Cannot Open AVI files in Express 4

I download the video from my camera, panasonic dvcpro hd p2, as an AVI file but get an error when I try to import it into HitFilm Express 4. I've purchased the Premium formats add-on, but it did not resolve the issue.

Here's the error:

INVALID MEDIA - The media could not be imported.

Here are the File Specs:

Frame width: 720
Frame height: 480
Data rate: 28834kbps
Total bitrate: 29858kbps

    Link to the AVI file and I will try importing into my Express 4?

    Give us a MediaInfo report of the AVI file. MediaInfo is a free utility.

    Did these files come straight from the camera or through some conversion/extraction software.

    I am guessing that the AVI file is using a codec that Video for Windows (aka AVI)  does not support without a Video for Windows codec installed.

    If the source video is AVC, you typically do not want AVC in AVI files. If it is an All-I frame type file this can be okay but you still have to install a VfW AVC codec.

    @NormanPCN it should be noted that other NLE's required specific, third party add-ons to read Panny's P2 codecs (Raylight used to be a $150 codec). Panasonic has something going on in there to make it "proprietary," although I've never dug deep enough to find out what it was. 

    28mbps for SD video? That's very likely an all-I frame codec.

    A Mediainfo report would be really helpful because there are DVCPro VfW codecs out there but it would help to make sure that's what you have in the AVI file first. 

    Handbrake should be able to import the native MXF files and you could transcode to Norman AVC but you'll lose 4:2:2 subsampling  dropping to 4:2:0 in the process. If you're planning on chroma key work this could be a bad thing. VirtualDub FilterMod can also import your native MXF files and you could transcode to Cineform keeping the 4:2:2 subsampling. Both of these options are covered in this thread:
