I read a tutorial once about making a jacket image for a DVD using all kinds of other software like Quicktime and other freeware. I never tried it myself.
Basicly getting a single frame mp2 was the objective. Has anyone tried this from Vegas to see if it would output the correct format?
I've done website graphics with Vegas, simply exporting the frame as a jpeg and then cropping in Photoshop. I don't know that the 72dpi image would be high enough quality for a good printout, however.
The jacket image is a DVD spec designed to let DVD players display a custom image when the player is stopped. This would be instead of the normal player brand logo such as JVC, Toshiba, or Sony. For instance, the origninal X-Men DVD v1.0 will display the metal X-Men logo when you stop a jacket-image equiped player.
The image can actually be anything, but was intended to be an indication of the disc.
One of the new Sony DVD jukeboxes will scan a disc for a jacket image and then use that to allow you to browse the loaded DVD's by picture thumbnails in addition to word titles.
I've messed around with this and not yet been successful.
I think the Jacket Image specs must be from some authoring facility. They seem to describe how they want the image and files sent to them before they convert them to the mpeg file format that the DVD players expect.
The file names and descriptions in your second link seem to match what I see on my comercial DVDs.
If there is a way for Vegas to do this, I'd sure like to hear about it.
Sorry to say but I don't believe DVDA will let you insert one, I was a bit confused at first, I thought you were trying to print a piece of paper, to put inside the case, with an image from the video!
