Codec: ''H264'' leads to better videos than ''mp4v'' but is '''lots''' slower. I strongly recommend to use the ''mp4v'' codec.

Size: Usually the smaller video dimension is the height. Therefore setting the video height to the phone screen height (320px) is reasonable. Instead of always calculating the corresponding width use the canvas-aspect parameter, VLC will then do it for you. Only go larger if you plan to watch iPhone movies also on larger screens. In this case, the limiting size will most probably be the width (max 640px).

−
Bitrate: 768 kbps shows good results and reasonable file size. If you have action movies with many fast movements even 1025 kbps are recommended.

Codec: ''mp4a'' works nicely. ''aac'' was not tested.

Bitrate: For listening with earplugs 160 kbps are sufficent.

Sets the height to the screen height, the correct width with canvas aspect, the video codec is MPEG-4 video and the bitrate is 768 kbps
 
−
 
 
−
'''acodec=mp4a,ab=160,channels=2'''

−
Codec for audio is MPEG-4 audio, bitrate 160 and channels = 2 means normal stereo output.

'''soverlay'''
 
  
−
Burns the subtitles in the movie. The default size is large enough to be readable.

In the initial state the width is fit to screen. If you press on the zoom button in the top right it zooms in and fits the height and crops the borders on the left and right.

iPhone Video Conversion Hints

For a more complete description read the IPod video conversion guide! Here you find only small hints! The following has been tested for VLC media player 0.8.6i.

In the initial state the width is fit to screen. If you press on the zoom button in the top right it zooms in and fits the height and crops the borders on the left and right.
