doom9,
After solving several issues by reading the great posts here, I have my first question.
Question: With two separate sources for video and audio with no precedent for sync, is there a better way than "eyeballing" the mux?
Because of a unique arrangement, we're capturing video and audio from two separate instruments. The resulting encodes are from Windows Media Encoder (wmv/wma) but are usually between 0.5 and 2.0 seconds apart in total length. Cutting the files to equal lengths and adding or subtracting silence from the audio isn't a problem with the tools I have.
Until now, I've been combining the tracks and playing them in Media Player Classic. I'll play with the audio delay (ms) until it "looks right" and then use the figure to reconfigure the cutting tools.
After hitting a dead end with Adobe Premiere, I'm hoping there's some other tool out there that will help me view a combined A/V stream frame by frame while looking at a spectrum of the audio output. Really, any suggestions on getting a more precise sync than playing it by ear/eye.
Again, formats or codecs aren't an issue and because of internal equipment delays, these captures will never be in sync naturally. An adhoc delay +/- will always have to be added in my situation. I'm just after some recommendations on getting it as correct as possible.
Thanks!
