HandBrake Description

HandBrake is a GPL'd multiplatform, multithreaded DVD to MPEG-4 ripper/converter. HandBrake application is a GPL'd multiplatform, multithreaded DVD to MPEG-4 ripper/converter. HandBrake was originally available on the BeOS, but now has been ported over to MacOS X and to GNU/Linux. Here are some key features of "HandBrake": Supported sources: · Any DVD-like source: VIDEO_TS folder, DVD image or real DVD (even encrypted) · PAL or NTSC · AC-3, LPCM or MPEG audio tracks Outputs: · File format: MP4, AVI or OGM · Video: MPEG-4 or H.264 (1 or 2 passes or constant quantizer encoding) · Audio: AAC, MP3, Vorbis or AC-3 pass-through (supports encoding of several audio tracks) · Misc features · Chapter selection · Basic subtitle support (burned into the picture) · Integrated bitrate calculator · Picture deinterlacing, cropping and scaling · Grayscale encoding Requirements: · liba52 (AC3 decoding) · libavcodec (picture cropping, scaling and deinterlacing, MPEG-4 encoding) · libdvdcss (CSS decryption) · libdvdread (DVD navigation) · libfaac (AAC encoding) · libmp3lame (MP3 encoding) · libmp4v2 (MP4 muxing) · libmpeg2 (MPEG-2 decoding) · libogg (OGM muxing) · libsamplerate (audio resampling) · libvorbis (Vorbis encoding) · libx264 (H264 encoding) · libxvidcore (MPEG-4 encoding) What's New in This Release: · x264 · A large portion of these speed, size, and quality improvements come to us for free, from the x264 project. The past year, like every year, has seen some massive improvements for that video encoding engine. As always, it has been further hand-optimized for better performance. But it has also gained new features like macroblock tree rate control and weighted P-Frame prediction. The end result? Better picture quality, at a smaller size, faster. · So, if x264 alone gives us smaller, better, faster encodes...what have HandBrake's developers been doing over the past year? · Oh, all sorts of things! · New build system · HandBrake has a new, much improved compilation system, which allows easy 64-bit and parallel builds, as well as providing easy extendability for future improvements to the application. 64-bit builds tend to perform approximately 10% better than their 32-bit brethren. There is no Snow Leopard magic here: the performance gains can also be realized on Intel Macs running 10.5, as well as Linux systems. · Soft subtitles · HandBrake can now include subtitle tracks that can be turned on and off, instead of rendering them onto the video track permanently (which also reduces video compression). This means you can include Closed Captioning data from DVDs and TV broadcasts, or find SRT text subtitle files on the 'net and include them. When using the Matroska container, you can also store the graphical subtitle images (VobSubs) from a DVD as a separate track. An added benefit is that multiple subtitle tracks can be included in the same output video. · Live preview · Ever wished you could test HandBrake settings before spending hours on a full encode? Now, you can. · The picture settings and preview sheet has been broken out into a filters and picture settings inspector, and a preview window. The preview window can show you still frames from your source, like always. But it also lets you start to encode a short clip from the current preview with the currently selected settings, and view the results right there inside of HandBrake. · Better input support, for DVD and non-DVD sources alike · HandBrake now uses a better DVD reading library called libdvdnav. This means it can now read some DVDs it had trouble with before, and it can also select different angles on a DVD. As well, some bugs in underlying libraries have been patched. · For non-DVD sources, HandBrake now offers improved transport stream support, especially for high definition sources. A number of decoding bugs have been resolved as well, so Windows users will no longer need fear AAC audio, nor Mac users fear VC-1 video. · Constant quality encoding · No more looking for the perfect bitrate for a source--HandBrake is migrating to quality-based encoding. This means that instead of telling encoders to use a specific size and vary quality to meet it, we tell the encoder to vary size to meet a given quality level. Overall quality improves, since bits are spent only when they are needed, and are saved when they are not. While this means output size is somewhat unpredictable, the results in picture quality speak for themselves. · As part of this change, the quality slider has been made more prominent, and now works off the quality values used by the video encoders, instead of a confusing, custom, percentage scale. · Another result is that 2-pass encoding is not needed. A single pass at a constant quality provides just as much compression efficiency as two passes at an average bitrate.
