TMPGEnc 4.0 XPress Version 4.7.4.299 - January 11, 2010
Added	AAC 5.1 ch (6 channels) import support. (Importation of an MPEG-2 TS file containing an AAC stream up to 5.1 channels is now possible.) In addition, when importing an AAC stream you can manually set the number of channels in the "Clip properties" stage of the "Clip editor" window.
Added	Multistream selector function in the MPEG file reader. You now have the possibility to select a specific video and audio stream when the MPEG-1/2 source file contains several video and audio streams.
Added	Support of the Microsoft TV recorder file format "WTV". (WTV file importation is possible on the computer that recorded the file, or can create such files, and are not copy-protected.) Learn more about TMPGEnc 4.0 XPress and Windows Media Center!
Improved	MP4/AVCHD File Reader updated. Should allow the importation of files that could not be previously imported, and solve the playback speed issue.
Improved	YUV color space information contained in the source file is now taken in account when imported through the MP4/AVCHD File Reader. If no color space information is available, the BT.709 or SMPTE 170M color space is automatically selected according to the pixel rate.
Improved	When outputting an MPEG-4 file, the YUV color space is selected according to the resolution and framerate, the color space is then converted to the selection before the encoding stage.
Improved	When the Batch encode tool fails to retreive the automatically saved batch list it now displays an error message, erases the batch list and resets.
Improved	Following a silence, the audio uniformization filter could highly increase the volume, resulting in an explosion-like effect. The improved filter reduces the occurence of such an issue.
Fixed	An audio gap would appear when continuing to import a file through the DirectShow reader without seeking it.
Fixed	The DirectShow Reader audio management has been adjusted, allowing the DivX Reader to correctly get the audio.
Fixed	AAC decoding now resumes instead of stopping after some corrupted data has been encountered.
Fixed	Some flawed header or trailer MPEG files are now importable through the MPEG File Reader.
Fixed	The Windows Media Audio file output does not allow the registration of unexpected file extensions anymore.
Fixed	The DivX file output basic mode would always set the level to Medium even when Low or High was selected.
Fixed	In the DivX file output, reducing the profile would display a wrong framerate in the window.
Fixed	In the DivX file output, it was possible to select a non-standard MP3 bitrate.
Fixed	The Batch encode tool would sometimes display an error message when started, and not display it when restarted.
Fixed	The WAVE file output advanced mode would note .1 ch even when no .1 ch was selected.
Fixed	The Smart sharpness filter picture edge processing is stricter, reducing the occurence of possible problems.
Fixed	The seek bar motion is now smoother in the Preview display window, or when disabling the thumbnail display in the Clip cut-edit window.
Fixed	Other minor fixes.

Improved	The MPEG-4 AVC file output bitrate control mode 2 pass Constant bitrate is removed. (Project or output setting template containing the 2 pass Constant bitrate option is automatically adjusted to 1 pass Constant bitrate.)
Improved	The MPEG-4 ISO file output has Maximum bitrate, VBV buffer and Quarter pixel options added, allowing improvement of the picture quality. Some settings of the "Video" tab are now in the "ISO" tab.
Improved	DivX file output "File" tab displays a warning that used to appear when moving from the Format stage to the "Output" stage.
