Have you tried to import the trouble file directly (not opening the project?) Still error ?
Also delete/clean your media cache and database, open the project again and wait for conforming/indexing to finished. This usually fixed the problem in weird offline file issue.

Since Premiere CC 2014.2, the best way to do it is to use dynamic link between Premiere and AE.
Before this version, a very heavily animated composition in AE simply wouldn’t playback in realtime in Premiere dynamic link in many machine.
But right know, you can do a render to that AE comp in premiere with your codec preference (Cineform or DNxHD), thus allowing you to preview/playback in realtime. And you can revert back to original comp with ease (wasn’t possible directly in past Premiere version)

Also, in the Premiere recent version, there’s a feature to allow you edit the text from AE Comp directly in Premiere, very handy to use if you make lower 3rd. Personally i haven’t try that out though, maybe you should check that feature.

If possible, care to share the project files and the sample media ?
Preferably from the same video you posted.
You can post your email then i can email you to exchange files if you don’t want the footage in public forum (because i wasn’t sure how Personal Mesasge in this forum works, i didn’t see a PM button !)

Hmm,..probably different error from what i’m experiencing in the past (different container, from different camera manufacturer, forgot about the types though, happen 1+ year ago.)

Other than your Radeon; spec wise, actually you shouldn’t have a problem exporting your project at all.
CMIIW, but radeon isn’t natively supported in Adobe.
I really didn;t have a clue with Radeon, i never use it.
So, have you tried to render with “Mercury Playback Engine Software Only” ?

Did you use the most recent version of AME and PPro CC ?
I remember reading a update release notes regarding AME (?) throwing an unknown error (?)
But darn it, i can’t find the link (but probably some old release notes / CS 6 etc).
Many things can cause the export to crash in CC 2014 prior recent updates.
Make sure you do that first,and restart.
When it crash, did you notice a pattern ? Did the failed exported video is always failed in certain time mark ? A corrupted source video might be the culprit if this was the case.

If you want to convert your clip, just batch encode them in AME with the same setting for all camera with the same filename.
Batch rename the current video with suffix “Old” (or anything you prefer).
EG: MVI_001_old.mov
This way, when you open your project, premiere will “missing” that old file. All you have to do is re-link the new encoded video. This is why it’s important the new encoded video has the same name like in the original file.
And make absolutely sure you have a exact setting (frame rate, size, etc) in your newly transcoded file like the original.

But make that workflow as your last option. Since it could be the error is nothing to do with your source video.

As a test, did you use any 3rd party plugin ?
Test a barebone render (no fx,grading, titling whatsoever, either in video or audio), no transition other than built in Premiere.
You can remove all fx easily by blocking all the clip and select “remove effect” (Clip|Remove Effects)
See if you can success rendering your project out.

I’m sure you already know this, but i’m saying this for the sake of clarity since you say you fairly new to Premiere: Do that with duplicate project, there’s no need to breaking down your original project file.

Regarding your question about the render setting (your workaround, rendering with splitted project, joined them afterwards).
I don’t think rendering to ProRes LT is a good path, the quality will suffer IMO, especially you want to do multipass.
At the very least, you want to export as ProRes HQ, or even better to a lossless codec.
With lossless codec, you will not lose quality whatsoever, as if you were rendering directly without splitting.
Bear in mind lossless will produce a bigger file than the compressed ProRes.
There’s no need to export to uncompressed if a lossless codec is available.
(much smaller size compare to uncompressed).

TLDR:
1. Clean your media database/cache in the preferences.
2. Try rendering in “Mercury Playback Engine Software Only”
3. Do a barebone render test, see if some third party plugin causing it. Or in some case, even built in Premiere fx can be the culprit (prior to updates). You might discovered a new bug.
4. If all fails, split the project, because you said it works , but render as lossless instead.
5. Convert all source video into single setting, bear in mind, you actually lowering your source video quality, unless you re-encoded them with either lossless or uncompressed.

Notes: Option 4 is much better than option 5.
Option 5 is last option if all fails, and in all my work i actually only do that one single time due rare crash with weird mix container from different types camera.

Edit:
TLDR Typo

Sorry for replying a very old thread. But i’m curious and need the same workflow as yours.

So, what’s the verdict ? Does it work on CC ?
Btw, i’m using CC 2014.2

Sorry if i misinterpret your post (since i don’t do Closed Caption).
But i just test it, and you can group the CC track with video as usual and it’s movable in the timeline.

Your frame rate is 0,00

Have you tried to convert with another third party tools? Try with FFMPEG. If the problem persist, then the video you trying to import is corrupted.

In all cases, did you happen to mix format in the timeline?
In one of my project, i encounter this problem, fixed it by converting all footage into the same format (the footage came from different camera)

If only happen in single file, then it’s corrupted file. Try to re-convert to something else, see if the problem gone.
