Code to create videos for recording sentence stimuli with standardised timings
There are two different types of videos that can be created here. One in which a vertical bar moves through the sentence, optionally changing colour at the beginning of each word ("moving bar"). Another in which a horizontal bar appears across the length of the sentence and fills with colour over time ("expanding bar"). Examples of the moving bar and expanding bar videos are provided.
The scripts were created and tested using MATLAB 2014b. No additional toolboxes are required.
To create moving bar videos for a list of sentences (that are specified in an Excel document), run AllSentenceMovies_MovingBar.m. The output directory (where the videos will be saved) and Excel file are both inputs to the script. The parameters in the first section of the script can be changed as desired, including the estimated time (in seconds) that the bar should take to move through the sentence.
The script calls createSentenceMovie_MovingBar.m, which can be used alone to create a video file of an individual sentence.
The file movieMaker_MovingBar.m will also need to be in the MATLAB path. The function of this script is to add a bar to an image.
To create expanding videos for a list of sentences (that are specified in an Excel document), run AllSentenceMovies_ExpandingBar.m. The output directory (where the videos will be saved) and Excel file are both inputs to the script. The parameters in the first section of the script can be changed as desired, including the estimated time (in seconds) that the bar should take to move through the sentence.
The script calls createSentenceMovie_ExpandingBar.m, which can be used alone to create a video file of an individual sentence.
The file movieMaker_ExpandingBar.m will also need to be in the MATLAB path. The function of this script is to add a bar to an image.
