Slideshow PAL DVD
Hi, I making a slideshow in premiere pro to burn to a PAL DVD and need some help. Like how to prepare my images before importing to premiere?
I know NTSC is the best choice because the original pictures is 5237x3491 but I want PAL. I don't want to cut anything on my pictures if I don't have to. I also want the correct aspect ratio. If I scale my pictures in photoshop to 592x576 (16:9) or 792x576 (4:3) I think I have to put black bars up to 720px. But isn't there an easier way? PAL 16:9 anamorphic widescreen 5237x3491, 864x576, 864/1,4587 = 592,3082196476315 = 592 = 592x576 PAL 4:3 anamorphic widescreen 5237x3491, 864x576, 864/1,0940 = 789,7623400365631 = 792 = 792x576 |

Not without cropping into the pictures. Your source photographs are approximately 1.5:1. Scaled down and encoded for 4:3 they'll have black bars above and below (not that much, though). Scaled down and encoded for 16:9, they have (larger) black bars on the two sides. There's no way around it.

As for which DAR (4:3 or 16:9) is the better choice, it's pretty much a wash. Theoretically you should get very slightly better image quality by encoding for 4:3. Last edited by manono; 6th June 2011 at 18:07. |

Thank you!
I found a way to do this in Premiere Pro. In the settings "Default scale to framsize". Seems like I get 25px black bars above and below. But now when I compare the pictures in the computer it seems like Premiere Pro made wrong aspect ratio. The pictures also got bad contrast. But It seems like everything looks better on the DVD. Do you think it's better to do this by my own? In that way I need help with how to crop the pictures in Photoshop. Which resolution to get 1,0940 and 1,4587?

And I don't think you want 25 rows of pixels above and below. 24 each would be better. Or 26/24. Don't use odd numbers. Quote:
Have you seen the free DVD Slideshow GUI program? It's very good: http://www.videohelp.com/tools/DVD_slideshow_GUI |

It looked like the video from premiere got a 25px bar but it was 26px. I know that I not should use odd numbers.
Thanks for the software! I know that I'm a noob but that's why I'm here asking questions Can you please look at this and tell me what's wrong? 5237x3491 --> 720x480 480 (Vertical) x 1,33 (4:3) = 638,4 / 1,5 (PAR) = 425,6 px tall --> 720x424 720x424 with black borders above and below to 720x576 should look good on a PAL 4:3 DVD.

Thanks for the reply!
Yes, you're right. I need to use 576 vertical lines like this. Then I get the same result as you 5237x3491 -> 864x576 576 (Vertical) x 1.33 (4:3) = 766 / 1,5 (PAR) = 510 px tall (510/16=31,875, 32x16=512) -> 864x512 -> 720x512 (Resized to 720, MPEG has an embedded DAR) Last edited by Blue Star; 10th June 2011 at 09:06. |
