HT G30 phone supports video formats such as 3GP, AVI and MP4. But we would recommend using MP4 format to get fairly image and sound quality. Based on experience, here are the video specifications optimized for playback on mobile phone HT G30:

1. 3GP
   • Resolution: 176 x 144 px (qcif)
   • Framerate: 15 fps
2. MP4
   • Resolution: 320x240 px (qvga)
   • Framerate: 5 fps (15 fps untuk resolusi qcif)
3. AVI
   • Not tested but probably similar to MP4 (which differ only container)

To convert video to MP4 format supported by mobile HT G30, just type the following command line:

$ ffmpeg -i <source_file> -sameq -s qvga -vcodec libxvid -acodec libfaac -r 5 <destination_file>.mp4

Explanation of Command Line:

-i = Video file as input sources (MPG, WMV, 3GP, etc.)
-sameq = Same quality as original source
-s qvga = Resize video size to 320 x 240 px (qvga)
-vcodec libxvid = Using XviD (MP4) video codec
-acodec libfaac = Using FAAC (AAC) audio codec
-r 5 = Video frame rate = 5 FPS (Frame Per Second)

With this configuration you will get the best video picture quality on your phone. But with a small framerate (5 fps) your video will look a little flicker. If you want a smooth result, you can change framerate with greater value and lower video resolution as compensation.
