    Disc encoding problems?

    Tim Flippance Level 1

      Two separate problems:

       

      1/  I downscaled a short PAL 50i widescreen HDV video from CS4 to MPEG-2 DVD using "Use Maximum Render Quality" in Export Settings. The audio was PCM. I used VBR 2 Pass, Min bitrate 2.8, Max bitrate 8, Target bitrate 7, M frames 3, N frames 12, as in Jeff Bellunes tutorial. I burned it with ImgBurn. The disc plays perfectly in my DVD player, but won't play at all in two of my friends players, and plays without audio in a third player. Why is my DVD not compatible with all players?

       

      2/  I transcoded a PAL 50i HDV  project to MPEG-2 Blu-Ray image, then burned it to Blu-Ray disc using ImgBurn. The disc plays OK for a few minutes, then suddenly at a transition point, the sound goes completely out of sync with the picture, and remains so. The project plays perfectly in Pro with no loss of sync.

       

      If anyone has any ideas for these 2 problems I would be grateful to hear them.  Thanks

          Did you use Verbatim or Taio Yuden disks?

            Number 1 is almost certainly a result of poor quality blank media or too

            fast a burn speed.  It could also be a burner firmware issue.

             

            Number 2 may also result from poor quality blank media.  You can

            troubleshoot a media issue if you have software like VirtualCloneDrive

            from Slysoft.  You can mount the image file and have Windows see it as a

            new BD/DVD drive.  Then a software DVD player can play the image file

            just as if it was playing a burned disc.  If the software player plays

            the image properly, then blank media issues become even more likely.

              The DVD was TDK

               

              I don't know what the BR disc was but it was blank white

                Thanks

                 

                What is burner firmware?

                 

                VirtualCloneDrive sounds useful. Is it free?

                  Tim,

                   

                  Once, TDK had good media. Now, they seem to have followed the Memorex business model of buying from the cheapest source and then rebranding these. Use ImgBurn to look at several of your discs. I'll bet that in a spindle of 25 you have at least two mfgrs., and none will be TDK.

                   

                  As has been stated, Verbatim, or Taiyo Yuden are some of the last good discs, with but a few exceptions.

                   

                  Good luck,

                    What is burner firmware?

                     

                    Tim,

                     

                    Many pieces of electronic equipment have a chip with an instruction set encoded to it. This encoded instruction set is the "Firmware." With many of these devices, one can "flash" that chip to update that instruction set. Sometimes, this is to correct errors, and sometimes to implement new features.

                     

                    In the case of a few pieces of hardware, this will remove the ability to, say burned BD discs. It seems that some of the BD players and things like Playstations have been crippled by firmware updades. You do not have to worry about that in your case.

                     

                    Good luck,

                      all my TDK discs seem to be MB01RG40,  is that a "bad" brand?

                        what you say about burner firmware is interesting, and may also explain another long-term problem I've had: my film which contains a lot of slow pan shots across trees with leaves waving in the wind gave me a lot of problems with overloading the codec causing flickery movement and, when played on BR player, brightness flickering in the detailed areas of the picture. I assumed this brightness flickering was an inevitable part of the Blu-Ray encoding process, but when I copied the film back from the BR disc into the computer it plays perfectly with no brightness flickering. Therefore the flickering is not on the disc but is caused by my BR player (which was very expensive so it shouldn't be faulty). So my question is, is there likely to be a firmware update available for my BR player which will fix this problem?   YAMAHA BD-D2900

                              I tried 1x write speed for the DVD but no use. At least I set it to 1x in ImgBurn, but it burned a bit fast so I'm not convinced.

                               

                              Another thought has occured to me: when I downscaled I didn't type in 8 for max bitrate, I moved the slider giving something like 8.01

                               

                              When I set "Use Maximum Render Quality" it already had "Include Source XMP Metadata" set, so I left it set.

                               

                              Would these 2 things have affected it?

                                  This is difficult footage, at best. Two things can contribute to getting the best Transcode with difficult footage: the CODEC used, and the bit-rate of that footage.

                                   

                                  Some people report that the H.264 CODEC does a better job for their footage, while others tout the HD MPEG-2 CODEC. I'd pick up a few BD RE discs, and test some of the worst of this footage, that which looks worst on BD, using both CODEC's and also adjusting the bit-rate up. When the bit-rate goes up, the Duration of the movie on BD will go down, so there is a trade-off - quality vs Duration.

                                   

                                  I'd be very interested in hearing what works best for you.

                                   

                                  For this issue, I do not think that a firmware update is likely to help, but I could well be wrong there too.

                                   

                                  Good luck,

                                                That's a pity. I was hoping the player was intended for 24p, but they might have an update to make it play 50i better.

                                                 

                                                For the record H.264 was far worse than MPEG-2

                                                 

                                                I used 40 mbps and also lower bitrates - no difference

                                                 

                                                The point is it can't (it seems to me) be the codec as such because when I copied it off the BR disc into the computer it played perfectly in the computer. Its only on the BR player that the brightness flickers.

I've opened a case with Adobe C/S in hopes to settle this on a permanent basis, plus get all that registration info back.

                                                  Thanks,

                                                    Tim,

                                                     

                                                    For the record H.264 was far worse than MPEG-2

                                                     

                                                    I used 40 mbps and also lower bitrates - no difference


                                                    Thanks for reporting. Maybe someone else can help get better results from that problem footage. Those were the only two things that I could think of. Others will surely have some more suggestions.

                                                     

                                                    Good luck,

                                                      I downloaded VirtualCloneDrive but I can't get it to work - it seems to have no instructions

                                                        Did you install it yet?  What happens when you launch the program after

                                                        installing?

                                                          I click on the icon and I get a little window with 5 things you can tick : Virtual sheep, etc

                                                            The only setting I have checked is "Keep history of recently mounted

                                                            images".  You select the number of virtual drives that you want to have

                                                            available by using the drop-down list.  They will show up in Windows

                                                            Explorer.

                                                             

                                                            I don't think I've ever even looked at the Language and Info tabs.
