Tip & How-To about Global Star Software TMPGEnc DVD Author 1.5 (12358) for PC

Do I use CBR or VBR for my TMPG v4.0 Xpress MPG2 encoding ?

VBR (Constant quality)
Used to make high quality clips no matter the file Compared to VBR (Average bitrate) this mode generates a bigger file but insure the best picture quality control possible.

VBR (Average bitrate)
Encodes using the VBR bitrate control mode, allowing for a smaller final output file size but requiring a longer processing time.


CBR (Constant bitrate)

This is the Usual encode mode for most commercial DVD.
Because the encoding process is streamlined this mode allows a fast encoding but creates relatively big file due to poor optimization. This mode is usable when file size is not a constraint. Encodes using the CBR bitrate control mode, allowing for faster output but without bitrate allocation optimization, resulting in a bigger file size and possible picture quality degradation in scenes with a large amount of motion.

memory loss on ipod

The ipod nanos the smallest product in the Apple iPod line. The fourth generation Nano comes in two different capacities, each capable of holding thousands of songs.
  1. The fourth generation iPod Nano comes in 8 GB and 16 GB models. The 8 GB version can hold 2,000 songs, and the 16 GB version can hold 4,000 songs.
  2. Tips
  3. Song capacity estimates are based on music encoded in Apple's proprietary format at a standard, average bitrate. The higher the bitrate, the better the quality. Songs deviating from Apple's standard (for example, CD-quality music or high bitrate MP3s) will use more disk space.
  4. History
  5. Nano's predecessor, the iPod Mini, was released on January 6, 2004, and was available with a 4 GB hard drive. The Nano was first released on September 7, 2005, and was the first iPod to use flash memory. It was first available in 2 GB and 4 GB versions. The fourth generation Nano was released on September 9, 2008.
  6. Size
  7. The fourth generation iPod Nano is 3.6" tall and 1.5" wide.
  8. Video
  9. The third generation Nano, released on September 5, 2007, was the first Nano to feature video playback. Storing videos on Nano can dramatically reduce the amount of songs it can hold.

limited downloads on mp3 player

Probably because your songs are at a very high bitrate eg. 320 (CD quality) as opposed to 128 (average quality). Songs at a higher bitrate take up more space. So the Zen Stone can hold 250 songs at a bitrate of 128 but only, say, 150 at a bitrate of 320. Your solution would be to use http://www.dors.de/razorlame/index.php to decrease the quality of your mp3 & make the file size smaller.
