Capturing 4 track 12-bit audio

Hello,
I have DV tapes (not mini-DV) with 2 stereo tracks with 12-bit audio.
I want to digitalize my total DV video collection. Is this possible with Final Cut Pro ?

You'll have to make 2 passes on each tape. First pass capture video & audio 1&2. Second pass, use same in & out points, set deck/camera to output audio 3&4. Capture audio only. Place in timeline and line up.

  • 12 bit into 16 bit audio?

    Hi there,
    I have footage from a camera which, when capturing in FCP told me it was 12bit audio as opposed to the other footage I'd captured at 16 bit. On the FCP forum I was told that 48Khz was 16 bit and 32 Khz was 12 Bit...so I sent the audio from FCP into Sound track and highlighted all the audio and said "resample to 48KHz". I then relaid the track in FCP and I thought..happy days..but I'm looking along the time line in FCP and later on the mouths seem to be out of sync which makes me think it hasn't worked.
    Does anyone know an actual setting to ensure that the audio is indeed set to 16 Bit from 12 bit?
    Hope you can help (as always).
    Thanks

    I have a similar problem. I got a tape from a client and the audio was in 12bit and not 16bit and FCP does not like it and then the audio drifts and becomes out of sync. It also appeared to be a huge pain even to figure out how to capture in FCP with 12 bit audio.
    Here is my solution...
    #1 - Confirm that the audio is in 12bit. Put tape in camera and play it back with it not connected to the camera. Turn the "display" on so it shows the details of the recording over the video. The camera should be able to show you the bit depth of the audio.
    #2 - Capture the clips with 12 bit audio with Apple iMovie. Save out the project and quit out of iMovie
    #3 - iMovie will save one file to your hard drive. This is actually a folder with the details of your iMovie and the raw footage. Right clip on your iMovie file and select "Show Package Contents". This will open up the folder and then in the "Media" folder you will see the raw clips captured.
    #4 - open the clips in Quicktime Pro. Go to the "get info" and confirm the clips are captured with audio as "DV, Stereo, 32.000 kHz".
    #5 - convert audio only to 16 bit 48 kHz You can do this with Quicktime Pro or with another sound utility.
    a) with Quicktime Pro with your original video clip open select Window > Show Movie Properties. Then when that is open select the sound track and click Extract. This will open a new Quicktime window with only the audio file in it.
    b) now "export" this new audio file as 48 kHz 16 bit stereo
    c) open the new audio file and select all of the file with the play head then do a command "C" to copy it all
    d) go back to the original movie file and with the properties window open select the audio file and click on the delete button at the top of the window.
    e) position the playhead at the begining of the clip and select Edit > Add to Movie. This will paste your 48 kHz 16 bit audio in with the video track.
    f) save this movie out and import this into FCP
    Kind of a round about way of doing things but I found it pretty easy although cumbersome.

  • Advantages of 12 bit audio over 16?

    I am getting ready to shoot something with four cameras. I borrowed these cameras from friends, and one of the first things I did was to check and make sure 16 bit audio was set. I once shot some video with my camera and had some trouble in the capturing process in Final Cut Express because my camera was set to 12 bit, and I had the easy setup set for video shot in 16 bit. Now when I borrowed my friends' cameras, they were all set to 12 bit. I reset them to 16, but I am wondering why all these cameras SEEM to have a default setting of 12 bit audio (I don't know for sure if this was the default, but they were all on that). Are there any advantages to shooting with 12 bit audio over 16? Thanks in advance!

    +" ... wondering why all these cameras SEEM to have a default setting of 12 bit audio ..."+
    The manufacturers set the default at 12 bit because it makes it easier for them to support their marketing claims about the "4 audio tracks" and "audio dubbing / voiceover" capabilities of their cameras. They know their target markets and the concept of being able to record 4 audio tracks and do voiceovers in the camera is an appealing-sounding feature to the vast majority of video cam buyers - even though they'll never use it.
    For someone who wants to edit video, there is no advantage to shooting with 12-bit audio. And it can present a lot of disadvantages. Do yourself a favor and always shoot with 16-bit audio.

  • 32 bit audio unit bridge unexpectingly quits

    I've just updated to Snow Leopard and I've been using Melodyne to fix vocals. When I used Melodyne on the first 3 vocals, everything in Logic was functioning fine but when I try to import the last vocal track into Melodyne, the 32 bit audio unit bridge unexpectingly quits. I've tried quiting and re-opening Logic and the same problem happens at the same spot. On the previous 3 vocal tracks that I fixed with Melodyne, I have already bounced those tracks in place and have got rid of the old tracks. So, the Melodyne plug in is only open on the last vocal track. It seems strange that my Melodyne plug in was working fine with the 32 bit audio unit bridge (as are all of my plug ins) until now.
    Any advice anyone?

    If you are running Logic in 64-bit mode with a variety of plugins, you're going to have to realise that things probably won't be stable until updates get released.
    The AU bridge is a workaround for the transition period, and one that many third-party developers haven't had much of an opportunity to test with their products, so you may well get funky behaviour in certain things.
    If you're really stuck, go back to 32-bit mode for your edits, and it's worth contacting the developer of your plugins to see what they say about AU Bridge and 64-bit compatibility.

  • How to check for 12-bit versus 16-bit audio?

    Several hours of my first digital recordings were done with 12-bit audio (factory default). Later I changed the camera's settings to 16-bit, but I'm not sure when I did that.
    Is there a way to check the audio bit-rate of a clip if the camera doesn't display that information? I'd like to periodically check the imported clips to determine when I started recording with 16-bit audio, because at that point I'll need to change the Easy Setup settings in FCE.
    Thanks.

    Unfortunately not. FCE assumes you set the easy setup correctly and will capture the audio as if it's that sampling rate. It's unfortunate that some cameras don't display this. If you capture fairly short segments, around 10 minutes, you should be able to get away with it however, especially if you don't capture across a TC break.

  • 12 bit vs. 16 bit audio settings

    Any preference as to which is better or why choose one over the other?
    JVC DV camera has settings for both and I'm curious to find out what others think.
    Thanks
    Gary

    12 bit audio settings allow you to record 4 channels on the DV tape: 2 while shooting and additional 2 later if you edit with the camera. Since however 12 bit samples provide worse quality audio than 16 bit samples and I expect you'll use FCE for editing (not the camera), the 16 bit (2 channel) audio is recommended.
    Remember that with 16 bit recording you have to use the 48 kHz settings in the Easy Setup for capturing in FCE.

  • Dv converter and 32 bit audio possible?

    In order to use all 4 mics on my canon xl2 video camera, I have to set the audio to 12 bit, 4 channel I am recording live directly to my computer, so I need to use a setting that is non-controllable to the video camera. I believe the only easy-setup setting like this is DV converter, which is does not have the 32 bit sample rate and so does not record two of the mics. So, is there any way to get the 32 bit audio sample rate on the DV converter setting?
    -Eric

    I don't think this will matter as FCE only allows the first stereo pair to be captured. The second stereo pair could be dubbed to another camera then captured.
    Check your camera manual (fine print), many cameras won't send the second stereo pair out over firewire.
    Pretty annoying stuff when you want the lot.

  • Capture from different video and audio sources ?

    Hey guys, I'm running Adobe CS4 Master Collection.
    In the past I've used Premiere to record the video and Soundbooth to record the audio. Then I would import the recorded audio into premiere.
    Thinking about the workflow this seems kind of long winded, really what I should be able to do is record the audio from my video camera and the audio from my microphone (not video cam audio), at the same time within premiere.
    Just wondering if anyone has a way of doing this ?
    In the capture screen options it only allows selection of the video source with the audio automatically coming from the video camera - not what I want.
    Any help would be appreciated. Cheers.

    Jason,
    Welcome to the forum.
    Unfortunately, this was posted to the Premiere (not Pro) forum, and belongs in the Premiere Pro forum, as you have CS4. The best reason for that is that there is much more traffic out in the PrPro forum, so you'll get more responses.
    Now, to address your question: I see your normal workflow as being the best one. You are talking about the Video from your camera and then narration. Doing them as separate operations will be the easiest and the best, as they are, well separate operations.
    One possibility would be to hook your mic to an XLR input on your camera, preview the footage and record your additional Audio Track to the tape, or card. However, you are then faced with having more than the 2 origianl channels of Audio. You would need to use SceneAlyzer Live (for SD material), or HDVSplit (for HD material), to Capture those additional channels of Audio for use in PrPro, as it will NOT Capture them.
    I'd guess that the time to do that sort of workflow would be as long, as doing it your way. Also with your way, you can redo botched narration much more quickly.
    Maybe someone has another method, to run both Soundbooth and PrPro at the same time, other than on side-by-side computer, but you'll still have the issue of bothched narration - gotta' get it 100% the first time, or you'll be really playing "catch up."
    Good luck,
    Hunt

  • 24-bit audio recording in iPad?

    A couple of hardware manufacturers claim it's possible to record 24-bit audio via USB/CCK on the iPad in the latest IOS update (Apogee and Lexicon) into apps like Garageband. Has anyone tested this?

    Just an addition.  I get this error message whenever I try to play one of these captured clips.
    "Additional software is required for QuickTime to playback this media.  It may be available from the QuickTime Components page."
    I'm not sure what component might be missing as it's supposed to be 24 bit uncompressed audio and not some third party codec.

  • 16-bit and 12-bit audio question during editing

    This will sound more like a camera question, but I didn't know if it will be part of editing video with Pre7. I read this on a web blog and was wondering if there is any truth to it. “Mini-DV amateur video cameras can record sound in 12-bit or 16-bit audio. 12-bit audio is used when you want to lay down another track on the video tape. But 12-bit audio can start to drift out of sync with some editing software. 16-bit audio is a stable setting.” Also, what is meant by laying down another track on the video tape?

    Paul,
    Yes, to the intended purpose of the 12-bit. Now, if one is going to do any editing, I'd strongly recommend not adding that soundtrack/musictrack to the tape. It will cause all sorts of problems in the edit, and is designed for one, who wishes to just show the tape on a TV.
    That's two votes against 12-bit Audio.

  • Question about 12 bit audio

    I have an in camera edit to do for school and I had planed to dub over the video with new audio. I can't because the audio is in 16bit. I thought maybe I could change the settings on my camera, capture the footage in Final Cut, then print to video (my camera now in 12 bit mode) and solve all my problems.
    Final cut however seems to be automatically printing my audio as 12 bit. Is there any way I can change this. I have a 2 minute clip that I need to re-record as 12 bit audio so that I can do an audio dub.
    Any suggestions?
    Thanks,
    Matt

    1. Yes. Quicktime Pro, iTunes or third party audio editing software such as Peak can resample to 48khz/ 16 bit.
    2. It would be best if you can get everything in the timeline to be 48khz/16 bit.
    3. See #2.
    Dope slap these fools who bring you 32khz stuff. Charge them MUCHO extra for your time.

  • PP CS4 - 12 bit audio out of sync - bane of my existence

    I've searched this forum and across the web but have not found a solution for my specific problem...
    I'm running a Mac Pro OS 10.6.3 with PP CS4.2.1 The audio on these tapes is 12 bit, so my sequences are set to 32000 sample rate (I have not been able to find a "12 bit audio" setting anywhere...only a choice between 8 bit and 16 bit audio...and all my research has led me to conclude that 32000 vs 48000 sample rate is the only setting I can adjust to capture 12 bit audio. If there is a better solution, please tell me.
    When I capture 1 hour tapes (as Quicktime files) from my miniDV cam, everything appears fine with audio and video sync as I watch the footage in the capture window. Once the tape is successfully captured (without any dropped frames), the audio files "conform", and when I play the 60 minute clip back in the preview window or drag it into the timeline (32000 sample rate sequence for 12 bit audio) the audio goes gradually out of sync with the video.
    To be more specific, the audio is in sync at the beginning of the clip, but by the end of the 60 minute clip the audio is well out of sync (perhaps as much as a second).  Does anyone have experience solving this issue? It seems to me that the problem arises from the audio being 12 bit, although I'm happy to be proven wrong.
    Thank you in advance for any insight or help.

    Thanks for the help, Gonzchi. Unfortunately, I have already been capturing the audio from my tapes at the correct sample rate (32000 khz) and at 16 bit depth (I've been unable to find any settings allowing me to specifically select 12 bit audio so I've been using 16 bit capture settings), and I am having these sync issues.
    Because I'm using the same sample rate as the tape for capture (32000) and all the audio appears totally in sync with video as I preview during capture, I figure that somehow the problem occurs when the audio files are processed after capture from the original 12 bit source to the 16 bit output.
    Does anyone have suggestions for settings or procedures I can try? Perhaps some way to adjust the audio files as they are converted?
    Thanks for the help. Much appreciated.

  • 12 bit audio synch Q?

    So my mom recorded this video for me. on the camera(canon Elura) it says 12 bit on the screen as it plays. It also records in anamorphic. So i hve been trying to capture in dv ntsc anamorphic . .whis works fine except that after i capture i get an error message saying something like "ther was a problem capturing audio, your audio may not be in synch." Offten the audio isnt in synch, and sometimes it looks like it might be but i cant tell. It seems like final cut captures at 16 bit. .. . .how do i capture the audio for this video???? Thanks for your help.

    You need to create a new capture preset that changes the audio rate to 32 kHz 16 bit for 12 bit DV recordings.

  • 12 bit audio synch issues

    Hey all. I have a queation regarding 12 bit audio synch problems. I have digitized a tape recorded with 12 bit audio and am just now coming into video/audio synch issues and was wondering if anyone might have a workflow suggestion. Soecific questions are -
    1 - Can I export the troubled clips to quicktime/ resample them at 16 bit and reimport?
    2 - Some of the clips I already have edited and are in synch, do I need to correct them as well or will final cut do that on export?
    3 - If I get a 12 bit/16 bit mixed bag on my timeline, can I export the mix to 2 track and convert before exporting it to compression?
    ANy suggestions on how to work through this would be appreciated. I seem to have a lot of people coming to me with this setting and would like to know of any viable workflow solutions.
    Thanks

    1. Yes. Quicktime Pro, iTunes or third party audio editing software such as Peak can resample to 48khz/ 16 bit.
