How can we improve Premiere Pro?

Nested Audio Waveforms Incorrect

In both Premiere 2019 and 2020 waveforms of rendered audio from a nested clip are offset incorrectly in the timeline.

Sometimes they will display correctly immediately after an audio render, but after the first edit (trim, ripple, etc) the waveform is completely wrong. It appears to generated correctly but be offset by a significant amount when displayed.

This makes it impossible to use waveforms on Multicam or Nested clips if I've applied effects/gain to the audio in the nest, therefore requiring rendering.

This was working at the beginning of 2019. I'm not sure when exactly it went wrong. Thanks for your help.

    Is this the same problem I'm having? It sure looks like it.

    I'm multicam editing a 90-minutes music performance. Towards the end of the process, video/audio becomes out of sync. Switch to the nested sequence to see what's going on, everything is in sync. Go back to my multicam sequence, all audio waves are in sync, all 4 cameras are in sync. I've done these multicam edits maybe around 50 times, I've never seen a bug like this.

    How is this acceptable? As a young professional, I'm at a loss as to how such a big error could be released by an $11B company.

    This is not a nice to have- editing hours of multicam sequences for an online course without seeing an accurate wave form is costing me hours of my life. Please fix these foundational problems Adobe.

    This is fixed, and is in the current Beta. It should be in the next release of Premiere.
    We JUST barely squeaked it in this decade.

    I too am having this issue, though not consistently. (Sometimes when I nest a sequence the audio waveforms appear, other times I have to render them. I don't notice this issue often, but when I do it makes doing things like subtitles or closed captioning a huge pain.)

    Hi all,
    I've been able to reproduce a bug when executing Render Audio command on a nested sequence. It is logged with the internal bug number DVAAU-4202616 for reference. Thank you for the bug report.

    This issue has persisted for the better part of 10 years. You nest a sequence, render the audio to see the waveforms, and all is well - until you trim, cut, or otherwise edit the nested sequence. Then the waveforms get completely screwed but yet Premiere believes they are rendered and correct and will not re-draw waveforms if you attempt to re-render the audio. The only way I can get around it is rendering a .wav file of the nested sequence and then replacing the audio in the main timeline/relinking to the nested sequence. Not ideal (esp. if changes are made inside the nested sequence - have to re-render the .wav and replace in main timeline). Time and energy suck for something that should be relatively simple.

    Exact same problem here. Right now Premiere is not really usable with nested sequences and waveforms. Very frustrating...
