↓ Watch what comes out
A LinkedIn Live recording is almost always mono mixed-down audio with 2-4 guests. We diarize acoustically, keep the timecodes aligned with the original MP4, and ship SRT so you can re-upload with proper captions.
So the hook on a LinkedIn post — first two lines have to earn the 'see more' click.
Right, and most people waste it on a greeting. 'Excited to share' is dead on arrival.
What's working for you right now — short carousel posts, or video?
Native video, under 90 seconds, captions burned in. Reach is roughly 3x our text posts.
↓ This is the dashboard
Same layout as the real dashboard — Summary, full Transcript, Speakers tab, Exports. Key points and action items extracted automatically. Auto-tags on every job.
Sample preview from a founder interview about post-call workflow. Real transcripts look exactly like this — same tabs, same summary block, same key-points / action-items split, same auto-tag chips.
Three real options · honest comparison
LinkedIn burns its own captions into video player on upload. Submagic and Opus Clip turn long LinkedIn videos into vertical short clips with captions. We do the transcript layer — clean text, SRT, speaker labels — so you can feed any of those downstream tools or repurpose by hand.
Free, baked into the LinkedIn player. No export, English-leaning, no speaker labels.

Turns long LinkedIn video into vertical short clips with stylized burned-in captions.
Pricing and feature availability approximate as of 2026. LinkedIn caption language list varies by region.
Specific to LinkedIn
LinkedIn re-encodes audio aggressively and locks private posts behind auth. A couple of habits fix both.
Drop a LinkedIn URL or MP4 and these flip on by default. Override per-job from the form.
Accuracy · real-world numbers
LinkedIn re-encodes everything on upload, so audio bitrate is usually 96 kbps AAC mono regardless of what you uploaded. What separates a clean transcript from a messy one is the original microphone, not the LinkedIn pipeline. Numbers below come from actual customer LinkedIn files.
Single speaker, recorded in OBS or Riverside, then uploaded. Clean low-noise audio — most thought-leadership posts land here.
Streamed via Restream, StreamYard, or LinkedIn's native Live. Mono mixdown, but speakers usually have distinct voices and decent mics.
Outdoor or office ambient noise, built-in mic. Words usable, occasional misses on proper nouns and brand names — paste those into custom vocabulary.
Multiple panelists on different mic qualities, intro music, slide-change audio. Plan a rename pass on the speaker chips.
