re-encoding compliant video

DiscCoasterPro · Post by **DiscCoasterPro** » Fri Sep 30, 2005 1:35 am

Hello. I just learned something about DVD Workshop that I have been laboring over and thinking I was doing something wrong.

When working with compliant video files, it is my understanding now that DVD Workshop's encoder with re-encode all files no matter what. Can anyone tell me if there is a way around this, or if I can add additional encoder drivers to the choice list in DVD Workshop's Disc Template?

I didn't think that any higher end authoring program would come without an option to either encode or bypass compliant video.

thanks for your help,

afaik, if you trimmed compliant mpeg files in WorkShop, it will reencode it but only those edited parts.

check the options panel if the "convert to disc template" is check for both audio and video. if the check box is greyed out, it means the file is not compliant and has to be converted.

Thanks for your reply. Let me ask this. I originally assumed that Workshop was re-encoding my compliant files based on the time it took to complete a project on my computer. When I inquireed on a video forum, the gentleman there informed me of this in workshop.

I have a p4 2.8HT with a Gig of dual channel pc3200 mem. A 4gig composition with menus and chapters can take 2 hrs to complete from the time I click on burn.

My question is, does this time frame seem about right for other users?

thank you,

2 hours seems too long if it wasn't re-encoding.

Do you have alot of motion menus

As ploggy asked, do you get the option to "Convert to disc template" in the EDIT step (under the Video and Audio tabs)

What are the properties of your source videos

What are the properties of the disc you are creating? NTSC, PAL, etc...

thanks for the reply. No motion menus, nothing really crazy, a couple of submenus and a dozen chapters all together, thats it.

I deleted the project files and the source captures already but I will take specific notes on the mpeg properties of future captures. I do believe that if I looked correctly when I was trying to figure this out, all the settings fell within the template

Here are the helpful posts by the folks over at the other forum

thanks for looking. Taelon has really help me understand quite a bit up to this point both from his replies to my posts and his posts in general. His is the post that pointed out DVD Workshop's preference to re encode.

thanks,

I read the link you provided, and unfortunately those folks do not understand how DVD Workshop 2.x works.

If you have compliant files for a DVD, then DVD WS 2.x's default is to NOT convert them again.

In the EDIT step, there are tabs for Video and Audio. Under those tabs is an option to "Convert to disc Template" -- if that option is open and user-selectable, then your source videos are compliant for the disc you are trying to create -- therefore, no re-encoding is needed (DVD Build process should go by very quickly). If that option is ghosted, then DVD WS does not believe your source videos are compliant, and will convert to the settings in your project template (taking a while to convert)

Regards,

Forgive my ignorance, let me just be sure on this. If the option is available to be checked ... BUT IT IS NOT CHECKED .. then DVD Workshop will not re-encode files that are deemed compliant by falling into compliant parameters.

If however the option is available and IT IS checked, then DVD Workshop will convert files that .. .although compliant, do not actually "exact" the specific settings.

Is that accurate?

**edit** one last question (hehe for now)

Will that checkbox change in the edit mode for each title that is currently highlighted if some titles are compliant and some are not?

sorry George ..I'm trying

Okay then ..I do believe that I misunderstood that checkbox on my last few compilations. It was indeed available, and I did have it checked.

Say, I just understood three things in a row up there ... perhaps there is some hope for this old timer after all.

Thank you!

I'm also having problems with 'compliance'.

I am importing MPEG2 files created in ProCoder Express (for Edius), and would expect them to be compliant. However, the DWS 'convert to disc template' option is greyed out so I assume DWS does not seem the files as compliant. It then converts them before burning the disc, but I end up with poor image quality.
Perhaps I'm getting something wrong in ProCoder, but I've tried its preset templates and also custom setups and the settings seem to make sense.
Any suggestions very much appreciated.

I don't know ProCoder, but are you sure you are creating mpg files that are DVD compliant in the same format as your WS2 project settings? This is important.

Thanks for the reply. Possibly the case that some settings are different - though I can't immediately think where. I'll go back and have another look.
Out of circulation for a week now so if I don't post that's why, but if I do eventually find this to be the issue I will post again in the hope that others might benefit from my learning curve!
