Can't be changed. And it's best when used with alerts, not hour long clips.Looking for where you can set the FF speed in the preview pane for stored clips. When you hover your mouse over the clip preview image it'll fast forward super fast but can give you an idea of what transpired during the clip...but don't blink, LOL. The default must be 1000x speed.

On clips it seems like it more like skips every 8 minutes instead of frames. For the alerts it works fine with every 8 frames. It'd be a sweet feature if on the clips you could select the speed as sometimes things occur that you didn't necessarily want to trigger an alert but want to check to see if someone was walking down the street during the clip.That isn't a set speed really, it just gives you 8 frames evenly spaced through the alert/clip, then repeats.
I think I was asking for something else. I'll double click the 1hour clip to pull up the full view and just select the xSpeed as usual. Just thought it'd be a nice touch to use this same technique with long clip previews...alerts is fine but clips it's typically not helpful to me how I was hopeful it could be used.It does not display every 8th frame. It shows you 8 frames, evenly spaced across the duration of the clip or alert item. For a 60 minute clip, the 8 preview frames will be at these timestamps:
1. 0s
2. 7m30s
3. 15m
4. 22m30s
5. 30m
6. 37m30s
7. 45m
8. 52m30s
And then it loops back to the start. It tries to load each frame 200ms after the previous one so you get a preview frame rate of (up to) 5 FPS, and it only takes about 1.6 seconds to complete a loop.
Imagine you were to make this preview show a frame every 2 seconds instead. Now it takes 6 minutes to preview a 1 hour clip (or longer, if Blue Iris can't keep up with the 5 FPS preview rate).
