tiny gaps between clips

When I place avi files on my time-line they will not merge exactly. There is always a tiny gap. I can't drag them together until I cut the last video frame from the clip to the left of the gap. (cutting the first frame from the second clip doesn't help. There must be something wrong with how the avi files are terminated. Here is a screen shot showing what it looks like zoomed into the gap.

any ideas what causes this?
The avi files are created by a time-lapse program that grabs frames from an IP network camera

Looks like the clip on the left is extending just past the frame boundry so it needs to be shortened to END at the frame boundry. You should be able to move the clip on the right left one frame anyway. It would just create a sub-frame crossfade.

To start, make sure you match media 'properties' under 'file<properties' with the yellow icon.

Note that your source video is 30fps, but your project is set to 29.97002997fps. This means that the frames of the video will only line up with the frames of the project about once every 3000 frames. Except for these rare cases you're always going to have the gap that you see. Ed's solution is quite workable ... simply drag the next event to the left to overlap.

Unless you really need to make a 29.97 project, you might want to consider setting the project properties to 30 to match the source material.

If you do want to make a 29.97 project then you should probably right-mouse-click on all the source events, go into properties, and set them to disable resample. You'll end up dropping one frame every 3000 or so, but you won't have any blending going on. Personally i'd rather lose one frame every few minutes than blend when the frames don't line up.

Thank you Chien et al
I can't drag the right clip to the left. It stops at the gap as if that was the end of the clip. Also note that the last frame in the left clip is smaller than all the other frames. If I cut the last frame on the left clip the two clips snap together . I will try fiddling with the frame rates.
