Video Codecs

The particular set of Video Codecs 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: "v4.3.1" 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).

Audio / Video Filters

The particular set of Audio / Video Filters 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: "v4.3.1" 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).

Name Description ffmpeg_stack
