BluRay DVDs also handle HD, provided you have a BluRay recorder, and a BluRay player to play them back.Computer files to be read on a computer.You can store any file on this format, and images can be stored in any resolution. Basically, this type of DVD can be read on a computer. DVD players (the sort you connect to a TV) can sometimes read them, but usually not. Just to confuse matters, you can also write computer files in this way on a BluRay disk (if you have the appropriate BluRay writer on the computer), but that just makes them bigger (they store more data) - you can still write any type of file to them. Normally the whole DVD is written in video format or computer file format. So if you are creating a slide show that writes to the DVD in video format, and plays as a video on a TV, then you're limited to NTSC resolution on a normal DVD, or HD on a BluRay. If your slide show program creates the slide show in a normal computer file, and it's going to be written to a DVD in compute file format, then it can be any resolution, provided the program creating the slide show supports it, and you're going to play it back on a computer (or you have a DVD player that can cope with that type of file connected to the TV - as I say, most TV DVD players don't). However, I don't know anything about Fotomagic or iDVD (or Macs, for that matter) so I may be giving you incomplete and misleading information! With luck, and expert on those will be around soon to give more info. I am a Mac user and have encountered similar difficulties when trying to create a slideshow. The problem is with the way the Mac software (in your case iDVD) encodes the slideshow into a video. Basically iDVD and the other Mac software that comes with OSX use various compression routines, one of which is to only encode every other scanning line. Thus for UK TV (PAL) 625 lines are the normal resolution (I'm simplifying this a bit) but the Mac video encoding software removes half the lines (so encodes only 312½ lines), thus the soft results. The same applies using the NTSC standard. I found this out by lengthy research on the internet.Īfter a lot of experimenting and testing I found that the best way was to make the slideshow from iPhoto, this retains the full resolution of the original. In your case, if you need to get the slideshow onto a DVD, you will need to consider some other DVD creation software. I don't know if Roxio's Toast will work better ? This is where my knowledge is exhausted but researching the internet would bring some useful results. I run a Mac and have just experienced all this same frustration in trying to prepare a slide show for an exhibition. I too prepared a very acceptable quality slide show in Fotomagico, but all my attempts to reproduce the slide show in DVD format ended up with lousy sharpness loss and poor colour etc. I tried iDVD, Quicktime and Roxio Toast all with the same results. Leaving my laptop hooked up to the TV Monitor at the exhibition was not an option. The answer we came up with was particularly simple.
