I need to compress a file for broadcast and get it under 2 gigs. The target bit rate I need is 4.4 mbps. Under the "Quality" tab in the Encoder inspector, I'm unable to choose a bit rate lower than 10 mbps. Any suggestions? Thanks for any help.
Compressor, OS X Mountain Lion (10.8.2)
DId they specify MPEG?
Yes, the televison station I'm sending the file to requires MPEG-2.
It may (probably will) look like garbage at that low of a bit rate.
If you follow David Brewer's advice and use the DVD preset you will also need to mux the audio in MPEG Streamclip. Compressor's DVD preset assumes you're going to an authoring program with the out put and gives you elementary streams. You need to use both the audio and video elementary stream presets in the Disc Burning folder in your target. Output them to a destination folder. Make sure the mv and AC3 files have the identical names before the extension. Drag the video file into STreamclip and the audio should accompany it as well. Save as MPEG with MP2 audio and the extension will change to MPEG.
I assume it's an SD file. If so, you might be OK with the quality; but it's a very low rate for broadcast.
Good luck.

Thanks to you both. Yesterday, I attempted the DVD preset with an Average Bit Rate of 4.4 Mbps and still got a filesize significantly above 2 GB. I don't have the MPEG-2 codec for MPEG Streamclip, which I'm assuming has to be in place to mux the audio. It is an SD file, btw.
Thanks so much for the screenshot. I attempted to use the SD DVD preset yesterday with an average Bit Rate of 4.4 Mbps, but still got a file size of about 2.5 GB. I'm not sure what I'm missing.
I know the MPEG-2 codec comes with Compressor 4... You might give it a try...
MPEG-2 plugin might be built in to Quicktime X... Nevertheless...
Click on your hard drive... Library... App. Support... Quicktime.
I'm having trouble getting Compressor 4 to let me use a video bit rate lower than 10.0 mbps.
