Got one for the Pros ... Got a job Converting a bunch of PowrPoint Presentations to DVD and I have converted the image files Sucessfully enough to uncompressed .TIFs .... the Problem is that a lot of the image files are of Spreadsheet like images and these images have alot of Horizontal Lines in them and when put them in a slide show in DVD Architect or as an .avi rendered to mpeg 2 ...I still get these jitters with the horizontal lines..
I have tried the deinterlace filter in vegas and uping the bit rate in DVDA and still get a flicker at the horizontal lines I got about 30 hour trying to figure it out ......Anybody had succes with this kind of situation.... this one has got me stumped ...........................ecoman

Why would there be a limitation of DV ?? Vegas will edit Standard NTSC 720 x 486. If it is not captured in DV- then it can be edited in formats other than DV. Also- the software I stated will not need to go to an edit system- It is a stand alone PPT to DVD package! Not sure what your comment about DV is??? Maybe I missed your issue?

Ecoman's problem is the jitter on thin horizontal lines.

Sorry....that is a problem in powerpoint. People are always building the things for computer monitors...not TV sets utilizing scan lines. I should have read the problem better- please forgive. There is no way to fix the "Thin Line" syndrome without rebuilding those bad areas- the lines are to thin and are jumping between scan lines causing the jitter. The lines need to be made bolder. When I had this problem with one of my clients I suggested a few options... I can rebuild these "bad" slides at xx cost, they could rebuild the slides or they can opt to keep the slides "as-is". There is no easy fix

1 - Copied plain old Gridlines from EXCEL SS into PowerPoint

2 - Saved PP slide as GIF

3 - Imported GIF into Vegas

4 - Onto T/L

5 - Rendered to new track - JITTERS in some of the horizs

6 - Applied Gaussian Blur 0.001 - Jitters gone!

7 - THEN played with different slder settings of Sharpen fx, anything from 0.030 to 0.809 . . around 0.810, this is when I started to get the jitters back.

I even repeated the same with actual figures - Jitters gone!

Conclusion . . Jitters hroizontal or vertical are stabilized . . it's working with PAL, I'm looking at it now . . on a PAL tv through the External Monitor Preview . .. seems/appears rock solid to me . . any good? At least this way you've got a way of "controlling" the jitters. It may not be "the" professional way of doing things . . but it does appear to work . .Anyways . .it's way way better than what I had . . .

I really don't like to be beaten by a graphic!!!! - I wont have it .. I'm definatley off to bed now . .

Laters ..

If you have Photoshop you could try this (and it may be possible in other gfx packages as well).

apply motion blur at an angle of 90 degrees with a distance of 1 pixel, it's an old trick but I've always had good results with it, if it's still flickery - do it again. Hope this helps - good luck.

Hey Grazie ...
Your technique of the .001 Vegas Gausian Blur for those thin Power Point lines works very well ...
There is a slight hit on the Resolution... but the trade off is worth it ....versus staring at nerve racking jittering stills...
Thanks Again...

Brill! Are you gonna use it? Don't forget to use some Sharpen Fx . .I know it "seems" a bit, well, contradictory .. but just give it a go .. Move the Sharpen Fx until you start to see the "flicker" again .. go back a few numbers .. yeah? You can get some really good control over those little Flickers .. yeah?

Thanks for getting back, I was hoping you gotta a solution . .

Grazie

>Don't forget to use some Sharpen Fx

I've also used combinations of Blur->Sharpen->Blur->Sharpen-etal. Not intuitive, but it can work.

However, IMHO the Sharpen Fx is nowhere near as good as the Convolution Filter. I don't have my Vegas handy, but in the Convolution Filter there is a preset called "Sharpen" or something. Try that instead. You can adjust the settings by altering the numeric value in the "center". I go to 25 for major sharpen and 35 for minor sharpen for normal use, but your needs are probably different.

You can also create two duplicate tracks: In the top track, add the Convolution-Sharpen. Keep the bottom track untouched. Then adjust the opacity of the top track to taste.

---
Actually, you could use the two duplicate tracks without sharpen: Just add the blur to the top track and adjust the opacity. Might give you the extra control you need.
