When I render my videos in imovie they're great quality, 128kbps aac, 1280hd. Lately when Youtube finishes finalizing the video, the audio/music comes out slightly scratchy, especially if the song has a bass to it. The original video on my desktop plays fine. Its just that once I upload it, Youtube does something with it. I'm getting nervous about doing voiceovers or adding music as its becoming a problem, I noticed that quality loss right away before Publishing. I thought it was just imovie, but no its definitely a Youtube issue.
I tried reuploading some videos few times but it persists. I'm using a mac desktop, firefox and safari with the latest adobe player. Anyone know what Youtube is doing to my videos?
