How do you restore the Audio Wafeform?
Rebuild does nothing.
You are probably just getting the same result so it appears to not be doing anything.
This happens to me sometimes when I add mpeg files. I get sound but no waveform. And, the rendered output will have no sound. What I do is re-capture the video from the source. If you no longer have the source then SOL.
- I have a muted video track.
- add an audio track
- drag a .wav file into the new audiotrack
- select the audio track and cut at cursor position
Result: the audio itself is cut correctly, but the waveform display is not.
It is just copied, from its start, to the new, right-hand side clip, and does not match that clip’s actual audio.
Which makes the whole right-hand side useless for further editing.
- “Rebuild Audio Waveform” does nothing.
Only closing ShotCut, and re-Opening the project will rebuild the waveform correctly, but that is just not viable
Incidentally, the thumbnails at the start and end of each clip appear to have a similar problem, in that after a cut the right-hand side clip just receives the same start thumbnail as the start thumbnail of the left-hand side clip.
Edit: Shotcut 18.06.02, Windows 10
Edit #3: the left-hand side waveform is updated correctly, so you can somewhat work around the issue by putting another cut on the right-hand side, e.g. at the very end of the project.
Edit #4: … but then I tried to be really smart and re-join the clips from the “workaround”-cut, which caused the right hand side sound clip to disappear
Select the clip & refresh via F5
Yes, that’s what I wrote: the audio is fine, but the waveform is not. I do need the waveform for editing audio though; don’t you? It can not be refreshed, either, neither via F5 nor via context menu. I clearly wrote that, too.
From the advice that @Steve_Ledger has gave in other posts, you might wish to try Version 18.03.06.
You can download it here:
Or if you prefer an different version:
Splitting from version 18.03.06 works like it should for waveforms.
I second the above. I need the latest versions of SC because I use key-frames so much but I installed a copy of 18.03.06 to do some audio editing/syncing prior to adding key-frames on a couple of projects as a stopgap and it saved me significant time. Looking forward to 18.07
I’m running the latest 20.04.12 on Ubuntu 16.06 LTS (AppImage as always) and Waveforms still seem not to appear at random, or better said, I have not found the pattern that triggers some waveforms not showing. It happens either in projects with just one video track of a single clip, projects with 1 video (silenced) + 1 audio tracks of a single clip, complex projects with several tracks and clips. The duration of the clip seems not to matter. I have unsuccessfully tried F5 and rebuilding.
The way I get waveforms back is saving the project, closing shotcut and reloading the project in a new session. The main drawback for me is that I lose all the command history.
I am also not seeing the audio waveforms.
It started today, but I don’t know what triggered it.
It is making editing to speech quite laborious.
Rebuilding Audio Waveform doesn’t seem to help.
I have Show Audio Waveforms selected and toggling it doesn’t do the trick.
Unlike Alberto, closing and re-opening Shotcut doesn’t bring it back to life.
I am also running 20.04.12, but on Windows 10.
Are you running more than one instance of Shotcut (also check for hidden, hung/zombie processes)?
I fixed the problem by looking through the running programs in task manager after closing Shotcut.
It turned out there was a Shotcut process still running using only a couple MB.
I ended that task, re-opened Shotcut and the problem has not recurred.
