What exactly happens when Premeire “fits” a 2-hour slideshow onto a 1-hour DVD?
I have a 2-hour slide show [yeah, yeah, I’ve heard all the jokes before… 🙂 ] and it is now time to burn the project to a DVD. I can either let Premier reduce the quality and fit the project on a single DVD, or split the project onto 2 DVDs.
Can someone please tell me what exactly happens when the program reduces the quality to “fit” the project onto a DVD?
Is the frame rate reduced? If so, I would think that does not really matter, because I’m assuming a majority of the frames in a slide show are the same.
Is the quality of the picture reduced? I know that it can’t change the resolution (I’m using DV resolution of 720×480). But I would guess that it could change the compression or quality of each photo. (Similar to how you can adjust the compression of a JPEG file in Adobe Photoshop.)
Is the quality of the sound reduced? I hope not, because the slideshow is going to be played on a nice surround sound system.
Thanks VERY much,

There are various ways to compress it to fit, and reducing the quality by increasing compression is the most common. However, if you have a slide show, the compression shoud be very good, and you may very well find that a VBR export will be a lot smaller than you think, with no reduction in quality. Just allow a very low to a medium high data rate, and the very low will be used when nothing moves.
If you did a lot of Ken Burns movement, then it will still require a large file size. But remember, no movement is extremely easy to compress.

Thanks Steven! I have a dissolve transition between each picture. Is that similar to Ken Burns movement? I’m a definite newbie.

No. That means that if you made each picture 5 seconds in duration with a transition on both sides, two fifths of your project has to be compressed lightly to see good transitions, while three fifths is not going to take up much room at all. You might just get away with it on one DVD with a good quality, but you will need to use VBR not CBR.

Steven,
Thanks again. Can you please let me know what VBR stands for? I found the option that I’m using and I can choose from VBR, 1 pass and VBR, 2 pass. I have it set at VBR, 1 pass. For VBR, 1 pass, the Minimum Bitrate is set at 1.5Mbps, Target Bitrate is 6.0 Mbps, and Max bitrate is 8.0 Mbps.
Is there a website that I can go to in order to read more about this stuff? Then I won’t need to bother very nice people like yourself!
Thanks,

VBR = Variable Bit Rate
I am not sure if there is a good website for this. Must be, I guess. I know who the compression master is, so I know who to ask when I have questions, but I don’t know of a page that explains all of the features around encoding for DVD. Perhaps someone will come up with an answer and I can post the link to my site.
There is a bit of good info here: https://dvd-hq.info/Compression.html

Steven, I think the Creative Cow website is an INCREDIBLE resource.
Thank you VERY much!!
