    what will yeild the best quality video using TMPGEnc, CQ, CBR, or VBR, if size of file is NOT important, can I just max out the Bit rate with CBR option? (will this give me the best output, without regard to file size?)

    My strategy is to have TMPGEnc, apply the filters for color correction to it, then use another encoder (that I am more familure with) to make it fit a single layer dvdr.

    Sorry if this doesn't sound graceful, but I am not a 100% on using TMPGEnc to get it to the right size (and still maintain the quality.)

    I am still learning.

    Thanks for the help!

    I don't understand here, is file size important or not?

    CBR at max bitrate will give you the best quality you can achieve with your source material. Of course this is assuming all other settings are maxed out too! It will probably be quite wasteful though and the same result could be achieved with 2-Pass VBR (if controlling file size required) or CQ (if known filesize NOT needed). Either will give a smaller file than a High CBR.

    Again, not really sure I completley understand this. Correct me if I am wrong. You intend to encode to Mpeg-2, Highest possible quality, in TmpGenc, to simply make use of the colour correction filter, then re-encode with some other un-named mpeg encoder to your final product. If this is what you mean it just doesn't make sense. This will take much longer than is needed and will introduce the high possibility of unneccesary quality loss due to multiple encoding. This is normally reccomended avoided at all costs.

    Either use TmpGenc for the whole thing, its generally considered one of the easier encoders to set up, or use something like avisynth or virtualdub and one of a selection of available colour correction filters and then frameserve to your encoder of choice.

    Hope this helps.

    Thanks!

    Let me ask you this way. I have several applications, but not much experience in doing this.

    The "THIS" is trying to color correct about 1.5 hours of video file, in mpg2 format. I think I was going to use TMPGEnc to apply a color filter, but I think instead I will use Vegas to apply a color filter to the project, then output it, to an uncompressed AVI file.

    At that point, I will use TMPGEnc to make it DVD5 size or perhaps I will use TDA to author a very large DVD ready folder, and use Pennicle Instant DVD to size it down to DVD5. (I really have had excellent results with instant DVD, and I am still learning about TMPGEnc. & so far, I have mixxed results using TMPGEnc. I am sure TMPGEnc would do better, but I am still learning about how exactly to do this.)

    on TMPGEnc, I really don't know how to optimize the settings. I read a few post here and there seems to be some question as to using either CBR, or CQ, or even 2-pass VBR. (although most seem to say CBR at high rate will give best quality.)

    so how do I balance all of this and make a single DVD MPEG-2 disk which has the best quality using TMPGEnc?

    anyway, I do get the statement about recoding twice. I like to encode using either 1 or the other. (and I suppose using vegas to do the color correction, and outputing as uncompressed AVI, will work for this purpose.)

    any advice? tell me what ya think. Thanks in advanced!
