I am transcoding documentary footage. The camera and boom sound together are 16 bit and 48 Khz.
When i synch them together, the audio matches for a minute or so, and then slowly, the boom audio falls behind and a couple of seconds later there is an echo. I have to re synch this hour long clip (no slates of any kind or markers) and re-synch it at every minute mark.
The earlier boom audio was recorded at 41 khz and the camera at 48. I converted the boom to 48khz and that worked for two or three clips, but not the rest.
I am sure I am missing something, or, there is an easier way to do this. Does anybody else ever have this problem? What am i missing? Some advice will be helpful, please.
