Frame-accurate utilities for post-production.

Timecode, retime, storage and aspect maths that agrees with your NLE — plus delivery specs you can actually trust.

Five tools

TimecodeAdd, subtract, and solve in → out across every frame rate, drop and non-drop.
Conform & speed changeWhat a retime does to your runtime, and when a rate change needs motion compensation instead.
Storage & data rateHow big the media will be, and how much runtime fits on the drive you have.
Aspect & scalingFit, solve and reduce any frame size to its simplest ratio.
Delivery specsBroadcaster and platform requirements, grouped and searchable.

On the specs

Every entry is read from the source document, and dated.

Delivery specs circulate as screenshots, forum posts and half-remembered numbers, and they go out of date quietly. ARTE replaced its entire technical guide in 2026. ATSC A/85 was revised this year for the first time since 2013. Plenty of people are still working from the old ones.

So every entry in Runtrue carries the document it came from, that document’s version, and the date it was last checked verified 2026‑08‑01. Nothing is included on the strength of memory. Where a broadcaster asks that their document not be redistributed, Runtrue points to the source instead of reproducing it.

Spec data updates over the air, so a correction reaches you without waiting for an app update.
