Hi I work for a live broadcasting company that broadcasts live sports races. As part of our services we provide DVD’s of races after the race has completed. This is a time dependent service as we want the DVD’s to be available with menus ASAP after the race for sale.

Our current system:

We capture using a Canopus (MVR) Media cruise Video Capture system

At the following formats.

Video: 720 * 576 MPEG 2 @ 6MBPs

Audio: MPEG 2, 48 KHz, 22.4 kbps

Format: 4:3, PAL, outputting *.m2p,*.m2v,*.m2a.

This is then opened using Ulead DVD Workshop 2 which contains menu templates specifically designed so our staff can use them.


Ulead format

MPEG Files
24bit, 720 * 576 @ 25 fps (DVD PAL)
4:3 Variable bitrate max 8 Mbps

Once the footage has been captured an average race of 5 minutes takes about 4 minutes to burn once the race is over. No video converting required.


Our new system:

For the new system we decided to use a new capture system..

The new system uses a Matrox R2 XT capture card which uses Adobe Premiere Pro 2 to capture the footage.

The capture settings are set at:


Adobe capture settings:

Video: PAL, 720*576, 4:3 MPEG-2 Encoding at 10Mbps
Audio: MPEG 2, 48 KHz, 22.4 kbps

Ulead Settings:

Same as per Canopus system.

The Problem:

The new system takes about 20 minutes to burn the first DVD. Subsequent copies take the normal 4 minutes a copy. The problem is when Ulead decides to burn the combination of menus + footage it takes 15 minutes in a stage called “converting video”. This stage takes about 10 seconds on the Canopus system.

The settings from Premiere Pro 2 are per DVD spec and are the same as being captured through Canopus. The only difference is that premiere pro 2 saves the file as an .avi compared to the .m2v of the Canopus.

There is no option to save the output file of the Adobe as a different format during capture.

Any help solving the problem would be greatly appreciated. Im not sure if this is a problem with the realtime MPEG2 encoding of the Matrox/Adobe system or a translation issue between the system and the Ulead system.

I don't recall where in the Premiere project settings, but you need to set the format to MPEG-2 I-Frame or some such before capture.

Looks like you are capturing to a DV format and a more intense conversion is needed to go to MPEG-2.

yes it is currently being captured to MPEG-I which is why im confused as to the need for ulead to recode the footage. I might try a different capture software, hopefully virtual dub works with the matrox
