    I have some MPEG video files (MPEG1 actually) where the actual contents are anamorphically squeezed (i.e. full frame 16x9) but the meta-tags indicate the files are 4x3.

    Question: Is it possible to alter the meta tags to 16x9, without re-rendering (and hence further degrading) the entire file?

    I believe you can, but I have not done it myself.

    You might like to look at a java application called ProjectX - which I know does have an option to change aspect ratio. ProjectX will allow you to fix/change features of the MPEG file while demultiplexing to audio and video stream files (you would then have to use another tool to remultiplex the streams back to a single MPEG file).

    You can find information on ProjectX and a whole bunch of other useful tools at www.doom9.org.

    Goto http://www.wincesoft.de/index.html

    On the right there is a menu tree - click on DVDPatcher.

    I have used this tool to patch MPEG2 file headers to change aspect info.

    Maybe it can do MPEG1 as well.

    Excellent! DVDPatcher has done the job. Thanks, groovyclam. Thanks to the others, too. Restream says it won't work on multiplexed files which is why I tried DVDPatcher.

    A bit late I know ( :oops: ), but probably worth a mention.

    There is something I have used for MPEG2 files. It's called AVestensione and can be obtained from www.offeryn.de (home of PVAstrumento). The beauty of it is that it comes with a registry tweak that adds an option to the right mouse button click in Windows explorer.
