Compare the Handbrake compression rates. Likewise video encoders rely on sophisticated mathematical algorithms to decrease the size of videos while preserving their perceived quality. Lastly although certain techniques are shared among encoders, each one possesses unique attributes, and their efficiency varies.
Handbrake Compression Rates
Firstly among the HandBrake official Presets, x264 stands as the default video encoder. Secondly this encoder generates standard H.264/AVC video of exceptional quality with reasonable file sizes. Thirdly it also executes encoding relatively swiftly on modern computers. Foruthly the majority of contemporary mobile devices feature hardware decoders tailored for energy-efficient playback of H.264/AVC content. Lastly it can be argued that x264 is the most widely compatible contemporary video format. Likewise see also the DivX H.264 Decoder.
Video Presets
Likewise the x265 is a more recent video encoder, producing standard H.265/HEVC video. Note that this format gains prominence as modern mobile devices incorporate hardware decoders for energy-efficient playback. Likewise in scenarios like encoding in 4K Ultra High Definition or creating smaller, lower bitrate videos, x265 can yield equivalent or superior quality compared to x264, all within smaller file sizes. Lastly this comes at the expense of significantly slower encoding speeds.
Handbrake VP8 and VP9
Likewise there are alternate software video encoders like VP8 and VP9 offer outcomes similar to x264 and x265, but they generally demand longer encoding durations. Lastly an important consideration is that mobile devices with hardware decoders for VP8 and VP9 are not as widespread. Likewise potentially leading to accelerated battery consumption during video playback. Likewise in contrast, contemporary computers tend to handle VP8 and VP9 content with ease. Lastly see the VP9 Video Extension as well as the The VP8 Codec.
Hardware Encoders
Firstly HandBrake further includes support for hardware encoders such as AMD VCE, Intel QSV, and NVIDIA NVENC. Secondly these hardware-based encoders achieve exceedingly rapid H.264 and/or H.265 video encoding, albeit with some quality reduction and larger file sizes. Thirdly let’s engage in a comparative analysis. We’ve encoded identical high-quality 2160p 4K video sources to 1080p using eight distinct video encoders. Likewise also see the AAC ACM Codec on here.
Lastly ensuing outcomes were generated on a PC equipped with an Intel Xeon E5-2699 v4 CPU featuring 22 cores and 44 threads, operating at a consistent turbo speed between 2.6-2.8 GHz. Lastly the setup encompasses 32 GB of memory, an AMD Radeon RX 580, an NVIDIA GeForce GTX 1060, all orchestrated within a Windows 10 Professional environment.
Initiate the process by opening a video ‘Source’ within HandBrake. Proceed to encode the content utilizing each of the available ‘Presets’. Likewise pay careful attention to the encoding speed demonstrated by each ‘Preset’. In addition take note of the resultant file sizes that ensue. Likewise engage in the viewing of the encoded videos, employing visual assessment to gauge their quality. Note that deliberate on the inclusion of surround audio, especially if your original ‘Source’ incorporates such an audio track. Lastly, make a selection as to which ‘Preset’ aligns most effectively with your requirements. In addition opt for this chosen ‘Preset’ to serve as your go-to option for everyday encoding tasks.

Certain encoders exhibit a marked discrepancy in processing speed. Notably, hardware encoders outpace software counterparts by a significant margin, albeit with a trade-off involving diminished quality and/or increased file dimensions. Within this context, x264 emerges as the undisputed champion when it comes to striking the optimal equilibrium between swiftness, quality preservation, and file size containment. Lastly also see the x264 video codec on here.
