Episode notes
Automate Editing From Transcripts
- Use automated tooling to turn transcripts into editable video timelines to avoid manual editing.
- Run editing commands on a powerful remote machine to handle large files and limited local resources.
Building A DSL To Edit The Podcast
- Buck and Claude processed the podcast by transcribing with Deepgram and assigning IDs to each line for easy rearrangement.
- They compiled a DSL to ffmpeg commands and executed them to produce the final cuts, with one manual intro edit.
Mix Automated Cuts With Manual Touchups
- Generate automatic shot cuts using heuristics to speed editing while accepting imperfect results.
- Reserve manual editing for parts that need higher polish, like intros or key segments.
