![]() ![]() GPL-2.0-or-later with some libraries under LGPL-2.1-or-later VLC for iOS (MPLv2.0) Windows, ReactOS, macOS, Linux, Android, ChromeOS, iOS, iPadOS, tvOS, watchOS, Xbox system software The level-3 GPU Intel QSV, AMD, NVIDIA CUDA/NVENC hardware acceleration also makes it run 5X faster than HandBrake to avoid HB common issues like HandBrake freezing, crashing, taking forever converting files.GUI: C++ (with Qt), Objective-C (with Cocoa), Swift, Java It's well-designed with the unique "Auto Copy" mode to 1:1 copy streams without decoding and re-encoding and gives you the least quality loss (2%) on transcoding files by courtesy of default VBR quality setting and advanced High Quality Engine.īetter still, it trounces HandBrake with its page long input/output video formats, supporting MKV, MP4, MOV, AVI, FLV, WMV, HEVC, 3GP, YouTube, AAC, FLAC, MP3, etc. If you are strict with output video quality, try top HandBrake alternative WinX HD Video Converter Deluxe. Worse still, HandBrake produces lossy resulting file (even though you set CBR RF as 0), no truly 100% lossless conversion. ![]() Yet, HandBrake provides you with only constant bitrate and average bitrate, no variable bitrate option. Click here to see the detailed difference if you're interested. Need Variable Bitrate? Why Not Try HandBrake Alternatives?Īs is known to all, variable bitrate is much better than CBR and ABR, with quality and size perfectly balanced. Generally speaking, RF 20 is adequate for DVD and RF 22 is a good place to start when processing HD Blu-ray quality video. 2.7K/4K Ultra High Definition video: RF 22 - 28 is a suggested range.1080p Full High Definition video: RF 20- 24 is a suggested range.720p High Definition video: RF 19 - 23 is a suggested range.480p/576p Standard Definition video: RF 18 - 22 is a suggested range.Recommended constant quality settings (RF values) for H.264 (x264) and H.265 (x265) encoders: And we can't see any difference in quality between them. We once encoded a 43m8s episode with RF 0 and RF 20, and ended up with files in 6.1GB and 254.6MB respectively. This is because you'll end up with a video that is larger than the source file without any perceived difference in quality. So should we set RF to 0 to get the highest quality? No. RF 0 means badly slow encoding while lossless compression. RF 51 means fast encoding while extremely low quality. The lower the RF value, the higher the quality. HandBrake Best Constant Quality Settings for SD, HD, 4K, DVD, Blu-rayĬonstant quality RF value ranges from 51 to 0. HandBrake video settings control panel Part 2. This encoding mode is generally not recommended unless you aim for a specific file size.Īnother advantage of constant quality is that the encoding will be faster, because it encodes the file in one pass but produces the same quality as a 2-pass encoding. When you use average bitrate, you can estimate the file size via a calculator but lose control over the quality. ![]() That is to say, under constant quality based encoding mode you can control the output quality but can't control the file size, because the bitrate is variable.Ĭhoosing average bitrate means that you're telling HandBrake what bitrate you want. So, HandBrake will use different bitrate for different part of the video to achieve the given quality. HandBrake's Constant Quality (RF/CRF) vs Average Bitrate (kbps)Ĭhoosing constant quality means that you're telling HandBrake what quality level you want throughout your video.
