Burned DVD is longer than movie file, Pro X6

[cdoughertycd]

I just noticed my burned DVD is about a minute longer than the rendered movie file. I rendered it to WMV, that file is 28:01 min long. The DVD when burned is 29:09 long. Does anyone know why this happens?

thanks,
Candy

What are you trying to create? A DVD that can be played on a DVD player or are you just archiving the video file?
Why are you rendering to wmv?

I am rendering to a DVD to play on a DVD player. I am rendering it to WMV because when I render it to MPEG4 then burn it to DVD for DVD player I get popping in audio. This is music and popping not good. I have read about this issue with burning for DVD player with MPEG4. I haven't tried burning to DVD for an MPEG4 for a while due to I was making too many coasters.

If I should be rendering the project to another kind of file other than WMV that won't have the popping in audio in the burn, great. I just went ahead and picked WMV only because it didn't make the audio issue.

The time difference not a big deal actually, I can put "run time" on the label to what the DVD plays, I was using what the rendered file length was before burning.

Just wondering why.

thanks

If you render to anything other than an mpeg-2 file for burning a standard DVD to play in a standard DVD player then VideoStudio will convert that file to mpeg-2 before burning the DVD - maybe the extra conversion is adding something to your video.

If you look at a standard DVD which you have burnt you will see .vob files - these are in fact just mpeg-2 files with the extension changed to fit the international DVD standard.

If in VideoStudio when choosing to 'Create Video File' you choose 'DVD' you do in fact get mpeg-2 as I would expect.

Brian, thanks for your answer, it helped.

Candy

what type of video files are you using as your originals, if you can provide the properties of the video files.

Trevor: I am using a Canon XA20 video camera with these properties on video I shot:
Frame width 1920
Frame height 1080
Date rate: 27559 kbps
Total bitrate: 27815 kbps
Frame rate: 59 frames/second

thanks,

Trevor, I'm looking at features of Pro X7 ultimate, going to buy, maybe that would solve the burn time difference issue.

Hi Candy

Its been a while since your last post.

VS X 7 has some quality issues when converting HD to SD.
I would advise that you continue to use X6

Please read this post
Sorry for the quick reply but in a little bit of a rush this morning, I will reply later....

Thanks Trevor:

I burned one project already with VS X7 ultimate. I'll see what it looks like. I rendered the file to MPEG-4 1080p, then burned that to a DVD and it looks ok with VS X7 ultimate. I'll keep track if I run into any snags with VS X7. There's one I'm encountering with VS X7 ult. about audio with overlay cross fades, will start another thread on that.

Hi Candy

Why are you converting the file/project to Mpeg4 , or is that a typo

A standard DVD uses Mpeg2 and its that format that is required, by using Mpeg4 you are rendering the files twice when once would do, or are your original video files Mpeg4?

With your project open in the timeline choose to Create Video File Same properties as your video files properties.
Same as First Clip will do that assuming the first clip is your clip and not a VS sample.

When that has finished insert it to a spare/empty overlay track to compare the duration with the project, you mentioned having a 1 minute difference.
Also check that audio / cross fade problem, if it still exists repeat the render but disable Smart Render, may help with the audio issue

Using the new Video file add that to a new project Share Create Video File DVD, that will create a Mpeg2 file suitable to burn a DVD.
If the duration is greater than 60 minutes you may have to reduce the Data Rate below 8000kbps.

Hi Trevor:
Apart from the video length issue, I've come up with another issue tonight in VS 7 ultimate. I rendered a 1.5 hr project to MPEG-2 but the quality is lacking, like you mentioned. Original files from the camera are HD. Quality won't work even if I could get it on one disk, it's 5.85 GB as MPEG-2 so too big for 4.77 disk. I'm thinking if I render it same as project settings the quality will be the same. I tried pulling the VS 7 project into VS 6 but it won't load, dang.

It took me two days to work on this project. It's a really boring project so I don't think I can stand doing the whole thing over in VS6. The only option would be to burn the whole thing broken up on to three disks as AVCHD to get decent quality but I have to make 20 sets, urg. As AVCHD total project is 11.97 GB thus need for three disks. The crossfade feature for overlays is almost worth the whole price of VS 7 for me, but now useless if I can't render projects from HD to MPEG-2 that look halfway decent. I love the crossfades you can do in VS7, something I was doing manually in VS 6. Grrrr Most of the projects I do run from half hour to more than one hour that I can usually get on one disk working in VS6 or lower. Maybe Corel is assuming fewer HD cameras are being used now or that people do short projects? I could try calling Corel or contacting them some way although they might know about this already.

Maybe when I get some sleep I'll feel better about this and will have enough energy to build it in VS6.

Thanks for reminder on why no need to render it to MPEG-4 for DVD burns, it wasn't a typo. I was thinking MPEG-4 would get me better quality. Standard DVD quality today is lacking. Most of the people who watch my stuff are older so blue ray is out at this point.

Sorry this is off the topic of my original movie file versus burn length.

Candy,
so where are you regarding the original problem?

[lata]

Hi Candy

Your project has been created using X7, you can save the project to open in X6.
It should open in full without problems.
With the project open in X7 go to File – Save As
Use the original name but add X6 to the beginning just to identify the new file.

Below the “File name:” is “Save as Type”, use the down arrow to select “Corel Video Studio X6 Project Files (*.VSP)”

After pressing Save close Video Studio X7

Open Video Studio X6, then File Open Project, search for the new X6 project.
Ok that should open the project in X6 just like X7.

Now, your project is 1.5 hours long, is that 1 hr 30minutes?
At 90 minutes long a data rate of approx 6000kbps should be used to render the project, it should create a file below 4.3 Gb, reducing your file from 5.8Gb

You need to create a template using 6000kbps
One option would be to edit the Project Properties

Go to Settings – Project Properties
From the first window choose Edit Format as Mpeg Files -- Then press Edit
From the following window choose Compression tab
Video Data Rate ---Variable 6000
Audio – Digital Dolby

All other settings should be ok—Press OK—three times I think.

Your project properties are set correctly.

Share Create Video File – Same as Project Properties
Should produce a file below 4.3 Gb and fit to disc.

Before you render the project you should fix that audio blip problem

Trevor, thanks so much. I'll try that. Also I'll see if VS6 held the overlay crossfades. Will keep you posted.
