TMPGEnc Plus Version 2.524.63.181 - December 16, 2004
Changed	The formats for the project file and the template file have been changed. Therefore, project created with the new version cannot be used with older versions.
Changed	[Project wizard (Step 4/5)]: in the media pull-down selection, DVD 8.5 GB (Double Layer) has been added, for the bitrate setting and size graph
Changed	In the MPEG system multiplexer, the max. bitrate is written instead of the average bitrate for the multiplexing rate. It shortens the outputting process.
Changed	[MPEG Setting - GOP structure]: Even if Closed GOP is not selected, the GOP structure is now compliant with the MPEG standard.
Changed	Created MPEG-2: the sequence display extension value in the header is now DVD compliant.
Improved	Image quality for MPEG-1 with long-GOP, has been improved.
Improved	Encoding of scenes using still-image, has been improved.
Improved	Decoding process of MPEG-video is faster.
Improved	CRI Sofdec MPEG Decoder can read WAVE files (48 / 96 khz, 16 / 20 bit, 1 / 2 ch).
Fixed	Errors related with encoding using multi-thread.
Fixed	The encoding of MPEGs with GOP structure using only I and B pictures, has been improved.
Fixed	[MPEG Setting - Video]: The Aspect ratio 2.21:1 for MPEG-2, was set to 2.11:1 .
Fixed	[Output to file - AVI file / WAVE file]: when clicking the Cancel button in the [Sound Selection] dialog, the dialog was shown again.
Fixed	[MPEG Setting - Quantize matrix]: if saving an existing template under a new name, it could not be deleted.
Fixed	[MPEG Setting - Quantize matrix]: if saving a template under no name, memory access violations occurred.
Fixed	When reading empty files (zero data), it could take a very long time to show the error message.
Fixed	MPEG source files with invalid data could sometime, make the encoding process freeze.
Fixed	AVI files created with TMPGEnc, when played with Windows Media Player could stop in the middle, with the message "Invalid file".

TMPGEnc Plus Version 2.521.58.169 - September 26, 2003
Improved	The new version of "CRI sofdec MPEG decoder" is included. Now, it is possible to open a maximum of 20 sequences instead of 8.
Improved	In the project wizard, for the setting concerning the bitrate, the file size in MB will be shown instead of the duration for "CD-R 74min (VCD/SVCD)" and for"CD-R 80min (VCD/SVCD)".
Improved	When error occurs during "Prefetch Video", the details will be shown..
Improved	When using "DirectShow Multimedia Reader", from now on only Linear PCM, 8/16 bit, 1/2 will be accepted for the audio input.
Fixed	When "CRI sofdec MPEG decoder" was chosen in the VFAPI plugin, errors could occur to open sequence files via "DirectShow Multimedia File Reader"
Fixed	Problem occuring when using an external MP2/MP3 encoder. For certain settings, the CRC value or the error protection could be changed.
Fixed	When the audio was re-sampled in high quality mode, if the input was monaural, errors could occur.
Fixed	During the encoding, some "Drag and drop" files could be accepted from the Explorer.

TMPGEnc Plus Version 2.520 (2.520.54.163) July 17, 2003
Added	Includes the MPEG decoder CRI Sofdec. Now, input of MPEG-2 files is a standard feature. Plus, the picture quality (brightness, color) shown on your pc display will be close to the one on your TV. So the editing will be easier. *when using CRI sofdec: remove the check on [ Output YUV data as Basic YCbCr not CCIR601 ] [ Setting ] => [ Quantize matrix ] => [Output YUV data as...] *when using CRI sofdec, you can open a maximum of 8 sequence files as a movie.
Fixed	Made minor corrections.

TMPGEnc Plus Version 2.513 (2.513.53.162) June 12, 2003
Fixed	In the MPEG Setting dialogue under the GOP tab, even if the "Force picture type setting" was not enabled you could click the "setting" button.
Fixed	Reading an animation using DirectShow, could result in incorrect audio or a memory access violation error.

TMPGEnc Plus Version 2.512 (2.512.52.161) May 20, 2003
Fixed	When selecting an MPEG file in MPEG Tools, Multiplex, a message saying "does not support multiplexing a DVD Sub-Picture stream to a system stream" was displayed.
Fixed	In an environment where multi-thread was enabled, choosing "Highest Quality" as Motion Search Precision would cause the encoding to stop halfway with an error saying Memory access violation error.

TMPGEnc Plus Version 2.511 (2.511.51.160) April 28, 2003
Fixed	Adding too many chained files, would cause the program to close.
Fixed	On systems where Windows Media Player 9 is installed, reading MS MPEG-4 AVI files via the "DirectShow Multimedia File Reader" would cause an error to occur.
Fixed	Multiplexing MPEG-Video stream without a sequence end-code would cause the PTS time stamp of the picture included in the last GOP, to be invalid.
Fixed	Choosing "File" => "Exit" during encoding would not close the program.
Improved	Improved the processing of the file so that, if possible, securing and releasing the memory of a huge block is not repeated.
Fixed	Made minor adjustments to the size of each window.

TMPGEnc Plus Version 2.510 (2.510.49.157) January 18, 2003
Fixed	In the Environmental settings dialog window, General tab, checking "Enable multiplex with..." and choosing audio file other than mp1, mp2 or mp3 format would raise an error when starting to encode.
Fixed	In the MPEG settings dialog window, GOP structure tab, when "Detect Scene Change" and "Force picture type" settings were both selected, closing the dialog window and reopening it would clear the "Force picture type" checkmark.
Fixed	In the MPEG settings dialog window, System tab, choosing "MPEG-1 Video-CD (non-standard)" would in fact select the "MPEG-1 Video-CD" setting.

Fixed	The VFAPI plug-in TMPGEnc.vfp would not take the main application settings into account.
Fixed	Broken index would occur when outputting a high data-rate (for example high-resolution or uncompressed AVI file larger than 4GB).
