Swap dimensions Help
Intro This operation results in a movie that shows the temporal development of video lines.
For example, the first frame of a horizontal swap shows the temporal development of the first vertical video line at the left.
Each frame is like a photo-finish picture.
Sometimes parts of the result movie look very nice and/or intriguing.
You can use this feature to study temporal noise correlations. Also the behavior of edge lines can be interesting. You can see which lines need to be cropped by looking at the first few and last few frames of the swapped movie.
Scene changes show up immediately.
Longer movies are transformed to chapters. Each chapter corresponds to a swapped part of the input movie. For example, if you swap an HDV movie horizontally then the first 1080 frames (36 seconds for a 30f/sec movie) correspond to the first chapter.
For a nice effect you don't want scene changes in a chapter.Horizontal Choose "horizontal" to view the temporal development of vertical lines in one frame.
Choose "vertical" to view the temporal development of horizontal lines in one frame.More info The result movie is usually a little longer than the original and the last part usually has a black bar at the bottom or a black pillar at the right. This doesn't happen if the number of frames in the input movie equals a multiple of the height (vertical) or width (horizontal).
This operation may use a huge amount of memory. The worst scenario would be horizontal swap of a 1920x1080 movie (square pixel). In this case the memory needed equals 2*width*width*height = 7.4 GB. If this is close to or more than your RAM size the virtual memory system may need to swap data to disk and the whole process becomes slow.
Troubleshooting No preview is shown because this type of converson is very complex.
This conversion is slow for HD movies. The progress bar only starts to move after a delay.
If you get the message "Out of memory" restart the application and try again.
