Ok, first allow me to say that I searched for an answer in the forum and already checked out these posts:
www.lwks.com/index.php?option=com_kunena&func=advsearch&q=insufficient+overlapping+media+dissolve&exactname=1&searchdate=all&childforums=1&limit=20&Itemid=81

www.lwks.com/index.php?option=com_kunena&func=view&catid=7&id=143120&Itemid=81

I do not understand what the problem is. I know I have way more media on both sides of the cut than what the dissolve will need. As a matter of fact, I have been using 10 frames for the dissolve (5 frames before and after the cut point) throughout my video and they have worked on clips with less room than what I have here in this instance.

I even zoomed in on the cut point to make sure that there wasn't a small amount of blank space and there was nothing....the two clips were right up against each other.

Maybe I am missing something obvious to everyone else, but I am completely lost.

If it helps, I am running Lightworks 14.0.0.0 (93145) - April 3 2017

You use an effect with 2 inputs as a transition effect on a cut:
Transition effect are mix effects.
Mix effects mix two videos (or pictures, etc.).
This also applies if the effect is operated as a transition, with the particularity that in this case a single video track is sufficient.
But how does it work if there is only one video in the timeline at the respective position? ....

Hidden from the eyes of the users, Lightworks splits the timeline within the gray transition into two separate timelines. So that both videos overlap in the hidden timelins, Lightworks has to extend the end, and the beginning of both videos. For this Ligtworks takes additional material from the clips, subclips, etc.

But if I put all the video into the timeline before, there's no extra material Lightworks could use to create a hidden overlap. In these cases, Lightworks will issue an error message.

Ok, I'm sorry, but that means absolutely nothing to me and it doesn't explain how I can go about fixing this issue.

Have a look through this sticky, which covers the causes and offers solutions, so may assist you:

Yes, I already looked through that post but it didn't help me.

Have you deleted the 5 frames in both clips? Doing so should create enough excess media required to allow the ends to overlap each other sufficiently to allow the transition.

As it writes @briandry.

And still avoid gaps.

A basic misunderstanding is probably:
It may surprise you, but the problem is not that you put too little Matierial into the timeline, but too much. The extra material for the transition does not get Lightworks from the material visible in the timeline, but always needs a little more material than is visible, no matter how much you insert. Lightworks need "unused" material to create a transition.

One of my favorite movies with Bill Murray is Groundhog Day.

Think in film, in order to be able to see two pictures the same time - that's what a transition does, film must overlap, so does video.

This video is from briandry's sticky, in case you've missed it:

briandrys, deleting five frames on both sides removes video and audio I want in that spot. So, I should actually delete both clips and then put them back in the same spots but with extra space where the dissolve will be? That seems very strange, especially when I haven't had problems like that in other areas. This just seems like a lot of extra work to get the result I want.

Hugly, I understand that concept of overlapping film sections in relation to this, but I did this dissolve exactly the way I did about 30 - 35 dissolves in this project I'm working on and didn't have this problem before.

Ok, I understand. Unfortunately the message doesn't give any information about the missing frames.

Please try: Press P-key to delete exising marks, Jump to the cut using A and S keys, use <cursor-left> to move 5 frames to the left, press I-key to mark-in, use <cursor-right> to move 10 frames to the right left, press X-key to delete the marked section, press F8 to open transition panel, select dissolve, centered here, duration 10 frames.

What happens?

Hugly, I have done exactly what you mention here and I get the warning message. This is the way I have done every dissolve previous to this one.

I see, let's assume this is a bug.

I'd suggest installing most recent V14 beta, downloadable from Downloads on top of this page. If the problem persists, create a new thread in recent beta forums and attach an exported archive of the sequence which shows the issue without media (de-select all includes).

If it's a bug there might be a slight chance to get it fixed prior to V14.1 release.

Humour me on this: to test what is going on here, try the deletion process (yes, I know that we will initially be deleting footage that you want to keep - trust me*). For the purposes of the test just do that and apply the dissolve, then without doing anything else come back here and tell us what happened.

*And trust me: we will restore your media once we know what's going on.

AND ABOVE ALL ELSE!!! Please DON'T install the 14.1 beta, and DON'T assume that it's a bug. Work with what you've got and we will find out what's happening.

Okay, so out of curiosity, instead of clicking on the Effects button at the bottom of the timeline and then going to Dissolve, I just pressed F8 and selected Dissolve from there and I did get the same "insufficient overlapping media" error but there was new text saying it tried to correct the issue and it applied the Dissolve. Unfortunately, now I have an "echo" about one second after my voice ended in the video. Maybe the easiest thing for me to do is just delete both sections completely and then put the same segments back into the timeline.
