    Mpeg-2?

    I export my timeline as a a mpeg-2 . I notice that when I try to upload it to youtube the audio file is separate so I get no audio. So I use studio 9 to make a dvd but don't burn and use the VOB file it makes which has the audio embedded in 1 file. Is there a way to make the VOB file with audio embedded with liquid 6.1?

    Thanks Mike

    Re: Mpeg-2?

    If you are on Liquid 6.1, you need to select to export a program stream and not an elementary stream. Program streams have embeded audio and elementary streams have seperate audio files. You should also not be making VOB files but mpg files to upload to online services such as YouTube.

    WOW I just tried to make a program stream. I never knew this stuff. What is a mpg file and how do you make it?

    Re: Mpeg-2?

    You choose. Mpeg1 or Mpeg 2. I suggest you read the manual. It has been years since I looked at how to set the output options in 6.1. 7.2 is entirely different in terms of dialog boxes.

    Re: Mpeg-2?

    Sorry about the dumb question I should be more specific. I look at the manual and theres not much on mpeg-1. Its seams to be the only way to make an mpeg-1 is a VIDEO CD with no other choice. I will be starting to do court depo work and they require mpeg-1. Which looks like crap but I see other peoples work and it looks better and it is mpeg-1. I guess there are different codecs to do this. Liquids did not not look good unless I am having a problem with my computer. I will try my computer at work tomorrow.

    Thanks Mike

    Re: Mpeg-2?

    You don't need to make a VCD to get MPEG-1.. Go to File->Export to File->MPEG-1. Choose the Custom preset and click on Modify Preset. Change the settings to 640x480 (which is correct for square pixels) and raise the peak and average bitrate up to 4M (4000 on the scale it uses). Leave the GOPs open as you get slightly better compression that way (close them if making a VCD). You can use CBR or VBR as you think is required. Check this for quality as compared to what you were getting before.

    Re: Mpeg-2?

    And if you need something better than this, then you'll have to use something outside of Liquid. I use CCE Basic (which is no longer available) and an encode to MPEG-1 @ 8M looks pretty good. TMPGenc should be able to encode to MPEG-1 as well.

    Re: Mpeg-2?

    Thanks Dave for the reply. I don't see all of these options. When I export to file I don't get an option for mpeg-1. I 1st get export to sequence or DVD. If I export to seq the only mpeg option I get is mpeg elementary stream or tiff, bitmap, quicktime, WMP ect. If I goto export dvd I get the option to customize. But no mpeg-1 I can choose under destination 9 choices and 2 of them is video cd & video cd+image which I assume is mpeg-1. But from there the only thing I can change is MB size and IPB settings. Under IPB settings Bitrate is fixed and there is no resolution option to change to 640x480. I can change GOP size and reference picture period. GOP is set to 15. Maybe these options are not in 6.1. I have 7.2 but have not loaded it yet. Waiting to finish what I have left and then reload windows and install 7.2.

    Thanks mike

    Re: Mpeg-2?

    That is because you are still on 6.1 and 7.2 has a significantly changed interface for exporting file types. Dave was referring to the export options in the current version.

    However, you can export a program stream (either mpeg1 or 2) from 6.1. There are options in that version to export as Program Stream 1 or Program Stream 2. I can't really help you beyond that as I have not had that version loaded for years and don't remember exactly how it worked. Check the PDF manual.
