Every format below was worked out from real exports and tested against real jobs. Each converts to standard MP4 and comes with a certificate that lets the result be checked independently.

It is worth asking. New formats are usually a matter of days rather than months, and we would rather look at a real export than guess from a file extension. Send a sample — the whole export folder as the recorder wrote it — and we will tell you whether it can be converted. If it turns out not to play, the player it shipped with can help us make it work, and we will ask for it then.
There is no charge for that, and nothing is converted or billed until you say so.

Because then the pictures you rely on are not the pictures the recorder produced — they are a compressed copy, and every frame has been altered. Re-encoding also destroys the one thing that makes a conversion checkable: if the coded video is copied unchanged, its digest is the same either side, and anyone can verify that. If it is re-encoded, there is nothing to compare and you are asking people to take your word for it. So wherever the recording is in a standard codec — which is nearly always — it is copied, never re-encoded.
A few recorders store the picture in a proprietary codec that no standard player can open. Footage like that has to be decoded before it can be watched at all, so it is delivered as MP4 and certified a different way: the original file and the delivered file are each fixed by their own fingerprint, and every recorded frame is shown to have been carried across. Different proof, held to the same standard.
