How do I add sound or naration to specific points?

Export you slideshow to mpg/avi. Open it in Multiquence(shareware) or DubIt(free). Record naration or add music to specific points to the slideshow and export to wav/mp3. Import this wav/mp3 into you DVD slideshow GUI project. 

Can I make DVD slideshow GUI work faster with images?

Only when working with animation. In this case large images use up a lot of RAM and will slow down DSG or even make it seem like it has crashed when processing images.  Especially when importing, exporting and processing animation.

The solution is to batch downscale your images in ex.  Irfanview(free) to about the size you need them. Look under  DVD slideshow GUI/presets to see you size (PAL/NTSC/4:3/16:9).  

 Why do HCenc or Media Player Classic hang?


Maybe because you're out of harddisk space(the drive where DSG is installed or the drive HCenc is exporting to) - mpg/dvd files are huge. Or because you're out of ram.


How do I make overlaps between slides?

Use negative transition durations under Slide Settings(right mouse click on slide).

What is 'Duration'?

The slide duration value(left) is the number of frames the slide will be visible before the transition. Pal is 25 frames pr. sec. NTSC is 29.97 frames pr. sec.

The transition duration(right) is the number of frames the transition will take place between the current slide and the next. If this value is negative the slides will overlap. 

How do I make a DVD with menus?

Export as .gfd and load that file in Gui for dvdauthor(free) and you will have an almost ready to burn slideshow DVD disk with menus.

Media Player Classic complains over a missing codec?

Install Ffdshow(free) and make sure that avisynth is enabled under the video settings. If there is a problem with previewing try to install  Xvid or Divx. Or read up on the  Avisynth instalation FAQ.

Note: DVD slideshow GUI is a user interface for great free tools like Avisynth, Dvdauthor, HCenc, Media Player Classic, FFmpeg, Flvtool2, Mplex, Demux, mkisofs ect. and is coded in wxBasic. It comes as an installer with all the nessesary files included.
