    I have a P4 3. Ghz, I am using Dazzle hollywood DV bridge using Uleas Video 7 SE. I am capturing a movie from Laser Disk to hard drive then burning to DVD-R. Upon playing the DVD on the PC or DVD player, the video looks abit jittery, any thoughts. I am capturing with NTSC DVD with a bit rate of 5000. The movie is about 98 minutes. Help

    Hi gondey99, welcome to aD,

    My first question is what brand of media are you using. What you describe is a classic of poor quality media -

    Let's take Memorex as an excellent example as DVD media goes, 90% of Memorex is sub-standard as far as DVD backups are concerned, figures as high as 50% coasters have been reported (One member bought a stack of 50 and got 23 good burns.), not what I would call an impressive record. Memorex made a name for itself with their magnetic tapes (VHS and audio cassettes) and have been living off it ever since. There are 4 different companies that manufacture Memorex DVD's BTW and product quality varies widely as you might imagine. Only 10% of the Memorex out there, those are discs manufactured by Mitsubishi in the 25 pack spindle , and they're the exception – they are the good ones. It's easy to see now why the quality of a big-named company can’t be trusted - “ Who’s making your Memorex tonight ?”

    Is it just Memorex ? No ! I just used Memorex as an example, Princo, Orange Pack, Great AZO and most "store" discs aren’t all that suitable as a DVD backup media – that’s why we are specific in the type of media we are recommending.

    1. * Cheap media freezes, skips, pixelats and may refuse to be recognized by both burners and players :-( Besides "Freezing", "skips" many times you’ll get a “Cyclic Redundancy error” or an "I/O error". This message can mean that your discs are scratched or dirty, it can also mean that your burner won’t accept your “cheap” media :-(
    Another problem which, “Pops up” is a “*Power Calibration Error”. This can stop you right in your tracks and most often is caused by, Yep, you guessed it, inexpensive media. *A “Power Calibration Error” can also be attributed to the Optical Components of a DVD Writer, though this isn’t usually the case. Trying to shut down your software and ejecting your DVD then restarting your program and re-inserting the same media recently cleaned has been known to help in some cases.

    Orange Pack, Princo, Great AZO and 90% of Memorex plus many others are just not that good for DVD burning. Those same discs however, are quite good for your MP3 music, picture archives, Spread sheets and Data..Even DataSafe G04’s made by Ritek have been reported as an inferior quality media and are evoking that “Oh no, I shouldn’t have gotten those.”

    What we are suggesting is to download this DVD Identifier to find out who manufactured your DVD and if it's a decent quality.

    http://dvd.identifier.cdfreaks.com/

    Once you have your disc identified, click the "More information" icon and see what information you're given. if you're not sure of the quality, come on back and we'll check it out for you -

    2. A good grade, Hi-quality media is needed for DVD reproduction ! RiData, Sony, TDK, "Branded" Ritek G04's or "Branded" Verbatim Data Life, Verbatim DataLife plus, Taiyo Yuden's and generally, almost any discs manufactured by Mitsubishi are excellent bets. Among the better discs we're looking for, any media boasting "Advanced Metal AZO" - BUT it must say "METAL" AZO !, this indicates a superior dye and dye application on a good composite disc, while they are sometimes a bit "pricey" they are just the type of media we're looking for to do our DVD backups, Prices online from Meritline.com OR Newegg.com have gotten Ritek G04 starting at about a $ .45 (USD) a disc –

    For DVD backups, purchasing inexpensive media or even average media is a gamble, some people win BUT the majority lose, they lose varying amounts true but, they still lose :-(

    Using good grade media can guarantee you one thing to an absolute certainty; it surely cannot hurt.

    In an effort to clear the air, when I speak of "Cheap" or "Inexpensive" media, I'm not referring to the price you pay at the counter - I'm referring to poor quality control used during manufacturing and the quality of the dye, dye application or composite type used. I'm not saying it won't burn - Some may burn, some may not. It's quality is inconsistent, meaning it's not dependable.
    When I say "Branded" that means that when you pick up a disc in your hand, it says "Ritek" or "RiData" on the disc itself. The monetary cost of the media we recommend many times is cheaper than what you are purchasing now.

    We like to verify our information prior to recommending things. There are certain things we look at. For instance, when their dye and dye application are listed as unknown, this almost guarantees us they are using whatever they can get at a cheap price. Companies that use quality materials like to BRAG about it, naming names and staying with quality manufacturers who produce their media.

    Using DVD identifier and MediaMatch can help you find out a lot about what you're using. Purchasing your DVD media online can insure that you're getting quality merchandise at a good price. Shopping wisely will save you time, aggravation and money.


    I hope this has been of some help to you -

    Cheers,

    Pete

    Thank your for your response. However I should have stated this first.....But I just noticed this after I had posted.

    Even the capture mpeg file itself is jittery. When it is a motion scene with people, the people look jittery if you will. Non- motion scenes look ok. I hope I am explaining this well.

    If the original is OK then it's a matter of getting the settings correct when you render it. If the files aren't encoded then you should Use Mpeg2 instead of Mpeg1 because it is a better format and maybe "Bump" the bitrate up to about 1500kbs. This will increase the Quality quite a Bit and still allow you to get 6 hours on a DVD if you use a audio bitrate of 192kbs....

    This DVD Format is Called SIF or CIF format and not every DVD authoring program will support this DVD format especially Cheapo DVD authoring programs. Both DVD Lab and TMPGEnc DVD Author will support this DVD format accept with DVDLab you have to use Mpeg2....

    You can just encode your files to VCD but use 48000HZ Audio and then author them to a DVD with no problems. That way you could fit 6+ hours of VCD quality Video on a DVD....

    When you encode a low resolution VCD file to full resolution DVD Format you loose a lot of quality because you are resizing a small resolution to a large resolution which is were you loose all of the quality, but there is no need to re-encode VCD's to DVD because VCD's are already DVD compliant accept for the audio which needs to be 48000hz to be on a DVD......

    a Note about settings in the GOP Structure settings:

    Set the "Output Interval for Sequence Header" to "1" and this will Put 1 sequence header before every GOP...
    You actually get Better quality when using a smaller GOP but it can cause a slightly bigger file size...
    This is the GOP I use:

    Number of I Pictures in GOP: 1
    Number of P Pictures in GOP: 4
    Number of B Picture ins GOP: 2
    Number of Frames in GOP: 15
