Automatic Trimming (Ripple Delete) of Silent Audio
When producing and editing a recorded session, there are a lot of "gaps" in the recordings where I have no audio being spoken. In order to produce this screencast, I must go through and ripple delete all of these "gaps".
As a user, I would like to be able to have a selected clip and trigger the gaps to be ripple deleted automatically. It would be helpful if there were configuration options of
- maximum dB threshold to be an identifying factor for detecting silence
- configurable padding (leave 1/4s, 1/2s, 1s) of silent audio before and after cut
- option to retain silent audio but just a slice is made instead
In the example image attached, the blue highlighted area is what I need to Ripple Delete, but there could be 50 of these on this particular video clip. The end result is what you see to the left of the blue highlighted area.
This would greatly reduce the amount of work I have to do on ever video and would save me 10+ hours each week. This would be a HUGE feature for me.

Also, fill out the Feature Request Form so we can give you a case number for direct communication if needed.

CraigS I did fill out the form, but when I submitted it, the web page went blank. I'm unsure if it submitted or not.
-
Dave Kimura I confirmed we got the submission.
Case #00729831 -
CraigS Thanks. I did end up submitting it again and it looks like it did go through that time. I sincerely hope that this makes the roadmap. :) Thanks!
-
Dave Kimura You're welcome of course.
-
This would be the most time-saving feature for me. A huge portion of my video creation is spent with finding and deleting silent parts!
-
Also a huge thumbs up from me. I'm a recent convert using ScreenFlow to make online physics lectures. I like to edit out the long pauses where I'm writing uninteresting but necessary details on my tablet for an example. If I could press a button that shortens all silences to ~1 second via ripple deletes and then does a cross dissolve over the remaining time, my editing time would go to almost zero.

100% - this would be a game changer
-
An example app that does this: Vlogeasy - but would be much better to have this integrated as a feature in screenflow. Loads of guys on github have made their own pythonscripts to do this, it doesn't seem technically too difficult and would save HOURS of editing time
-
Propane You have to vote for it though, not just comment.
-
Great idea!!!
-
Igor VOTED!

Internal reference for our feature investigation FLOW-10361

Really useful option!
Also ability to set the default gap at the end & beginning.
-
I would also love to see this. 90% of my time (or my editor’s time) is spent just cutting out these gaps. 👍

Danny Connell me too my friend ))

I recently got a stream deck from elgato which has helped me cut down on the amount of time required to do my edits, but this feature would still be awesome to have. I'd love to get to a point where my edits took less time than to record. This feature would definitely accomplish that.

Hi
-
Please make this work for webcam recordings that include video along with audio.
-
Patrick McDonald That's how I'd think that it would work. It would basically do an automatic ripple delete of the silent audio. So any detached video above or below the selected audio on that timeline would also be trimmed.
-
Oh yes, please. That would be one of the most innovative and useful features ever.
-
Yes please. Need this desperately :) would save so much time!
-
James Miller You must add to the vote total. Developers look at the votes.

In the meantime, as a workaround, I use ffmpeg to trim all the silence out of my audio:
1. Record the audio in screenflow, remove background noise and export in .aiff format
2. Run the ffmpeg in the command line to trim the silence:
./ffmpeg -i input.aiff -af silenceremove=start_periods=1:start_duration=0:start_threshold=0:stop_periods=-10:start_threshold=-50dB output.aiff
3. Import output.aiff back to screenflow

Irek Mirgaleev I think that this would work if you didn't have to worry about the synchronization between the audio and video.
-
Dave Kimura Correct! I tried to edit my post to make it clear but looks like editing gets disabled after some time.

I would greatly appreciate automatic ripple delete of silent audio and have up voted this.
However, I noticed this request is a year old. If this feature is too challenging or too much work for the devs (or just not enough of a priority), perhaps a halfway solution would be to automatically ripple delete all "tagged" or labeled clips. I go through my clips and label all the ones I want to delete in ORANGE color (for example). Then I go back and manually ripple delete each grouping of orange colored clips. It would be amazing if I could just tell Screenflow to automatically ripple delete all clips that are colored orange instead!
Would an automation feature like this be simple enough to add in?
-
Ben Thanks for those suggestions. The developers and product manager are certainly aware of the interest but must consider the best approach for a long term solution.

-
Please. This feature is SUPER important. Particularly with the rise of YouTube and webcam recording.
We really need this :)

I've found the tool https://getrecut.com/ that can trim silence from the video and can export right to ScreenFlow. However it can't import the ScreenFlow files, only .mov or .mp4 that can take the quality lacks because of double export.
For ScreenFlow developers. I will not upgrade to SF10 while you don't implement the really needed features that will speed up editing like trim silence or whole timeline speed. Start to give what the community wants and take my money!
