FCP to MPEG2 High bit rate
on Feb 22, 2006 at 6:08:50 pm

A TV station I am involved with has two FCP suites.
They need it to output 12Mb/sec MPEG2 CBR files for the PlayBox Station Automation equipment.
Compressor only goes up to 8Mb/sec.
Does anybody have a solution?

Most of the MPEG2 playback video servers for broadcast deliver content at 0.512Mbit/sex to 1.5Mbit/sec. HD content is delivered at 19Mbits/sec. 12Mbit is well beyond DVD's maximum of 10Mbit and seems impractical to me. Are you sure that your info is correct?

I think MegaPegX can do this. Digigami.com

DVD encoders are not used for this type of work. The MPEG-2 streams used in broadcast distribution typically are encoded at a bitrate around 10 - 25 Mb/s. Also you need to know whether you need a transport stream or a program stream, plus the MPEG-2 level and profile required. You can use machines like Telestream, Anystream or Digital Rapids for his type of encoding. Also there are a few manufacturers that make computer boards for this purpose.

Yes this is MPEG2 Program stream at 12Mb/sec. It is data streamed over a microwave then transmitted on a UHF channel. It does not use Satellite. I just wondered if I was Missing something as all the other Stations I have been at, use Edius Broadcast SDI Edit suites that have Procoder 2 built into them and you can have any Bit rate you wish. The encoding is very fast as these machines use Dual Dualcore Opterons and the encoding is distributed to the CPUs. By fast i mean it can encode a 90 minute DV Timeline to MPEG2 Programstream in 10.5 minutes.
I thought FCP could do something professional also. There is a visible diference between 8Mb/sec and 12Mb/sec.

Remember good ole' "Cleaner" from Discreet/Autodesk? It will do exactly what you need. It will encode MPEG2 up to 20Mbps. I use it to encode high bitrate MPEG2 for delivery via FastChannel. I have version 6, so I don't know about any other version. The only downside is that you really don't have a practical way to properly view the encode. It will look trashy when you play it back via Quicktime, but it will be right when played from a hardware MPEG2 board.

yo, troll, see the discrete editors thread wherein you posed the self-same question, without the "professional" dig and you'll read the following.


you could export a QT reference file from FCP and using something other than compressor to do the encoding. Can your Opteron box convert QT to MPEG-2?
