Correction of video 11

Due to an issue in the video file “Video_11.mp4”, the annotations (segmentation masks, keypoints, phases) from frame number 48800 to the end of the video were shifted/misplaced and did not match the corresponding frames.
We have therefore updated the archive “Video_11.zip”, which now contains the correct video file “Video_11.mp4”, so that the images from frame number 48800 onwards can be recreated to match the annotations.
The annotations for the three tasks remain unchanged, the issue only affected the video file.
