    Re: DVD (ISO) Encoding times in AL7.2?

    Hi Scott:

    I tried the EZ capture to MPGE-2, but for some reason it only has the preset 720x480...My Panasonic DVX-100 footage is 720x486. And those 6 pixels will make the video deformed.

    Also the quality of the video is very bad in comparison to capturing AVI at 25/Mbs. I will try what you are sugesting me to see how it goes for me.

    I've read the "8 minutes to DVD" thread...It would be a dream workflow if the quality of the video wouldn't suffer so much.

    I am finishing my first AL7.2 edit to see if 7.2 improves my times over 7.1 that I had before.

    I like to render everything in the background while editing, that way my timeline is ready when I go to encode to ISO file.

    Thanks,
    Cesar Rubio.

    But all DVD's are 720 x 480. The DV-AVI codec is 720 x 480. Makes no difference what your source is if you are using this as your capture codec.

    I don't know then why my video is distorted when I capture with the EZ  tool.

    And actually is stretched not compressed...it could be that I use letterbox on my videos?

    CR.

    Video Formats/Technical Data

    NTSC

    1. Liquid Active Area 720x486; bottom field first (line 283);
    2. Uncompressed (YUV) 720x486; bottom field first (line 283);
    3. Uncompressed (2YUY) 720x512; top field first (line 7)
    4. DV 720x480; bottom field first (line 285); 4:1:1
    5. M2V (MPEG-2 @ 422P; standard; ITU 601) 720x480; top field first (line 23)
    6. M2V (MPEG-2 @ 422P;extended; ITU 601) 720x512; top field first (line 7)

     Both EZCapture and the logging tool use the same exact codecs. They can't capture different.

    Cesar,

    That one (in EZCapture) won't give you the render time improvement I'm talking about.  The "DVD compatible" codec in EZCapture isn't the same as the DVD M2V codec in the logging tool.  The DVD M2V codec I use is only available in the logging tool.  The default setting for that preset is 8Mbps/good, I think.  I made a custom capture preset set for 8.5Mbps/best.  There is also a timeline fuse/render codec for the DVD M2V codec.  There is not one for the "DVD compatible" codec.  When you put DVD M2V captured video on a timeline set the same way, your RT performance is better and maybe even rendering is sped up on your yellow slices.

    The EZCapture codec might not be very good quality.  I haven't used it in a very long time. 

    I could not see a difference capturing 25Mbps AVI vs. the codec I'm talking about.  I looked VERY closely at single frames I exported from the same material which I captured three different ways.  Your DVD is going to come out at around 8Mbps anyway.  That's how so much render time is saved.  You start with video that's closer to the final output format and rendering is much faster.
