel" rendering. It appears that Corel/Ulead did not account for text not formatting properly with this option turned off. I suggest offsetting the text in your titles again and select left justified text instead of center justified text.

This problem continues with VS Pro X2 . . . turning off non-square pixel rendering fixes the off center titles, but now I've got the flicker issue! <screaming>

Geeez, seems like they would have fixed it by now (after 4 version releases since this thread started!) . . .

What happens if you turn off Non-Square Pixel Rendering, then render that to a video file. Then import that video file into your project and add the titles.

Not sure I follow you, Black Lab . . .

Are you saying to render it with the color chips in place, but no titles and then import that and apply the titles to the color chips in the video?

Yes. Finish editing your video, but without the titles. Turn off Non-square pixel rendering and render your project to a new video file. Import that video into a new project and add the titles. Now turn on Non-square pixel rendering and render it to a new video file.

Was about to try your suggestion but attempted one more thing - it worked!!!

I render the video using the Non-square pixel turned ON, but I render it to a wmv file. It's perfect! No off-center titles, no flickering of the title text!! I tried this with several new titles in new projects and it works EVERY TIME!!!

Why does it work? Who knows and who cares!!!

Thanks for all your effort and support in trying to solve this issue!

Who knows and who cares!!!

Who cares? Anyone trying to burn to a DVD, because the WMV would have to be converted to MPEG-2. What happens when you do that?

Sorry, Black Lab, I didn't finish my thought and you were exactly right in asking . . .

I render this to wmv, 720x480 at 8,000 kbps CBR and stereo audio CD quality. I then take that wmv and insert it into my main project and convert entire thing to mpeg for DVD.

The high quality wmv shows no degradation in resolution. Haven't tried it at lower CBR to know where the line is good vs/ bad quality. Doesn't matter to me as long as what is used for the mpeg is good quality since the wmv isn't the final product.

I render the final mpeg and then use a 3rd party app for burning DVD.
