    Newbie Post Audio stutter " Help"

    While importing dv material from my 10 year old Sony DCR-TRV10
    I seem to be getting a stutter effect on audio in the record window while importing. I then tried playing back the material from my bin in the source monitor and had the same problems. Since the camera was still hooked up i noticed that everything played back from the source monitor through the cameras lcd perfectly. I suspect one or more of my settings are set incorrectly. Any help would be grateful. I know this should be the simple stuff.
    My sample rate is set to 32 kH, Audio format PCM (MXF), 16 bit sample depth.
    I tried searching through old posts but haven't found anything. Maybe I'm looking in the wrong place.

    A Couple things:

    1. CAPTURING, not importing. Two different processes.

    2. If you capture to your internal HD...do you get the same problems?

    Yeah, I get that.

    Try capturing to your internal. Let us know what happens.

    Makes no difference if captured to internal hd or external lacie. I hear the problem while playing in capture mode and recording in capture mode.

    Re: Newbie Post Audio stutter " Help"

    Not sure if you did so but your project audio sample rate should be set to 32k. Also, make sure you don't have something else plugged into the Firewire ports on your computer...like a iSight for example.

    I'm running 5.7 on a mac pro, no isight, the only thing i think i did do right was set the sample rate at 32.

    Re: Newbie Post Audio stutter " Help"

    Rather than starting a new thread, I'll just add on to this one.

    Not trying to capture/import, but during any and all playback (both audio and aud/vid) my audio stutters, and then gets out of sync. I can't seem to fix the problem, or find any answers online.

    Here's my info:

    (1 day old) MacBook Pro w/ 10.4.11, XPress Pro  5.8,  Quicktime 7.3.1,  no mojo, nothing else connected but my dongle . I'm editing off a 500 Gig Firemax external drive, through Firewire 400 into the laptop. My project audio is 32k, my VRAM is 512 MB...

    My timeline is uber simple. a few audio disolves, one video disolve, and just 90 seconds worth of footage dropped in. It's all old footage that was originally captured on 4.8, and 5.7, and did most of my editing with those, but now I need to do an overhaul on it, with 5.8

    Any ideas?

    Re: Newbie Post Audio stutter " Help"

    Have you confirmed that the Audio Project sample rate matches the sample rate on the clips in the timeline?  Is your display set to the native (highest) resolution?  Have you tried a test using the internal drive for your media rather than the external firewire drive?

    Re: Newbie Post Audio stutter " Help"

    I just checked, the clips sample rate, and the audio project sample rate do match. Both at 32. My display is at the highest resolution.

    and... crap. I just tried working on a new project, with 100% of my media on my internal drive, and I didn't have any issues. Any ideas on how to fix this? Getting a new external drive isn't an option at this point (though hopefully within a few months), and I don't have the tapes to re-capture the media to my internal drive. Could it be a driver issue with my old external drive?

    Re: Newbie Post Audio stutter " Help"

    Not with a Mac, no. Is that drive FW 800 or 400?


    Sorry, I see it's 400. Your drive needs to be raided to have any sort of throughput. How fast is that drive anyway? Is it, at least, 7200rpm?


    Looks like it is a drive issue so, short of speeding that thing up somehow, I'm not sure what you can do.

    Re: Newbie Post Audio stutter " Help"

    It's 7200rpm, I just checked to make sure. It's just under a year old, but has only been turned on for about 50 hours total, possibly less. You said it needs to be "raided to have any sort of throughput"... um, what on earth does that mean?

    So I guess I'll just have to somehow deal with the skipping until I can afford a new drive?

    Re: Newbie Post Audio stutter " Help"

    RAIDed means multiple drives working together to increase capacity and throughput. Redundant Array of Independent Disks.  But using DV isn't that much of a strain on a FW400 disk.  You're not capturing at 1:1 are you?  If not, sounds like that drive isn't performing very well at all.

    Most of the footage is from imported Quicktimes, but nothing that was captured was done at 1:1

    Looks like I'll be giving Promax a call :)

    Thanks so much!

    Re: Newbie Post Audio stutter " Help"

    What settings did you use to import did you import at 1:1 or did you keep them at say pal 420? Cause trying to play 1:1 out of your external may be the issue and even dumping all your media onto your internal may still be an issue seeing most laptop drives are 5400rpm...
