When I run the script, I get nothing in the array for console.log(JSON.stringify(silencePoints));
I tried adjusting the DB, with no luck. What do you think I'm doing wrong?

@shervinshaikh well, notice that your shell says -af: No such file or directory -- makes me think your ffmpeg isn't parsing the options in the same way as mine. (It happens, ffmpeg is notorious for having incompatible versions.)

I'd try to cat silence.txt and make sure you even have any breakpoints in that file.

What are the options you have parsed? I have the same error.

I found the solution: replace the $1 in the command /usr/local/bin/ffmpeg -i $1 -af silencedetect=n=-50dB:d=1 -f s16le -y /dev/null 2>&1 | tee silence.txt to your file name you want to edit. Thanks for the script

Hi all, with Catalina 10.15.4, osascript is not allowed to send entries (1002)
execution error: Error: Error: osascript n’est pas autorisé à envoyer de saisies. (1002)

How you fix that ?

EDIT Solve : Add Terminal and apple script in security préférence / accessibility and input

If your video is in 30 fps you have to change this line in this script
let decipart = (60 * parseFloat("0." + deciseconds))
to
let decipart = (30 * parseFloat("0." + deciseconds))
and it work great
thanks jashmenn for you work.

It's not working for me :/

Here's what I am doing:

• I have imported my .mov video to FCPX at the beginning of my timeline;
• Then I ran the command to generate the silence.txt file passing my video as parameter (no errors are shown, but not much info as well). Please see my silence.txt below.
• Then I execute the command node final-cut-it-out.js silence.txt (is this the correct way to execute it?).

Bonjour à vous EnseignantLapro,
Je suis le rédacteur d'un ensemble de documents pour FCP X (martingosset.com) et écris quelques modestes application pour les monteurs FCP X (http://martingosset.com/boomerang-app/). Mais uniquement en Applescript.
J'aimerais vous contacter car je pense que ce petit script en intéresserait plus d'un. Mon idée serait de générer un XML grâce au fichier txt que semble gérer ce script; et plutôt que de faire faire le boulot de coupe et suppression par ce dernier. Je pense que je serais capable de le faire en Applescript que je connais et parce que j'ai bine l'habitude des FCPXML.
C'est sauf que j'ai peur de mal m'y prendre pour installer ce premier script ici présent.
Si vous aviez la gentillesse de m'épauler un peu pour cette partie, je vous offrirais avec grand plaisir mes documents ... en échange et pour ne pas que vous vous sentiez trop exploités ;)
En attendant de vous lire
Martin Gosset

I finlay choose another way to delimitate those silents parts : with keyword !!!... and wrote a small app in applescript that create an FCPXML... https://vimeo.com/415340397/f28424553d
Thank Jashmaenn

That looks amazing and is exactly what I need - something to just identify silence in Fcpx. Would you be willing to share your app?

Hello hamletcat... this app is now available on my website : (english : http://martingosset.com/boomerang_english/ and french with other app : http://martingosset.com/boomerang-app/)
Thank for your interest...

I have some insights as well as an issue.

I've gotten this script to work by running the ffmpeg command with an audio file exported from FCPX:
ffmpeg -i instructional.wav -af silencedetect=n=-30dB:d=0.2 -f s24le -ar 48000 -y /dev/null 2>&1 | tee silence.txt

Then running ./final-cut-it-out.js silence.txt works perfectly.

It works great for shorter clips, but when trying to do this with a 6+ minute clip, the cut points are skewed. I tried doing a test with a 30 second clip, a 6 minute gap, and the same 30 second clip. The tool works fine when dealing with the first 30 second clip, but the cut points are off by 0:12 frames for the second 30 second clip.

Any ideas on how to fix the code to account for this?

Fixed!

This article gave me some insight >> via Frame.io

I'm shooting in 23.98fps, and there's 3.6 seconds of drift between real time and timecode.

function moveToTimecode(timeInSeconds) {
    delay(0.1);

   	/*
    	https://blog.frame.io/2017/07/17/timecode-and-frame-rates/#:~:text=In%20order%20to%20properly%20fit,a%20standalone%20HD%20video%20format.
			Just to get an idea of the numbers, with a camera shooting in
			Free Run at 23.98fps, the drift will also be 3.6 seconds after 
			one hour of real time so the timecode count will be 01:00:03:14. 
			(0.6 seconds x 24 frames a second = 14.4 frames).

			3600 seconds in an hour >> timecode is 1:00:03:14
			3600 realtime >> 3603.6 timecode seconds
    */

    const driftRatio = 3603.6 / 3600

    let realTime = parseFloat(timeInSeconds)
    let timecodeSeconds = realTime / driftRatio


    // convert timeInSeconds in decimal to timecode values.
    let [seconds, deciseconds] = timecodeSeconds.toString().split(".");

    let d = new Date(null);
    d.setSeconds(parseInt(seconds));
    let hourmindays = d.toISOString().substr(11, 8);
    let decipart = (23.98 * parseFloat("0." + deciseconds))
      .toString()
      .split(".")[0]
      .substr(0, 2);

    if (decipart.length < 2) {
      decipart = "0" + decipart;
    }

    let timecodekeystroke = (hourmindays + decipart).replace(/:/g, "");
    console.log(
      "  timecodekeystroke ",
      timeInSeconds,
      hourmindays,
      decipart,
      timecodekeystroke
    );

    se.keystroke("p", { using: "control down" });
    se.keystroke(timecodekeystroke);
    se.keyCode(36); // Press Enter
  }

Hey! Can you guys create a video tutorial from zero teaching how to use this code?
I don't know nothing about programming and I have been looking for this feature for a long time ago.
Unfortunately I haven't been able to use this code.

This worked excellently - thanks a bunch!!! You saved me a ton of time!
