Summary0001112: In 2.11.16, using crop buttons changes preview position

Just noticed this in 2.11.16 running in 10.6.8 - when I change crop values, the preview slider position changes with the crop values.

Don't worry, testing with the current MacOS 10.12.5, no such bad behaviour. :-)

Doesn't happen anymore in 2.11.19, not even under 10.6.8 ;-)

Hmm... it still happens - even in 2.11.22 and Sierra. The question is, what triggers it to appear...

I just created a new project to convert an older interlaced 4:3 source. And while trying to crop uneven frame borders, I see the preview slider jumping large portions whenever I activate one of the crop arrow buttons.

Now that I have the effect again, some details:

  • the preview slider only goes forward, never backwards, no matter whether I increase or reduce cropping, makes no difference for left/right/top/bottom
  • it always jumps to the same preview positions, , that means, whenever I click on either of the crop dials, I always see the same pictures appearing in the preview window. As if the crop controls jump to the same positions in a sequence - even when I start from a different position
  • when the preview slider has come to the end of the content, no further moves
  • it is independent of the 'jump to selected content' checkbox
  • I can not slide the preview slider back to frame 1 manually, nor can I nudge it back to 00:00:00:00 - the only way to reset it back to the start is by checking 'jump to selected content' and the reselect content. I can then crop without the preview slider jumping, but see no picture (initial frame black). The moment I advance to the first non black frame, I get the crop-trigger-jumps behaviour again. This seems to be just a nasty false trigger of the preview slider position. I also still get the old issue of the filter/interlace setting not being visible immediately unless I temporarily switch forth and back between e..g. a color preset (e.g. from rec601 to rec709 and back to rec601.

It's not a show stopper, but it's a nuissance when I want to crop based on what I see, and when I actually change a crop value, my reference picture flips away. It doesn't seem to influence the DCP creation at all.

It also happens the same way when I insert numbers instead of dialing up/down.

In one of the recent test versions, I also noted the preview slider jumping when I had the video filter dialog open and switched filters. I can not say wether the issue is completely gone, as before, I couldn't reproduce it intentionally, usually it occured to me when I didn't think of it.

Should be fixed by the same commit; do re-open this bug if you see it again.

Was it a Mac specific issue? I work and test mostly on a Mac, can't remember if I ever experienced it in windows. Seems few other people complained about it. It only bothered me when I tried to crop visually, but my reference picture was always flipping away with an up or down click.
Other than that, it's not an actual show stopper. Just weird.

The bug that was fixed here was triggered by doing a slider position drag and then doing some cropping. Same on all platforms I think.
