Rendered DVD To Bright!

[Nick White]

OK.
– You make an AVI in Vegas, then take that same video into DVDA to make DVD files? We have to be sure that the good avi is the source you use for the bad DVD
– What happens if you Prepare in DVDA, and choose to save it to HDD, then play that VIDEOts.vob on your computer?
– are you using the same programme to play the DVD as you do to play the avi? If so, what…well if not what are you using for each? 🙂

BTW.Sorry for all the questions. There are so many variables and reasons for failure (and only one way to get it right 🙁 )

ummm…when you say your friend is going to post what he did…where? It would help more if you made sure that he posted here as a reply, so that people following your problem (me for a start) are ensured of seeing the extra info without having to hunt for it.

If you want your problem solved, please try to address what people say to you and make sure that your evidence and information is orderly. I know it’s a PITA, but it’s the only way. Sorting this stuff is a logical process…at best….(sometimes it feel like witchcraft) and we all need to be very pedantic about it to get results.

OK, so the problem you are describing is not brightness? It is time for you to be more specific about what you are doing and seeing. What formats are you using to render the video for use by DVDA? What bit rates are you using for the render? What does the rendered video file (and I do NOT mean the AVI file) look like? Is it “crisp and clean”? It would also be helpful if you could describe what you mean by “crisp and clean”.

The resolution that’s on the DVD isn’t as good as the AVI. In the mpeg2 codec, the video is washed out in some bright spots on the DVD but not on the Windows AVI file. Hope this helps. I wish I could get as good of an image on as the AVI file brings me! Is this possible?

[Nick White]

Grab a little app called MediaInfo. It’s free (although I have donated).

Install it and use it on both the avi that looks good and the DVD file that looks bad. If you install it OK, you should just be able to right click on the file and the MediaInfo option will be in the context menu.

In each case, ask to View/Text from the MediaInfo menu. Select all, copy, then past into a message here. That way we can at least get an idea of what sorts of parameters were used for the files: bitrates etc. You don’t have to know all the settings that were used.

It’s a good start.

Hi Bob,

The DVD I burned looks like the quality of a VHS tape with highlights that don’t exist in the original AVI. I just posted some specs from MediaInfo that I was told to download. Please look at those and hopefully it will give you some more clues! Thanks for your interest in my problem Bob. I really appreciate your willingness to aid my quest in better video production

Well I have not _helped_ much yet, but yes I am interested. 🙂

However. This is the data for the actual DVD file, from what I see and unders5tand. Right?

Now _that_ would not have been rendered by Main Concepts in Vegas. Main Concepts would have been used to render the file out of Vegas, which is then taken into DVDA and prepared for burning. THAT file needs looking at, to see if it is the same as the DVD. The Main concepts does an MPG file.

I cross posts as I type. You are saying to Bob that the DVD is not as good as the original AVI. Was the avi one you created in Vegas, or the actual source AVI right from the start?

Nick

[Nick White]

Just a note. The data for the DVD looks pretty good for a DVD. It has a solid 9500KB/s max rate and a good average of nearly 7000KB/s. But that is no indicator of the DVDA input file’s quality.

[Nick White]

Rats! I meant to say that you need the Mediainfo of the actual file that Vegas put out to feed to the DVDA.
