VS 11.5 Long Burn Times

I apologize if this question has been posted previously.

After editing, when I start the burn, the process takes a very long time. For the current project, the time is now 21 hours and shows Total progress: Convert menu 44%, Detailed progress: Building motion background of the menu page [003/004] 18%.

The source files are .mts 1920x1080. Project is 1 h 27 m. I selected the two pass, based on posts in this Forum. Clicked Yes to fit 5.3 GB to disk, which then shows 4.30 (4.62 GB) on the size bar. Used thumbnail menu. There are 10 Chapters selected. Burn to DVD as DVD with additional Create Folder selected.

The first project I did, had similar settings, but the total duration was at 1 h, and 3.8 GB so there was no additional compression required to fit to disk. That project took 10 - 3/4 h to burn.

Processor is Intel Core 2 Duo Extreme, 4 GB RAM, 80 GB HDD free, virtual memory page size set to 4 GB.

1. Is the Total progress percentage based on tasks or estimated time to burn?

2. What are typical burn times when the fit disk is used for a 1-1/2 h movie using mts source files?

3. Are there settings that I need to change to recommended values to reduce the burn time?

What sort of disc are you burning?
A standard def dvd video disc?
If so it has to convert all your files to dvd compliant ones, which can take some time.

Yes, I am burning to the DVD-video format on a 4.7 GB DVD disk.

Editing was done by bringing the mts files into the Library and then adding to the timeline. There are approximately 150 clips, total edited time is 1 h 27 m, all in one movie.

I'm not a VS expert, but as each frame has got to be changed from 1920x1080 to 720x480, to mpeg2, possibly it may be interlacing it, compressing it to fit the disc, then to make the vobs etc, I don't think you'll reduce your rendering time in the app.

If down converting the footage with the camera is an option, so you capture sd rather than your hd, will considerably reduce your working time.

You say in your first post that after editing, you burn. Well, I would suggest that after editing high def video in particular, you think about down-converting to standard definition (Share > Create Video File > DVD) instead of jumping straight to Share > Create Disc > DVD. In fact, if you know from the start that you intend to create a standard definition DVD, and your source is a high def camera, you should think about downloading from the camera in standard definition format and editing in that.

Anyway, you finish your editing, and then produce a standard definition mpeg-2 of the whole project. Then you open a new project -- don't bother about a name for it. The objective is just to empty the timeline. Then you choose Share > Create Disc > DVD, and insert your new mpeg-2 in the burning timeline. Click on the middle of the three icons in the bottom left of screen, and make sure 'Do not convert compliant mpeg files' is ticked. then build your menus and burn.

All that being said, with your computer, that is still an impossibly long time for rendering to take place in the burning module, even with 'reduce to fit' activated. That function, by the way, is not particularly good. It is far better to calculate from the start how long your project is, and then know that for one that is approx 1.5 hours long, as yours is, that for a single layer DVD, you will need to use a bitrate of around 6000 kbps or slightly higher, and it will fit without 'reduce to fit' entering the picture.

Second, in the burning module, when you build your menu, you will see that there is an animation of the menu, both menu in and menu out. Menu in, if I recall correctly, is not active by default. However, menu out is active, and I have found that it adds hours to my renders, and even on occasion causes the whole thing to collapse. So I just disable it. Sorry I can't be more specific but I am away from home and don't have VS on this computer to be able to describe exactly what I am talking about.

Thank you to both of you. I will try the MPEG-2 conversion and see how that works.
