creating mpeg-2 – why no audio?
A network wants our show delivered via ftp as an mpeg-2, but whether i tried it out of an FCP timeline via Compressor, or make a QT them drop it onto a droplet, i get a video with no audio. Any help?

and all you compressor settings are?
Have you setting Multiplexing in the Extras tab?

If you’re using the Elementary Stream setting in Compressor I don’t think it’ll export audio.

settings are all default mpeg-2 (Program stream) Compressor settings
Extras / Multiplexed MPEG-1/Layer 2 Audio is checked and Program Stream selected (both of these by default)
thanks for the attention
Thanks again!

delivery specs specify “CBR Bitrate: 8Mbs” and the default Compressor setting was two pass VBR, avg 15Mbps and Max at 20Mbps, so it seems to be making the video at a high enough quality, though on playback, it sure doesn’t look like something i would want to air! : )
Thanks again!

8Mbs is normal for SD if that is what is required. If the specs ask for CBR 8Mbs, why are you using VBR at higher bit rates?

Try Transport Stream. That’s what I use, and I get audio every time.

Hi Tad,
The audio is there, but QT can not play it.
Play the file with MPGStreamclip to check that.

I am trying to make an MPEG-2 file from a quicktime movie using Compressor and the video is fine but there is no audio. I have tried to make it exporting straight from Final Cut Pro and also just as a self contained quicktime movie – and no joy either way. Anyone any ideas? All suggestions very, very welcome.

Hi Dave
I used both Programme and Transport Streams, both unsuccessfully. Video in MPEG2 fine – but no audio.
The audio is just part of the preset MPEG audio @ 48kHz.
To give the full background. I filmed on XDCAM HD and made the movie in final Cut Pro an an HD movie. I have tried making self contained and reference qt movie files and imported them to Compressor – and also exported direct from FC Pro into Compressor. Nothing works. The resultant MPEG2 video is fine – but the audio just disappears. HELP!!!!!!!!!
