    PRE 9 drops frames when creating mpeg for ntsc dvd

    dennisbthomas Level 1

      Project Setting:

           AVCHD HD 1080i 30 5.1 channel

      Camera

          Sony HDR-CX550V

      Computer

           Intel i3-540 4 GB Windows x64 with latest updates

           Video Card Nvidia GeForce GTS450

       

      Process

       

      1.Create a test project, 2 clips, then Share/Computer/MPEG/NTSC Standard or Widescreen

      2.Transfer the .mpg file to a Tivo 2.

      3. View the clip on the TV and there are occasional dropped frames.

      Notes:

      1. This worked ok with version 8.0.1

      2. Plays ok on Windows Media Player.

      3. Still have Version 8.01 installed and it works ok with it.

       

      Any comments or suggestions are appreciated.

       

      Thanks

          It can't be dropped frames you're seeing, since those could only occur if you were capturing your video as a stream.

           

          With AVCHD video, on the other hand, you download the video with the Video Importer. It loads from your camcorder to your computer as a single file -- not individual frames.

           

          This camcorder records in both standard def and hi-def. I'm assuming you're shooting in hi-def and that you're setting up your project with the 1920x1080 5.1 audio project preset. And, of course, that you're using the Premiere Elements Video Importer and that you're not using another piece of software to capture the video as a stream.

           

          Anyway, you say the output file plays okay in Windows Media Player. This would indicate that there are no dropped frames -- so Premiere Elements is doing its job. The problem must be in your Tivo or its interface.

           

          How are you getting this MPEG into your Tivo, by the way?

           

          Are you sure that the MPEG with the preset youv'e chosen is the ideal format for playing on a Tivo (Share/Computer/MPEG/NTSC Standard or Widescreen)? Where did you find these specs? I've not been able to find specs for creating video for Tivo.

            Hi Steve,

             

            I have been using the software from SONY to download from the camera to the computer.

            Also, I'm shooting in 1440x1080 rather than 1920x1080, since I only have an I3 but looking for an I7 later this year.

             

            I used Tivo Desktop 2.8.1. I drop the mpg file into a Tivo directly then I can see it from the TV and have it transfer to the Tivo. This is how I've been testing projects since PRE 8, Really easy and realtively fast.

             

            The TIvo desktop will only take a .mpg file but not an .m2t.

             

            What I don't understand is how the V8 file works correctly but the V9 file doesn't.

             

            Thanks for your help

            Dennis

              I'm not sure how you're getting 1440x1080 video out of that camcorder when the Sony site says the video is 1920x1080.

               

              I would also not recommend using the Sony software to capture your camcorder's footage. It may be contributing to your problems. You should create a project in Premiere Elements that matches your camcorder's specs, connect your camcorder via USB and then use Premiere Elements' Get Media/AVCHD camcorder to open the Video Importer and import your footage from the camcorder to your computer and into your project.

               

              And I STILL don't know how you're getting your video from your computer to your Tivo -- but that may be because I don't know enough about Tivos. Is it connected to your computer and you just move the file from one hard drive to another?

               

              Finally, can you show me where you got the information on what type of video file your Tivo will play? It's pretty unlikely to be a DV/MPEG and, as I said above, I can't find any information online that specifies what the Tivo does play.

                Hi Steve,

                I lost about an hour of info that I was sending you in regards to your last email questions.

                Can we do this in parts, I'll send you some info and then in a later email answer your questions.

                THanks

                 

                I used a small clip that I uploaded from the SonyCX550V a few months ago. I then created a V8 project and a V9 project; using the same clip, and only clip. I used the same project settings: NTSC-AVCHD-HD- 1080 30 5.1 channel.

                For each project I created a Share/Computer/MPEG NTSC/DVD.

                 

                The V8 mpeg is 538654 bytes longer than the V9 mpeg. Tranfserred both to the Tivo-2 and the V8 plays great as they always have but the V9 dropped frames, at least that what it appears to me.

                 

                I then did a mediainfo on each file and have enclosed the results below.

                Please let me know if you have any questions and I will answer your above questions later this afternoon.

                As always, Thanks for your help Steve!

                  You say "I used a small clip that I uploaded from the SonyCX550V".

                   

                  Is this video that was downloaded from your camcorder using the Premiere Elements Video Importer?

                   

                  As I've said, you can't use the Sony software to get the video because it may use a different system that may be resulting in your 'dropped frames'.

                    Yes the small clip was download from the SONY using the SONY downloader program.

                     

                    Do you think I could put that clip back on the  SONY camera and then download using pre9? And get the results are looking for.

                      I don't know if the Sony program changed the file in any way. If it did, then putting back into the camcorder won't undo this damage.

                       

                      If you'd like to try an experiment with a fresh clip you've shot on your camcorder, we can try to run it through Premiere Elements from scratch and see if the results are any better.

                       

                      This is a good way to troubleshoot this problem. Just taking it one step at a time and avoiding any variables.

                        Good idea.

                        Whne I get back from the store this pm I'll try it both ways and see what I get.

                        Thanks

                          Steve,

                          I think the problem is in the interface between the Tivo Program that runs on the computer and the Tivo-2, or at least it only has failed using the Tivo-2.

                           

                          I created a new clip on the Sony and used PRE 9 to upload it to the computer. I think created an .mpg file and transfered it to the Tivo. Same problem as with the older clip.

                          I then did the same process using PRE 8 and it worked ok.

                           

                          I think created a DVD using the new uploaded clip and it worked. So at least the problem has only showed up using the TIvo.

                           

                          Also I had the use the FLIP, AVCHD, Cameras and Phones option to capture the file from the Sony as the DVD Camcorder or PC DVD Drive option wouldn't recognize the Sony Camera. I think that's correct isn't it?

                           

                          I'm going to investigate the Tivo issue further tomorrow.

                           

                          Thanks for your help!

                            I have no experience going TO a Tivo, but have seen many posts regarding going FROM a Tivo. Seems that there are some proprietary aspects of Tivo.

                             

                            Good luck,

                              I agree, Bill. This is why I've asked the poster where he's getting the specs for the files he's creating for Tivo. I've found some contradictory information online.

                               

                              Getting back to the poster though -- I don't know why the program isn't seeing your camcorder. This shouldn't happen.

                               

                              Are you sure your camcorder is turned on (to VTR) and properly connected to your computer? Can you browse to the camcorder using your computer's operating system?

                                Steve,

                                This is the web page for Tivo Desktop Plus that show's the formats that it will accept for sending video clips from the computer to Tivo. Getting Video clips from Tivo to the Computer in a useable manner is requires other software to convert from .tivo to .mpg.

                                Extract from page:

                                Supported video formats include:

                                The FLIP, AVCHD, Cameras and Phones was the only option that recognized my camera and it worked perfectly.

                                Hope I didn't imply that none of the options worked.

                                 

                                I couldn't find any Tivo related problems so I'm going to post a problem to their site.

                                It does seem strange that Pre 8 and Pre 9 create a different sized .mpg file for the same identical project.

                                Thanks for all of your help!
