I can confirm. However if start dragging the play back icon in the movie clip editor a couple frames it will start to work when you play the animation but very slow (not real time) so I believe we have a couple factors here.

Hey @yellowfoxz,
this is intentional, the Movie Clip Editor only starts a playback if the mouse is inside it. The play button is in an other editor (Timeline), so pressing play button will never start the playback in the Movie Clip Editor.

Thanks for the report, but no bug here :)

''this is intentional, the Movie Clip Editor only starts a playback if the mouse is inside it.'' it does not work ! i need to drag in movie clip.
so why using alt + a the playback working in movie clip, but when pressing playback button it does not work.... if you hover mouse on playback button and it has short cut alt +a right?

Alright let's start from scratch:

  • Blender's interface is divided into several subwindows called Areas or Editors pasted_file
  • The area where the playback buttons are in is called [Timeline ]] and is (more or less) independent from the [ http:*www.blender.org/manual/motion_tracking/index.html#movie-clip-editor | Movie Clip Editor
  • Decision was made (for good reasons) to only start the playback in the Movie Clip Editor when the mouse is inside it's Area
  • So as the Timeline and the Movie Clip Editor are two separate Areas/Editors, using the playback buttons means the mouse is not inside the Movie Clip Editor -> the playback in the Movie Clip Editor is not triggered.
  • The only way to trigger the playback of the Movie Clip Editor is by pressing Alt + A while the mouse is inside the Area

As I said, everything works as expected, even though I personally think there could be better ways to handle this on the UX side, but that's a different story (and no bug at all)

So I hope it's a bit clearer now what's going on here and what I mean. For further info I'd suggest having a look at our new Blender Manual .

@Blendify, not exactly sure what you mean, but if I understand correctly, what you describe happens because we have to prefetch frames, meaning we have to load them into RAM. Once every frame is prefetched, the playback should be smoothly. Prefetched frames are indicated by a brighter blue in the Movie Clip Editor timeline (the blue bar on bottom of the Movie Clip Editor, don't confuse it with the Timeline Editor ;) ).

Alright @JulianEisel I get it now i found a bug with loading it into ram that I will open but do you think that we should have the frame speed in the corner like in the 3d view port and VSE

No, that's something different. Once all frames are in RAM the playback should be in realtime (in most cases) meanig it is constant. It wouldn't make much sense to add a FPS display IMO. This is Movie Clip Editor 101, so most people already learned this after working with it for several hours.

Hi All,
@JulianEisel this is IMHO bug. When you press play button, then all animation windows just play (NLA Editor, Curve Editor, Sequencer, etc.) Only Movie Clip editor (type of view: Clip) just do not. Where is bug? I guess it is in file screen_ops.c at line 3395. I'm attaching patch: movie_clip_editor_play.diff

Best Regards,

Jiri

Just stumbled over this task again, @jiri, see #47815.

Thanks you @JulianEisel for pointing at right task.

Have anybody considered to change default blend file and enable playback of Clip Editors in Screen: Motion Tracking. IMHO it would make sence to enable playback in this screen.
