Hey,

I have a Sony DCR-HC90 camcorder. It is a rather new MiniDV camcorder with the ability to record two seperate 12bit 32KHz stereo tracks to the tape. In addition, it supports Sony's surroundsound microphone, ECM-HQP1, and will record the front two channels to stereo track 1, and the rear two channels to stereo track 2.

The problem is I cannot figure out how to get the surround tracks off of the camcorder. I'm not sure if both audio tracks are embedded in the single .AVI file, but if the rear channel is there then I don't know how to find it. The microphone does say that a Sony program, "Click to DVD v2.0" can extract the surroundsound tracks, however this software comes only with a Sony VAIO computer, which I do not have.

I tend to use Adobe Premiere Pro 1.5 to rip and edit my videos. Using Adobe's capture feature, I can rip exclusively the audio to a .avi file. So I could, in theory, rip the front tracks with the video to one file, and then go back and rip it all again with the rear track being saved to a seperate file. However, by doing this I end up with syncronization problems, and to be honest I can't really tell if the tracks are indeed different. My camera has settings that allow me to choose which track is outputted, however the provided instructions make it unclear whether this is applied to the video ripped to the computer or if it is merely used for playback using the camcorder's built-in speaker.

Does anyone have any ideas? Also, if it would help I could offer more explanation as to what I have tried or my set-up or whatever. Thanks for your time! :)

i have a sony camcorder from like 5 years ago that has the ability to record 2 stereo tracks @32khz or 1 16-bit stereo sound at @48khz. It didnt explain further, so i just used the 16-bit one. I'm assuming its just two audio streams in the avi file, i doubt you would have to do anything special.

Inside Adobe Primiere Pro, there is a Surcode for Dolby Digital plug in. you can use that to transcode into Dolby Surround, or Dolby Digital 5.1 if you want. To access that feature, go to File/Export/Adobe Media Encoder, then select "Surcode for Dolby Digital" from the Format list, in the audio category. Clickign advanced will give you settings. Be warned, it takes a long time to do anything in that program that isnt straight DD 2.0...
