If your audio is not synced with video, I can offer cheap and high quality solution. You will send me the video file and I will then separate audio and video using professional software and then "align" the audio to match the scene. It would be great if you could send me the file for a preview so we could avoid any misunderstanding. Do not hesitate to contact me, I will gladly answer all your questions! Thanks and hope hearing from you! If your file has DRIFTING ISSUE (drifting issue - It starts out perfect/flawless but drifts/gets more out of sync the longer the stream runs) the price is higher - please ask me for a custom offer. Thanks!
