photos in DVD format
Hello there,
I’ve created a video with both combination photos and videos.
The movements and the clarities of the photos look good
when it’s in wmv.However, when I export it in DVD (mpeg2) format, the photos part look pixelised and the movements are not smooth anymore- it looks a bit like when you move too fast in video, which the details of the video can’t be seen clearly.
Sorry, I’m not at good explantion. However, the “video part” of the video looks fine- even if the speed of movement is much faster than photos part.
Is there a way get around it? this needs to be presented in a conference and they only have dvd player to play it. The “photo part” really look quite terrible.
Please advice.

How big are the photos? If they are 3, 5, 8, 10 megapixel photos then you are asking Vegas to resize these down to less than 1 mega pixel which is what DVD resolution is. You will get much higher quality if you resize the photos with a photo editor like Photoshop before you use them in a video. NTSC DVD is only 720×480. None of your photos should be larger than 2x that (1440×960).

Hi John,
Thanks for the tips- it seems better in terms of the pixelation or the “sparks” effects when it’s moving – but the whole pictures seem less focus now.
The photo originally was 1500 pixel and now I’ve reduced it to 720 pixels.
But the dvd is going to play in a 32 inch monitor which is 1366 x 768 pixels, and I wouldn’t have a chance to test before hand.
Should I keep the original resolution of the photo then?
Thanks

In addition to the other advice, you might try setting your project properties (and rendering to) progressive scan rather than interlaced.

Yes, if they are only 1500 pixels wide that is fine. You said that you added “movement” to the pictures. How did you do this? Pan/Crop or Track Motion? If Track Motion, that’s the problem. Always use Pan/Crop to maintain the highest picture resolution.

thanks mary 🙂

it was pan/crop as each individual photos has different movements.
I do notice the photos qualities have been reduced more than the videos.
Can I assume vegas processes photo and video differently in a way?

What was the original quality of the video? Was it HD 1920×1080 or SD 720×480? If it was SD then yes, the 1500 pixel photos were reduced more than the 720 pixel video which wasn’t reduced at all.

Well… it doesn’t have to make “video” out of the video. But it does have to make video out of the photos. So yes, it is processing them differently by the fact that they are still images and not video to begin with.
