# Audio/video formats

The particular set of Audio/video formats that you can use can depend on the version of the underlying encoding tools that Transloadit uses for the following Robots:

Transloadit recommends having: `ffmpeg_stack: "v7.0.0"` in these Robots’ Assembly Instructions. We are intimately aware of how important continuity is for our customers, so stack version upgrades are always opt-in. Stack versions are typically supported for many years before we start issuing deprecation warnings (for example, we had been supporting `"v1.0.0"` for 11 years before we deprecated it).
