Defects when burning CS4 MPEG-2 to Blu-Ray

Feb 27, 2012 7:47 AM

I made a 1440 x 1080 video which contains some effects such as:   one single frame repeated many times to give a still,  a short sequence (about 10 frames) repeated in reverse, then forward, then reverse, etc to give a movement going to and fro.  This plays fine in the Pro timeline, and also in an MPEG-2 exported file, but when I burn it to Blu-Ray in MPEG-2, and play the disc, these effects play in a very inferior fashion, ( the "still" is very low definition, the movement is very jerky) though the rest of the video plays OK.   What is going on?  The Blu-Ray player is SAMSUNG BD-D5500 and is specified as being able to play MPEG-2.

    When I play the disc on the computer it plays perfectly for the motion effects parts,  though the definition of the "still" is still bad.  Actualy I was wrong when I said the definition of the still was fine on the MPEG-2 file version. It isn't.

     

    So to summarise:

     

    In the Pro timeline, both the "still" and the reverse motion bits play perfectly.

    In the MPEG-2 file the "still" is bad definition, but the reverse motion bits are fine.

    Ditto above when the BR disc is played on the computer.

    When the BR disc is played on the SAMSUNG player the still is low definition, and the reverse motion is jerky.

    Change the single frame to a still and make that into 10 frames.

    When reversing a clip set it to Always deinterlace in the Field Options

    Try that and see how that looks.

    Unfortunately I can't do any of that because I've deleted the original Pro project.  But thanks for the advice on the still and the reverse clip.  But why does a disc which plays perfectly well on the PC, develope all these faults when played on a stand-alone Blu-Ray player?

    The disk might not be fully compatible with the player, or the player with the disk. Depends on how you look at it.

    But why isn't it compatible with the player?  Can anyone recommend a BR player which is KNOWN to play home-burned MPEG-2 discs without error?   Note, the jittery reverse motion is not the only fault I get, also I get brightness flickering in the detailed areas of pan shots across moving foliage, and this flickering is NOT present when the disc is played in the computer.

    We had these same problems when DVD was just on the market.

    We changed brand or lowered the bitrate or lowered the burning speed.

    If that did not help the player went out the door and bought another brand. Lots of trial and error.

    I have an el cheapo BD player and use Verbatim disks and even the BD-RE's play fine.
