Why won't Resolve "resolve" the last minute of my footage?

So I've been trying to edit footage of this year's Perseid meteor shower, but have run into a problem. When I try to render all the edited footage together, for some reason the last minute or so is not included. It should be 8:26 long, but the most I've managed to render is 7:33.

I started out with the intention to render the footage in two formats, divided into two parts/halves (see the screenshot included - the first half is the large single section of footage), as well as a single (8:26) part, and I've managed to completely/successfully render both parts individually, but no matter what I try, I can't render it all in one go. I realize I could take both already rendered parts, and then join them together in Resolve, but that does not sound like an ideal solution, so I'll only use it as a last resort.

I'm still a novice when it comes to Resolve, and mostly self-taught, so I'm probably doing something wrong. The intention is to condense a night's worth of meteors into a few minutes, simply by editing out the (sometimes long) gaps in between meteors. Here's an example of what I'm trying to do from last year's Perseid meteor shower, if anyone is interested - it was my first attempt, so I have tried to learn lessons and improve this time around. I can't remember running into any rendering problems last year.

The process this time around was to cut out all the intervals from each individual clip (12x 29:50 clips that cover just under 6 hrs), and for the first half, I created a new compound clip for each set of meteors from a single 29:50 clip, and merged all of those, as I went, into the single large compound clip you can see in the screenshot below.

Then for the second half, I stopped making compound clips after the first 29:50 clip (the second largest section of footage you can see the the screenshot below), and left the rest as individual clips until I got to the end of the process of snipping out all the meteors.

So does anyone have any ideas what I could try, or if I'm doing something obviously wrong?

For some reason there is an exclamation mark on the "timeline 1", which I often get, and it does not seem to do any harm (at least when I work with single short clips, usually of meteors - something I do on a regular basis), but perhaps that is an issue that has contributed here?

I also had trouble early on in the editing process, the second time I started up Resolve to continue the saved project since all the raw clips are stored on an external hard drive which I access via a USB HDD caddy, and when I powered up the HDD caddy, Windows assigned a different drive letter to the previous time, meaning all the paths to the clips were off, and Resolve could not find the footage. I eventually resolved that problem by using a second caddy and juggling hard drives till Windows assigned the drive the correct letter. I doubt this is relevant, but just mentioning it for the sake of completeness!

Are you sure that you don't have In/Out points set on the Deliver page? It's easy to do this accidentally if you hit the "I" or "O" keys while on that page. If the page is set to render "In/Out Range" then it will only render the portion of the timeline that's within that range:

I think you're referring to the checkmark in the little red triangle in the upper right corner of the timeline's thumbnail in the Media Pool panel, right? That's just a flag that indicates which timeline is currently being displayed in the viewer, nothing to worry about.

Thanks Sean. I'll check the in/out points and post back here.

Yes, the checkmark is in the media pool. Good to hear that it's not an issue.

Can you post a screenshot of your export settings?

I've attached one below. The thing is, I loaded up the project in Resolve, made a new compound clip, and it rendered all the way through this time. I can't understand why, as I didn't change any settings. Seems like it was already set to render the entire timeline (rather than between in/out points).

I'm going to start editing the footage from a second camera, so if it happens again, I'll get some more screenshots (and hopefully document the cause this time)!
