TMPGENC 3.0 produces bigger encoded files than TMPGENC 2.5

Archived from groups: rec.video.desktop (More info?)

I had been encoding my half hour video programs using tmpgenc 2.510. I
recently upgraded to tmpgenc 3.0. The 6 Gig AVI DV file was being encoded
to a 800 Meg or 1 gig file, making for me to easily get 4 or 5 programs on
one DVD disk. I was using the default tmpgenc 2.5 template with no changes.
Using the default DVD template for the DVD encoding for 3.0 will result in a
1.9 gig file. I couldn't fit three of these files on one DVD disk.



Looking at the properties of the version 2.5 encoded file (as per DVD
Workshop's video properties), it shows the following:



Video



Video Type: MPEG-2 Video, Lower Field First

Total Frames: 52.136 Frame(s)

Attributes: 24 Bits 720X480

Data Rate: Variable bit rate (Max. 8000 kbps)







Audio



Audio type: MPEG Audio Layer 2 files

Total samples: 83,501,101 Samples

Attributes: 48000 Hz. 16 Bit. Sterio

Layer: 2

Bit rate: 384 kbps





In an effort to duplicate everything from the DVD Workshop's properties info
before encoding the tmpgenc 3.0 session, the resulting properties of the
file is as follows (still twice the size of some of the other files which
was as look as 780 Megs in size).



Video



Video Type: MPEG-2 Video, Upper Field First

Total Frames: 52.155 Frame(s)

Attributes: 24 Bits 720X480

Data Rate: Variable bit rate (Max. 8000 kbps)







Audio



Audio type: MPEG Audio Layer 2 files

Total samples: 83,531,532 Samples

Attributes: 48000 Hz. 16 Bit. Sterio

Layer: 2

Bit rate: 384 kbps







Can someone tell me what can be done to downsize the resulting file to
1 Gig and still maintain the 8000 kbps DVD standard.



Thanks in advance for any suggestions or comments on this.
