long burning time

[ottersea]

I have a video clip that is 3 hours long and have been having a problem burning it to DVD. I have a project that was 4 clips combined into one. I go to share/create disc/dvd. Then in the burn window I add the video clip and click on burn. I have been using a DVD-DL discs. The problem is it is taking forever to burn the disc. The one time it did go through it had a unrecognizable error so was no good. The other times it has been going to like 12 hours and is only 25% done. What could be causing it to take this long to burn? This is the same process I have been using and it has always worked usually taking a little longer to burn then the length of the clip. Any ideas?

What is the format of the video in your project? Have you first converted it to DVD-compatible mpeg-2?

And what are the burning properties being used? Have you adjusted the default bitrate (downwards presumably)?

[ottersea]

I have captured the clip as MPG and also have made a single clip out of the 4 individual clips as MPG. Where do I lower the bitrate? In the burn window projects setting it shows bits as 24 and audio bitrate as 256kps. In the change MPG setting it shows 6 choices from best to good. I am not sure what my setting is other than defalut. Is there where I change the settings? If so what would be the default setting so I know where to start. Thanks for the info.

To burn 3 hours of video to a dual layer disc, the bitrate would need to be around 6000 kbps. So when you combine those four clips into one new video, you need to go to Share > Create Video Clip > Custom. Choose mpeg-2 as the output format and click on the Options button then the Compression tab. You change the default bitrate of 8000 kbps down to 6000 kbps.

Okay I will try that. It is my understanding that I need to first create a video file before I burn it to DVD. Is that correct? I have been just burning the file from the clip that is captured without creating a new clip first. Should I always create a new video file? I have been capturing as MPG so that I did not have to convert from AVI to MPG.

Hi

A standard DVD has to use Mpeg2 type video file when burning the disc.

I always convert my projects to Mpeg2, then use that file to burn a DVD.

You say you have 4 video files, if you convert each you will have four Mpeg2 files.

Start a new project, Share Create Disc, this opens the burner module, nothing in the timeline
Add Video Files, icon top left, Add your Mpeg2 files.
For each video you add a link will be placed on the Main/Title menu.

If you need to combine all 4 to one file then that’s ok

You say you have captured to Mpeg rather than Avi.
Can you tell us what you are using to capture the video, is it a camcorder, is the camcorder a MiniDV type?

Finally from the timeline please right click an original Mpeg file, select properties, what are they.

This will help us to recommend the Mpeg2 render settings.

My quick guide may help explaining the process

Hi ottersea

Basically your video file is to big in Gb’s

To burn a standard DVD the disc requires a compliant Mpeg2 file, you can add such a file or the program will convert the project to create one, this process will take some time.

If you add a compliant file then there will be no conversion reducing the burner process times. Your video file does look compliant with the exception of its size at 13 gb is to large to fit a dual layer disc, and that is due to the Data Rate of 9000kbps and the audio using LPMC. and of course its duration.

Ken suggested a data rate of 6000kbps but I think lower at 5500kbps, and Digital Dolby audio.
Downscalling the file, rendering to the new settings will take a long time as you have found.

You can do this yourself via the edit timeline, once you have a file under 8 Gb
Then the burner process will be much quicker.

Okay thanks. Will try to do that.
