Buffer setting for SD and HD camera to get same clip time

[trumee]

I have a SD camera running at 5fps linked to an HD camera streaming at 15fps. I noticed that the recording time is different for the two camera. Documentation seems to suggest that i can use Pre/Post Event Image Buffer.

If i use 5 frames for the SD camera,


How many frames do i need for the HD to get the same total time?

PS: Pre 10 and Post 20 frames seems to not work.

The FPS is 3x, so the buffers would need to be 3x.
