Problem memory to export video from simulink to workspace

Hello,

I am trying to export a video from simulink to Matlab workspace with the block "To workspace". However, I got an error due to the limited RAM regarding the video features. Is there any tip to refresh the memory during the exportation?

The message error is:

Cannot create variable 'image' in workspace
Error due to multiple causes.
Data logging exceeded available memory
Cannot allocate sufficient memory for logging. Consider disabling logging or reducing the length of the simulation

Thank you in advance,

Pm

What resolution are you saving at? RGB or grayscale? How many frames per second, and how many seconds?

I export with a resolution of 640x480 in grayscale at 30 fps during 120 secondes. Thanks, Pm

No idea?
