Join shots with Duaer Video Concat
In Duaer, Duaer Video Concat joins shots rendered by Duaer Video Render into one MP4, in item order. It is free.
Join shots
- Have Duaer Video Render output one item per shot. The item order is the shot order in the final video.
- Connect Duaer Video Concat after it. Render ID defaults to {{ $json.renderId }}; you rarely need to change it.
- Select Execute step. All input items become one output item: the binary field data holds the MP4, plus a new renderId, duration in seconds, and shots.
Join 2 to 40 shots at a time, all with the same shape. Shots can be joined for 3 hours after rendering, and joining waits at most 15 minutes.
What Duaer Video Concat can join
Only renderIds returned by Duaer Video Render. Clips from Duaer Video have no renderId and cannot go straight into Duaer Video Concat.
The joined video has its own renderId, so you can pass it on to Duaer Video Music for background music.
