Hi All,
So with only a few days to spare the pfd is complete. all the links work great, looks pretty... BUT- i am still embarrassed and sad about the load time. We have to deliver this on a DVD-ROM which kind of bites because people have different computer processing power- but still... When you click on a video to open it it takes anywhere from 6 to 20 seconds to open. When you click on a link to open a video on a different page- it jumps to the page nice and speedy quick- but again- you have grown 20 seconds older as you wait for that piece of the video to begin (thats a minimum 2.2 hours of waiting to look at the whole thing in case you were wondering) . there are over 400 links- and 350 of them are jumping to different pages before they seek to a time in a video. its too sloooowwww. because i am pretty new to the rich media end of acrobat- i hand linked every single one so i dont think i would have time to redo that- but i would if i could get this video to load quicker. (maybe there is even a faster way to link- but i suppose that is a different post) the total amount of space used on the dvd-rom is 1.8 GB and the pdf itself is about 1.4 GB. anyone have any thoughts?
thanks,
melanie

Sorry to hear it's not playing ball, but I'm afraid it's one of the inevitable side effects of the way Acrobat embeds the video data into the PDF stream - when the video annotation first activates, Acrobat trundles into the file and looks for the section with the data in (which may or may not be anywhere near the part of the file that stores the other page content), then it has to extract the data from the encoded format used in PDFs before it can play it back. With a very large document such as yours, especially reading from DVD, these combined effects can amount to quite a delay.

Splitting the document into lots of little chapters would help a bit, as the search for the library would happen faster, but there's not a lot you can do to get away from the decode process, short of dragging the video files in from external sources (and by that I mean websites, as even if they were added as PDT attachments, they'll still be embedded in the stream in the same way. A PDF can't import from the local filesystem, and that means it can't even read FLVs on its own DVD).

As the Flash video system was new to A9, it hasn't really had the opportunity to be optimized for your size of document (which although perfectly valid, is also a very extreme example). If you're going to be working on the project again in the future, we'd be happy to see if there are options to improve the process, but of course that would require access to the material.

Thank you for your response. I am happy to give you a copy of the material. Please let me know how to get it to you. I cant get it on our ftp site as its too large. Its already out the door but I would like to know how to make these more efficient for the next time.
