Follow

Problem summary
Creating a comp on a MOV, and rendering it to the timeline, results in the first frame being duplicated.
 
Customer reported version
Nuke Studio 13.2v4
 
Customer reported platform
macOS 11
 
Steps to reproduce
 
1) Open Nuke Studio.
 
2) Import a MOV file (File > Import File(s)...) and drop it on to the timeline. An example ProRes 422 file is attached.
 
3) Right click the clip on the timeline > Create Comp > Create Comp.
 
4) Right click the comp container on the timeline > Render Comp.
 
5) Scrub along the timeline and notice that the first frame on the comp container is duplicated.
Additionally, if you check the individual frames that are rendered to disk, the first two frames of the image sequence will be of the same frame.
 


 
Expected behaviour
The frames of rendered comp should match the original clip on the timeline, as well as in the Node Graph.
 
Actual behaviour
Creating a comp on a MOV, and rendering it to the timeline, results in the first frame being duplicated.
