I use portable audio recorder and I sync the audio in post. I edit my videos in Vegas and my timeline is set correctly. No matter what template I pick or format I render to (.avi .m2t .mp4 etc.) the video comes out fine. Every time, I try to convert the same video to .flv using AVS Video Converter 8.1 (Audio Codec MPEG-2/4 or MP3 with Sample Rate: 44100Hz and Bit Rate from 192 or 320 Size: 16bit) I get video and audio out of sync. I even tried adding a white noise and going that route without much success. Anyone experienced have a solution for this?
Thank you in advance!

Baldrick Thank you very much!
I just ran few short tests on converting mp4 into a .flv container with both apps you had suggested to me and Voila! It works!
I just do not understand why other application make the video and audio out of sync. The only free app the had worked for me before these two was SUPER but with very limited way of controlling the flash video's bit rate.
I also noticed that there is a audio delay relative to video in a converted flash video (it plays as it supposed to, meaning everything is in sync).
