    Hello All

    I've tested Auto Gordian Knot (AGK) and Clone DVD Mobile on the same 1:41 minute file.
    AGK takes 5 hours 24 minutes
    CloneDVD Mobile takes 1 hour 54 minutes

    I cannot see a difference between the quality of the two avi files. Are there any settings I can make to get AGK closer to the CloneDVD Mobile processing time?

    Any ideas on this would be appreciated.


    Here are some specs and settings:

    PC Specs
    OS: Windows XP Home, Service Pack 3
    Direct X: 9.0c
    Processor: Pentium 4, 2400 MHz

    See if changing the AGK Quality setting to match CloneDVD makes a difference - I haven't used CloneDVD.

    These kind of questions always confuse me.
    Then just use CloneDVD Mobile and be done with it.

    AGK quality setting range is 10 to 100
    CloneDVD Mobile quality setting range is 10 to 166 - so a setting in one does not necessarily match the other.

    I set the quality settings of the two programs so that each would produce an avi of approximately the same size (that's why the two quality setting numbers do not match. Is it incorrect to assume similar size avi's have the same amount of compression? That's why I assume the quality appears to me similar between the two files.

    So if the original files start out the same, and are compressed to approximately the same degree by both programs, is there a reason why one program takes so much longer to do the compression than the other.

    If I am making incorrect assumptions here re: the compression of the files, please set me straight.

    AGK, if you set the output size, it does two passes to ensure the target is reached.
    If you set 'Target Quality' it does one pass - and is certainly faster.
    But as to comparing the two programs - I have nothing to offer.
