 What are the differences between Turbo.264 and Turbo.264 HD?
Solution The following is a comparison between Turbo.264 and the new Turbo.264 HD.

Turbo.264 HD is an advanced H.264 encoder, that is similar in some ways to Turbo.264.

Turbo.264 HD has more software features, faster encoding, and can produce up to 1080p HD content.


Software Support


Turbo.264 cannot work with Turbo.264 HD software.

Turbo.264 HD cannot work with the original Turbo.264 software.

Each hardware unit will need to use the special software application it came with.

Turbo.264 HD software comes with an activation key that is required for it to function.


System Requirements


Turbo.264 can work with both PowerPC and Intel Macs.

Turbo.264 HD is for Intel Macs only, and needs OS X 10.5.6 or greater.


USB Connection


Both Turbo.264 and Turbo.264 HD require an USB 2.0 connection.  They work best with a powered USB 2.0 hub, or an USB 2.0 port that was built into a Mac at the factory.

Turbo.264 and Turbo.264 HD cannot function on the same Mac at the same time.  Only one can be used for encoding at a time.


Maximum Resolution


Turbo.264 is an USB device that can assist in encoding to the H.264 format.  It has a maximum resolution of 800 by 600, and can stretch that anamorphically to 960 by 540 for use with Apple TV.

Turbo.264 HD is an USB device that can assist in encoding to the H.264 format.  It has a maximum resolution of 1920 by 1080 (1080p).  


Maximum Encoding Speed


Turbo.264 has a maximum speed that is determined by the H.264 encoding chip it uses.  It does not use as much CPU as possible.

Turbo.264 HD leverages the speed of the Mac it's attached to - the faster the Mac, the faster it can export.  It uses as much CPU as necessary - the amount varies depending on the Mac model.

For every video file, Turbo.264 HD should encode at the same rate or faster than the original Turbo.264.  The larger the resolution of the output file, the larger the encoding difference.


Export Format Presets


Turbo.264 has the following export format presets:

iPod Small
iPhone
iPod Best
Apple TV
Sony PSP
YouTube

Turbo.264 has those same presets, plus some additional ones:

iPod Small
iPhone
iPod Best
Apple TV
Sony PSP
YouTube
YouTube HD
HD 720p
HD 1080p

Turbo.264 HD also offers many more custom preset options than Turbo.264.


Application Support


Both applications install a special QuickTime component on your Mac, at this location:

Hard Drive/Library/QuickTime

In general, all applications are free to use the Turbo QuickTime component, once it is installed on a Mac. Some applications may need to be slightly updated, so that they can call upon Turbo.264 or Turbo.264 HD via QuickTime.

Custom export format presets made with Turbo.264 HD can be accessed via this QuickTime component, in other applications.   This is not true with Turbo.264.


Camera Support


Turbo.264 cannot detect any video cameras that are connected to your Mac.

Turbo.264 HD can detect many AVCHD cameras that are connected to your Mac.  It can take video files directly from cameras and encode them to H.264, maintaining HD resolutions.


Built-In Editor


Turbo.264 does not have a built-in editor.

Turbo.264 HD has a built in editor, used to select what sections of each video file you wish to export to H.264.



Game Console Support


Turbo.264 exports do not always work with a PlayStation 3 or Xbox 360

Turbo.264 HD exports do work with a PlayStation 3 or Xbox 360.  For example, a HD 1080p export will play on the PS3 or Xbox 360, from an USB thumb drive.
