    audio issue with files recorded in JVC HM100 (mp4)

    dvgroup

      I am trying from some time to try all the compressions and formats in Adobe Premiere 4 with the recorded files from JVC GY-HM-100E camcorder.

      the video is Ok in all of them, but the problem is with audio.

      in the same clip when playing in timeline, there are blocks of audio played properly and than in the middle of those there are blocks where there is only noise. if playing the clips in the camera, or in other players the audio is ok, and there is no problem.

      we have tried also to change in different configurations/compression recording in the camcorder, but the result is always the same. another college of us has the same type of problem.

       

      can anyone help on this, or we should change the system and switch to some other editing solutions?

          Work through all of the steps (ideas) listed at http://ppro.wikia.com/wiki/Troubleshooting


          If your problem isn't fixed after you follow all of the steps, report back with the DETAILS asked for in the FINALLY section, the questions at the end of the troubleshooting link... most especially the codec used... see Question 1

           

          My GUESS is that you have a mis-match between your project settings and the video... see above about details

            this is not the answer I was expected to get.

            anyway, I got many other ideas and answers from many other guys whom had the same problem as we do.

            and the best solution for the moment is to get the small utility from Sony XDCAM EX Media Browser whom check the files in the card and than you can export them in MXF for NLE

            than just import those files into the XDCAM EX preset in Adobe and everything is fine with the video/audio

             

            normally this is a problem in Adobe whom should have fixed it many months ago, but still in the last update 4.2.1 this isnt fixed.

             

            anyway, important until them to fix that is that this small utility can help anyone.

            the export through this is 1:10 - 10 min exported in less than a minute.

             

            this information will be very usefull also for JVC whom it looks like they dont have the idea how this problem in adobe can be handel.

            regard the information of how to setup a PC/Workstation.

             

            this is our business which we are doing in more than 10 years.

              You ask Adobe to fix something for you, but...I would suggest as professionals , you  guys did not do your homework and choose a camera that recorded in a format entirely suitable for PPRO.  (ie you need to transcode your media)

               

              You created a slightly cumbersome workflow for your selves.

               

              Alternatively your homework would have told you that FCP may have been a better "editor" for that material.

               

              I am not pinging you guys but so often this forum has posts from users who are suddenly surprised that they are having difficulty "editing" their footage after making an "unfortunate choice" at some stage in their hardware / software purchase.

                this depend how much information you have for JVC GY-HM100

                 

                this camera is a dual recording format\compression

                 

                mov for editing in FCP, or mp4 for editing in adobe, avid, canopus, ect

                 

                as far as I got one information coming from NAB 2010, adobe knows this issue for which they have the plan to fix it in adobe CS4, but not in CS4.

                 

                it is nice everyone whom have invested in money in CS4 to know that they have to throw this product, since it will not be fixed from adobe.

                 

                there is the other option to handle the issue with the audio : explore the SDHC card using XDCAM EX Media browser and export them as MXF for NLE, than import them in the premiere and everything is working fine.

                 

                by the other side - regarding FCP. yes, we could try it, if apple should agree to create 2 separate distribution channels :

                 

                one for the business products, and one for the consumer.

                 

                by us here, there is only one retailer (even this is not official) whom is selling iPod and iPhones. of course, this is also the most interesting and money making products for apple.

                 

                so, the best choice for us and our clients remains in Adobe.

                 

                Canopus - no one knows how the situation will go with Grass Valley (probably they will split divisions and be sold during 2010/2011

                 

                Avid - the same situation. in december they were in discussion to be sold, but the buyer didn't accept to keep all the people working there. but something will happen in 2010.

                so.....
