Rough-Cut Multi-Hour Livestream Recordings in 3 Seconds Without Re-Encoding using LosslessCut + Whisper
Cutting a 5-minute highlight from a 3-hour 4K livestream in Premiere takes 20 minutes to render. Pair Whisper transcripts with open-source LosslessCut to slice segments via direct stream copy in 3 seconds with zero quality loss.
BEST FOR
Livestream clippers, educators, YouTubers, video editors and DITs
REQUIREMENTS
Windows, macOS or Linux PC; open-source LosslessCut
✦ WHY THIS WORKFLOW
Traditional NLEs decode and re-compress every frame just to trim a file. LosslessCut copies the underlying bitstream directly, turning a 30-minute render queue into a 3-second file operation.
Below is an SRT transcript from a 2-hour recording.
Select the **8 best viral highlight segments (45s–180s each)** and output them strictly as a **LosslessCut-compatible CSV** (no header, exact format per line: `HH:MM:SS.mmm,HH:MM:SS.mmm,Short_Clip_Title`):
1) Start each cut right on the hook question and end cleanly after the takeaway;
2) Keep labels filesystem-safe.
