ISO Recording

What is it?

ISO ("isolated") recording means saving each source as its own separate file in addition to the mixed show: one file per camera, one per guest, one per screen share — each clean and complete, regardless of what was actually on screen at any moment. The live broadcast is the director's mix; the ISOs are the raw ingredients, preserved individually.

Practical example

A host records a podcast live with two remote guests. The live mix shows whoever was spotlighted at each moment. Afterward, the editor opens the ISO files: the host's full track, guest A's full track, guest B's full track — every person, the entire session, even the minutes they weren't on screen. Now the editor can re-cut the conversation properly: show guest B's priceless facial reaction that the live switcher missed, fix a moment where the wrong person was on screen, and master each voice separately. Riverside and SquadCast built their reputations on exactly this — the live show is a draft; the ISOs make the polished episode possible.

Key things to know (non-technical)

• ISOs are what separate "we streamed it" from "we produced it" — post-production quality depends entirely on having them.
• Audio ISOs matter even more than video: per-person audio tracks allow individual cleanup, leveling, and noise removal.
• The cost is storage: a 4-person show generates 5+ full-length files — which is why ISO recording is typically a paid-tier feature.
• The buyers are podcasters, shows with editors, and anyone repurposing content seriously.

In Tupic Live

ISO recording — separate clean files per participant alongside the live mix — is Tupic Live's bridge to the podcast and professional-show market: the live broadcast becomes simultaneously a finished product and a recording session, one show yielding both.
