  • Error importing MP4 into After Effects CS3

    Posted by Mitchell Stevens on April 18, 2009 at 3:03 am

    I’m not sure why, but whenever I try importing an MP4 file into After Effects CS3 an error dialog shows reading “After Effects error: File “video” cannot be imported – files of type “.mp4” are not supported.

    I’m not sure why MP4 is not supported due to mp4 being a well known format… Also, when I try to import a video no MPEG formats are on the list of acceptable formats?

    Any help will be appreciated
    Thanks

    As they’re professional quality software, Adobe products tend to ignore the Mpeg importing format as, well mpegs are mostly useless for editing.

    This has less to do with Adobe and more to do with the fact that Mpeg is a lossless format.
    You can Google for the exact specifics, but how I understand it is – mpeg works by making a key frame every x number of frames – which is a full frame image. The inbetween frames however just contain the differences and are layered on the previous keyframe, so it all doesn’t duplicate data. Fine for watching, but useless for editing – generally they expect you to use something better.

    That said for small web things, or quick stuff it would be nice if it worked better. I’ve used MP4’s before so it is possible(*), just don’t expect gold.

    *I thought I’d just imported mine straight in to be honest – try converting the file with something (Media coder or Super are probably what I used) or maybe checking if you have the correct codec.

    Ok, thanks very much Paul. Also, another question, MP3’s are also an unnacceptable audio format to be imported into After Effects… Is that my fault or just the program?

    Hmm.. that’s odd to be honest. MP3’s are also not the height of professional quality, but I’ve definitely used them in my productions and never had any problems importing them myself.

    Does it refuse to import them or just refuse to play them? Because if it’s the latter, be aware AE only plays sound through RAM previews – so it can seem the file won’t play even when it will.

    Sorry for the extra post but the message I recieve when importing an MP3 or M4A file is “After Effects: AEGP Plugin AAF: Error occured while creating project. (5027 :: 12)”

    It refuses to import the mp3 file – it’s impossible for me to import one, i’ve tried

    I also can’t import mp3 to AE CS5! I checked and updated the software still doesn’t work. I also converted the file into an .aif file AND still it won’t import! what the heck?
