While Handbrake's 'Universal' and 'iPhone' profile will produce compatible files, it will do so at a lower quality level than the N900 supports, so it is worth using settings more closely tailored to the device's capabilities. | While Handbrake's 'Universal' and 'iPhone' profile will produce compatible files, it will do so at a lower quality level than the N900 supports, so it is worth using settings more closely tailored to the device's capabilities. | ||

The N900 supports a native resolution of 854x480 and does not support 1280x720. The actual limit is unknown, but using a resolution larger than the native resolution is not recommended as the resolution would be larger than the screen and therefore inefficient. | The N900 supports a native resolution of 854x480 and does not support 1280x720.

To encode video that will scale nicely to the screen aspect ratio, you can use either 240x144 (slightly larger than QCIF), 352x208 (slightly smaller than CIF) or 400x240 (N800/N810 only). Of course if your source video is in a 4:3 aspect ratio, then you should stick with CIF (352x288) or QCIF (176x144). The video player will letterbox or pillar box as needed. | To encode video that will scale nicely to the screen aspect ratio, you can use either 240x144 (slightly larger than QCIF), 352x208 (slightly smaller than CIF) or 400x240 (N800/N810 only).

The Decoders Support package adds AC3 audio support. AC3 audio is interesting because most DVD audio tracks are encoded in this format. This would allow you to copy the audio track without transcoding it. However, this is not necessarily ideal. Firstly, AC3 decoding will be done by the CPU, while AAC decoding is offloaded to a DSP which reduces power consumption. Secondly, you are not going to be able to take advantage of surround sound - meaning that storing a full 5.1 audio track wastes space. | The Decoders Support package adds AC3 audio support.

MKV is a superior format to both AVI and MP4, but is not fully supported as yet by the native Media Player in the N900. It supports multiple audio tracks, multiple subtitle tracks along with chapter support and more features. | MKV is a superior format to both AVI and MP4, but is not fully supported as yet by the native Media Player in the N900.

- | Support can be added by [http://maemo.org/downloads/product/Maemo5/decoders-support/ downloading the Decoders Support package] from Maemo Extras. However, MKV files will only play with mplayer which is still in development for Maemo 5/ N900. As such, it is not recommended at this time and there are significant performance costs when not using the built-in Media Player. | + | Support can be added by [http://maemo.org/downloads/product/Maemo5/decoders-support/ downloading the Decoders Support package] from Maemo Extras.
