Elgato has introduced iPhone video export to the features available to users of its Turbo.264 video encoding accelerator device.

The Elgato Turbo.264 (£69) is a hardware encoder in USB stick format, which accelerates video conversion on the Mac by up to ten times. It accelerates video export from within popular Mac apps, including iMovie, QuickTime, Final Cut Pro and Eye TV.

The new iPhone video export feature is contained within a free software update for the USB product, which the company has made available for free download.

Elgato Turbo.264 now supports iPhone video, offers user-customisable settings for video conversion, and enables manual selection of soundtracks from DVDs.

The update to Turbo.264 version 1.1 includes improved widescreen detection, performance improvements, and a number of bug fixes.

Two iPhone presets exist; one for 4:3 source material produces 480 x 360 resolution video, while 16:9 source film is encoded as 480 x 270 pixels. Users can now also set, save, and name their own presets.

Widescreen format feature films are sometimes encoded on DVD as 16:9 video with horizontal black bars at the top and bottom (letterboxed). The Elgato Turbo.264 update recognises such content and automatically offers Widescreen encoding.

The update provides encoder firmware and software decoder optimisations that should improve performance, video quality, and stability.
