H.265

What this is about

The efficiency gain is real and matters most where bandwidth is expensive: 4K streaming, HDR delivery and long recordings on small cards. The catch is that the same efficiency comes from more complex analysis, so decoding needs newer hardware and encoding takes longer. Older browsers and editing setups may refuse the file outright, and its licensing situation is more tangled than H.264's. For a client review link, H.264 remains the safer choice; for a 4K master to a streaming platform, H.265 is often what the spec asks for.

A term only helps when everyone on set means the same thing by it — so what follows is how it is used, not a dictionary definition.

What runs differently here

In planning terms, that means:

• Roughly the same picture at a lower bitrate — the reason 4K and HDR delivery moved to it
• Encoding and decoding cost more; older machines and browsers may not handle the file
• For client review links stay with H.264, where compatibility beats file size

With TillyGen

Delivery formats recorded per project in TillyGen keep the final export aligned with what the platform demands rather than with a habit.

Change one constraint and the consequences travel through the whole plan: affected shots are flagged, the call sheet is regenerated, and nobody keeps working from yesterday's version.
