![]() ![]() ![]() None of the development team members own the devices, so testing was minimal and support was nonexistent. There are no more presets for the PSP, PS3, or Xbox 360. A single pass at a constant quality provides just as much compression efficiency as two passes at an average bitrate. Another result is that 2-pass encoding is not needed. 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. While this means output size is somewhat unpredictable, the results in picture quality speak for themselves. Overall quality improves, since bits are spent only when they are needed, and are saved when they are not. 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. No more looking for the perfect bitrate for a source-HandBrake is migrating to quality-based encoding. 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. For non-DVD sources, HandBrake now offers improved transport stream support, especially for high definition sources. As well, some bugs in underlying libraries have been patched. This means it can now read some DVDs it had trouble with before, and it can also select different angles on a DVD. HandBrake now uses a better DVD reading library called libdvdnav. 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.īetter input support, for DVD and non-DVD sources alike The preview window can show you still frames from your source, like always. The picture settings and preview sheet has been broken out into a filters and picture settings inspector, and a preview window. ![]() An added benefit is that multiple subtitle tracks can be included in the same output video.Įver wished you could test HandBrake settings before spending hours on a full encode? Now, you can. When using the Matroska container, you can also store the graphical subtitle images (VobSubs) from a DVD as a separate track. 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. 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). 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. 64-bit builds tend to perform approximately 10% better than their 32-bit brethren. 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. The end result? Better picture quality, at a smaller size, faster. But it has also gained new features like macroblock tree rate control and weighted P-Frame prediction. As always, it has been further hand-optimized for better performance. The past year, like every year, has seen some massive improvements for that video encoding engine. A large portion of these speed, size, and quality improvements come to us for free, from the x264 project. ![]()
