Configuration¶

VBC can be configured via YAML files and CLI arguments. CLI arguments always override config file settings.

Configuration File¶

Default location: conf/vbc.yaml

Demo Configuration¶

Demo mode uses a separate simulation file: conf/demo.yaml.

uv run vbc --demo --demo-config conf/demo.yaml

This file controls simulated file counts, size distribution, processing speed, and error mix.

Configuration Reference¶

General Settings¶

`threads`¶

Type: Integer (>0)
Default: 1
Description: Maximum number of concurrent compression threads
Note: Runtime keyboard adjustment (</>) clamps to 1-8 threads
Implementation detail: Worker pool is created with max_workers=16, so practical upper parallelism is 16

Quality Defaults¶

Source: Encoder args (gpu_encoder/cpu_encoder) via -cq (GPU) or -crf (CPU)
Override: --quality CLI flag or general.dynamic_quality mappings
Recommendation ranges (0-63, lower = better quality):
35-38: Archival quality
40-45: High quality daily use
48-52: Good quality, smaller files
55+: Low quality, very small files

`prefetch_factor`¶

Type: Integer (>=1)
Default: 1
Description: Submit-on-demand queue multiplier. Higher values = more files queued.
Formula: max_queued = prefetch_factor × threads

`queue_sort`¶

Type: String
Default: name
Description: Processing order for files in the queue
Values: name, rand, dir, size, size-asc, size-desc, ext
Notes:
size is an alias for size-asc
rand can be made deterministic with queue_seed
ext uses the order of extensions and requires a non-empty list

`queue_seed`¶

Type: Integer or null
Default: null
Description: Seed for deterministic rand queue order
Example: 42 (ensure same random order across runs)

`log_path`¶

Type: String or null
Default: /tmp/vbc/compression.log
Description: Path to log file (overrides the output directory default)
Note: If set to null, logs are written to <output_dir>/compression.log.

`cpu_fallback`¶

Type: Boolean
Default: false
Description: Retry on CPU when GPU encoding fails with hardware capability errors
Note: Useful when NVENC runs out of sessions; pair with ffmpeg_cpu_threads
Behavior: HW cap .err markers are cleared on startup so files re-enter the queue

`ffmpeg_cpu_threads`¶

Type: Integer or null
Default: null
Description: Max CPU threads per ffmpeg worker when using CPU encoding (including fallback)
Note: Limits per-worker CPU usage; does not change threads (worker count)

`gpu`¶

Type: Boolean
Default: true
Description: Use GPU (NVENC) instead of CPU (SVT-AV1)
GPU (NVENC):
Pros: Very fast, good for 1080p/1440p
Cons: Quality ceiling at ~CQ35-38, session limits
CPU (SVT-AV1):
Pros: Excellent quality, no session limits
Cons: Much slower

`gpu_refresh_rate`¶

Type: Integer
Default: 5
Description: (Deprecated) Use gpu_config.sample_interval_s instead. Kept for backwards compatibility.
Note: See deprecation notice in GPU Monitoring section

GPU Monitoring (`gpu_config`)¶

Advanced settings for GPU monitoring sparklines.

`enabled`¶

Type: Boolean
Default: true
Description: Enable GPU monitoring and dashboard sparklines.
Note: Requires NVIDIA GPU and nvtop (VBC calls nvtop -s). nvidia-smi is only for driver checks.

`sample_interval_s`¶

Type: Float
Default: 5.0
Description: How often to sample GPU metrics (seconds).

`history_window_s`¶

Type: Float
Default: 300.0
Description: Total time window shown in sparklines (default 5 minutes).

`nvtop_device_index`¶

Type: Integer
Default: 0
Description: Index of the GPU to monitor when multiple GPUs are present.

`nvtop_device_name`¶

Type: String or null
Default: null
Description: Override device selection by name instead of index (e.g., "NVIDIA GeForce RTX 4090").
Note: When set, takes precedence over nvtop_device_index.

`nvtop_path`¶

Type: String or null
Default: null
Description: Custom path to nvtop binary (e.g., "/usr/local/bin/nvtop"). Auto-detected if not set.
Note: Useful when multiple nvtop versions are installed or nvtop is in a non-standard location.

`refresh_rate`¶

Type: Integer
Default: 5
Description: (Deprecated) Use sample_interval_s instead. Kept for backwards compatibility.

Deprecated Fields

gpu_config.refresh_rate is deprecated in favor of sample_interval_s
general.gpu_refresh_rate is deprecated in favor of gpu_config.sample_interval_s

For backwards compatibility, VBC still accepts both old fields, but new configurations should use gpu_config.sample_interval_s.

GPU Encoder (`gpu_encoder`)¶

Encoder args are full FFmpeg argument lists. VBC uses one list: common_args when advanced=false, otherwise advanced_args. Lists are not merged.

`advanced`¶

Type: Boolean
Default: false
Description: Use advanced_args instead of common_args.

`common_args`¶

Type: List of strings
Default: NVENC baseline (-c:v av1_nvenc, -preset p7, -tune hq, -b:v 0, -cq 45, -f mp4)
Description: Full FFmpeg arg list for standard GPU encoding.

Default: true
Description: When advanced=true, force output -pix_fmt to match the input (from ffprobe).

`advanced_args`¶

Type: List of strings
Default: AOM AV1 HQ set (-c:v libaom-av1, -crf 30, -cpu-used 0, -tune ssim, etc.)
Description: Full FFmpeg arg list for advanced CPU encoding (often outputs -f matroska, so .mkv).

UI Configuration (`ui`)¶

Input/Output¶

`input_dirs`¶

Type: List of objects ({path: string, enabled: bool})
Default: [] (empty)
Description: Ordered input directory entries used when no CLI input is provided
Behavior:
CLI input overrides config input (no merge)
Only entries with enabled: true are processed
UI order is exactly the same as YAML order
Duplicate path values are rejected (startup validation error)
Missing or inaccessible directories are skipped
Startup fails if no valid directories remain
Limits: max 50 enabled directories, max 150 characters per path

`output_dirs`¶

Type: List of strings
Default: [] (empty)
Description: Explicit output directories (one per enabled input directory, in order)
Rules:
Must exist and be writable
Count must match enabled input directories
Cannot be used with suffix_output_dirs (set it to null)

`suffix_output_dirs`¶

Type: String or null
Default: _out
Description: Output directory suffix appended to each input directory name
Notes:
Set to null when using output_dirs
Example: /videos → /videos_out

`errors_dirs`¶

Type: List of strings
Default: [] (empty)
Description: Explicit directories for failed files (one per enabled input directory, in order)
Rules:
Must exist and be writable
Count must match enabled input directories
Cannot be used with suffix_errors_dirs (set it to null)

`suffix_errors_dirs`¶

Type: String or null
Default: _err
Description: Suffix appended to each input directory name for failed files
Behavior: After processing, failed source files and their .err markers are moved here
Safety: If more than 100 .err files are found, VBC asks before moving them
Notes:
Set to null when using errors_dirs
Example: /videos → /videos_err

Metadata¶

`copy_metadata`¶

Type: Boolean
Default: true
Description: Copy EXIF/XMP/GPS tags from source to output
Method: Uses ExifTool to preserve all metadata including GPS

`use_exif`¶

Type: Boolean
Default: true
Description: Enable deep metadata analysis with ExifTool
Required for:
dynamic_quality (camera-specific quality)
filter_cameras (camera filtering)
GPS and camera model extraction

Filtering¶

`skip_av1`¶

Type: Boolean
Default: false
Description: Skip files already encoded in AV1 codec
Use case: Mixed libraries with some AV1 files already compressed

`filter_cameras`¶

Type: List of strings
Default: [] (empty = process all cameras)
Description: Only process files from specific camera models
Example: ["ILCE-7RM5", "DJI OsmoPocket3"]
Matching: Case-insensitive substring against extracted camera metadata; exact model strings are most reliable.

Quality Control¶

`dynamic_quality`¶

Type: Dictionary (string -> object)
Default: {} (empty)
Description: Camera model -> quality rule mapping.
Matching: Full-text search in all EXIF metadata

Example:

dynamic_quality:
  "ILCE-7RM5":
    cq: 38
    rate:
      bps: "0.8"
      minrate: "0.7"
      maxrate: "0.9"
      rate_target_max_bps: "95M"
  "Sony":
    cq: 40
  "DJI OsmoPocket3":
    cq: 45
    rate:
      bps: "180M"

Priority: First match wins (order matters in YAML)
Required schema: each entry must be an object with cq; legacy scalar format ("Sony": 40) is rejected.

`quality_mode`¶

Type: String
Default: cq
Values: cq, rate
Description:
cq: use encoder quality args (-cq on GPU, -crf on CPU)
rate: use bitrate target (bps) with optional minrate/maxrate
CLI validation rules:
--quality is valid only for quality_mode=cq
--bps / --minrate / --maxrate require quality_mode=rate

Type: String or null
Default: null
Description: Target bitrate for quality_mode=rate.
Accepted formats:
Absolute: 200000000, 200000k, 200M, 200Mbps
Relative: 0.8 (input bitrate × 0.8)

`minrate`¶

Type: String or null
Default: null
Description: Optional lower bitrate bound in rate mode.
Rule: Must use the same numeric class as bps (all absolute or all relative).

`maxrate`¶

Type: String or null
Default: null
Description: Optional upper bitrate bound in rate mode.
Rule: Must use the same numeric class as bps and minrate.

`rate_target_max_bps`¶

Type: String or null
Default: null
Description: Optional hard cap applied after bps/minrate/maxrate resolution in rate mode.
Accepted formats: Absolute only (95M, 100Mbps, 100000k, 100000000).
Scope:
Global: general.rate_target_max_bps
Per camera override: general.dynamic_quality.<pattern>.rate.rate_target_max_bps
Note: This caps target bitrate; it does not guarantee peak bitrate.

`min_compression_ratio`¶

Type: Float (0.0-1.0)
Default: 0.1 (10%)
Description: Minimum compression savings required
Behavior: If (1 - output_size/input_size) < threshold, keep original file instead of compressed version
Use case: Prevent "compression" that makes files larger

Error Handling¶

`clean_errors`¶

Type: Boolean
Default: false
Description: Remove existing .err markers on startup and retry those files
Behavior:
false: Skip files with .err markers
true: Delete .err files and retry compression

`verify_fail_action`¶

Type: String
Default: false
CLI: --verify-fail-action
Values:
false: disable output verification
log: mark job as failed and continue
pause: mark job as failed and pause queue with ERROR status (wait for R/S)
exit: mark job as failed and terminate processing with error
Verification checks (when mode is not false):
ffprobe can read output without errors
VBC tags exist: VBCOriginalName, VBCOriginalSize, VBCQuality, VBCOriginalBitrate, VBCEncoder, VBCFinishedAt

`repair_corrupted_flv`¶

Type: Boolean
Default: false
Description: Attempt to repair corrupted FLV files using FFmpeg
Behavior:
true: When a file fails processing and is moved to errors folder, attempts to repair it
false: No repair attempt

`wait_on_finish`¶

Type: Boolean
Default: false
CLI: --wait / --no-wait
Description: After all tasks complete, wait for user input instead of auto-exiting
Behavior:
true: Displays WAITING status; press R to restart scan or S/Ctrl+C to exit
false: VBC exits automatically when processing finishes

`bell_on_finish`¶

Type: Boolean
Default: false
CLI: --bell / --no-bell
Description: Play a terminal bell (BEL character) as a completion notification
Triggers:
When entering wait state (if wait_on_finish=true)
Just before exit (if wait_on_finish=false)
After FLV repair completes with at least one repaired file

UI/Display¶

`strip_unicode_display`¶

Type: Boolean
Default: true
Description: Replace non-ASCII characters (emoji, special Unicode) with '?' in UI
Reason: Prevents table alignment issues with emoji in filenames

`debug`¶

Type: Boolean
Default: false
Description: Enable verbose debug logging
Logs: FFmpeg timing, ExifTool calls, compression stages

`manual_rotation`¶

Type: Integer or null
Default: null
Values: null, 0, 90, 180, 270
Description: Global rotation override (takes precedence over autorotate)

Auto-Rotation¶

`patterns`¶

Type: Dictionary (regex -> angle)
Default: {}
Description: Filename regex patterns mapped to rotation angles

Example:

autorotate:
  patterns:
    "DJI_.*\\.MP4": 0        # No rotation for DJI drones
    "GOPR\\d+\\.MP4": 180    # 180° for GoPro pattern
    "IMG_\\d{4}\\.MOV": 90   # 90° for iPhone videos

Note: First match wins (order matters)

CLI Overrides¶

Only a subset of config keys can be overridden via CLI flags:

general.threads → --threads
encoder CQ/CRF value → --quality (only when quality_mode=cq)
general.quality_mode → --quality-mode
general.bps, general.minrate, general.maxrate → --bps, --minrate, --maxrate (only when quality_mode=rate)
general.gpu → --gpu/--cpu
general.queue_sort, general.queue_seed → --queue-sort, --queue-seed
general.log_path → --log-path
general.clean_errors → --clean-errors
general.verify_fail_action → --verify-fail-action
general.skip_av1 → --skip-av1
general.min_size_bytes → --min-size
general.min_compression_ratio → --min-ratio
general.filter_cameras → --camera
general.manual_rotation → --rotate-180
general.debug → --debug
general.wait_on_finish → --wait / --no-wait
general.bell_on_finish → --bell / --no-bell

Other settings (for example prefetch_factor, dynamic_quality, encoder arg lists, directory mappings, and gpu_config) must be set in YAML.

# Override threads and quality
uv run vbc /videos --threads 8 --quality 38

# Override GPU setting
uv run vbc /videos --cpu  # Force CPU mode

# Override camera filtering
uv run vbc /videos --camera "ILCE-7RM5,DJI"

# Override multiple settings
uv run vbc /videos \
  --config custom.yaml \
  --threads 8 \
  --quality 40 \
  --gpu \
  --skip-av1 \
  --clean-errors \
  --min-size 5242880 \
  --rotate-180 \
  --debug

Local Overrides (`VBC.YAML`)¶

VBC scans input directories for VBC.YAML and applies the nearest ancestor file per job.

Priority: Global config → Local VBC.YAML → CLI.

Allowed root keys: general, gpu_encoder, cpu_encoder, autorotate, cq.

Allowed general keys: gpu, cpu_fallback, ffmpeg_cpu_threads, copy_metadata, use_exif, filter_cameras, dynamic_quality, quality_mode, bps, minrate, maxrate, rate_target_max_bps, extensions, min_size_bytes, clean_errors, verify_fail_action, skip_av1, manual_rotation, min_compression_ratio, debug.

Special key: cq (int 0–63) overrides quality for both GPU and CPU encoder args.

Environment-Specific Configs¶

You can maintain multiple config files:

# Production (high quality, slow)
uv run vbc /videos --config conf/production.yaml

# Fast preview (low quality, fast)
uv run vbc /videos --config conf/preview.yaml

# Archival (maximum quality)
uv run vbc /videos --config conf/archive.yaml

Example conf/archive.yaml:

general:
  threads: 4
  gpu: false       # CPU for best quality
  copy_metadata: true
  use_exif: true
  min_compression_ratio: 0.05  # Must save at least 5%

cpu_encoder:
  common_args:
    - "-crf 30"    # Very high quality

Validation¶

VBC uses Pydantic for config validation. Invalid settings will raise errors on startup:

# Invalid threads (must be > 0)
Error: threads must be greater than 0

# Invalid rotation angle
Error: Invalid rotation angle 45. Must be 0, 90, 180, or 270.
