Crash because of multiple audio tracks?

[Earlybite]

Hi,

back again with a question!
(At the end of the post the protocol…)

Yesterday I recorded a flight with my favorite flight sim with OBS, I put that file into the time line and split video and audio and added then in an additional audio line a separate MP3 file…, and edited this…, and, hopefully, because I now have no variable framerate any longer, I started the export, but the export crashed after some percent.

Then, my idea was to try with only ingame sound…, worked. OK.
Then, I tried with only that separate MP-3 file…, worked. OK.

Then I had a look on the bitrate of ingame sound and that MP-3 file…, different.
So, I changed the setup in OBS to the same bitrate (48000) as that MP-3 file has.
And I made a small record from a flight, put it into Shotcut, split video and audio and added again that separate MP-3 file, and export was fine!

Hurray, I thought, now I fiddled it all out!

I flew a mission and recorded it, put that file into Shotcut, split video and audio, and added again that separate MP-3 file, edited it, brought it to ca. 5 min to test it…, export…, crash (after 8, 9 percent).

What is the reason that the export crashed, that I can fix it?

Best regards
Earlybite

Developers need a way to reproduce it to fix it. Is the problem with a certain mp3 in a certain track configuration. Tell me less about your story and more about the facts needed to reproduce the crash including possibly sample files (.mlt and .mp3). In the meantime, you can try to convert the MP3 to WAV and see if the problem goes away (knowing a workaround is useful information as well).

I’ve already tried with a convert MP-3 file, but into MP-4, with no success.

Currently I’ve find a way, so it seems currently, two times, two times success with export.

I’ve uploaded two pics…

This is from the unsuccessful export.
First four parts are PNG pics, then the raw file from OBS with the split video (video / audio) and the separate MP-3 file.

Again four PNG pics, but in an own track!
Then raw video split into video and audio, then that separate MP-3 file.
And here already with an additional MP-3 file added in the same track with transition to the other MP-3 file.

With this configuration the exports works!

But to be honest I changed also the bitrate in the export settings from 384 to 128…, maybe?!

Currently I want to finish that video. Howsoever!
If that is done, I will try other ways to create a video with PNG pics, split raw file and additional MP-3 files, also in “only” two tracks, but with a bitrate of 128…
But currently I will be happy when I’ve finished that video.

And, BTW, I didn’t wanted to tell “my story”, I do not know, what is important for a dev here, so I took my thoughts and words that should explain what has happen…

Thanks for your answer and
with best regards

----------------------EDIT---------------------

I’ve got it! Completely! 28 min., 3,5 GB, 2,5 h…

Now, let’s see what can be done, one way is found.
