compression of video and VOB vs. AVI

[thoefen]

Hell all,

I have been having lots of issues trying to make a DVD-R that will play in my fathers Toshiba DVD player. After some suggestions from people on this site I decided to buy Sony Vegas Movie Studio. I was thinking that my problem might be that MyDVD stinks and it could be an authoring problem. Anyway, I have the software and now have a very newbie question. I made my movie using the video from my camcorder and added music to it. The music I used was in MP3 format. Could this be causing part of my problems? Or does this just add another rendering step? When I made the video using Vegas Movie Studio the AVI file was ~4.6 GB. When I read the file into Architect it ends up compressing it into a 1.6 GB file. I converts it into a VOB file. Can I turn off the compression? Do most people compress their video and write it as a VOB file? Could the compression be my problem? Any insight would be helpfull.

Thanks,

Todd

Have you tried burning to different media. Compression is not required unless the dvd exceeds 4.37GB.

I dont understand why the final dvd output would be only 1.6GB, there should be no compression to this level.

How are you trying to burn the dvd. Are you actually burning as a dvd video compilation?

I have tried a lot of different things. The original file is close to 4.6 GB so I am above 4.3 GB foe sure. Is that why it is compressing it? Is that my problem with the other DVD players not being able to read the files? At first I thought it was the media as well. I had some Phillips DVD-R's at first and ended up buying some Taiyo Yuden DVD-R's. That helped my situation a little. Here is a previous post https://www.videohelp.com/forum/viewtopic.php?t=270623&highlight= explaining what I did. The DVD-R's I have been writting have worked in my old Panasonic and Toshiba DVD players but when I sent my Dad and brother the DVD neither of them could read it in their brand new Toshiba players (Toshiba SD-5970 or SD-5960??). My brother has a really old cheap DVD player and it played just fine in that. It is only the new players that it doesn't work in. I looked up my father's DVD player and it says that it reads DVD-R's. That is what is driving me crazy about this.

To make the DVD I have been creating the AVI file in Vegas Movie Studio. Then I open DVD Architect Studio and click on the Make DVD button. I am not sitting in front of my computer so I am trying to remember everything. The screen lists the video and audio portions and says something about compressing them. If I try to optimize the setting I still can't create a non-compressed version. Then it renders the files and makes these VOB files. I am guessing that all of the chapter info and so on is included in these files. Do most people burn AVI files or these VOB files. It didn't really give me a choice. I am assuming that the AVI file is just one file that has everything and then when I use the authoring software it breaks up the AVI file into more manageable VOB files with chapter info and so on? I know Vegas is picky about compatible formats. Is MP3 considered a compatible format? Could a non-compressed video solve my problem?

Compressing a 4.6G AVI into a 1.6G MPG2 is normal, and in fact, a mandatory step. Vobs are also mandatory for DVD, these are created during "authoring".

Note that the AVI itself could be "compressed" in a number of different ways, rendering the above filesize comparison essentially useless without mention of AVI codec used.

MP3 is NOT valid for DVD.

Check the What Is stats to the left.

Many Toshiba players are extremely picky about compatibility.

I find that MyDVD, while not allowing for much menu creativity, is VERY good at producing compatible DVDs which play on my Apex, Playstation, and my brothers Toshiba.

I don't use the software you are using so I don't know the details of your process. Making VOB files is mandatory since it is the DVD standard. A few DVD players will play AVI files but most will not.

Don't try to just copy the files to the DVD. The DVD must has a specific collection of files in the proper directory. Use your authoring software to create the DVD and write the files to the DVD so it includes all the necesssary files.

The mp3 file for audio is ok since your encoding software should convert it to the proper format.

So I am trying some different ways of writing the files. The first thing I did was write an AVI file out of Vegas and then opened it in Architect. When I went to "prepare" the video it doesn't really like the AVI. It gives me warnings about how it will need to compress the video and audio. Then I told Vegas to Burn a DVD from Vegas. It in turn wrote an MPG for the video and a WAV file for the audio and then sent it to the Architect program. Which way is the "correct" way to import the data into the authoring program. As a AVI or the MPG/WAV combo? I used only WAV files in the Vegas prgram as well.
