使用预设

为您的使用场景选择合适的预设：家庭视频、内容创作、监控录像或最大节省。

手机存档	H.265	23	Home videos from phones	40-50%
YouTube Raw	H.265	20	Content creators	30-40%
安防存档	H.265	28	Surveillance footage	50-60%
婚礼存档	H.265	18	Wedding videographers	25-35%
最大节省	AV1	35	Maximum compression	55-70%
快速H.264	H.264	23	Fast, broad compatibility	20-30%
Web优化	VP9	30	Web content	45-55%

手动配置

精细调整编解码器、CRF、音频、字幕和硬件加速设置以获得完全控制。

Codec Selection

Choose between H.264 (widest compatibility), H.265/HEVC (best balance of quality and size), AV1 (highest compression efficiency), or VP9 (open-source, web-friendly). Each codec offers different tradeoffs between encoding speed, file size, and playback compatibility.

CRF Slider

The Constant Rate Factor (CRF) controls quality. Lower values mean higher quality and larger files. Typical ranges: 18-23 for high quality, 24-28 for balanced, 29-35 for aggressive compression. The slider provides real-time estimated savings.

Audio Options

Audio streams can be copied as-is (fastest, no quality loss) or re-encoded. Copying is recommended unless you need to reduce audio bitrate or change the audio codec.

Subtitle Handling

Subtitle streams are preserved by default during recompression. Text-based subtitles (SRT, ASS) are copied directly. Bitmap subtitles (PGS, VobSub) are handled according to the output container format.

Output Directory

Choose where recompressed files are saved. By default, output files are placed in a subfolder next to the originals. You can also specify a custom output directory for all processed files.

批量处理

添加文件夹、配置工作线程数，让队列一夜之间处理您的整个视频库。

Multi-Worker Queue

The application processes multiple videos simultaneously using a worker queue. Software encoding defaults to 1-2 workers (since FFmpeg itself uses multiple CPU cores). Hardware encoding supports 2-3 concurrent workers for maximum GPU utilization.

Pause, Resume, and Cancel

You can pause the entire queue at any time and resume later. Individual jobs can be cancelled without affecting the rest of the queue. Pausing does not corrupt partially encoded files.

Progress Tracking

Each file shows a real-time progress bar based on frame count. The dashboard provides an overview of total progress, estimated time remaining, and cumulative space savings across the entire batch.

Hardware Acceleration

自动检测并使用GPU进行超快编码。如果没有兼容硬件则回退到软件编码。

GPU Vendor	Technology	H.264	H.265	AV1	VP9
NVIDIA	NVENC	h264_nvenc	hevc_nvenc	av1_nvenc	—
Intel	QSV	h264_qsv	hevc_qsv	av1_qsv	vp9_qsv
AMD	AMF	h264_amf	hevc_amf	av1_amf	—

Automatic Fallback

If hardware encoding fails or is unavailable, the application automatically retries with the corresponding software encoder (libx264, libx265, libsvtav1, or libvpx-vp9). This happens transparently — you never see the failure. Every file completes regardless of GPU availability.

命令行界面

使用CLI工具从脚本、计划任务或CI/CD流水线自动化视频重新压缩。

Basic Usage

VideoRecompressStudio.CLI --input <directory> --preset phone_archive --output <directory>

Available Options

Option	Description
`--input <path>`	Input directory to scan for video files (recursive)
`--output <path>`	Output directory for recompressed files
`--preset <name>`	Use a built-in preset: phone_archive, youtube_raw, security_archive, wedding_archive, max_savings, quick_h264, web_optimized
`--codec <codec>`	Video codec: h264, h265, av1, vp9
`--crf <value>`	CRF quality value (0-51, lower = higher quality)
`--workers <n>`	Number of concurrent encoding workers
`--help`	Display all available options

Examples

# Compress home videos with the Phone Archive preset
VideoRecompressStudio.CLI --input "D:\Videos\Phone" --preset phone_archive --output "D:\Videos\Compressed"

# Use AV1 with custom CRF for maximum savings
VideoRecompressStudio.CLI --input "E:\SecurityCam" --codec av1 --crf 32 --output "E:\Archive"

# Process with 3 hardware-accelerated workers
VideoRecompressStudio.CLI --input "D:\Projects" --preset youtube_raw --workers 3 --output "D:\Encoded"
