    Hey,

    I’m working on documentary with 18 hours of footage and I’m using Avid MC 8.0.
    The problem is that the program runs very slow.

    Here are the specs:

    Raw footage files
    – AVCHD
    Computer
    – 2.3 GHz AMD Quad-Core A10-4600M APU
    – 8 GB DDR3 Ram
    – AMD Radeon HD 7660G/7670M Dual GPU (1 GB DDR3 dedicated)

    I’m working from an external hard drive connected through USB 3.0.
    All the file’s are AMA linked, not imported.
    I’ve done a sequence of selected Close ups.

    Questions
    – Would the program run faster if the files was imported instead of AMA linked?
    – Can I lower the preview quality and still keep the cut that I’ve made?
    – Any other long-term solutions that will speed up the program?

    Thanks,

    Adam

    [Ada Ya] “All the file’s are AMA linked, not imported.”

    That’s your problem RIGHT there…AVCHD AMA linked, and not transcoded. AVCHD is the most processor intensive codec out there…decoding it in real time takes TONS of resources. Avid isn’t built for that. Adobe is, but only if you add those resources…LOTS of RAM, and an expensive graphics card that enables the Mercury Engine.

    No, for Avid you need to transcode this footage to DNxHD after you link….and edit the DNxHD footage.

    [Ada Ya] “- Would the program run faster if the files was imported instead of AMA linked?”

    AMA link and transcode. IMPORTING is the old school way, and not as solid as AMA link and transcode.

    [Ada Ya] “- Can I lower the preview quality and still keep the cut that I’ve made?”

    Nope. It’s not the playback quality that’s the issue, it’s the codec. You can transcode the footage and relink your cut to that footage. In order to do that, you need to take the original AMA footage offline….

    [Ada Ya] “- Any other long-term solutions that will speed up the program?”

    Yup…use the workflow it’s designed for. AMA link direct editing really isn’t the way. It works best when cutting short form projects, and with formats that are easier to deal with, like DNxHD or ProRes QT files, MXF camera masters, etc. AVCHD is just a bear of a format. SO…AMA link and transcode…that’s the way Avid works best.

    Thank you for that very helpful post.

    Now I know that importing isn’t the way to go.
    And now I know that I need to take the current media offline, AMA relink
    and trans-code it.

    Is this the way to take media offline, AMA re-link and trans-code?

    That’s the OFFLINE/ONLINE workflow…you don’t necessarily need to do that. You only have 18 hours, not that much. Transcode to a full res codec, DNx145 or 175. Note, the file sizes will be about 4 times larger than the AVCHD…so you will need a decent sized drive. But 18 hours is not that much.

    Offline/online is for when you have hundreds of hours of footage. Or at least a few dozen.

    Transcode on import is the way to speed up your edit, but 18 hours of transcoded HD is going to use a lot of disk space. Space or speed: what do you need more?

    18 hours of DNxHD 145 is 1.2TB. DnxHD 175 is 1.4TB. Two and Three TB drives are available, and really not that expensive.

    no need to take AMA files offline anymore. Just transcode all your clips AND our current sequence to whatever flavor of DNX suits you. The continue editing off the transcoded sequence.

    So the things I need to do now is

    1. Get a 2TB harddrive
    2. Take current media offline
    3. Import new media
    4. Transcode the imported media
    5. Re-link my sequence to the new imported and transcoded media.

    Did I understand it correctly?
    I’m quite new to Avid and have never re-linked anything before.

    Thanks for all the help.

    [Ada Ya] “1. Get a 2TB harddrive”

    Yes.

    [Ada Ya] “2. Take current media offline”

    NO! You already have it AMA linked. NOW, Transcode that media to the new hard drive, DNxHD 145 or 115…depending on what options you have available.

    [Ada Ya] “3. Import new media
    4. Transcode the imported media”

    No…see above.

    [Ada Ya] “5. Re-link my sequence to the new imported and transcoded media.”

    Yes. Highlight the sequence and RELINK…should do it automatically.
