Rendering only missing frames on animation I'm rendering an animation in blender as image files and I wanted to render some parts of it first, just so I can see these particular parts first.
Also, some parts of the animation, I rendered jumping a few frames (with the frames step config set to 3).

Is there a way to easily render only the missing frames? Maybe by making blender read the image files names and identifying the missing ones.

And I wanted to know aswell if there is a way to insert the rendered frames in the video editor but with the "right position". For example, I rendered frames 1, 3 and 5. As I insert it on the editor, the frames 2 and 4 would be blank, but my video would still have 5 frames.

Thanks in advance!
In the Render Settings under Output you will find the overwrite option will do what you want.


  Overwrite - Overwrite existing files when rendering.


What that means is that when overwrite is disabled and blender goes to render frame 12 and the file for frame 12 already exists it will not render that frame and go onto the next one.

For the VSE, if a bad (or empty) file exists for a frame when you add the image sequence to the VSE it will read the updated file for the bad frame/s once you have rendered them.
