Need advice Xvid AVI to MPG2 Generates large filesize

[tadrian]

I have a video file with the following info:

Codec Name: XVID Mpeg-4
Audio: MPG Layer 3 48000hz
Video Bitrate: 1227Kbps
Duration: 1:11:52
Filesize: 697 Mb
Type: AVI
Quality: 56%
Size: 576*320(16:9)

I have tried to convert this file to mpg as my tvix player can not display it.

* I have tried to import it into Adobe Premiere and Export it as MPG2, result: 3Gb file
* I have tried TmpgEnc Plus and export it as Mpg2 audio bitrate 128kbs, video bitrate 1026, 25fps, Result: 1,7Gb file

What am I missing , is there any way to convert this file to mpg2 with a filesize under 1gb.

Thanks
Thomas

This is not a "dvd to" conversion. Moving you.

I guess that tmpgenc plus has encoded too much, www.videohelp.com/tmpgenc#problems (first problem) and often occurs for mp3 vbr audio. Check the mpg2 if it is 1:11hrs.

MPEG 2 under 1 GB? When your original AVI is 700 MB? You'll lose a LOT of quality.

As a general rule, Xvid to DVD conversion will consume at least 3 - 4 times the space to maintain similar quality levels. Mpeg4 variants (Xvid/Divx etc) compress a lot more than Mpeg2 does, combined with the fact that many of these files are also running at a lower resolution to allow more efficient use of the bitrate they have. When you convert to DVD you increase the resolution and the bitrate. Bitrate x running time = size. More bitrate, bigger files.

As Kschange has pointed out, 71 minutes at under 1 GB at full D1 will be pretty low quality. It is the equivelent of putting 4 hours on a single layer disc.
