Hello I'm totally new at this, and need some recommendation. As a test, I shot a conference with a camcorder that saved the file as .MOV (MPEG-PS = MPEG 224 + AC-3) and also recorded the sound with an independent digital recorder that saved the file as WAV. So I need to remove the soundtrack from the MOV file, insert the WAV, and try to sync both. Someone recommended Sony's Movie Studio HD for this, but when I load the file, it complains that no codec is available. This is on a brand new Windows7 laptop, so that makes sense (although I would have expected Sony to install codecs for something as common as MPGE(2), though). Someone else recommended that I install QuickTime, but before I go ahead, could someone tell me what reputable codec packs I should install for editing video? K-Lite? CCCP? Other? Thank you.
