DVD low resolution with TMPGEnc

[Georgeo57]

I encoded a 5 minute 720x480 AVI capture with TMPGEnc using the DVD low resolution output option and selecting MP2 audio. The MPEG clip came out to be over 300 MBs. What did I do wrong?

When you encode with TMPGEnc using the wizard it will assume that you want to use the max bit rate size possible for the resolution that you have chosen, unless you choose otherwise by un-checking auto and adjusting the bit rate yourself. You could have a low resolution setting with a high bit rate and have a large file.

Frame size (resolution) has nothing to do with file size. That may be what is confusing you. 720 x 480 is not "low resolution". That's a full resolution frame size....the absolute maximum allowed for DVD-legal MPEG2 video in NTSC land. Where resolution (frame size) comes into play is in making more efficient use of your available bitrate, especially on lengthy videos that go 3-4 hours or more. Determine how much video you will be putting on your DVD or VCD project (in minutes) and use the bitrate calculator on this site to find the correct VBR setting.

Good advice. Here's a link to the DVDRhelp Bitrate Calculator.
