Technical Background Document: 3ivx D4 4.5.1

New Modules

3ivx DirectShow Video Encoder
* New DirectShow Video Encoder supports all the features of the VfW Encoder and more!
* Variable Frame Rate support, timestamps from original media are preserved
* Automatic PAR support. Automatically preserves media's DAR no matter what cropping or scaling is performed.
* DirectShow based means easy integration with any DirectShow application


New Features

Core
* Added support for an obscure MPEG-4 variant produced by some Digital Video Recorders

3ivx Video for Windows (VfW) Codec
* Encoding support for MPEG-4 PAR in AVI files.

3ivx DirectShow Video Decoder
* Decoding support for MPEG-4 PAR in AVI files.

3ivx DirectShow Media Muxer
* Muxing support for MPEG-4 PAR in AVI files.

3ivx DirectShow Media Splitter
* IChapterInfo support allows MP4 chapter lists to be used with many popular players.
* ChapterMarker support allows MP4 chapter lists to be used with other popular players.
* Support for AMR audio (as produced by some mobile phones). Note: 3ivx does not currently include an AMR audio decoder.

Win Installer
* M4A, MP4 and MOV are now registered as audio/video types with Windows Media Player
* M4A, MP4 and MOV can now be used in Windows Media Player's Media Library and Playlists.


Improvements

3ivx DirectShow Media Splitter
* Implements frame based seeking. It now works perfectly when the splitter is in "Frame accurate seeking"
* Fast seeking no longer causes frame stutter
* Large MP4/MOV files now open in seconds, rather than minutes.
* Uknown audio formats are not decoded as PCM

3ivx DirectShow Media Muxer
* Chunk buffer is now automatically enlarged if required.

3ivx DirectShow Audio Encoder
* Edit Text Fields were converted to Static Text
* VBR/ABR modes are now mutually exclusive
* FAAC was updated to 1.23.5

3ivx DirectShow Audio Decoder
* Audio Output buffer was enlarged, resulting in significantly less skips.

3ivx QuickTime Video Codec
* Now plays bitstreams which use a bpp of 12


Bugs Fixed

3ivx DirectShow Media Splitter
* Fixed crash when using frame based seeking
* Compaact AAC malformed MP4 files no longer crash the splitter
* PCM bug: "my video plays to fast and the audio is just noisy static"

3ivx DirectShow Media Muxer
* Fixed crash on large frame sizes, or >8mbps streams

3ivx DirectShow Audio Encoder
* Property Dialog's text fields no longer appear to have any effect

3ivx DirectShow Audio Decoder

Hi,

How's 3ivx compare to other codec (Divx and Xvid)?
Can they compare directly?

I've tried to compare Xvid and Divx, a little problem to compare because Xvid can't specify the bitrate in 2-pass encoding (or I miss that option?). I've try to produce both have nearest filesize. What Xvid (a version before RC1) have some strange color on screen, Divx no problem. But in return, the overall quality of Xvid was better.

Anyone did the 3ivx test already?

on high bitrates (2cd) its said to be comparable to xvid and divx5

on lower bitrates, which i use, its not comparable as it doesnt offers b-frames aso...

sure it can, you can switch between target size and target bitrate on the main option page

Notice that it is only 1 person's subjective view, educated, but still only subjective view of one.

Hopefully we will see in the future somekind of group testing with video too..
