We are encoding a DV .AVI that was exported from Premiere Pro. That video file was imported into Sorenson Squeeze 4.5 to be compressed as an .FLV file. We used the on2 VP6 video codec (2pass VBR, video data rate: 464kbps, Keyframe: 180 frames, as well as cropping, contrast, and video noise reduction) and everytime the audio ran atleast 2sec faster than the video. however, when we used the Spark Pro codec (with same data settings as the on2 VP6 codec), we have no problems. where is this delay coming from?
