When I placed a 48 MB MP3 (45 minutes worth) in one of the 6 folders I had on my VCD configuration it fills up my disk at 11 GBytes during slide creation. Before adding music the slides show (including the PC .EXE file) already used 589 MB. What format is the sound converted to? How can I calculate how much sound + pictures I could fit on a VCD? (already calculate that my cameras stills come out to around 1700 pictures per CD at 4 seconds per slide). Thanks, D. |

Hello 1700 pictures will fit without sound. But with sound 1700 pics at 4 seconds = 113 mins which won't fit. You can only fit about 60 mins on a CD.

OK, I still need a little help understanding here. It is the length of the slide show that will drive the additional size create by the sound then? If I did 1700 pics at 2 second each it would be 56 minutes. If I add then add MP3 file that is exactly 56 minutes long - should this fit on one disk? Or is there an overhead to adding the music? I am not a VCD expert, but it seems like it shouldn't add any overhead if it is VCD - SVCD has variable bit rate which might make a difference when adding music. It would be great if XATSHOW would show a real time graph of my remaining space so that as I add elements, I could see what was happening (and for it to account for the PC slide shows also being on the disk). This would allow me to know when to move one or two months worth of photos to the next VCD.

If you make a show that has 1700 slides and is 56 minutes long not only will this make a HUGE file on your machine, but your viewers will likely die a horrible death from "slideshow overdose." What is it you are doing that requires a 1700 slide show?? |

How would I calculate the PC slide show into the equation (since I am using it) ? I guess what I am driving to a formula that I can calculate how many pictures with music and with a PC slide show can I fit onto a disk. I can do the calculations, if I know the relationship between the sound file and the size of the disk. It sounds like it is zero overhead to the VCD - but what overhead does it add to the PC slide show?

Yes I understand this - but I can easily calculate the average for my camera and photo types by building a 1700 or 1200 slide disk and divide by the total CD size (even with the PC slide show included it would average out). I am not even looking for the total, just tell me what overhead is added to the VCD and the PC slide show by the music, I can calculate my own averages for the entire composition. The results I am getting from our last conversation are confusing me - I have a VCD that is much less than an hour and added a 45 minute music file: 1) I put together a disk with 6 shows, total of 1200 slides with a PC slide show included, the image file comes out to 415 MB. 2) I edit the same XATSHOW config and add a 45 Minute MP3 (48 MB) to the menu root, deconfigure the PC slideshow and I get a warning that the disk will be 2000 MB. 3) When I move the same music file to one of the slide show directories I get no error, but XAT fills my harddrive up building the disk. I guess I can't understand from the results how sound is supposed to work and the help documentation does not explain it. So I can't even get to any type of reasonable estimate of whether cutting my 1200 picture disk down to 600, 400, 100 pictures would give room for the sound. Thanks, D. PS - A couple follow up questions: *) If I add sound that is shorter than the slides, does the sound file get repeated, or does it just end? *) Is there a way to add a sound file that applies to the entire disk that has more than one slide show on it? _________________________________ Darwin Sanoy Principal Consultant / Instructor DesktopEngineer.com WindowsInstallerTraining.com Sent: Monday, February 10, 2003 5:17 PM Hello Darwin >How would I calculate the PC slide show into the equation (since I am >using it) ?

This is a critical factor. Chris. |

The delay is 4 seconds, but I'm not sure you are understanding my question. Here is a follow up question - when a song repeats, do the bits for the song get duplicated on the CD, or are they just referencing the same copy within the structure of the VCD? Does the PCSLIDE Show act the same (duplicating song bits versus referencing existing ones?). I have started my own experimentation to determine the numbers for my situation. I am finding sound dramatically increases size: A 345 Slide CD: - 137 MB VCD with no sound - 365 MB with sound (unique songs for each minute of VCD) - 16 MB PCSLIDE show without sound - 36 MB PCSLIDE show with sound PC slide show amounts can simply be added together to get the numbers for a VCD that has both on it. I would like to suggest a feature that predicts how many photos could be placed on a VCD. I could envision it using the following techniques / algorithms: *) Ask me to have a certain number of sample images for my average composition (assumes that many users will be using the same camera and similar picture types - but averaged across enough photos this should be able to be relatively accurate. *) Perform benchmarking of those images (most likely creating sample temporary shows and tracking the time and size). *) Report the approximate number of pictures per disk for the following composition scenarios: - VCD slide show(s) only - VCD Slide shows w/ sound - VCD slide show(s) only w/ PCSLIDE show - VCD slide show(s) w/ sound and w/ PCSLIDE show - PC slide show only - PC slide show w/ Sound You could output it as a slider scale in MB that shows each of the above on the slider and then shows the capacity of 650 MB CD, 700 MB CD, 2.4 GB DVD I would be great to let it do the calculations and then let me dynamically change the following items and it could change the graph: - number of slides - length of delay - with or without music - with or without PC slide show - with or without full archive copy (when the feature becomes available) Optionally this procedure could predict how long it will take to build a show on a given PC since you could benchmark the time as well. *) Also a pie in the sky feature idea - what about building a plug-in for Canto Cumulus - now that would sell like hotcakes - especially if all the above prediction algorithms were built in so I could have XATSHOW build a full archiving system that included musicfied VCDs with canto cataloged images. Anyway, please drop a line on the issue of whether song bits are duplicated - which would mean there is no benefit to purposely configuring shorter, repeating songs - or whether repeating songs cause the same song bits to be referenced multiple times.
