  • So: the G400 will capture for DVD!

    I guess all you experienced folks already know this; but some one answered one of my postings saying that you don't have to use a 720x576 (pal) capture for DVD, that you can in fact use a 704x576 (G400 top resolution) mpeg2 video and it is DVD compliant. Well it would appear this is true.

    I captured at 704x576 using mjpeg (75% quality-under 2mb per second) and used Ulead moviestudio to convert the file to a 704x576 mpeg 2 video: ulead then happily accepted this for DVD creation. I haven't burned a DVD yet because I'm not buying a burner until I can capture the footage at a workable resolution.

    It would appear that at 704x576 you will lose a few pixels of width because of the way a televsion overscans the picture: but surely you will lose no more than viewing any analogue capture with a marvel?

    I know I could add a black border or resize the video to 720x576 but this all adds time to the process and I want to convert a lot of old VHS.

    I'm surprised that no one has suggested this because it would appear to be a very workable answer to the problem of using the G400 Marvel for DVD production.

    On a different note: I am trying to squeeze 3 hours onto a single sided DVD and at the moment it looks nearly impossibe to do with decent quality: yet the BBC did it with the Hitch Hikers Guide to The Galaxy-six 30 minute episodes on one DVD.

    Yes, you can capture at 704 width to convert to DVD-MPG. However, as you are using the hardware MJPEG, I assume you are probably - sensibly - using W98SE. If so, you will certainly come up against the 4 Gb file size limitation and you should target your bitrate so that your file size is about 3.5 Gb, unless you burn in an NTFS environment (equally sensibly ).

    Yes, the quality drops at > 2hrs, because of the reduced bitrate. However, at 3 hrs and ~3300 bitrate, it is still better than VHS.

    With a DVD burner, you are limited to ~4.4 Gb. Commercial double-layer DVDs have a capacity of nearly 9 Gb, hence your BBC DVD. There is no way that we can burn such DVDs - yet (?). These have a capacity of 4 hours of good quality.

      Hi

      May I suggest using tmpgenc to encode your footage in 704X576.

      Its free from http://www.tmpgenc.net/e_main.html and its twice as fast as the Ulead encoder.

      I have tried it, its easy to use, choose whatever bitrate you like, fast and so far 100% compatable with all the DVDs I made so far.

      As regards to DVD size, yes BBC uses bigger DVDs than normal. I have space 1999. 200mins of video on a 6.3GB DVD!

        I have just found a serious flaw in my attempts to create a full DVD. While a DVD can hold over 4gb of data in order to produce the DVD an image file is first produced. This image file is at least the same size as the DVD. Unfortunatley, although a DVD will hold over 4gb of data the windows 98 fat 32 file system won't allow a file size of over 4gb to be produced. In effect: if you are using windows 98 (like I am) you are limited to a 4gb DVD.

          All the more reason to update.

            This is the point I made above. I suggest you dual boot, keeping win98se, just for capturing MJPEG, and w2k NTFS for editing and DVD burning.
