    Regret all the confusion.

    First we have the raw footage, notable for the double vision of the moving fencepost, filename: Rawfoot

    Videotape on DV- brothers racing Dirt Circle Track. Seek best DVD burning solution- maybe to bring to track. Also seek truly great book explaining DV-DVD burning stuff, eg, encoding, "how to".

    Second and finally, we have the DVD image which was burned on the LG standalone, filename: DVDimage. It is noteworthy in that there appear four faint fenceposts rather than two:

    Am starting to catch on here. If I had a Liteon (the burner on my PC) DVD versus raw image, this would be more productive. I will keep my eye on this forum for a few, but also try to load up both a raw and DVD as the PC creates, that is where you could give some adjustment specs... I did not anticipate the level which you (all?) can discern what needs adjusting.
    Thanks.

    While not wanting to be argumentative, I would only trust that to be the case if the original images were identical. Since they have slight differences between them to start with, there will likely be slight differences in the JPEG artifacts introduced as well. But I will agree that these differences will probably border on nonexistant. It's just that when you are trying to analyze minute differences such as these, eliminating all other sources of discrepancy will result in a more accurate determination.

    JBlackTD was unable to view the video clips with Windows Media Player 9. Says:

    "Windows Media Player encountered an unknown error" (3000CBR) and:

    "Windows Media Player cannot play the file. The file is either corrupt or the Player does not support the format you are trying to play" (the avidv file)

    Coalman, Bobkart, EdDV,

    1) Captured in Studio10. Burned in Studio 10 on the LG. Worked okay. Same on the Liteon in the past, and as I recall, there was NO mention of finalizing a disc via Studio10 (possibly automatic). Many more DVD players would play the DVD I made with the LG, and it was clear when I finalized.

    2) Do not know if PowerDVD can grab frames or even see the DV tape, do not see how. (If it does, just say so and I WILL figure it out)

    3) Ironically, the actual burner (the LG standalone) was returned, so I cannot actually look at the finished DVD (!!!!) on Studio, only through Power DVD. Point: It is useless to compare images if one comes from Studio, the other through PowerDVD, I suspect?.

    4)Perhaps because it is late, I cannot find the raw DV tape for the last incidence of burning on my PC (through the Liteon). Is it okay if I just ... videotape a milk carton tomorrow, and burn to DVD, and grab frames (or similar) ? I can do this later. I have Nero, PowerDVD, and Studio10, all apparently burn, compress, etc.

    5) Thank you for your tolerance, it does not please me to waste your time like this.

    6) somehow I got... moved... to a different thread in Videohelp.com.. where Coalman and Bobkart were discussing the same music stage image, and the video clips were available, except to me, even if I clicked "Save as". I havent the foggiest how I got there, nor why it is detached from this thread, nor where that "broken thread" went.

    G'night, and thanks again.

  9. PowerDVD can play DV-AVI files as far as I know.

    The PowerDVD-versus-Studio10 image comparison is hampered by Studio10 stretching them to make the PAR=1. This requires correction back to 720x480 before an exact image-to-image comparison can be made. Such comparisons will not be useles, but simply less accurate due to the stretching/shrinking process, which can introduce differences in and of itself.

    I do these kinds of comparisons on video by the way, take some DV-AVI, encode it to various MPEG2 bitrates for DVD, then run them both through a video-differencing application I wrote. That differecne is then measured (by another application I wrote) such that a numerical value can be associated with it that represents the differences, and those measurements can be compared to help determine which encoding is better. I intend to use it, for example, to see if a standalone DVD Recorder can encode a better result than a software encoder, and how different those rsults are (I think we can all agree that he software encoder has the advantage there).
