  • CS6 keeps dropping audio on my Mac

    Posted by Kat Hayes on March 15, 2014 at 8:21 pm

    Using a Canon AVCHD camera, every single clip I ingest results in dropped audio. It doesn’t matter if I close the program and reopen it, it is always gone. Is there any fix for this?

    Thanks.

    Do you mean there is no audio appearing on the sequence, or it is dropping out on playback?

    Is the audio present if you play it back in QuickTime?

    How are you importing the clips into Premiere?

    The clips play fine if I ingest them directly into the QT Player, the audio is on the clips and plays and exports when I use the QT player to encode the clips.

    However, I use the Media Browser in CS6 to navigate directly to clips on my SD card, I load them into the Source Window. When I play the clips in the Source window the audio will play, but at some point drop. When I drag the clip from the source window to the Timeline the audio is gone there also. When I export/encode the clip the audio is also missing. I’m not quite sure is there is a pattern with regards to where the audio drops out in CS6, though it always seems to happen.

    1. Any suggestions?
    2. Is there a different way I can get the clips into CS6?

    Thanks!

    https://Wwwwaaaaait a minute. Are you trying to play the files straight from an SD card? I wouldn’t be surprised if you had performance problems then. Copy the card with the whole file structure intact to a fast(er) harddrive.

    I currently have an SD card with around 45GB of video on it. I do not want all of the clips on it, though I have not had a chance to go through them all yet, so I have been shooting clips, and selectively ingesting just those clips that I need straight from the card. I do not want to copy all 45GB and take up that space.

    1. Are you saying that this is not a good idea? The SD card may not be fast enough to ingest straight to the Mac, resulting in my audio dropouts?

    2. If so, is there a way to somehow just copy portions of the SD card to my Mac or an external hard drive without copying over EVERYTHING on it?

    Thanks!

    With AVCHD, it IS possible to isolate the clips you want and just copy those, but due to the file structure, it can be quite a laborious task to do this. Plus, previewing the clips can also be really slow as the SD card isn’t fast enough to play back the clips.

    If you are wanting to edit, you will need to transfer the selected clips to the hard drive.

    Personally, I would copy all of the clips to the hard drive and then go through them and work out which clips you require. You will then be able to delete the ones that you don’t need.

    Alternatively, you may be able to browse the card using the media browser in CS6 to preview each clip, then just right-click and click ‘import’ on any clips you require. However, doing this may result in the kind of playback problems you have experienced so far.

    1.) If I copy all of the clips to the HD, how do I then delete the ones that I don’t need?

    2.) After importing the clips I require, where are they saved to? What format are the brought in? I’m guessing no compression is applied?

    Thanks!

    1.) If I copy all of the clips to the HD, how do I then delete the ones that I don’t need?

    It is a bit of a time-consuming process, but basically what you need to do is note which clips you are using (as denoted by the clip name) then manually delete the ones you don’t require from the folder. Your AVCHD folder will be structured something like [Root folder] > PRIVATE > AVCHD > BDMV > STREAM and all of the individual clips can be found in there.

    2.) After importing the clips I require, where are they saved to? What format are the brought in? I’m guessing no compression is applied?

    They will be imported natively into Premiere, which means that the files will remain as they were on the camera (probably .MTS).

    This method CAN be used, but in all honesty the safest advice I can give is to get an external drive of some description (preferably something fairly fast like a USB3, if possible) and copy the entire contents of the SD card onto it to ensure that everything is backed up, and work from there.

    I have lost video files before, and it isn’t pretty!
