HandBrake

HandBrake is a popular open source, cross-platform video transcoding tool. It can efficiently convert video files in almost all common formats into universal formats suitable for mobile phones, tablets, game consoles and various playback devices. The software interface is intuitive and provides a wealth of preset parameter options, allowing users to flexibly control file size while ensuring output quality. It is a powerful assistant for daily video format conversion and compression processing. Friends who like HandBrake, come to Huajun Software Park to download and experience it!

HandBrake Highlights

Cross-platform support

Compatible with Windows, macOS and Linux systems, users can use it seamlessly on different devices.

Supports Docker deployment and can run on high-performance servers such as NAS.

Preset templates and custom options

Provide device preset configuration files (such as iPhone, Android, Apple TV) to quickly generate compatible formats.

Supports customizing parameters such as resolution, frame rate, bit rate, encoder, etc. to meet professional needs.

Video filters and optimization

Built-in deinterlacing, noise reduction, image cropping, scaling adjustment and other filters can optimize old videos or remove black borders.

Supports NTSC/PAL format parameter adjustment to adapt to different regional standards.

Subtitles and Chapter Management

Allows adding, removing or embedding subtitles, supporting closed subtitles (CEA-608) and external subtitles (.srt).

Keep video chapter information for easy jump viewing.

HandBrake Features

Hardware acceleration support

Supports hardware acceleration technologies such as Intel Quick Sync Video (QSV), NVIDIA NVENC, and AMD VCE, significantly improving conversion speed.

Flexible coding modes

Provides constant quality (CRF) and average bit rate (CBR) control modes:

CRF mode: Recommended value is 20-23. The smaller the value, the higher the image quality (the larger the file size).

CBR mode: You can manually set the target bit rate (such as 1500 kbps), suitable for scenarios with strict volume requirements.

Based on FFmpeg framework

Inheriting the powerful decoding capabilities of FFmpeg, it supports all its video formats to ensure compatibility.

HandBrake function

Format conversion and compression

Supports input of almost all mainstream video formats (such as AVI, MOV, MPEG, TS, MKV, MP4, etc.) and outputs standard formats such as MP4, MKV, WebM, etc.

Provides efficient video compression capabilities that can compress high-definition videos (such as 4K) into lightweight files suitable for network transmission while maintaining image quality.

Multi-track audio and video encoding

Integrate mainstream video encoders such as x264 (H.264), x265 (H.265), VP8/VP9, AV1, etc., and support audio encoding formats such as AAC, FLAC, AC3, and Opus.

Multiple audio tracks (such as multi-language dubbing) and third-party subtitle files (VobSub, SRT) are allowed to be retained, but the ASS/SSA subtitle format is not currently supported.

Batch processing and queue management

Supports adding multiple video files to the transcoding queue at the same time. Different parameters can be set for each file to achieve batch conversion.

Provides chapter mark segmentation function to facilitate the management of long videos.

HandBrake FAQ

Image quality deteriorates/blurs after transcoding

Reason:

Improper encoder selection (e.g. H.264 code rate is too low).

The CRF value is set too high (the larger the value, the worse the image quality).

Resolution forced scaling results in loss of detail.

Solution:

Adjust the CRF value: H.264 recommends 18-22, H.265 recommends 20-24 (the smaller the value, the higher the image quality).

Use constant quality mode: avoid average bit rate (CBR) over-compression.

Turn off scaling: Select Same as Source in the Dimensions tab.

Enable filter optimizations such as Sharpen or Denoise to balance image quality and noise.
