Can't scrub movies in finder

Yes, I can also confirm this is no longer working in High Sierra OS. Scrubbing Video in Finder using Column View is such a critical feature for me. (quick way to filter through 100's of motion detection security videos). For others that are confused or have questions on how this used to work, here is a quick video on this lost capability:

I am very surprised at this. Never seen it. Probably some add-on, as dialabrain says.

Note: just in case there is a vocabulary issue - by the preview pane, I mean something like this:

I'm able to scrub a movie in the column view.

However, it's not all movie files that will do it. Only those that show the play button when the cursor is over the preview image will scrub:

I would guess that abut 2/3s of my movie files do how scrub. Have no idea why.

Yes, it has to be the right format. MKV files won't do it but if it plays in Quicklook you should be able to scrub it.

Apparently not in High Sierra. You can always let Apple know you would like the feature back.

Feedback - macOS - Apple

They won't answer but if enough users mention it, they might consider it.

I don't actually know if it's been removed or it's a bug. Send them a note. 😎

Yes playing still works but I've always been able to scrub the movie with the mouse. Scrubbing is the process of moving quickly forward or backward through the movie with mouse control on a Mac.

Scrubbing where? Right over the movie icon in the Finder (in icon mode)? On the preview (in column mode)?

I can play a movie right from the preview in column mode (by pressing the little play button in the middle), but I cannot scrub as you say.

I can scrub a movie in QuickLook. I don't remember ever being able to scrub a movie in the preview pane of the Finder.

I had this question as well; thanks for posting this problem

I'm glad you posted because I've been trying to figure out whether it was an old plugin that I added long ago or some glitch in Mac OS. This was the only search result where I could confirm that others had noticed this problem and that it was not a plugin problem. It still works in QuickTime player — just not in Finder.

I submitted feedback to Apple. Hopefully, they fix it because it was extremely useful for me (and it looks like others as well).

Not just movies, but even documents like pdfs and others. The scroll bars show, but scrolling doesn't work anymore. If i click on the scroll bar and move it, scrolling works, but not using the trackpad or the mouse wheel.

Could this be touch bar related, i.e. you're supposed to use the touch bar instead of the touch pad? Can anyone without a touch bar on High Sierra check, whether the touch pad works for scrubbing? I don't see what good disabling the touch pad option should do, though.

It looks like apple either took it out or forgot to put it in because scrubbing videos with 2 fingers on the trackpad still works in quicktime and VLC that I've been able to test. I'm currently on 10.13 and hope they put it back in a future update.

Not sure what you mean by scrubbing in the Finder... Quicklook still works (press space).

Playing an AUDIO file right there in the Finder still works:

Just so I'm clear, by QuickLook I mean…

I don't remember if Perian or Flip4Mac would allow scrubbing directly in the preview pane. Been too many years since I've used them.
