This was mentioned in a previous post. I have to encode .mpg’s for our Nexus media server. It is possible to create muxed files in Compressor but you have to do a quick file conversion in MPEG Streamclip to get a .mpg file.
Open Compressor and select and set up for MPEG2 Encoding. In the Inspector click on the Encoder tab (2nd from left) and you’ll see Video Format, Quality, GOP, Extras. Go to Extras and select Multiplexed MPEG-1/Layer 2 Audio. That’ll give you an MPEG-2 Transport stream with mlutiplexed audio. This encoding will take the normal time as if encoding for a DVD. I take this file and drag it into MPEG Streamclip. It is a very quick file conversion and the audio will take a slight volume hit. File-export with MpegwithMP2 Audio. After exporting the file, the extension will end with .mpeg – delete the e so that the extension is .mpg
