Project Properties Frame Rate Undo Bug - Fixed in VP14

NickHope wrote on 12/19/2014, 11:50 AM

I have found a bug wherein a frame rate change in the project properties does not undo correctly.

I am seeing this in Vegas Pro 12 build 770 and Vegas Pro 13 build 428.

Please verify this for me before I report it to check it's not specific to my set up, and let us know what build of Vegas you're using and what version of Windows.

To reproduce:

1. Open a new project.
2. Set the project properties to the "HD 720-60p (1280x720, 59.940 fps)" template.
3. Zoom in and move up and down the timeline a bit with the left and right arrows on your keyboard to check that works.
4. Change the frame rate in the project properties to 29.970 (NTSC).
5. Edit > Undo
6. Zoom in significantly on the timeline with the mousewheel or other method.
7. Try moving the cursor backwards and forwards along the timeline.

When I do this, the cursor locks up or misbehaves.

And worse than that... I have the internal preference "Show Unquantized event start" and "Show Unquantized event end" set to TRUE. I am working on a 59.97p project. If I change the frame rate to 29.97p, some of the event ends are highlighted in red, which is expected because they don't line up with frame boundaries. However if I set it back to 59.97p (by using Undo) they remain red, and I also get the problem with cursor navigation as described above. The only way to fix it is to reopen the project without saving.

I also tried this by changing from 50fps to 25fps and got similar problems.

I verified after the Undo (changing frame rate from 59.94 to 29.97) caused the cursor not to move with the left and right arrow keys when zoomed all the way in. This was true on Vegas Pro 12 and 13 on both my machines running Windows 7 Professional 64-bit.

I found that I could zoom all the way out using the down arrow or the mouse scroll wheel and the cursor would move again but still not move when I zoomed back in past a certain point.

I also found that changing the frame rate in the Properties panel causes the cursor to move again even after the Undo. I didn't check Quantize to Frames.

I observed the same behavior in Vegas Pro 9, 10 and 11. I would never have found this issue (in fact, in all these years I didn't find it) because I wouldn't Undo changes in the Project Properties panels. I would go back to the Project Properties panels and change it.

Thank you John.

I am not seeing the problem with the cursor movement in VP10. However in VP10 I do see the problem of the event end showing as not-quantized after the undo.

I will submit a bug report.

It certainly seems like a bad idea to use undo to revert back to previous project properties.

It's not something I do often either, which is why I didn't find it until now.

This bug still exists in VP13.0 build 444.
