View Full Version : Techniques and tricks to make hi-quality low bitrate VGA-res MPEG's

This thread is for people who have a VGA-resolution Pocket PC (e.g. Dell Axim x50v, iPaq 4700 etc).

We found ways to make very high quality VGA-resolution MPEG's (can be played with PocketTV or Betaplayer on the Pocket PC, and by WMP on the desktop) at relatively low bitrate, using some advanced features of tMPGEnc (a free MPEG converter available from www.tmpgenc.net ), combined with some other tools and techniques.

The result is DVD-quality at 1.7 Mbps or less (i.e. 2 to 3 times lower bitrate than DVD).

You can see one example here:

http://pockettv.com/mpg/vga/5e-640x480-1.7Mbps-v3.mpg

If you compare the file above with our previous demo file (http://pockettv.com/mpg/vga/5e-640x480-1.7Mbps-v2.mpg), you will see a noticeable improvement in quality with the same file size (in the new file, there is no blocking artefacts in the fast motion scenes).

We can tell you how we produced this hi-quality demo and provide the templates that we have used, and you should be able to generate MPEG files of the same quality for your DVD's (one movie will fit in a 1GB card).

Depending on the type of video contents, this quality can be achieved with even lower bitrates (e.g. 1.4 Mbps).

Please have a look at our test file, and if you are interested to know how we achieved this, let us know here.

I've been using Nero's Recode 2 software set to "Portable PC" defaults and this works okay.

You can always easly tweak the setting for your display & file space.

I'm getting dvd quality with files 400mb in size and 128 bitrate audio.

I've tried everything else out there, nothing is as simple to use or as fast as this.
