Default 2-stage AMV encoding, the smarter way

It would seem logical that just using AMV convertor 3.68 directly would be the best approach to encoding to AMV files for the 1.5" display Yepo 757F.

It would be logical but WRONG.

I would strongly suggest that you pre-convert to AVI first using freeware Pocket DivX Encoder 0.03.60

Advantages:

(1) more likely to produce "playable" video clips that don't freeze
(2) better video quality
(3) more options to adjust video shortcomings for 1.5" display
(4) smaller filesize for video clip
(5) Pocket DivX Encoder can convert many more video formats
(6) faster (yes, two stages are faster than one)

Here is an example of my testing:

I started testing with a short internet downloaded MOV video clip. The original filesize was 38MB.

I then encoded directly with AMV Converter 3.68 set at HIGH fps and HIGH video quality. From start-of-encoding to finish took 4:35 minutes and produced a playable 128x96 15.2MB AMV file.

I then tried the 2-stage approach. I used Pocket DivX Encoder to produce an intermediate 128x96 AVI file. I then used AMV Converter 3.68 to produce the final AMV file.

The video clip produced by using 2-stages was 12.8MB and higher quality. It was also faster. The first stage took 1:20 minutes and the second stage took 30 seconds. Combined time was under two minutes compared to the 4:35 minutes by just using AMV Converter alone.

Here are the settings I used for Pocket DivX Encoder:

Device: Palm Tungsten
B-Frames: ON
2 Pass Encoding: YES
Codec: VHQ (FFmpeg MP4)
Audio Normalization: OFF
Video Quality: 80
Audio Quality: 3
Saturation: +12
Contrast: +10
Clip Size: 128x96

BTW, try arrow keys instead of mouse for finer control of clip size setting.

Here are links to my actual AMV files produced (15MB and 13MB):
