"Remaining Time" doesn't decrease when exporting large files

I’ll say off the bat that this isn’t a usability issue - it’s purely cosmetic, although it would be useful to have an ETA on rendering. I’m just reporting this because it seems to be a bug. I work with radio shows to convert recordings of their shows to streaming audio formats for podcasts. These are usually about two hours long each. I’ve noticed since updating to either 2.1.0 or 2.1.1 (I can’t remember which, sadly) that, when exporting a file this long, the progress bar on the export dialogue doesn’t move at all and the “Remaining Time” just increases steadily by about four minutes every second until the export finishes. This still happens after updating to 2.1.2, and it happens no matter what format I export it to (I use both Ogg and MP3). The good thing is that the file does still finish exporting anyway, so it’s just a cosmetic problem, but, at least for me, by the time that it’s finished exporting, the supposed remaining time has reached 40+ hours.

If this is just on my end, I honestly have no idea what’s causing it, but I’m hoping that bringing it up might at least help in some way.

I’ve tested this with Windows 10 on 2.1.2 and the latest 2.1.3 alpha nightly with a 2-hour show exporting to MP3.

The green progrees bar moves correctly - and the Elapsed Time and Remaining Time are updated every second or two.

So I’m puzzled at your report :confused:

Like you I record three shows each week of one 2 hours and the other two one hour shows - and then export those to MP3 for use on the Internet. I’ve never noticed any problems with the Export Progress dialogue.


Hmm, that’s really strange, then. I’ll try a clean install of it - maybe I managed to break something ages ago, but I have no idea. I’ll let you know if it works, either way. Thank you for your reply.

Thanks for the report. It’s nothing to do with different operating systems. The bug occurs if one track is much shorter than the others, which is the case in your screenshot. The bug is in 2.1.2 release too, as described in the 2.1.2 Release Notes.

The bug has now been fixed in our source code so will be fixed in the next 2.1.3 release.
