Encoding MPEG2-DVD from dpx image sequences produced random encoding artifacts

Apr 26, 2013 8:11 AM

I'm using PPro CS 6. I've exported my 90 minute film as a DPX sequence. This image sequence is effectively my master. I then export this DPX sequence as a MPEG2-DVD and I get the following artifacts on random frames. It happens whether I'm exporting PAL (non interlaced) or NTSC (interlaced). I've now run the encoder three separate times and I get random artifacts on completely different frames. I'm checked the DPX images and they are fine so I know this problem is happening in the encoding.

Thanks.

    I don't recall ever seeing this before.  What happens when you export an MPEG2-DVD directly from the edit, instead of the DPX?

    Well, one instance of a problem doesn't a bug make.  Let me see if I can reproduce here.

    Um...how did you get the DPX sequence back into PP for MPEG2-DVD exporting?

    choose Import, select the first image

     

    Can't.  DPX files don't show up for import (though Explorer confirms they are there).

    That's a standard supported image format for PPro. You must have some configuration issues.

    Here is another example. This time it I was encoding PAL from the DPX sequence.
