    Jerky Playback

    dee1nepistle Community Member

      Hello everyone. I have Sony NX5 AVCHD Cameras.

      There is no problem whatsoever with editing the files created by the Camera.

      I don't worry about picking the wrong sequence because Premiere automatically checks that and I follow its recommendations.

      The Rec for mat I pick for the Camera is 1080/50i FH, 576/50i HQ.

       

      After editing is done and I need to playback to a tape, the output and recorded material has this jerky feel to it.

      The video does not play in reel-time but the audio does.

       

      I have changed my connection device setting severally in device manager but none is fixing the issue.

       

      Changed my deck settings severally as well but didn't solve it either.

       

      I tried to playback without going through the export to tape option (manually hitting the rec button on my capture device) but still not fixed.

       

      I need this to be fixed as I am into broadcasting, and I can't afford to downsize my video to mpeg 2 DVD just because I can't export to tape.

       

      I appreciate all the help I can get. Thanks

          "The Rec for mat I pick for the Camera is 1080/50i FH, 576/50i HQ."

           

          Which format is your material and sequence,  You have given both a HD and SD format.

            I don't understand what you mean by I have given both a HD and SD format.
            My material is 1080/50i FH, 576/50i HQ.

            My Sequence is  AVCHD 1080i Square Pixels

              1080.50i is high definition, 576 50i is standard definition which are you using?

                Which one do I use where?
                Going by my Camera setting, I use high def.

                  When you first render de sequence is the playback still jerky?

                  Otherwhise you could transcode it to hdv. When you have done this import it in premiere and put it on tape.

                   

                  You could also transcode it to mp4 / h264. The file is much smaller and in some cases you could save it to a single dvd for archive.

                    When I render and playback, it's still jerky and my texts lose quality but my exported material looks alright.

                    I am very familiar with h.264.

                    I am beginning to think my deck is downsizing the quality.

                    I have Sony M15. I have checked the deck settings and the downsize is off.

                    I have also exported (transcoded) my material from hd to dv. Brought it to a dv timeline and still the same.

                    Lastly, I am beginning to think my deck is totally responsible.

                    While I'm yet to launch the editing software, the display monitor is already having the jerky feel as I could observe with the desk's info on the monitor.

                    When I set my deck to hdv, I can't receive preview on the monitor until I'm ready to export to tape.

                     

                    Frustrating!

                      But why do you want to set it back to tape?

                      Is it not better to archive all on a disk? or make a file and archive it on a harddisk?

                        My archived material remains on my Hard Disk.

                        I export to tape for Broadcast.

                        My TV Station accepts tapes and DVD only.

                         

                        If I use DVD, my HD material automatically goes back to SD (720x576)

                        Camera work and Post-Pro efforts wasted.

                         

                        See why now?

                          How long is the item you broadcast?

                          Because when you make a file out of it in mpeg2 or mpeg4 you can hold the HD quality even if it is a dvd.

                           

                          What settings are you using to make it a mpeg file?

                            Broadcast is 50mins long

                            When going on DVD, MPEG2-DVD (m2v)

                              When you choose h,264 and set te target bitrate to 12 even as the max bitrate you have a file that is 1440-1080 and the file is 4360 mb in size.

                               

                              When you have the pay version of retransfer you could even sent it by internet to your tv station.

                                Thanks but that's not a route that solves my problem.

                                If I must burn the material to a DVD, it will still be compressed to SD whether I like it or not by the authoring software.

                                Sending the file via a third party has to be an option provided by the TV Station.

                                But since I don't have that option from them, I can't use it.

                                Thanks for your help anyways.

                                Cheers!

                                  But you don't have to author the dvd.

                                   

                                  When your project is finished you go to export. There you select the setting h264 and set the target bitrate for both to 12.

                                  You can set it in a render que or export it directly to a map.

                                   

                                  Then you burn your file onto a dvd.

                                   

                                  What you do is making a dvd. Then your frame size is SD.

                                   

                                  I have made a test rendering for 50 min. and the file was just 4,57 gb

                                  and it was still 1440 by 1080.

                                   

                                  When your tv station has an ftp server you can directly send it to there. So you don't have to take a third party to send it?

                                   

                                  Anyway succes

                                    Thanks buddy I have learnt one from you.

                                    My DVD quality is better if I follow your style.

                                    But it there's a little disadvantage when I need to use menus, chapters and Intro Videos in Encore.

                                    The size of the main feature would have eaten up the entire DVD.

                                    Thanks anyways, that one thing gained if I won't be adding stuff to the DVD.

                                     

                                    Moving forward, I set my Deck to HDV

                                    Sent Component out to my TV monitor and guess what,

                                    Both the Preview on TV Monitor and Recorded Material on the tape look better than what I have on my screen (lol)

                                    I see that my deck is doing some serious downsizing when set to auto.
