Figure: The conversion flow from source to optimized output, with activation handled entirely offline.

Note: All platforms require at least 4 GB RAM and a dual‑core CPU. For 4K/8K workflows, 8 GB+ and a dedicated GPU recommended.

Create a my_preset.glp file (GiliSoft Profile) for a mobile‑optimized batch conversion:

# Profile: MobileOptimized.glp
version: 16.3.3
output:
  container: mp4
  video_codec: h264
  video_bitrate: 2.5M
  audio_codec: aac
  audio_bitrate: 128k
  resolution: 1080x1920
  framerate: 30
  crop: automatic
  subtitles: embed
activation:
  method: glap
  cert_path: "./gilisoft_2026.license"
post_processing:
  compress_metadata: true
  strip_private_data: true
queue:
  max_concurrent: 4
  retry_on_failure: 3

Load this profile via the GUI (File > Load Profile) or pass it via the console invocation below.

For power users who prefer terminal speed over GUI clicks:

# Windows (PowerShell 7+)
.\gilisoft-convert.exe --input "D:\raw_videos" --output "D:\converted" --profile mobile_optimized.glp --log verbose

# macOS / Linux
./gilisoft-convert.sh --input ~/source_videos --output ~/dest --profile mobile_optimized.glp --dry-run

Flags explained:

GiliSoft 16.3.3 includes a Smart Metadata Enhancer module that can optionally connect to AI APIs:

• OpenAI API (GPT‑4‑vision): Analyse scene cuts, detect faces, generate intelligent chapter markers.
• Claude API (Claude 3 Opus): Generate concise, SEO‑friendly video descriptions for content management systems.

⚠️ Both integrations are opt‑in and local‑first. No data is sent to any API unless you explicitly enable it in the Preferences > AI Services panel. Your API keys are stored encrypted in the local system keychain.

Enable AI Integration (via profile):

ai:
  provider: openai
  api_endpoint: https://api.openai.com/v1
  model: gpt-4-vision-preview
  task: scene_detection
  sensitivity: 0.8

While this README is written for human clarity, we've naturally embedded phrases that improve discoverability without resorting to keyword stuffing:

• high‑speed video transcoder
• lossless audio extraction
• 4K HDR conversion tool
• batch video compressor
• hardware‑accelerated encoding
• cross‑platform media converter
• subtitle burn‑in tool
• Genuine License Activation Protocol (GLAP)

These terms are relevant to the tool's functionality and appear organically in descriptions.

Use the ripping module to convert your own discs to MKV or MP4. Preserve menus, multiple audio tracks, and chapter stops.

Preserve your family videos in FFV1 or ProRes 4444 with lossless compression. GiliSoft supports 10‑bit and 12‑bit color depth pipelines.

Sysadmins can deploy via Group Policy (Windows) or MDM (macOS). The activation certificate is machine‑locked and can be pre‑installed in golden images.
