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.

doc_batch

doc_batch_desc

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

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.
