Can anyone recommend any software which would allow me to:
(1) Fix unsychronized video and audio throughout a movie (when spoken words do not correspond with mouth movements).
(2) "Level" the sound volume throughout a movie (to avoid loud music that blasts me off the couch).
(3) Increase the voice volume, and reduce the music volume (so music does not drown out the speech).
I want to make these "edits" to full length movies which I have copied onto my HDD from my purchased DVDs (mostly "MP4" and "AVI"). So far, I have only Standard Definition movies on my HDD, but I plan to copy my Blu-ray discs in the future.
I use a PC with a Core i7-950 CPU, 6GB of RAM memory, a 128GB SSD for my Windows 7 Home Premium 64-bit OS and programs, and 2TB HDDs for data and backups. My video card is only a ASUS GeForce ENGTS450.
