MPEG 2 HD transport stream from software encoding?

any ideas?

Tsunami and Canopus Procoder both can.

But Procoder does it SO MUCH better.

I just encoded some HDCAM footage to transport streams using both.

The client wanted the low bitrate D-VHS standard of 14.1 mbps.

There was a lot of motion on this footage with quick pans and zooms.

Tsunami was completely unable to encode the footage at that rate. It took a 36 mbps rate (blu-ray 1x maximum) to be able to encode the footage and keep it looking nice during the fast motion.

Procoder however, handled it like a champ. The original footage looks just as good at 14.1 as a transport stream then as its source file.

For reference The HDCAM footage was 40 minutes long and took about 33 hours to encode on a P4 2.5GHZ system with 1GB Ram. I had it on "highest quality" just above mastering quality. I suspect it could have been on a lower setting and still maintain a good image.

The final size of the mpeg2 transport stream was 4.1GB

one last thing, the HDCAM footage was 1080P and the client had to have it at 720P so that resizing probably added to the overall compression time as well.
