I’ve been having the same problem. I have found a workaround tough, even if it is longer than having the video ready just after the rendering process has finished.
I did this:
-These are my export settings
-As you see I use the Command Line Encoder, and I have ffmpeg installed to have it work correctly (look here for more information Export Formats | Unreal Engine Documentation).
- In Project Settings>Plugins>Movie Pipeline CLI Encoder I have set the Executable Path to the ffmpeg executable, and I changed the highlined settings.
- After this I render what I need, (to whoever may needs this) look for “Movie Render Queue” documentation to learn more about rendering (Movie Render Queue | Unreal Engine Documentation)
-
The result for me is a series of images (so I don’t now if I really need to export as ‘Command Line Encoder’, or if I could just export as ‘.jpg Sequence’…)
Still, I could not find a way to convert these images to movie file. My sister gave me an idea:
Use DaVinci Resolve to convert them into a video! (How to : Davinci Resolve PNG Image Sequence to Video - YouTube)
Be careful at which frame rate you export your render (you can change it in the ‘Output ’ setting), because in Davinci you should match the play frame rate speed of your sequence, you can do it by right clicking the sequence on the Edit workspace and do ‘Change Clip Speed ’ and set the one you rendered the image sequence with.
Hope it helps!
P.S: Also the cool stuff is that, if you need to change something and render again and you have selected the same directory of your previous rendered images, then Unreal will automatically overwrite the old images with the new render and woila, in Davinci Resolve the imported images will update automatically with the new ones.
