I set a loop region on by double clicking the still. At the lower right corner you then have an "in time" an "out time" and a "delta time". Stretch the region by dragging the "out time" until you reach the needed "delta time", then place the cursor and stretch.
With some experience, it's a fast way to accomplish.

You may also find that if you stretch the time line with the up arrow key that you can get the presicion that you want.

Here is what I do, First of all make sure that you are set up as follows:

Go to the Options pull down menu. At Ruler Format select the proper time code time for your footage. In my case that is SMPTE non-drop 29.97.

Go back to the Options pull down and select Quantize to Frames.

These are the options that I use throughout the project for many reasons. I like my cut and edit points to land on frame boundries.

I hit the up arrow key until the time line clearly shows me frames. This is when the numbers are every 5 frames or so. I only do this when I need to move an edit or stretch a till to an exact length. You will now see that the cursor line will only land on frame lines. You can push and pull the stills length to exactly the number of frames that you want.

SoFO if you are watching, it would sure be great to have a right click pop-up or some other way to enter the exact length of a transition. It is a pain to stretch the time lime and drag the transisition (dissolve) to 15 or 10 frames. Since each dissolve has a feel based on the speed of the material before it using a default setting (which is frame accurate) does not work well for me.

Keith,

The scroll wheel also works well to zoom the timeline and is usually more "at hand".

I'm also in favor of making frame accurate transitions easier, but since an event group can be much more than just a video and audio event and can lie on multiple tracks, it could get complicated to implement.

But here's how SF could do it very easily. Just have assignable hot keys (perhaps the number keys?) that would simply slide the currently selected event group to the left by a predetermined number of frames. That way you could just butt your events together, hit your hot key, and have an instant frame accurate transition without messing up the rest of your timeline.

In the meantime, I use the "snap-to" handle at the lower-right of the event which you can easily slide to the right to get a frame accurate count. Then the event will snap easily into place right where you want it.

to address the questions about transitions:

Options | Preferences | Editing | Cut to Overlap Conversion...

will let you set a number of seconds. then when you overlap two events, they will snap to overlap for that number of seconds. essentially that lets you snap to a preset transition time.

the scroll wheel makes it easy to zoom right up and tweak if necessary. or use the shortcut keys to nudge the event one frame at a time (ALT+NUMPAD-LEFT/ALT+NUMPAD-RIGHT)

there are lots of shortcut keys that are geared for frame accurate adjustments.

I would suggest the ability to do caluclative additions/subtractions on the "cursor position", "start selection", "end selection" and "selection length" fields. Adobe products have this feature.
For example, say you want to point to a location 1 sec from your cursor position. Double click the "cursor position field" and enter "+1:00"
