  • Sound out fo sync when exporting with final cut.

    Posted by Andrew Johnston on February 19, 2009 at 9:57 pm

    Hey everyone,

    Having a problem with Final Cut that I hope has an easy solution.

    I have a project that is about 60 minutes long. I’m ready to export. I’ve exported once already and after awhile of playing it the sound all falls out of sync. Does anyone know why this might be happening?

    I’m exporting using best quality and compressing with H.264.

    Footage is HD 1080

    thanks

    -Drew

    [Andrew Johnston] “I’m exporting using best quality and compressing with H.264. “

    Exporting how? Using Quicktime Conversion?

    The following will always work properly:

    1. First, do the following: Sequence>>Render Only>>Mixdown

    2. Export a Quicktime Movie using current settings.

    3. Import that QT into Compressor and export your h.264.

    Isn’t that compressing it twice though?

    here are the settings i’m currently using:

    Using Quicktime Conversion…

    Compressor: h.264
    Quality: best
    Keyframe every 24
    encoding: best quality
    Dimensions: current

    Sound

    Linear PCM
    channel: stereo
    Rate: 48khz
    Render quality: normal
    Sample size 16 bits

    let me know if i forgot anything.

    No, that’s a common fallacy — exporting using current settings does not add a recompression pass (unless of course you check the box that forces it to recompress all frames).

    Get out of the habit of using QT Conversion, it’s inferior to Compressor.

    No, not when you export at the sequence settings as a self contained. FCP ingests/works with QT files natively, so there’s no compression going on. (Well, unless you have a weird codec as your Compressor setting in your sequence setup, but that’s another story.)

    If you do the self contained (which, fair warning, may very well be HUGE), the chances of it falling out of sync are less, but YMMV.

    What exactly are you using the h.264 for? If it’s for viewing on the web, browsers are going to choke at those settings, and Compressor offers more options for compression at least.

    Okay thanks David I’ll try what you suggested, i’ll post back if it doesn’t work out

    And Nicole, this isn’t for the web this is going to be my master. I pan on exporting 2 masters, one meant for a dvd and one meant just as a computer file to present to my cient.

    Well hoorah it’s not going to the web, but… I would never export an h.264 as my master file. I always do a self contained quicktime and so does everyone I work with. You always want the highest quality contained file you can get as your master, and h.264, while nice, does not cut the cheese. If you think you might end up doing alot of h.264 compressions for preview purposes, you might want to consider an Elgato Turbo, which is a USB dongle and speeds up h.264 compression (I can get a 4:1 ratio sometimes). Just use that self-contained file to make all subsequent work- the h.264, the dvd files, and most importantly, whatever else the client will ask for in 6 months. Clients are like tornadoes- they strike without warning, at any time, and can wreak havok on your work. The self-contained can help manage the damage 😉
