Short description of error
Blenderplayer extreme zooms in when playing rendered animation.

Exact steps for others to reproduce the error

play_anim.blend690 KBDownload

Open the .blend file above and:

  • may be you want to change the output file location
  • do ctrl+f12 to render the animation
  • when the animation is finished rendering play it (ctrl+f11)

Notice that blender player doesn't play according to your camera position, somehow the player is zoomed in, notice Suzanne is cut out. But VLC can play the animation pretty well.

It works fine for me, however it seems like the blender built in player lacks scaling, so if I playback a 1080p video on a 1080p monitor, I have to make sure that the player window is fullscreen or the video will be cropped.

@Brecht Van Lommel (brecht) is this bug or not?

This is a problem we didn't have in Blender 2.79

For the record, this isn't a blenderplayer, this is animplayer (confusing, but historically blenderplayer is the game engine thing).

For me the behavior between 2.79b and current 2.8 is exactly the same. So if the issue is about lack of scaling/scrolling in the animplayer then it's just a missing feature than a bug.

@Erick Tukuniata (erickblender), does the video play correct for you if you open in in a clip editor? Does it play correct if you maximize the player window?

@Sebastian Parborg (zeddb), did you verify that the 2.79 behavior is different for you?

@Sergey Sharybin (sergey) I did try it. However I forgot about one silly thing. 2.79 renders the animation at 50% resolution per default. So I just rendered out the default cube scene and played it back.
I'm using a tiling WM, so the new window opened up at 50% of my screen so the video was show as full. I then toggled the window fullscreen and the blender player scaled the image.

So I thought that scaling was working. And because the reporter said that it should be working in 2.79, I didn't think I had any reason to doubt that after doing this quick test.
Looking at it again now it seems to only be able to scale up and only integer scaling, so my bad.

Did some fixes for zooming. Now Ctrl +/- can be used to zoom out the image which doesn't fit.

This is not ideal at all, but for smoother experience the player needs to have some internals redone (there is a feedback loop between zoom level and window size, which is tricky to deal with).

Hello Sergey,

does the video play correct for you if you open in in a clip editor? Does it play correct if you maximize the player window?

Yes it does play correctly. But the problem is that with a heavy scene (high multires. objects), animation plays poorly in Blender viewport, my workflow is: crtl+12, go for a short stretch till the render(play blast) is finished and crtl+11 to see if there some stuffs (timing and spacing) to fix then fix and again ctrl+12 and so... This bug is making the all process painful.

I tried this and it zoomed out only once and then nothing here is what i got after ctrl-

Suzanne is still cropped. :(

I don't think current builds from buildot do include my fix from today. Without it it will not work indeed.
Do you mind testing with the next build? (will be available later tonight. So maybe wait for until tomorrow, give it a test, and let us know how it goes).

I build it ;) I will check tomorrow as well :)

Interesting. Can you try resizing window manually to a smaller size and see if that allows you to zoom out more?

Could be something OS related, was only testing on Linux. Can fire on Window box tomorrow and see how that works.

Since our Docta mentioned the word "Interesting", this made me question everything i was doing, so rebuild Blender again and now it is working pretty well after rendering, i did ctrl+11 and ctrl- ( works many times now) This is the new render

For me you can close this task. Thank a lot :)
