My options for MOV audio compression

Good day everyone,
Im working with a 110mb wmv file that is just spoken word with video. Its a very simple video of a person talking without any music or fast moving images. I need a small file, help!!

My question is about the audio compression, when converting this wmv to a mov I have the following options for audio compression: 24bit format, 32bit format, alawcompression, imacompression, mace3compression, mace6compression and ulawcompression.

Since this is a rather large file I thought I would ask the advice of the forum before I spend days converting all the differant formats to see which one will give me the smallest mov file.

I found that converting the wmv to mp4 gave me a nice 45mb file but it seems that streaming an mp4 is just too time consuming or too expensive for my budget.

Please help, I need a smaller file. My current half gig mov file just wont cut it.

I will almost guarantee, your file size problem is not your audio, no matter what compression you are using. It will be from the video.

wmv is a horrible format to save any video too. You have problems with embedded DRM that is automatically added, plus incompatibility for Macintosh and Linux users.

Save your video as an mpg or mov file. I often recommend, because it is the best solution I've personally found, that any video you create, your final render should be done in Quicktime Pro, saved as an mpeg, using H.264 codec and the width/height dimensions based on your particular need for the video.

I recently created this movie, the Chapel of Yule http://services.commoncache.com/chapel_of_yule.mp4, which was originally 500mb when I exported from Adobe Premier, reduced to 12mb via Quicktime with great resolution.

One of the biggest issues with 'streaming' content, is the delivery format. Moreso when you add sound tracks, this is because the 'stream control would be via the audio track, leaving the choice to freeze the movie for the sound to be correctly timed, or have the audio breakup in bias for the movie 'stream'.

There are 3 types of 'streaming' content:
1) RSTP pure streaming (no good for audio content when part of a movie file).
2) Progressive download
3) Download and watch

Dependant on your viewers requirements, download and watch being the most predictable, progressive download requires syncronisation of both the audio and movie tracks to play fluidly, across the dynamics of the internet.

Geuis is correct in that the 'payload' of the file, would certainly be the movie content, audio normally carried much less, you should find 32bit adequate for the average headphone setup.

To assess your 'playability' of the movie, open the Info page in QT player and see what the bps rate is of the 'stream', if you acheive around 100kbps, that should play 'normally' over a T1 connection within the SL client. This is a simple math calculation of file size divided by play time of the movie, which QT reports for you. Host is correctly and you should have no problems enjoying your creations in SL, whatever the file size.
