![]() ![]() Notice the segment of silent audio in the middle (see "Fancy waveform" below if you want to see how to add a line).ĭefault colors are red (left channel) and green (right channel) for a stereo input. Thank you for all of your help.Ffmpeg -i input.wav -filter_complex showwavespic -frames:v 1 output.png However, at least this gives me a point to start troubleshooting from. There haven't been any other system/software changes to the machine that I'm aware of. I find this odd because, as I mentioned before, this only started happening after upgrading to resolve 18. When I just play these clips back with VLC Player I believe I can hear that small gap in those two files so that may just be the way they were recorded or some small nuance with the cameras they came from.Īll of this would seemingly point to an issue on my production machine. Only the Panasonic and GoPro footage have a much smaller gap at the front end. When I opened the project on the new machine I got the same results as Charles did. So, after reading some of your replies, I decided to install resolve on another windows machine to test. I do have many clips of people talking that exhibit these issues but the audio is synced properly in them so I don't believe it is a sync issue. That helped me a bunch.Ĭharles Bennett wrote:Could this be a sync issue? Do you have a GoPro or Panasonic clip that has a distinct visual sync point in it, and are the pic and audio aligned? I'm curious if you deleted you waveform cache like a I mentioned further up. I think this is just an artifact of these clips. ![]() But this is not the missing-big-chunk-of-waveform issue that the original post (and my earlier post) was about. This happens to me with Filmic Pro clips consistently, but the same issue appears in Final Cut Pro, so I'm thinking it's just how some apps encode things. You can see this is some of my screenshots. On both OSX and Windows, some of the clips have no waveform for the first few frames. The EDIT page looks good unlike your screenshot. But the actual clips look ok on the CUT page. On windows, the timeline and timeline thumbnail is missing a waveform on the CUT page. NOTE: On windows there is no video for the mp4 file, I guess I'm missing some codec, maybe HEVC. Waveforms show up for me on both systems. If someone on windows 11 could test it to confirm whether it is fixed or not for them, it would help to isolate the issue I gave this a shot on OSX and Windows 11. I wonder if it's a bug only in the windows version then. Steve Alexander wrote:I downloaded this media and project and the waveforms appear just fine on my MacBook Pro (see signature) running Monterey 12.4. If I cut the section of audio with the missing waveform out then playback is normal. It only seems to have the silence when the playhead moves on to a new clip with the missing waveform. However, if I stop playback and place the playhead anywhere in the section of audio with the missing waveform and play the audio will playback fine. ![]() When playing back audio in a project, when the playhead moves to a new clip and that clip has the missing segment of waveform there will be silence in the audio most of the time. It is possibly unrelated to the OPs waveform issue.ĮDIT: To expand on how the audio plays: After testing this further, I have noticed that when playing back audio that has the messed up waveform, there are some issues. I tested this on my end and didn't have the issue you are describing. Can you test on the Fairlight page if when you middle-mouse click and mouve the timeline the waveform appears and disappears (while you're zoomed in on the first 20 secs portion) ![]()
