glitches

Jan 29, 2013 9:04 AM

Please help me diagnose a problem.

 

I'm in the process of finishing a DVD. I've made two DVDs already that didn't pass my QA for various reasons. The third disc I thought would be a release candidate. But on playing the disc, I found a couple of interesting glitches.

 

The first one is a single frame wrong. It looks like it was taken from the video stream 10 or 12 frames away. It really stood out; what I saw in real-time was just a flash of something being wrong (a big continuity break). When I went back and single-framed my way through the video, it was easy to see. It's a full frame, fully formed, but it's in the wrong place.

 

The second glitch comes a few minutes later. It takes the form of several stutters. When I single-frame my way through the video, I can see that in several places frames repeat.

 

Sound isn't effected with either glitch. Hmmm.... And isn't sound recorded separately on DVDs?

 

This morning I went back to PPro to find these problems in the source. Except... these problems aren't in the source. The source is fine. When I single-frame my way through, there are no glitches to be found in either place. And both are in the middle of clips, not at a cut.

 

So what's the cause? Bad encode from AME? Bad physical DVD? These are Verbatim DVD-Rs, 16x, part of a 50 count cake box. How does one diagnose a problem like this?

    Try it with a disk burned half the speed.

    Dynamic Link to Encore or exported assets out of PP?

    1st, try exporting MPEG2 DVD from PPro instead of Dynamic Link... which sometimes has problems

    2nd, create an ISO out of Encore and use Imgburn to write the actual disc... at the SLOWEST burn speed possible

    Create an ISO (Encore) or folder on your hard drive (Encore or Premiere Elements) and then use the FREE http://www.imgburn.com/index.php?act=download to write files or folders or ISO to disc for DVD or BluRay (send the author a PayPal donation if you like his program)

    .

    Imgburn will read the ACTUAL disc brand from the disc, which is not always the same as the box label (Memorex is notorious for buying "anything" and putting it inside a Memorex box)

    .

    When you write to disc with Imgburn, use the SLOWEST possible speed setting, so your burner has the best chance to create "good, well formed" laser burn holes... since no DVD player is required to read a burned disc, having a "good" one from a high quality blank will help

    .

    Use Taiyo Yuden single layer or Verbatim Two layer Or Falcon Pro for inkjet printable Two layer

    I'm using exactly the same export settings:

     

    Unlikely.  Premiere Pro, AME and Encore all use the same encoding engine, so something is different.  (The usual suspect is Max Render Quality, which adds significantly to render times.)

    This may help... or may not, if you are already scaling your pictures

    What Encore version (re updates)?

     

    There have been reports of "random frames," and I don't recall a single situation or fix. I recall something that was fixed by an update, but I don't think this was it. I did not find the threads I was looking for using "random frame" searching this forum. I'd try some other variations and use google.

     

    Did not read all the above in detail: the photoshop pix are in Premiere? Or inserted on Encore timelines?

    Very odd.

     

    Since you have nothing better to do (ha, ha!), I'd see if you can reproduce this in a very short version that one of us could test. But it sounds too unpredictable.

     

    You might file a bug report even if you can't precisely replicate it. No matter what you have done, it shouldn't do this!
