    Hey everyone

    Anyone know why my quicktime file when being compressed to an flv in Sorenson 4.5 would be going out of sync? the quicktime file has the animation codec holding an alpha channel. I’m wondering if that codec is a result of it going out of sync when being compressed. I’m using the on2vp6 with alpha channel. thanks

    I just used on2flix pro and it kept everything in sync. Sorenson in my experience has an issue with the animation codec keeping audio in sync with picture. Flix pro did the job and now i’m back on track. thanks

    Bobby – I had the exact opposite experience. Curious – are you on windows or mac?

    I think it is a Sorenson issue with the ON2VP6 codec. I tried to encode some DV AVI files into flash video files using Sorenson 4.5 and the ON2 VP6 codec and halfway through the 30 second videos the video was out of sync with the audio.

    Using Adobe Flash Encoder it worked perfectly though from the same source files.
