The program I've been using to put videos on my player is MediaGo. Its available as a free download from the Sony website. It will convert the videos into the appropriate format and put them on your Sony player. I don't know if it will handle all of the formats listed above, but it will handle .avi and .mp4.

I hope this helps.

Here are the informations from the Manual of the close A820 model:

Video File Format:
MP4
Extension .mp4, .m4v

Codec Video:

AVC (H.264/AVC) Baseline Profile, Level 1.3, Max Bitrate 768Kb/s.
or
MPEG-4 Simple Profile
, Max Bitrate 2500Kb/s.

FPS:
30 i/s max.

Resolution: QVGA (320x240) Max.

Codec Audio:

AAC-LC 2 channels max / 24,32,44,48 Khz / Max Bitrate 288kb/s per ch.

As I don't know which program you use, I can't be much more specific. You will find some settings on the web for command-line tools like ffmpeg or Mencoder. But most people use GUI programs. I can give you 3 names.

Avidemux: Getting a working MPEG4-ASP file is easy with Avidemux. AVC files are more difficult to get right through the extended options interface.

Handbrake: Provides a simpler way to produce great MPEG4-ASP and AVC files. Just select the basic iPod preset (320x240px).

WinFF: Has one Walkman Xvid preset that I saw but have never tested.

Those 3 softwares enable you to save your best presets.

--------------------------

What is difficult with AVC is to stay within the right Baseline Profile, that means to avoid unsupported features belonging to upper AVC profiles. Do do so, the 4 main H.264/AVC parameters you must be sure to set to whatever NO/ZERO/0/Unselected means in your software are:

  • BFrames (bframes, bf=0)
  • CABAC (---no-cabac, cabac=0)
  • Weight Prediction (-wpredp, weightp=0 )
  • 8x8 Adaptive DCT Transform (--8x8dct, no8x8dct, -dct8x8)

Happy encoding!

Meetoman: Thanks for the post above, its very helpful indeed.

I personally use Handbrake with the ipod setting. This works fine for my S639F, but for the A818 I have to change level=30 to level=13 in the Advanced tab.

I also find using 175 for video instead of the default of 700 has no impact on the video quality but does make a saving in file size.

If anyone has any other tips on optimising quality for Sony players please share them.

@winnyuk: You're welcome. I have set my own Handbrake H264 preset to level13, I set sound bitrate to 128kb/s and video bitrate to 400-500 or quality RF near 20-24. But as level30 works too with my E430, I didn't want to confuse.

@Sleeb: You can always go to the source by downloading Sony Manuals on their official web sites.
Here are the complete informations I got for the NWZ-A840 (WMV included):

Video File Format:
MP4
Extension .mp4, .m4v
WMV ASF, extension .wmv

Codec Video:

AVC (H.264/AVC) Baseline Profile, Level 1.2,1.3,2,2.1,2.2,3 Max Bitrate 10Mb/s.
or
MPEG-4 Simple Profile
, Max Bitrate 6000Kb/s.
or
WMV VC1 Simple Profile
, Main Profile, Max Bitrate 6Mb/s.

FPS: 30 i/s max.

Resolution: 720x480 Max.via TV output, however the device display is 400x240px.

Codec Audio:

MP4: AAC-LC 2 channels max / 24,32,44.1,48 Khz / Max Bitrate 288kb/s per ch.
WMV: WMA for WMV9 44.1 Khz / Bitrate 32-192kb/s (VBR and WM-DRM compatible). I guess 2ch also.

It always depends on the source video and your usage.
Now that you know the maximum this sony can play, you can still restrict yourself to the device screen size:
4:3 movie --> 640x480 px
16:9 movie --> 720x405 px
I've just downloaded a movie trailer at 640x268px, so roughly 2.4:1 ratio. For this geometry, with a bigger source movie your conversion would be:
2.40:1 movie --> 720x300 px
And so on... Beware that there are often differences between pixel ratio and output ratio. A 16:9 widescreen PAL DVD movie at 720x576 px is 1.25:1, but must be shown at 1024x576 px (16:9). So you must take this output ratio in account when converting. Sometimes you have movie whose ratio is 2.40:1 on a 16:9 presentation, where the black bars are already added. You just have to play it at the 16:9 ratio.
Have fun!
