Is there any way to keep playing while moving the scrub marker?

Use this autohotkey script. Will only work when you right click the grey area on time line, so you could left click when you don't want to play after repositioning. Credits to Taran from LinusTechTips for this script, I just added L key to it after repositioning.

;THIS IS A GREAT FIRST SCRIPT FOR AHK NOOBS! IT WORKS WITH VERY LITTLE SETUP. JUST READ THE STUFF BELOW! YAY!

; NOTE THAT YOU MUST ASSIGN \ (backslash) to "Move playhead to cursor" in Premiere's keyboard shortcuts panel!
; YOU SHOULD ALSO ASSIGN CTRL ALT D to "DESELECT ALL"

;NOTE: I use the right mouse button for this because my current mouse does not have macro keys on it. I could use the middle mouse button, but it requires too much pressure to push down so often, and you have to be careful not to accidentally scroll it.
;But if you want to use a button other than the right mouse button, the script becomes a lot simpler. Scroll down to the bottom for that script.

;NOTE: This does not, and cannot work on the timeline where there are no tracks visible.

;That is color 0x212121, and last I checked, it shows up in many other places in premiere, not just that part of the timeline.
;The easy solution is to just fill up your timeline with tracks; have no blank space.

;---------------------------------------------------------------------------------------

;First, we define all the timeline's DEFAULT possible colors.
;(Note that your colors will be different if you changed the UI brightness inside preferences > appearance > brightness.)
;I used Window Spy (it comes with AHK) to detect the exact colors onscreen.
timeline1 = 0x414141 ;timeline color inside the in/out points ON a targeted track
timeline2 = 0x313131 ;timeline color of the separating LINES between targeted AND non targeted tracks inside the in/out points
timeline3 = 0x1b1b1b ;the timeline color inside in/out points on a NON targeted track
timeline4 = 0x202020 ;the color of the bare timeline NOT inside the in out points
timeline5 = 0xDFDFDF ;the color of a SELECTED blank space on the timeline, NOT in the in/out points
timeline6 = 0xE4E4E4 ;the color of a SELECTED blank space on the timeline, IN the in/out points, on a TARGETED track
timeline7 = 0xBEBEBE ;the color of a SELECTED blank space on the timeline, IN the in/out points, on an UNTARGETED track

;If you don't want to use Rbutton (the right mouse button), then you don't need to check for colors and things. This simplifies the script siginificantly.
;In the following script, You can change "Mbutton" to anything else. like "Xbutton1", or  even "F12" if you wanted.
;So, assuming you've mapped "move playhead to cursor" to the \ key, the problem is that it fires once, waits 1 second, and only then does it continue to fire.
;that's why I use a loop - to send constant keypresses, for a smooth experience.

Good point but we are at adobe premire 14.2 and we still dont have this basic feature yet.. Every other video editor does it...

I also really want this feature. So, here is my feature request, I think it outlines the preferred behavior. But, I would also like other thoughts on each of the use cases. And without a forum post, there really is no room for discussing features anywhere....

I am posting to this thread because it was the first google return.

--------

How would you like the feature to work?

--

This feature should be implemented as an OPTION, not a forced change for all users. A checkbox/mark labeled: Continue playback after seek.   (or something of that nature)

In any of APP's timelines:  If the video or audio is currently playing, and the playhead is moved independently of realtime playback, playing should continue as expected.

Use cases (all while in 'play' state):

1.No interaction: playing continues until end, or out point. Identical to current behavior.

2.Using keyboard 'back 1 frame': This moves the playhead back 1 frame when the signal is received. So, the actual result will depend on keyboard type (ps2/usb), repeated key rate (OS setting), and playback framerate. i.e. if playing @ 60fps and key repeat rate is only 30 times per second, would have the effect of halving playback speed.

3.Using keyboard 'forward 1 frame': This moves the playhead forward 1 frame when the signal is received. Effectively increasing playback speed for the duration of the key press.

4.Using mouse to drag playhead: this would behave similarly to how mouse behaves now. Except, if we were in a play-state onDragStart, then re-enter play-state onRelease.

5.Using UI buttons: Clicking buttons for 'In', 'Out', previous, or next frames, should jump the playhead to any of those positions, exactly as it does now. Except, if we were in a play-state onButtonDown, re-enter play-state on enterFrame.

Why is this feature important to you?

--

It saves time and an innumerable amount of repetitive user actions (hitting space bar over and over and over). Ideally, I would be able to enter a play-state, that would allow me to quickly make playhead adjustments, and set in/out points without have to hit another button or key to go back to what I was already doing, playing through a video.

--------

Hopefully is describes what others are looking for. But, unless people actually request the feature, it will never be implemented.

Megaman1571  wrote I'm coming from Vegas Pro 13, and in vegas when you move the playback head, the video doesn't pause. Is there any way to replicate this in Premiere? I find it really hard to get used to it pausing all the time.

As a longtime Premiere user this would drive me crazy.

I dont like this in FCPx either.

Premiere Pro does not assume anything, which is good.  It will do only what you tell it to do, so if you want to continue playing, you need to tell PP to do so by hitting the spacebar again.
