  • Audio line out of Sync

    I am editing a project and trying to make video edits on the beat...but it seems every time I go over the last 30 seconds it keeps going out of whack with the music AFTER i have carefully lined it all up.

    I don't have ripple edit on, and I haven't touched the audio line. So I don't know what I am doing or not doing. Any clues?

    I tried clicking on "Sync" under Insert and it still lines up different almost every time i play it back. Each time! What gives.

    If you are changing the length of clips on the timeline it is best if you engage "Sync Mode" the audio clips in the audio tracks will move with your edit if not they will stay at the time code they were placed on

      I AM in Sync mode...every time i go back 10 seconds and play it back it different! And nothing has been moved.

      Will it be different if the audio line wasn't an Mp3? I have never had this problem before and it's frustrating.

        AND I did the same kinda thing last night using an Mp3 and this didn't happen, matching with the beats and all...makes no sense. That turned out perfect, but this is very annoying.

          I recommend you to avoid using mp3 files in Edius if you're doing hip-hop montage matching with beats etc.

          Convert the audio file to .wav and problem is solved. I use Audacity for that.

          I had numerous problems with mp3's just as you described. It doesn't have anything with sync/ripple modes, it's simply, let's call it, a bug.

          I don't know by what means sometimes works ok, sometimes not, I just have written in my head-
          .mp3+Edius= bad
          .wav+Edius= good

          Try it out. ;)

            Yeah that's what i was reading...

            I am going to convert the mp3 with Acid Pro and see what happens.

            Thanks for the tip!

              I don't have an answer to your problem. However, I would like to share an experience.

              I shoot video of fireworks displays that are choreographed to music. Typically, I ask the owner of the fireworks company for a copy of the music, in the form of a .wav file, to mix with my video project. Since I am mixing the original soundtrack with my video, you would think the music between my camera audio and the .wav would stay in sync. Frequently, I find it does not. I usually have to cut the .wav and slide it a frame every few minutes to keep the music in sync with my audio track.

              I've never found a reason for this.

                I had exactly the same problem as you, everything seemed to go out of random sync in an unpredictable way. The solution was to use .wav audio instead of .mp3. You'll see an immediate difference!

                  Bandman,

                  Was the problem of loosing sync due to difference in sampling rate, 44.1KHz for CD and 48kHz for audio?

                    That's an interesting thought. My system is down at the moment awaiting a new video card and my copy of Edius 5. When I get everything back together, I'll convert the .wav into a 48KHz file before importing it into Edius. I'll report back later.

                      Thats correct - any audio file in the time line at 44K will lose sync and drift when played from the top... I convert everything to 48K and sync is fine on any length project.

                        Well i used Acid Pro 6 to convert the Mp3 in question to WAV and it did the trick.

                        Thanks everyone for your help. One more problem solved.
