    hello everyone, I just wanted to share the video profile i have been using to convert my media files to psp-compatible format. Below are taken from some website I've found last 2008 and have been using it since: Kudos and Credit to Caydr -- original author of the profiles


    PSP version video profile suggestion (56k)

    Hello, I started using MediaCoder about two weeks ago. I really appreciate this program and I'll be donating for sure.

    After the experimentation I've gone through, I would suggest for the PSP version that you add a few profiles. Sizes indicated are for a standard 25 minute anime episode:

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

    -Minimum Quality PMP (Animation, AVC widescreen)
    Audio, LAME MP3 ABR 64 Joint Stereo, no resample (as is), 3db, "level 1" conversion quality
    Video, Bitrate based 100kbps, H.264, PMP container, autoselect source, x264 backend
    Picture, 480x272, crop disabled, frame rate 15

    Output is watchable and subtitles are readable. I would call this the lowest watchable quality - going down even another 25 kbps to 75 results in a massive quality decrease. The viewing experience is not ruined, although you'd never want to use this setting on your favourite show. Some audio distortion. People with a 256 or 512mb card would find this useful, as output is generally below 36mb. 3db gain to overcome the PSP's relatively quiet speakers.

    -Low Quality PMP (Animation, AVC widescreen)
    Audio, LAME MP3 ABR 80 Joint Stereo, no resample (as is), 3db, "level 1" conversion quality
    Video, Bitrate based 150kbps, H.264, PMP container, autoselect source, x264 backend
    Picture, 480x272, crop disabled, frame rate 23.976

    Output is highly watchable. Quality is still not excellent, but significantly better than the Minimum setting. Notice the framerate is now at what seems to have become the "standard" anime fps. Audio is much better, but there's still some distortion in rare situations with a lot of competing sounds. Output is between 42 and 47 mb. This setting allows 20+ episodes on a single 1gb stick, which comes bundled with new PSP Slims.

    -Medium Quality PMP (Animation, AVC widescreen)
    Audio, LAME MP3 ABR 96 Joint Stereo, no resample (as is), 3db, "level 1" conversion quality
    Video, Bitrate based 225kbps, H.264, PMP container, autoselect source, x264 backend
    Picture, 480x272, crop disabled, frame rate 23.976

    This is the standard setting, with a very good quality to filesize ratio. I'd recommend this for most general viewing, although unusual shows such as Gankutsuou might require the High profile. Very little audio distortion, very little serious pixelization during action scenes. For some sort of masterpiece like Death Note, Monster, Planetes, Cowboy Bebop, etc, I would probably switch to High Quality, just because they aren't something you'd want to compromise on. Output is around 51-56 mb.

    -High Quality PMP (Animation, AVC widescreen)
    Audio, LAME MP3 ABR 112 Joint Stereo, no resample (as is), 3db, "level 1" conversion quality
    Video, Bitrate based 300kbps, H.264, PMP container, autoselect source, x264 backend
    Picture, 480x272, crop disabled, frame rate 23.976

    Output is excellent quality, with no audio distortion or noticable pixelization during normal viewing. No noticable block/tile effect, no fringing, etc. Video problems are only visible when fast action scenes are paused, but even then they're not significant. Beyond this setting is almost excessive. Output is between 72 and 78 mb.

    -Maximum Quality (Animation, AVC widescreen)
    Audio, LAME MP3 ABR 128 Joint Stereo, no resample (as is), 3db, "level 1" conversion quality
    Video, Bitrate based 450kbps, H.264, PMP container, autoselect source, x264 backend
    Picture, 480x272, crop disabled, frame rate 23.976

    The highest reasonable quality setting. Even shows with a great deal of fast movement and very high quality, detailed art should appear to be virtually UMD quality even during pause. The extra sound quality isn't strictly necessary, since most encodes are done at cb128. Archival quality, as you would likely require a higher quality source (probably dvd-ripping from your personal collection) to see any noticable improvement. Common releases at 704x396 are encoded at around 850kbps, and that resolution has more than double the pixel data. Output is approximately 90-105 mb. Any visible artifacts were likely present in the source video.
