Cowon, purveyor of the most
From a video perspective, the A3 features a 4-inch TFT LCD display with an 800x480 resolution and integrated component, S-Video, and composite video output. Like most Cowon players, the A3 natively supports an astounding array of file formats and codecs, including video formats such as AVI, DivX, XviD, MP4, ASF, MKV, VOB, OGM, WMV 7, H.264, MPEG, DAT, and MTV--all with a maximum resolution of 1280x720 at 30fps (yes, that's HD, people). As a music player, the A3 can play MP3, WMA, FLAC, OGG Vorbis, OGG FLAC, Apple Lossless, AAC/AAC+, AC3, True Audio, Monkey's Audio, MusePack, WavPack, G.726, and PCM audio formats. You also get support for subtitles, ID3 tags, lyric tags, the full slate of Cowon's JetShell audio enhancement features, a photo viewer (JPG, GIF, PNG, TIF, BMP, RAW), a 720x480 video recorder, line-input recorder (FLAC, WMA), voice recorder, FM radio, and radio recorder. If that's still not enough for you, you can always nerd-up to the.
For all you chipset trainspotters out there (all 10 of you), the A3's internal architecture is built around the Texas Instruments DaVinci chipset.
The demo video below is from the Frenchies over at GenerationMP3, so forgive the hideous trance music.
