    Encore adds random static (Popping and Crackling) to audio from AVI files

    Kopy-Rite Community Member

      We spend the whole day today trying to debug this problem... any help would be greatly appreciated.

       

      We have a large conversion project where we are capturing VHS videos and converting them to DVD.

       

      For those that require chapters, we are using Encore CS4.

       

      All of the videos were captured the same way, in an AVI format.

       

      We have found that when we load them into an Encore CS4 timeline, we will hear random static sounds -- pops in the audio.

       

      We believe the AVI file is clean.  We can watch the video in Windows Media Player, and the audio is fine.  We can burn the AVI file to a DVD video using another low-end package (Power Director) and the DVD is fine.  The AVI files have been run on other systems, and the audio crackling sound does not present itself.

       

      But when we try to use Encore, some of the files exhibit the crackling sound.  (Note that not all of the files have this problem.  But those that do exhibit the problems will exhibit them every time.)

       

      We tried loading them into Premier -- same thing.

       

      So, this problem seems to be limited to Adobe tools.

       

      We are running Windows 7 on an Intel i7, ATI Radeon card... a really fast, strong, stable system.

       

      At this point we're not sure what to try...

       

      We have attempted to pre-encode them using Adobe Media Encoder.  Same results, regardless of which audio settings we try.

       

      Any suggestions?

       

      Thanks!

          If your codec is anything other than DV AVI type 2 with 16bit 48khz sound, it is not suitable for Premiere or Encore

            Well, this gives me something to explore.  Thank you.

             

            It looks like it meets the requirements you identified, but I cannot tell the "type 2"

              It's interesting that the Audio does not show in G-Spot.

               

              DV-AVI Type I files (not what PrPro will Capture, but what Windows Movie Maker will), often have Audio sync issues.

               

              Good luck,
