  1. Hey, I have bought a FireWire PCI-e adapter and I have been transferring miniDV tapes via the firewire port (4-pin to 6-pin) on the SONY DCR-HC52E.
    I have used both WinDV and ScenalyzerLive utilities to capture the tapes (AVI type2). Both are great tools but I've decided to stick with ScenalyzerLive.
    I have noticed an orange/yellowish vertical line present on the left side of the recorded videos and it appears all the time even when previewing the camcorder's live-feed camera. Is there any fix for that or it is considered to be normal?

    Even when I tried to transfer Hi8 tapes using Sony CCD-TRV27E and passthrough A/D converter using my other SONY DCR-HC52E, the vertical line still appears.

    Is this caused by the FireWire PCI-e adapter? or the FireWire cable? personally, I don't think it is related. I've been using the 4-pin to 6-pin, but I also have a 4-pin to 4-pin cable but haven't tried it, and I don't think it would make any difference, to be honest.

  2. There's nothing unusual about bad colors at the edges of the frame with analog camcorders. In those days you never saw the edges of the frame -- they were hidden by the TV's overscan. Crop them away or cover them with black in post.

  3. That's weird. I have never seen artefacts like that on my DV videos. You have two HC52E camcorders? Or you used the same one for native DV and for A/D conversion? My guess is no better than anyone else's, but I would think it is either the camcorder or something wrong with Firewire. Then again, DV frame is 720 pixels wide, and for 4:3 frame you need only 704 of them

    The FireWire cable and the PCI-e adapter used cannot cause this.
    It must be by design of the HC52E. Is it something to worry about? No. I had a MiniDV camcorder that would record two or so black lines at the top. As jagabo says it is well within overscan areas and is therefore not considered an issue.

    Yes NTSC miniDV is 720x480 full active frame no padded pixels with a PAR=8/9, But 704 is for analog sources only and has PAR=10/11, if you crop miniDV to 704 you change the aspect ratio, not noticeable to most people but it's there, unless he is using DV as a passthrough.

    It's probably bad caps at the chroma processor making it shift the chroma to the right by few pixels. Jagabo posted a script before for analog camcorders where the chroma shift was from the right to the left.

  6. DV from camcorders may have picture all the way to the edges of the frame but the PAR is 10:11 just like rec.601 analog video capture. It's been discussed and shown here many times.

    Vegas does not agree with you.

    I agree when creating a DV file from an analog source, but what about the camcorder's own CCD? I think the only way to find out is doing a circle test like I did for V8/Hi8 camcorder and use both SAR's and see which one provides a perfect circle, the only problem is I don't have a minDV camcorder, I have a DV/HDV/DVCAM studio deck, What a bummer.

    Edit:
    I dug up some miniDV transfers I have on my hard drive and they are all 720x480 4:3 aspect ratio with PAR 8/9 confirmed by several media players. I would like to post a sample but that will derail the thread, maybe for another topic.

    It's the same.

    It's been done. I've done it myself. And confirms the 10:11 SAR.

    The media players are wrong.

    VirtualDub2 lists 10:11 for DV-NTSC.
    One should not blindly trust media players as these - when seeing 720x480 and 4:3 - simply assume the generic DVD mpeg2 PAR of 8:9 by default, or "calculate" it like 480/720x4/3 = 8/9.
    One more circle test should be easy though

    This turned out to be a big stinking controversy in video history, for the sake of not hijacking the thread please respond in this thread.

  12. Here's one quick dirty method of removing the orange discoloration:

    Code:
    AviSource("scene'20090708 20.23.44.avi") 
    
    patch = Crop(6,0,4,0).BilinearResize(6, height)
    patch = Overlay(last, patch)
    MergeChroma(last, patch)
    QTGMC()
    The colors from near the edge replace the discolored pixels at the edge.
