  1. I just burned a 1:45:00 mpeg file onto a DVD and it only took about 1/3 of the DVD space and the quality was noticably poor.

    When I burned the same file using Arcsoft Showbiz to took nearly the entire DVD. Problem is Arcsoft created terrible quality results with a lot of audio sync issues.

    TMPGEnc DVD Author did not have the issues but doesn't seem to be using the maximum disc space for quality.

    What size was your mpeg file to start with?

    I guess that showbiz re-encoded it and that resulted in the crap result. TmpGenc DVD Author would not do that, it simply uses what you give it.

  3. The Mpeg file was only about 850 megs but was One hour and forty five minutes in length. Given a 2 hour DVD wouldn't it take up most of the disk?

    According to available space I could have put approx. 6 hours of mpeg files on my DVD which leads me to think there are SP, LP and EP type settings similar to a VCR.

    Even teh back of my DVD+Rs confirms speed to length ratios. I imagine there is a option with TMPGEnc to select speed/length but I cannot find it.

    You need to lower the bitrate to get more video on the dvd. The speed to length ratios on your dvd+r are refering to a standalone dvd recorder which do have SP, EP etc... The longer you want to record the lower the bitrate will be. If your original mpeg is poor quality then you can encode at whatever bitrate you like but it will still be poor or even worse. There is an option in TMPEnc to increase/decrease bitrate.

    The mpeg was good quality, the resulting DVD was not as good.

    How do I change the bitrate and what is the new setting I want to treat the DVD like a 2 hour, rather than a 6 hour, DVD?

    It would take up most of the disc were your bitrate high enough (~4000-5000 kbps) DVD-/+R/RW discs have approx. 4.37GB of space on them. The amount of time that gives you is based on the bitrate (Low bitrate=smaller files=lower quality=more time on a disc, High bitrate=larger files=higher quality=less time on a disc). It's hard to believe that an MPEG2 file of only 850MB for 1h45m would look very good. If you wanted it to take up most of the disc, you should have encoded at a bitrate such that the file was around 4GB.

    At this point, you should reencode your source, because you cannot increase the bitrate of this mpeg and expect to improve the quality.

  7. It was a mpeg1 file.

    I'm still using TMPGEnc Plus 2.53.35.130 to convert avi files to mpeg.

  8. Sounds like you're making VCDs. DVD-Video is mpeg2 format.

    Doesn't DVD Author convert the file before burning?

    dvd author will convert the audio portion to 48 khz if needed but it will not change a dvd complaint video stream, vcd is a dvd compliant video. you need to take your source file and convert to mpeg2 in tmpgenc before you give it to dvd author as stated above.

    If your source file is VCD compliant (352*240 29.97fps for NTSC, 352 * 288 25fps PAL), DO NOT re-encode to mpeg-2. There is no point, you will only make it look worse.

    The reason your DVD looks worse than your mpeg-1 files is probably because you are watching it on a larger screen (your TV). Re-encoding will not improve it.

    If it has particular problems (noise, bad/incorrect colours, contrast, brightness etc), re-encoding with some filters MAY help, otherwise, don't bother.

    TMPGenc DVD Author DOES NOT ENCODE. So what you see is exactly what you gave it.

  12. Just wanted to thank you guys for solving my problem.

    First for recommending TMPGEnc DVD Author as a replacement for Arcsoft Showbiz.

    And second I was converting avi files to mpeg1 (VCD) and burning them as DVDs which seemed to be causing many issues.

    I realised TMPGEnc has the option to burn as MPEG2 and I did a avi to mpeg2 conversion and burned a DVD of very high quality without any video or audio sync issues.

    I appreciate you bringing a newbie up to speed.
