    Hi,

    I have a Cineform 4k video I want to play. I don't need to edit it or anything.

    I have downloaded the free codec from GoPro and installed the two relevant packages into my Quicktime folder. I have the Cineform preference pain in my System Preferences.

    When I go to play the video Quicktime starts a conversion process which takes a very long time because it is a large file. It ends up converting from a 330Gb AVI file to a 7.3Gb MOV. I assume I am losing a lot of quality in the processing because of the high compression. I just want to be able to play the file natively from the AVI file without this conversion for best quality, is this possible?

    Thanks.

    Thanks for the reply. No, I don't have QT7, I am running QT Player 10.4 bundled with Yosemite. Is that the problem and it will never work in my version of QT? Can I still legally download QT7? Would there be any problems having both versions installed?

    I noticed VLC won't play the file either. Failing any of that is there a decent free third party player which will work?

    Yes, that worked. Thank you.

    If anyone else is interested you can download Quicktime Player 7 from here:- http://support.apple.com/kb/DL923?viewlocale=en_US&locale=en_US

    Hi Mac Cineform Users,

    If you do a google search for "VLC cineform" you will find that there is now a freely downloadable CINEFORM decoder for VLC from "Kolor".

    I have tested this with 4K Timescape (4K Cineform wrapped in AVI) video playing back via USB 3 connected HD (USB 3 via Sonnet Allegro Pro PCIe Card to MacPro) and it appears to decode ok, but I had some dropped frames.

    I think this is due to speed of USB HD, but will also test via RAID or 10GBE connected storage.

    This is good news for Mac users looking to play 4K video, as my experience with the 32-Bit QT 7 Decoder is that it is very poor performance.

    Cheers,


    Zebity.
