Hi Al.

So you are getting one and a half frames per mouse wheel movement and I'm getting two and a half frames per mouse wheel movement. I wonder if it is mouse sensitivity differences causing that? Once upon a time in Windows you could set the dpi of some mice but I no longer seem to be able to find such a setting in my copy of Win 10 so have no idea of the scanning sensitivity of the mouse. If it was possible to adjust that parameter would it be possible to change the amount of frames jumped per mouse wheel movement?

Also are you seeing the same behaviour when trying to use the scissor tool? IE, making the cut to the left in the timeline.

I hadn't got a silent video file to hand to test.

Hi,

Interesting. I never thought that the mouse could be anywhere but on a frame edge. Using the mouse wheel, I get several intervals between frames. Zoom way in on the object to see this. I noticed that, depending on how far along the frame the playback marker was place, the chapter marker would go to the next edge or the previous edge. If the playback marker is at about the middle of the frame (using 29.97 fps), then the chapter marker was placed at the end of the frame, but the trim point at the beginning of the frame. If the playback marker is before the midpoint, the chapter marker is at the beginning of the frame, as is the trim point.

If you zoom in to frame level and drag the playback marker with the mouse, it moves smoothly along the timeline within frames, but as soon as you let go, the playback marker goes to a frame edge. In VPX, the playback marker will stay at the point within a frame when the mouse is released. The jog wheel moves in small increments whereas the mouse doesn't, or at least it doesn't appear to.

Ray, the Shuttle Pro inner wheel moves one frame at a time and does not go within a frame like the jog wheel does.

Hi John EB,

I had completely forgotten about that other thread.

Hi John, Al.

This gets more curious.

In VPX the mouse wheel movement of one positional rotation gives me a two and a half frame jump but in MMS it is one and a half frames. I tried another experiment and adjusted audio frame buffers and samples with no additional effect so Al's observations are correct.

However, adjusting the audio buffer and sample numbers upward does make the audio more intelligible while scrolling. (at least to my ears) The downside of that of course is the delay between a play command and the program responding becomes slightly more laggy.

It is good to know nothing is effecting the shuttle pods.

Hi Ray

My mouse moves about 1 1/3 of a frame for each scroll 'click'.

Mice can have different 'resolutions' for the scroll wheel advancement, add in the scroll parameters in the driver, where they are available, and the Windows setting, Mouse, Scroll wheel settings the likelihood is this is always going to be different from system to system.

. . . . I'm wondering if the shuttles have similar behaviour. . . . .

The way I have my Shuttle set up:

• The inner dial moves 1 frame per 'click'
   
• The outer dial goes up in steps 1, 2, 4, 8 and 16x the project fps.
  
  At 16x the time taken to traverse a 10 min section of the timeline took 38 secs (project was set to 50fps).
   
• The 2 buttons for fwd /rev play behave the same as the J and L keys, ie repeated pressing of the J or L key goes up to 128x.

Hi John.

add in the scroll parameters in the driver, where they are available,

In my case that should be an 'if they are available'.

I used to have that available when I was using the Microsoft Inteli-mouse but my current generic optical mouse has no ability to change sensitivities of the mouse tracking ability or mouse wheel sensitivity. It works just fine for most things using the Windows settings that are available.

Unfortunately I have a long list of things that need seeing to that have priority over this as for me it is not a big deal. Not being able at present to download images from UDMA memory cards into Windows at the moment is more problematic for me. I haven't used such memory cards for a few years now but yesterday I used a few and they performed OK in camera but my card reader now seems incapable of reading them. This is not a request for help as it is not related to either this topic or video but show how things just keep creeping up in the world of computer compatibility.

You think you have it all sorted and then Bam! The game changes.

Ray.

I don't think it's got anything to do with Windows or the mice. It's a program issue. In VideoRedo, I can set the mouse wheel roll-click to 1 frame, and that's what it gives me, a one-frame advance with each wheel-click.

I would still like to have the option to speed up the scrubbing, similar to the CTRL+arrows. It's annoying and slows me down when I have to take my hand off the mouse to hold down the CTRL key.
