please help - Windows Movie Maker

  1. P4 3.6ghz
    Windows XP Media Center Edition
    AverMedia AverTV MPEG Video Capture

    I'm trying to encode some old video tapes from my vcr to my computer. I have
    a coax cable from the line OUT of the vcr to the line IN of the tv card. I
    also have a red/white rca audio connection from the OUT of the vcr to the IN
    of the tv card. I start Windows Movie Maker and get video only, no audio. I
    tried all the audio configurations (microphone, wave/mp3.. etc.) and still
    get no audio at all. Suggestions?

    The AverMedia card should have an audio output. There should have been about
    a 6" cable with the card. You plug the cable the output from the card (the
    jack closest to the coax), and into the line in on the audio of the PC
    (usually blue), then set the sound to record from the Line In.

  3. OK all I see on the tv card is FM, coax, svideo and the red/white audio in
    ports. I don't see an audio output.

    Oh - you have the FM model. It's different than mine. Try putting the audio
    out of the VCR to the line in of the PC rather than the card. That's just a
    guess, since I don't have that card to try it with.

    The coax should carry both audio and video.

    then why would you have rca in?

    use the coax or the 3 rca inputs, not both together.

    The card I have does not interface internally to the PC sound card. It has a
    stereo 1/8" phone jack for audio in, and one for audio out. The audio out
    always goes to the PC line in. If I use coax, I don't use the audio in on
    the TV card. But if I use composite (yellow RCA) from an analog source, I do
    use the audio in. It probably does that so it encodes the sound with the
    video when recording, but the playback sound still goes through the audio
    out into the PC. So as I think about it, putting the audio from the VCR
    direct to the PC line in might not allow the audio to be encoded with the
    video. Hmmmm....time to Google <g>

    You don't use both, either coax or rca (this is the problem)...the vcr is
    analogue out anyways.
    My PVR uses a line in for audio to the PVR card, if you didnt, you would
    have audio sync issues, as the card has about a sec lag...

    True. With the card the OP has, I'd suggest he switch to using the composite
    input and RCA audio instead of the coax anyway - probably better signal
    quality.

    Open the 'Volume' applet in the system tray (bottom right) (or Control
    panel, Sounds and Audio devices, Volume tab, Device Volume, Advanced button)
    Options menu (top left)
    Properties
    Check for your sound system in the drop down selection box at the top.
    Make sure there is a tick in all the relevant input sources in the lower
    window (eg mono mixer, stereo mixer, line input, wave, aux etc.....) Close
    properties
    Check for 'muted' inputs'
    Reopen Options, Properties
    Click in the 'Recording' option (middle of window, under 'Playback', the
    available inputs will change in the bottom window.
    As for Playback mode tick the relevant input options, close properties and
    you should now see the 'Recording' inputs listed.
    Place a tick in the appropriate input box (stereo mixer is a good one to
    start with)
    I find it convenient to open two Volume control windows when 'debugging'
    sound issues, one set to playback the other to recording options.

    Do be aware under some circumstances 'feedback' can occur giving the same
    effect as no sound. This is when the output of one source is fed back to
    it's input causing the signal to be amplified till it 'flat tops'. (Suffered
    this with a USB Video capture box here, took me a couple of hours to find
    it)

    Cheers
    Paul.

    The other thing I'd suggest is (having used this AverTV card) is get a
    better card <g>. Mine, at it's very best, sucks. Frequent issues with voice
    sync (time lag), jumpy output, barely adequate resolution, bundled software
    was trash. I have a computer with at least three times the recommended
    system requirements, and it still runs poorly. Next time, I'm gonna shop
    around more and spend some real money <g>

    That's not feedback - that's more like phase cancellation. Feedback is that
    nasty squeal that occurs when an open mic signal loops back through the
    amplifier.

    MM is probably configured to get its sound from your sound card. Go to
    the audio configuration area and make sure that the audio on the capture
    board is the source of your audio.

    YEAH - now *that's* what I'm talking about! My next one will have remote
    control. I did add 220 gigabytes extra storage to my PC, but now that I'm
    making car payments again, I don't have near the "flexible" budget I used
    too <g>

    Hi Toolman

    No it was feedback, well in this case anyway.
    The tiny bit of sound I could hear as the capture box came on gave me the
    clue.
    It started of at normal levels but immediately the levels shot up taking the
    meters to the max where they stayed.
    Phasing errors would have stayed at the same level.
    Pulling one of the input levels to 0 gave me a brief sound blip again as it
    all came down.
    Can't remember which 'input' I muted to fix it (probably setup related
    anyway)

    The feedback squeal you refer to is exactly what was happening, but at a
    frequency that was beyond hearing.
    One has to remember this is happening within the PC sound card making signal
    paths short.
    The 'squeal' one usually hears from a PA for example is usually within the
    audio range because of the longer paths between input and output (mic and
    speaker if you like)
    These longer paths naturally limit the upper frequency the feedback can
    reach.

    As for Phase cancellation, no.
    Reason, lessons learned trying to build phasing SSB transmitters in the days
    when sideband filters were diabolically expensive.
    100% Phase cancellation can happen in "Theory" but believe you me over the
    range of normal hearing it is very difficult to get beyond a few 10's of db
    cancellation except in one relatively narrow range.
    Mind you with modern DSP's I guess anything's possible now.

    Did have one sortof 'phase' job a few years ago.
    Local Music shops sound system, complaints of low or no vocals on CD's
    played thru Stereo speakers, no problem through CD player head phone socket.
    Cause was the DIN lead between CD player and Stereo had an open circuit
    ground lead.
    The 'Music' was coming through sortof ok because the difference signal
    generated between the left and right track. i.e. Violins left, Violas right
    etc, i.e the left and right channels were out of phase with one another. The
    clue to their 'difference origin was determined by listening on the Stereo's
    headphone socket showed it was 'mono'
    The vocals were however at similar levels on both CD tracks. Because they
    were 'In Phase' with one another on each track they could not generate a
    large 'difference' signal at the Stereo's input, hence the 'Vocal' was at a
    'very' low level, note it was 'low' not 'silent'.

    OK enuff ramblings for a Sunday nite.

    Cheers
    Paul.
