Cut step causes "Not Responding" or freeze on click, even for short clips

[d1vyo]

Clicking "Cut" on a clip candidate immediately freezes the app Windows
title bar shows "AutoShorts (Not Responding)" right from the start of
the click not after a delay
Steps to reproduce:

1. Import a long source video (71 minutes)
2. Run Transcribe + Find Viral Moments (used Ollama/Qwen 2.5 7B locally)
3. Select a clip candidate and click "Cut"
4. App immediately shows "Not Responding" in the title bar
   Observed:

• Task Manager shows ffmpeg.exe running with active CPU (15-17%) so
  it's not fully dead but the UI is completely unresponsive from the
  moment Cut is clicked
• Tested with two different short clip candidates (20s and 8s) both
  from timestamps near the 69-71 minute mark of a 71-minute source file.
• Suspect ffmpeg may be seeking/decoding from the start of the source
  file rather than jumping directly to the clip timestamp, which would
  explain why cut time doesn't match the short output clip length.

Environment:

• Windows 11
• RTX 4050, i5 13th gen, 32GB RAM
• LLM engine: Ollama (Qwen 2.5 7B), local Whisper for transcription
• Source video: 71 min MP4

Thanks for looking into it! I'd rather not run a random .zip though could you share the actual fix as a code snippet or a PR instead?
Even just which file/line you changed would help. Appreciate you taking the time either way.
