Neue Version von VirtualDub verfügbar

Unter VirtualDub.org wurde am 28. Mai die Version 1.5.4 von VirtualDub freigegeben.

The main changes are a fix for a thread race condition and a workaround for the hang at the end of a 2-pass

DivX 5 operation. Also, I threw in bitrate calculation for AVIs under File | File Information.

Downloadbandbreite begrenzt

Nachdem die Bandbreite der Downloads mittlerweile ein bedenkliches Maß angenommen hat, habe ich diese jetzt auf 128kB begrenzt. Dies betrifft jedoch nur die Verzeichnisse mit den zum download freigegebenen Dateien. Alle anderen Daten sollten auch weiterhin in der gewohnten Geschwindigkeit zur Verfügung stehen.

DivX 5.0.4

DivX liegt ab sofort in der Version 5.0.4 vor.

Changed:

The new RC doesn't use Q=1 frames anymore

No stuffing used, bitrate can be too low in some extreme cases.

Strategy planning for rate control is much faster now

Better tracking of the planned RC strategy creating more consistent quality.

Fixed:

K6-2 CPU related crash resolved.

Not able to change Bitrate Modulation through CLI field.

During 1 pass quality-based, Quantizer can now be set to 1 with CLI

Multiple error windows no longer open upon entering wrong bitrate modulation option.

'Max Keyframe Interval' no longer accepts negative values

Multiple error windows no longer open upon entering wrong CLI option.

In the Quick Config CLI field, 'Enable Resize' was taking invalid options

Fixed CLI inconsistencies when "Restore codec's default" is pressed.

Max bitrate and encoding bit rate(average) was displayed same.

Fixed hitting tab in the CLI field to enable 'Use Bidirectional Encoding'

Fixed: remove -w in the Quick Config CLI field, 'Update Log file' option is not getting deselected.

When 'Psychovisual Enhancements' value is set to 4, in the Quick Config CLI field, mismatch in slider and label options.

1 Pass and Nth Pass™ undersized file should be fixed

Certain dark sequences would produce a long period of frames using a Quantizer of 31.

Psychovisual Enhancement field sometimes displayed "Custom" instead of Light when unselected

"Do not prompt with errors and warnings" would select itself when random characters were entered in the CLI after the "-key" option

When "-d 3" option was entered in the CLI field, "Source interlace" became blank.

Max bitrate would not update at times.

DirectShow decoder postprocessing slider became disabled with ATI radeon 9700 Graphics card

DirectShow decoder would "fast forward" when seeking backwards. This could cause synch issues when re-encoding DivX Files using the DivX Decoder Filter.

Various cosmetic fixes in the Encoder GUI
- Do not prompt Error unchecked as default fixed.
- Light Psychovisual enabled itself automatically when exiting the CLI field.
- Max bitrate reset itself to x10 the average when going in the "profile" tab

MPEG-4 "type Indicator" correctly set according to selected encoding parameters

No more green first frame at very high bitrates.

Decoder updates the display to the appropriate frame when seeking

Decoder remembers the postprocessing settings

Fixed some memory leaks related to Psychovisual and Nth Pass™ mode

Nth Pass™ RC is tweaked to minimize the usage of high quantizer

Nth Pass™ doesn't create an empty frames at the beginning of the clip

Brightness/Saturation sliders now working correctly.

Update der Hobbies-Seite

Tja, schon wieder sind rund zwei Monate vergangen, ohne dass sich sichtbar etwas hier getan hätte. Naja, das stimmt so nicht ganz, da ab und zu doch im Hintergrund gebastelt wurde ;-)

Jetzt gibt es allerdings wieder was neues zu lesen.

In meiner (viel zu knappen) Freizeit habe ich mich natürlich weiterhin meinen Hobbies gewidmet (Wer hätte das vermutet *g*). Aus diesem Grund habe ich heute die Hobbies-Seite upgedated. Viel Spass damit ;-)

Nachtrag zu DivX 5.03

Nachdem ich mit den Einstellungen, vor allem den Multipassencoding-Optionen, von DivX 5.03 rumexperimentiert habe, kann ich nur davon abraten das neue Feature zu benutzen. Die Qualität ist nicht wirklich berauschend. Zum Glück gibt es aber immer noch die Möglichkeit mit dem guten alten "2-pass" zu encoden. Der Codec bietet das 2-pass allerdings unter dem Namen "Original 2-pass" an.
Um diese "alten" Einstellungen zu erreichen muss man in den Einstellungen unter Profiles "Choose your profile" DEAKTIVIEREN damit sich unter Bitrate Control "Original 2-pass" auswählen läßt. Anschließend läuft alles wie gehabt ;-)

DivX 5.03 released

Die Version 5.03 von DivX wurde released.
Die wichtigsten Punkte im Überblick:

Support for interlaced video in the decoder. Preserving the interlaced fields of interlaced video may sometimes result in better video quality during playback.

New de-ringing post-processing algorithm. The new algorithm improves the perceived video quality during playback. It is activated when the post-processing level is set to Level 6.

Video Buffer Verifier (VBV) model (one and two pass encoding). The VBV ensures that the maximum peak bit rate never exceeds either the user's inputted "maximum peak" bit rate value or/and ensures that the encoded stream never violates the buffer of an MPEG-4 compliant decoder. This helps to prevent decoding failure in both hardware and software where memory may be limited yet compliant to the MPEG-4 standard as defined in ISO/IEC 14496-2:2001(E). In order for DivX video to be successfully delivered over a restricted channel in real time to a decoder, the encoder's rate control must ensure that the decoder's buffer is not violated. When this is done properly, then overflow and underflow will never occur and the encoder is said to be "VBV compliant." It makes no difference whether the video is encoded in 1-pass or many, in real-time or offline. It is the encoder's rate control that must ensure compliance. There are three main requirements of a VBV-compliant rate control algorithm, in order of importance:

VBV compliance. When VBV parameters are specified (size, initial occupancy, channel characteristics) the rate control should avoid producing video that is in danger of violating the decoder's buffer. Bitstream stuffing may be used in extreme cases to prevent overflow in true CBR systems. Underflow must be prevented by increasing frame quantiser or by dropping frames.

Target bitrate. We aim to meet the user's requirements as accurately as possible here. This is directly related to filesize.

Good-looking video. Rate control should aim to produce the subjectively best quality video given other constraints. Consistency is important here as changes in quality are very noticeable and video is often judged by the worse quality segment in the whole sequence.

Nth Pass™ encoding. Another new addition to the rate control arsenal, Nth Pass™ encoding takes advantage of information available from previous analysis (or analyses) of the video sequence. Nth Pass encoding uses information garnered from previous passes through the video sequence, which can improve quality with each pass. There are four main steps to Nth Pass encoding:

Analysis (the first pass)

Map generation (where the results of analyses are processed)

Strategy generation (strategist examines map of the video sequence and creates a strategy that will best achieve the three VBV RC requirements)

In-loop nth pass rate control (uses information from the map and strategy to effect rate control that best fulfills the three requirements)

Support for DivX Certified Profiles. With the new DivX Certification program, DivXNetworks is enabling third parties to create "DivX Certified" products that are rigorously tested and fully compatible with the entire suite of DivX® video technologies. There are four levels of official DivX Certified video products: Handheld Video Devices, Portable Video Devices, Home Theater Video Devices and High Definition Video Devices. These levels quickly and clearly communicate what type and size of DivX video are supported on the certified device. Now, when you encode video, you have the option to force your video to comply with one of the DivX Certified Profiles to ensure that your video will play back properly on certified products.

DivX Decoder verification logo. There is a new semi-transparent DivX Logo that will appear by default for a few seconds any time you use the DivX decoder to watch a DivX video. This instantly lets you know you're watching a true DivX® video. You can turn the display of the logo on or off in the codec properties dialog.

New internal application programming interface (API). The internal API of the codec was changed to better accommodate integration with third party partners. This only affects you if you are a DivX licensee and are working directly with the DivX object code. The external API (e.g., DirectShow, etc.) remains unchanged.

The motion estimation algorithm is better optimized for High Definition resolutions (up to 1080p, or 1920 x 1080 pixel resolution

The pre-processing performance is now improved with with the IYUY 4:2:0 color space

Removed MP4creator and the MPEG-4 file output option due to some compliance issues. This will return in our next release once these issues are resolved.

Removed the Intelligent IVTC functionality due to persistent problems caused by lack of variable frame rate file format support. This technology will be back soon in a new form...

Changed the block skipping threshold for high quantizers, which improves visual quality when high quantizers are used.

Fixed a bunch of little cosmetic bugs in the DirectShow decoder properties page.

Fixed a bug where the last P frame before an I frame was not displayed when Smooth Playback was selected.

Fixed a practically unnoticeable YUV->RGB16 color conversion rounding bug.

Fixed a bug that was the cause of some of VirtualDub's "Cannot Start Video Compression" errors.

Fixed a few issues with DivX 3.11 compatibility.

Modified the decoder to deal with a bug in the old OpenDivX encoder that set the scalability bit incorrectly in certain cases. The DivX decoder can now detect this problem and play the content properly.

Fixed a problem where some rounding operations were not done toward zero, as is required by section 7.4 of the spec. This fixed an intra case in MPEG-2 inverse quantization.

Fixed a bug where some frames would be corrupted by an out-of-range error.

Fixed several rounding issues related to MMX/SSE/SSE2 optimizations.

Fixed an MMX bug in RGB32 color conversion.

Neue Version von TMPGEnc

Seit heute ist die Version 2.510 von TMPGEnc zum Download verfügbar.

Kurzzusammenfassung der Bugfixes zur Vorgängerversion:

Fixed: In the Environmental setting window, General tab, checking Enable multiplex with... and chosing

audio file other than mp1, mp2 or mp3 format would raise an error when starting to encode. 

Fixed: In the MPEG setting dialog window, GOP structure tab, when Detect Scene Change and Force picture

type setting were both selected, closing the dialog window and re-open it would clear the Force picture

type setting checkmark. 

Fixed: In the MPEG setting dialog window, System tab, chosing MPEG-1 Video-CD (non-standard) would in

fact select the MPEG-1 Video-CD setting.
