  1. I accept fully the fact they I need to set to square pixels .. that is going to be next step.
    Do I just ignore this 5:4 information.
    Resize as mentioned to 960x720

    That was going to be the next step .. just seeing 5:4 when I had not set for any change the me.

    Thanks for explaining.

    Yes. That is the FAR not the DAR.

    Yes. Then FAR = DAR

    with square pixels SAR = 1:1

    Code:
    DAR = FAR * SAR
    DAR = 960:720 * 1:1
    DAR = 960/720 * 1/1
    DAR = 960/720
    DAR = 1.777... = 16/9 = 16:9
    Actually, most PAL analog video capture with a 720x576 frame holds the 4:3 DAR image in a ~702x576 portion of the frame (the rest is padding). So for more perfect AR scaling you should crop the frame down to 702x576 and then resize to a 16:9 frame size. But the ~2 percent error usually isn't worth worrying about.

  3. Thanks for the education.

    MediaInfo show the DAR as 5:4 (attached) ... appreciate you have the experience to know this is FAR not DAR
    Is there a alternative to MediaInfo that I would be better to use for this ?

    No program can know what the DAR is unless it's flagged. MediaInfo, like most other programs, defaults to DAR = FAR (ie, they assume square pixels, SAR = 1:1) in the absence of DAR or SAR flags.
