PsychoPy version (e.g. 2023.2.3):
What are you trying to achieve?:

Hello everyone,

I’m looking to display videos and manipulate their playback speed during the presentation. I’ve created a “speed” column in my Excel file, where a value of 1 corresponds to the normal speed of the video. I also have other values, such as 1.2 for 20% faster playback and 0.8 for slower playback. However, I can’t seem to find the relevant function in the PsychoPy manual that would allow me to adjust the video speed, nor can I determine how to implement it in my routine using the code component.

Any suggestions or guidance would be greatly appreciated!

Thank you, Sarah

Dear Sarah,

I am not sure if psychopy can easily manipulate the playback speed of videos. However, an easy solution would be to make multiple versions of the same video with different playback speeds.
