Problem setting up Lossless Cut CUSTOM keyboard shortcuts to work on the Logi MX Creative Console keypad

[SunGod]

Hey all,

Big fan of Lossless Cut, use it a lot for quick and dirty edits. I just got a Logi MX Creative Console, and am trying to setup custom buttons on its keypad to use with LLC, but am hitting a roadblock when it comes to having it trigger any custom keyboard shortcuts that I set up within Lossless Cut.

What I CAN do fine: I can successfully setup a MXCC button for play/pause in LLC. Works like a charm, all I have to do is set up that MXCC button as a Options+ keyboard shortcut for SPACE. Seems like the default LLC keyboard shortcuts can be triggered just fine from MXCC.

What I CAN'T do: I want to have a MXCC button for LLC's Tools > Detect Silent Scenes function. I use this to quickly find sections in my gameplay recordings where I hit pause so I can isolate them and delete them. I CAN create a custom keyboard shortcut within LLC and use it just fine within LLC - for example, I set "Detect Silent Scenes" to use "CTRL+S" and it works perfectly fine within LLC itself. HOWEVER, where things hit a wall is that when I configure a button in Options+ for MXCC, even when I use "Keyboard Shortcut" and define it to trigger "CTRL+S", it simply doesn't work at all.

I'm stumped. Since I can trigger the default LLC keyboard shortcuts fine using MXCC (play/pause), but NOT the custom LLC keyboard shortcuts (detect silent scenes), it doesn't seem to have anything to do with my MacOS privacy settings. I'm wondering if perhaps there's something about how LLC is architected that is preventing the MXCC from triggering custom LLC keyboard shortcuts?

Any help would be awesome. Thanks.

Following up here for anybody that encounters this. Skip to the bottom for a kludgy workaround that I discovered. I ran this by ChatGPT and it came up with the following explanation as to WHY it's not working (maybe this is helpful to the Lossless Cut developer?)

_

LosslessCut is an Electron app. Its built-in shortcuts (space to play/pause, J/K/L, etc.) are registered with Electron’s accelerator API—those are caught at the macOS layer, so any synthetic keystroke Logi Options+ sends is accepted.

When you create a user-defined shortcut inside LosslessCut the app instead listens for a DOM key-down event in its web view.
Electron passes such events only when event.isTrusted === true (to stop malware from faking editor keystrokes). Unfortunately Logitech’s “Keyboard Shortcut” output flag is isTrusted = false, so LosslessCut silently ignores it.

_

And here in my WORKAROUND to solve the problem. It IS kludgy, but it DOES make Lossless Cut custom keyboard shortcuts work using MX Creative Console.

1. Open up Logi Options+
2. In the top-right corner, click the "Smart Actions" icon (it looks like a circular arrow with a checkmark inside it)
3. Click the "Create" button (top right corner). A dialog will appear that allows creating the new Smart Action.
4. In the "If..." section of the new Smart Action, click the "Add trigger" field. (see attached image), click it and select "Shortcut" from the dropdown.
5. In the shortcut popup, where it asks you to press a key combination, on your keyboard press CTRL+S (press and hold CTRL then press S). The field should now show "^Ctrl + S". Click CONFIRM.
6. In the "Then..." section, click the "Add action" field. (see attached image), click it and select "Keystroke" from the dropdown.
7. In the keystroke popup, click the "START RECORDING" button. On your keyboard press CTRL+S (press and hold CTRL then press S). The field should now show "^Ctrl + S". Keep "Record with fixed delay" checked. Click CONFIRM.
8. You should now see both the "If..." and "Then..." fields populated, and both will show that you chose "^Ctrl, S". This is good.
9. Click SAVE
10. Next, go back to the Options+ main screen, and click on the image of the MX Creative Console keypad. You ALSO MUST configure a button on the keypad to make this all work properly. After you click on it, click on "CUSTOMIZE KEYS".
11. Your keypad will appear. If you haven't already created a profile for "Lossless Cut", do so now using the "+" icon above the image of your keypad. (See Logi's help for how to create a profile, there's no secret sauce to this particular step.)
12. In the System Actions list on the right, scroll down to find "KEYBOARD" and expand it to reveal more options. You will see a "Keyboard Shortcut" option. Left-click that and drag it to the button on your keypad that you want to configure.
13. When the "Keyboard Shortcut" popup appears, click on the "Key" field. Now press and hold "CTRL" and then press "S". The Key field will now show "Ctrl + S". This is good. Name your new shortcut and change the icon to whatever you want. (I named mine "Detect Silent Scenes".)
14. Click SAVE.
15. Next setup your custom keyboard shortcut within Lossless Cut. Go to "Help" menu (at top) and select Keyboard and mouse shortcuts. When the shortcut popup appears, find the shortcut you want to customize. (In my case, I customized "Detect Silent Scenes".) By default this option has no shortcut. On the right is a small add icon (a plus in a circle), click that.
16. When the "Bind new key to action" popup appears, press and hold CTRL and then S. It will show that you chose CTRL+S. This is good. Click SAVE.
17. Close the keyboard shortcut dialog.
18. Now test it. Ensure Lossless Cut is open and is the active application. Press CTRL+S. You should see the dialog open for "Detect Silent Scenes". This is good. This proves that the key binding in the app itself works. Close it.
19. Now test the new custom button you created on your MX Creative Console. Ensure Lossless Cut is still the active app. Press the new button on your MXCC (mine is labeled "Detect Silent Scenes"). You should now see the exact same "Detect Silent Scenes" dialog appear in Lossless Cut. Viola! You did it! Congrats.
20. If after this last step it's not working for you, be sure that you granted Options+ the proper permissions in your MacOS privacy settings. The above all depends on Options+ being able to have access to do all of these things.

Why the above works: Normally for any app, you'd just create a new custom button on your MXCC keypad for whatever function you want to perform in the app. But for some reason this isn't possible with Lossless Cut as it is today. While you still have to setup the MXCC button and create your custom shortcut within Lossless Cut, you ALSO have to use the kludge of creating the Smart Action in Options+, which serves as a "bridge" between you clicking the button on your keypad and the actual shortcut within Lossless Cut. I know, it's weird, but apparently it has something to do with the framework that Lossless Cut was built with. But at least this will work. You WILL need to create this same kludge for EVERY custom shortcut within Lossless Cut that you create, but the DEFAULT keyboard shortcuts within Lossless Cut seem to work fine without the kludge. Dunno why.

Hope this helps somebody! :)
