I've encountered a strange bug. I have captions and an After Effects lower third on two different tracks on a timeline. Using Mac OSX 10.13.4, AME 12.1, Premiere 12.1.

If I render out of Premiere, no problems.

If I send to AME and try to render, the caption track renders as "Media Offline".

If I delete all content such that only the caption and the AE clips exist, the caption track renders as "Media Offline".

However, if I delete the AE content (turning off visibility doesn't do it) then the captions will render normally in AME.

It doesn't matter where on the timeline the two are; if both the captions and the AE clip exist together in the sequence, the captions will render as "Media Offline" in AME. Very weird.

Manual fixes are difficult because I have 50 or so timelines to render.

Adobe Media Encoder bug - Media Offline for captions w/ After Effects
I've encountered a strange bug. I have captions and an After Effects lower third on two different tracks on a timeline. Using Mac OSX 10.13.4, AME 12.1, Premiere 12.1.

It's Open caption. It's an SRT file that was imported; captions created inside Premiere work.

You should be able to replicate by doing this (this creates the error for me)

Premiere > New timeline (any kind)

Premiere > new color matte

Drag color matte into timeline

Create a new .SRT file and save it

Premiere > Import (select newly saved SRT file)

Drag Subtitles into timeline over color matte

EXPORT > QUEUE (loads media encoder, works fine)

Now, back in Premiere:

Premiere > Right-click color matte, "Convert to After Effects composition"

AE Loads, Save new project

Back in premiere:

EXPORT > QUEUE (loads media encoder, now notice the error)

I demonstrate here:

Export settings also don't matter. From within Media Encoder no matter what output settings you choose it appears as media offline. I've offset the captions vertically here so you can see the video behind; here are h264 and a quicktime DV output:

Files used in project don't matter. As seen in the demo, you don't need any video files.

Captions overall are pretty buggy. I find the interface to style captions very difficult to use; for example, why is there no easy way to format all the captions simultaneously (aside from manually selecting them, which is cumbersome)? It seems rare that users would ever want to style captions individually. Global styles for captions (in the entire project, and applied to new imports) would be very helpful. For example, if I have 16 timelines and have to import 16 SRT files, I have to manually apply styles to each individually. Time consuming and unnecessary. Also in a number of circumstances, captions do not update on screen after you update them in the interface; that is, I can change the text but what appears in the video (while editing) is the old version (however when attempting to export the correct updated text is used).

Also, if you add a stroke to the text of the captions, any characters with pointy corners (say, "M") will get this:

That makes the stroke unusable in professional contexts, it would be great to have that fixed.

Thanks!

When we export our premiere project via Media Encoder, 1 audio channel is NOT included. If we export the same project directly via Premiere, the relevant audio channel is included.

The corresponding audio channel that is not exported via Media Encoder has the following effects:
convolution reverb
multiband compressor.

When we switch off the effects, the corresponding audio channel is included with the Media Encoder.

We have tried different export settings. (H.264 and match sequence settings).
We have reset Media Encoder (hold shift while starting)
We have tried to render through Open GL and through Metal.
We tried to tick and uncheck "Import sequences natively".
None of that works.

everything works just fine.
