Why does "Converting audio of the title" take so l

I'm working on a slideshow DVD. When I go to render to an ISO file, it takes over 25 minutes for MF5 to get thru the "Converting audio of the title" step, on a 3.4 G dual core PC. What audio is it converting??? None of the slideshows have background audio, and I selected "No audio" for the title.

Hi WB, welcome to the forums,

What it may be converting is the audio of your Video, which is also known as the Main title in DVD authoring. Could you post the properties for the video files, especially the audio?

If DVDMF thinks that it is not DVD compliant, it will render it, even if you have checked the Do not convert box.

Videoman, thanks for the reply.

In this case there is *no* video! The content is entirely still images, mostly bitmaps, slideshows, nothing else. There are NO video files in the project.

Ok I understand what you are saying, however what is the properties of the file that you are inserting into DVDMF to create a disc? They have to be MPEG-2, which is a video file.

Just thought of something, you are using DVDMF to create the slideshow, so DVDMF has to create the MPEG2 video file, before burning to disc. Unless you are burning a Data DVD, the files must conform to DVD specs, and part of that is the files must be MPEG-2.

What is troubling is that you say you did not add any audio to the slideshow. DVDMF does by default if you use a template to create a slideshow, add background music.

"they have to be MPEG-2" ??? Have you used MF5 to create a slideshow?

I appreciate the effort to help, but please read what I wrote. The only files being inserted are bitmaps and jpegs. These are image files, NOT video files!

I have selected "No audio" on all of the slideshows AND on the TItle (menu) section. There was a default audio track for the Title, and I turned it off.

It is possible that it takes MF5 this long to render the image files as video, but if that is what it is doing, the message displayed is incorrect.

At the end of the 25 minutes what happens next?
It may be that MovieFactory is in fact doing something but has not updated the video display.

Some of these on screen messages are simply 'comfort factors' displayed to let the user know something is happening - a bit like when you install XP and you get all sorts of adverts popping up
"With XP you can do this"
"With XP you can do that"
and so on.

What Ron is trying to tell you is that despite the fact you are creating a slideshow from still images, what happens under the bonnet is that the software creates a video from those still images. That video will be in MPEG2 format and later will become your VOB files on your DVD disc.

Dependant upon how many pictures are in your slideshow plus the complexity of your DVD menu it could take even longer than the 25 minutes you have mentioned.

I appreciate the efforts. Despite the post count, I'm not a newbie. I wrote my first computer program in 1964, in 360 assembler. Been around a while...

So, it's a programming error. The message says "Converting audio of the Title" but it's actually working on something else. It's rather slow at generating video from still images, but that's another topic...

I believe it is actually working on your audio to be a compliant DVD -- it just happens to be a "silent" audio track.

Can you guys read?

All kinds of suggestions about bloating dvd's, extra chapters that aren't there, mpeg files I "must" be inserting, and all manner of other things that have nothing to do with what I asked.

And amongst the noise a couple of thoughtful, concise posts that actually make sense.

I suppose it could take this program 25 minutes to render a silent audio track for a 25 minute slide show, but that sure seems excessive to me - it must be doing it in real time!

Oh, and my eyesight is excellent, thank you - I can still see detail on Jupiter or the Sun in h-alpha that no one else notices...

Well, this is user-to-user forum. None of us know what the program is doing internally... All we can do is guess.

And, we don't know anything about the playing time, or the file size for your DVD (Of course, the resulting MPEG-2 file will be bigger than sum of the stills.) If you are filling-up a DVD, and if the "silent audio" hypotheses is correct, you have to read almost 5GB, multiplex-in the silent audio, and write-back the ~5GB multiplexed file.

25 minutes does seem like long time to me too. But, I've never tried making a silent DVD.

Can you guys read?

Yeah, but some of us need bigger print.
