  • Edit to Tape: Writing Video.

    Posted by Shane Ross on April 2, 2009 at 6:32 am

    OK…I’m gonna post this over HERE as well. I posted this issue on the FCP board and never got an answer. And I really need an answer…this is taking up a LOT of time.

    DETAILS:

    MacPro 3.2 Ghz, 8GB RAM
    AJA Kona 3
    Footage stored on internal SATA drive
    ProRes 422…captured from HDV, but ProRes 422. 1080i 59.94
    22:45 TRT
    Outputting to HDCAM SR…1080i 59.94.

    Everything is fully rendered. FULLY. Yet, when I go to EDIT TO TAPE, ASSEMBLE EDIT…I get WRITING TO VIDEO for 18 min. Whyyyy? What is it writing?

    To solve this I thought I’d be clever and do what I did when I took my stuff (DVCPRO HD stuff) to a post house to be output. I exported a self contained QT movie, then brought it back in, and put it in a new sequence with all of my audio stems. Tried again.

    26-min write to video. WTF?

    What is going on? Never had this before. I get it when it is HDV, but ProRes? Even after I made a self contained QT movie with no text?

    AUDIO VIDEO settings, under AV Devices…the DIFFERENT OUTPUT to ETT box is unchecked.

    I don’t get it.

    I have also had this problem recently, but on a SD ProRes sequence, this was on a long running weekly show and was the first time this had happened. My theory (although untested due to time constrains) was that it had something to do with still .tiff files in the project which we normally don’t use. In the end the simplest and quickest workaround was to export a self contained quicktime and then ‘Edit to Tape’ this.

    I would be very interested if anyone has any other theories.

    Yes, there’s other theories.

    This happens when you have disabled clips in your timeline.

    This happens when it’s not fully rendered.

    This happens when there’s a mismatch between audio and video settings.

    In Shane’s case, though, this seems to be a bit of mystery.

    So, Shane. If I remember correctly, your problem is that even after you export and reimport, you are still getting this?

    Did you ever try increasing the default number of real time audio streams from 8 to 16 in your User Prefs? You said you have nine tracks of audio, right?

    I have no disabled clips in the timeline.
    The sequence is fully rendered.
    The timeline settings match the clip settings perfectly. All video is PRoRes and all audio is AIFF 16bit from the audio house.

    [Jeremy Garchow] “If I remember correctly, your problem is that even after you export and reimport, you are still getting this?”

    Correct. IN fact, it is WORSE. 17 to 22 min if I output the sequence, and 28 min if I export then reimport. That was the first thing I tried.

    I have 9 audio tracks, and I have switched from 8 channels to 12 channels of RT audio playback. I can try 16.

    [Shane Ross] “All video is PRoRes and all audio is AIFF 16bit from the audio house. “

    Is your timeline set to 16bit audio or 24?

    You exported then imported and married the imported video to your original audio, right…?

    It really looks to me like its audio related. Is it 48k or some weird sample rate? If its not 48k, or FCP thinks its not 48k, FCP might be trying to alter the video to keep sync.

    If all appears normal, you might want to try to put the audio tracks into Compressor and re-export as 16 bit/48k and see if it has any effect.

    But it says WRITING VIDEO…not audio. So this makes no sense to me.

    I have exported a self contained QT…video only, reimported that and put it into a timeline with the audio from the post house….same issue.

    I have exported a self contained QT file that INCLUDED all 9 tracks in the QT file…rimported…same issue.

    I’ll look at the audio details in a minute…the machine is occupied at the moment.

    You might also want to try a video only sequence…if the problem persists, its definitely something weird with the audio.

    [John Pale] “f the problem persists, its definitely something weird with the audio. “

    i meant to say, if the problem goes away, it points toward the audio.

    Definitely a strange problem to de-bug.

    NO audio! Good idea!

    Yeah, but the AJA presets have 24 bit audio and your audio is 16bit from the mix.

    I would imagine that this MIGHT have something to do with it. I know it doens’t make sense, dude, and I know you might not want to believe me, yet again.

    But take a look and see if it works.
