Thread: Codecs and MP4 video...

  1. #1

    Default Codecs and MP4 video...

    First, I have a piece of gear that generates an MPEG4 file, this file is a container for MPEG 4 video and MPEG1 level 2 audio. I am trying to use AVS Video converter to make this file (which saves as a "title.mp4" a WMV so I can edit these videos in Windows Movie Maker. Here is one thing I was told:

    It appears that the AVS video converter codec does not support the MPEG1
    level 2 audio portion of our MPEG4 container. You are headed down the
    correct path trying to edit the movie files with Windows Movie Maker (I doní
    t believe that VLC has the editing capability that you need). I think if
    you first delete the current AVS MP4 codec and then re-install a new MP4
    codec with support for the MPEG 1 Level 2 audio everything will work as expected.

    I can convert these videos but when I do, i receive no audio so that is where I am stuck. I don't know much about formats and I got the information above from the product manufacturer, but they said they were not sure of how to do what I am asking.
    Any thoughts from anyone? Or other software to make these movies? Thanks.

    I have been using MPEG StreamClip 1.2 Squared 5 - MPEG Streamclip video converter for Mac and Windows recently and got good results from it. It has very basic editing, you can just do trimming but it seems to be very good when it comes to converting files from one format to another. I also downloaded QuicktimeAlt181 (freeware) which you need to install first as it has codecs that MPEG StreamClip 1.2 needs to run properly. You then run MPEG StreamClip 1.2 and then click on either File->Open Files and locate your mpeg4 file.

    After you have the file in the program you can then go to File and select either Export to Quicktime, DV, AVI, MPEG4 or other Formats - I wouldn't use wmv. I tend to stick to avi and mpeg4, the avi uses Apple DV encoder and works well with Adobe Prem Pro and once you get it in there you can work away with it as much as you like. If I want to put something on Youtube straight away then I select MPEG4.

    The setting you can try are...

    FILE->Export to AVI

    Compression - Apple DV PAL

    Quality - 100% drag the slider to the right.

    Limit data rate to - 3600kbps - Tick the box to activate this.

    Sound - MPEG Layer 2, see if this works, if it does then use this all the time, or try MPEG Layer 3 next time.
    Stereo, Auto, 256kbps.

    Frame Rate - 25fps.

    Frame Size - Choose one of the settings or use the Custom Setting at the bottom.

    De-Interlace Video - Ticked.

    Field Dominance - Lower.

    Click on MAKE AVI button.

    The avi will take a while to render, and when done you should be able to open it up in a 'real' editor, work on it and then Export to DVD.
