Mini Gaps Between Events

johnmeyer wrote on 4/25/2002, 12:23 AM
I keep finding tiny gaps between events. These gaps are generally less than one frame in duration. I have all the default snapping options turned on (all four of them in the Options menu). It appears as though events are somehow getting trimmed by a fraction of a frame, and then the snapping won't work. Sometimes the render works fine, but sometimes I get a single frame of black.

Any clues of what I should do to avoid this problem?

What do you see at that transition when you zoom in far enough to see individual frames? Is there a gap on the screen at those points? One problem i've found often is that the audio part of a clip might be a fraction of a second longer than the video portion. When i snap the next clip to the end of the previous one, it snaps to the end of the audio instead of to the end of the video and leaves a short gap. If it looks like this might be happening, just move the next clip back another frame or two.

John,

I've noticed this problem too (see my post "Quantize to frames available in VF?")

I think this was a problem with Vegas 2. It's fixed in Vegas 3 with the "Quantize to frames" option. I believe that "Snap to frames" in VF should work the same, but it doesn't. The most obvious flaw is moving the cursor with the left/right arrow keys. It will move by one screen pixel at a time which may not land on a frame border. Splitting events at this point will create odd size events which cannot "snap" correctly at both ends. You will need to "trim" the right side of the event to snap it to a frame border.

To avoid this problem, just remember to use the ALT-arrow keys if you are going to make fine adjustments to ensure that your splits land on frame borders.

SF can you comment? Will this be fixed in a future update version?

jimcho,

I think you are correct. I use the cursor keys to navigate, almost exclusively. When I want to move one frame at a time, I of course use Alt-arrow, but often I just use the arrow key. It never occurred to me that the movement wouldn't be exactly along frame boundaries. I wonder why more users don't have this problem, and I suppose the answer may be that most people probably use the mouse exclusively.

I too would be interested in any comment SF might want to make on this, including any possible workaround. I've looked at the "secret" options menu, and it does have some settings related to this called "quickfade" that are mentioned in the Vegas forum. However, I don't really want to mess around with anything like that unless SF says it will help.

I just did a quick test. Sure enough, if you use just the right or left arrow to move through the clip, the cursor does not always snap to frame boundaries. By contrast, if you click with the cursor, the cursor ALWAYS lands on a frame boundary. The workaround is obviously to always remember to use ALT-right arrow or ALT-left arrow before pressing "S" to split the event. This is very awkward however.

Does anyone have a better way around this? Is this a bug?
