    is it a codec issue when mp4 video (from livestream) imports without audio?

    gonz456

      im a livestream member and i can download the livestreams i do there, it downloads in mp4, i just bought premier elements 10 because the specs said it could import mp4

       

      so i tried importing mp4 and i only get video?

       

      any idea why? is there something i need to do to bring the audio in as well?

       

      thankis

          Yep. That's very likely the case.

           

          There are a lot of codecs for video and audio out there, and Premiere Elements is designed primarily to interface with camcorder video.

           

          Have you opened the video in G Spot or Media Info to see which codecs it's using?

            In addition to G-Spot, MediaInfo is also a great AV file info utility. Each should give you the exact Audio CODEC in those files. It might be as easy as downloading the proper CODEC from the company that wrote it, or you might need to rip the Audio with an audio-editor, such as the great, free Audacity, Save as a PCM/WAV @ 48KHz 16-bit, and Import that, replacing the Audio Stream from the LiveStream file.

             

            Note: I find it good to have both G-Spot and MediaInfo around, as G-Spot is great with most AVI files, and does a fair job with MPEG's, MediaInfo does better with MPEG, MOV and WMV files. Knowing what is inside the AV file is very important, as MP4, WMV, AVI, etc. are just wrappers, and a lot can be inside them. This ARTICLE goes into more detail.

             

            Good luck, and once you know the CODEC of the Audio Stream, let us know, and someone can recommend where to get that CODEC.

              But how does all of this make it work with premier elements 10?

                What "all of this" does is provide DETAILS so the other users here may try to help

                 

                As Steve said (and, he very literally wrote the book!) not all files are the same... and without knowing the DETAILS of your file, there is no way for anyone to help

                 

                So... please go do what has been asked, and gather and post the DETAILS of your file

                  ive got a clean audio file to import, however, when i sync the audio

                  with the video, its synched at the beginning of the file and that

                  synchronization slowly becomes unwraveled as the file play to the point

                  where audio and video are not playing at the same time

                    Static OOS (Out Of Sync) is easy to fix. Dynamic OOS requires just a bit more work. This ARTICLE gives tips on each.

                     

                    Good luck,

                        Flash is a streaming video format for websites... an output format that is the end result of editing, not a file to be used for editing

                          not particularly stable, the file im working with speeds up and slows

                          down, a function of streaming i suppose

                          but, at times editing of these files is desired and required

                            John is right. Flash is not a codec Premiere Elements will be able to edit.

                              For editing Flash material, I would look into the Flash products from Moyea.

                               

                              With certain Flash CODEC limitations, PrPro can now edit Flash material, but that is a $700+ program. I think that you could buy one of each of the Moyea programs, and still be about $300 to the good. Before PrPro incorporated Flash Import and edit, Moyea had a great Flash plug-in, and I have used it seamlessly in PrPro 2.0. That Flash Importer, however, was never written to work in PrE. Not sure if Moyea might offer one, at some time. Though the plug-in that I have will not work in PrE, I can say that it has been excellent over the years. If they did the same for PrE, it would be great.

                               

                              Good luck,

                                You might go to the Flash forum and find out if that product is able to edit those files

                                  That is an interesting file you have! Avc-flv in an mp4. PrE does not support editing flash files. The main purpose the product is used for is to edit video from cameras. Does this file playback right on other video editors?

                                        One does not install CODEC's into an application, but to the OS.

                                         

                                        If you are lacking a necessary CODEC, I strongly recommend that you find out which one it is, and then acquire JUST that CODEC, even if it is commercial, and you pay for it. Do NOT be tempted into downloading and installing any CODEC pack.

                                          Introduction:

                                          I had a very similar issue to this importing into premiere pro (CS6):

                                           

                                          After downloading my previously recorded livestream broadcast (in which I used livestream for producers) the media would play back fine in media players. However, it would not import at all into FCP and would import with the audio and video wildly out of sync in Premiere.

                                           

                                          I Initially presumed this to be a frame drop issue due to system issues during the broadcast. After adjusting my timeline settings and re-encoding to every possible file format to no avail I came to this thread to determine if my CODECs were the issue.

                                           

                                          Resolution:

                                          In light of the above information I assumed that, perhaps, a less sophisticated program might ignore framerate or filetype based issues.

                                           

                                          • I opened the file in iMovie. The file was accepted by the import process and the audio and video was in sync.
                                          • I then exported a test iMovie project as a .mov and brought that .mov into premiere and found that everything imported properly. No sync issues, no filetype errors.

                                           

                                          I'm currently exporting the entire broadcast from iMovie and hopefully the work around holds up. I'll post an update with the result.

                                           

                                          Conclusion:

                                          It's not as technical of a solution as what's presented above and it's messy, but it is simple. Hopefully it works for your issue as well and helps anyone else with this problem.

                                           

                                          In the future I'm going to use a third party broadcasting application that allows me to store a local version in a file type of my choosing. I would suggest something similar to anyone who uses livestream procaster or livestream for producers.
