Length of time to Burn a DVD?

Post by silver_angel »

Hi,

I just completed burning my DVD but it took over 3 days to complete. Is that a normal length of time for it to complete the whole project? I believe it was the converting of the video file that took the three days while the burning was quick. Is the problem the video because the file size is large or is the program slow?

Thanks

:shock: That's a long time... (I think most people would give-up before waiting that long!)

It has something to do with your source format. Note that "AVI" is a "container" or wrapper format, and it can contain any type of compression. (You might have an AVI/DivX or AVI/Xvid file.)

You didn't say where the file came from, but if possible you should use a different format in the future.

If you are stuck with this format, you can try using a 3rd-party program such as SUPER (FREE!!!) to convert your files to DVD compatible MPEG-2 before importing the video into Movie Factory. (i.e. you can use the Movie Factory Project Properties, except SUPER can't encode to Dolby audio.)

I've seen reports of highly compressed formats like DivX or Xvid (or other formats) taking 8-12 hours to convert. Your bitrate of 3560kbps is not that compressed... but it still could be one of the difficult formats. (i.e. High definition DivX could have a bitrate in that range.)

If the resolution and framerate have to be changed (to meet the DVD specs) this will add to conversion time also.

You haven't answered the important parts of the first question
Properties of your source files (format, file size, where did you get it?)

The term "avi" refers to a type or class of video and can contain many different variants. I strongly suspect that your video came off the internet and is in a highly compressed format such as DivX Xvid or MPEG4.

Generally speaking uncompressed "avi" eats 65 GB of hard drive space per hour and so you can imagine that it is not practical for the home user to use and manipulate this form of video. For this reason the boffins devised various methods of compressing video to make it smaller and so more practical.
When video is COmpressed it must later be DECompressed to view it. Thus the term CODEC.

The most widely used CODEC for video EDITING is a format developed by Microsoft and termed DV which stands for Digital Video. DV eats about 13 GB of hard drive space per hour and is easily edited by various programs such as MovieFactory, MediaStudio, VideoStudio and other competitor products.

If your aim is to create a Video DVD disc (One of those you get at the Video Shop to play in your DVD Player) then the video has to be converted into MPEG2 (This is another CODEC) which fits about 1 hours worth of video onto a standard single layer 4.3 GB DVD disc in Top Quality. Just like old fashioned VHS tape players you can reduce the quality and fit more on the disc, perhaps 2 or even 3 hours. Think of it as long play or extended long play.

Some Video CODEC's were designed for distribution over the internet, those I mentioned DivX, Xvid and MPEG4 eat about 700 MB per hour though they retain very high quality. Every silver lining has its cloud and in the case of these particular formats they are difficult and at times almost impossible to work with. As you have experienced they can take extremely long times to convert to MPEG2 so that they can be used on a Video DVD disc.

All is not bleak... the long conversion times only apply to Video editing/authoring programs that were designed to deal with more traditional CODEC's (MovieFactory, MediaStudio, VideoStudio etc.)
If you search Google or your favourite search engine you will find dozens of programs available that will convert those highly compressed formats into something else - in your case you would want to convert to MPEG2.
Those programs normally convert a 1 hour video in about the same amount of time. You can then use that converted program with MovieFactory.
