Hi,
It appears that if 'Quantize to Frames' is turned on, and you add a marker on a frame boundary (in the trimmer), the EXACT location of where the marker is added depends on HOW you got to the frame boundary.
If you click on the frame boundary with your mouse, or step to the frame boundary with the cursor keys from the right, it behaves as expected.
If you step to the frame boundary from the left with the cursor keys and then drop the marker it seems that it actually gets dropped a FRACTION after the boundary, potentially screwing up your editing (which is how I found this, I had errors on my scene boundaries with overlapping). This 'fraction' isn't visible at all even if you zoom in all the way.
To prove this try the following:
Test 1
------
Turn 'Quantize to Frames' on to ensure that you're snapping to the frame boundaries. Create a generated media solid color (red) for exatcly 5 frames.
Then create a yellow 1 for exactly 5 frames and snap it to the right of the red clip.
Render this (I did as NTSC DV) 10-frame Red-Yellow clip. RRRRRYYYYY
Now import the clip into the trimmer.
(Quantize to Frames should still be still on)
click on frame boundary 00:05 with your mouse (don't use the cursor keys!) and press 'm' to drop a marker.
Select the left clip (00:00-00:05) and drop it onto a video track starting at 00:00. Press ctrl-end to go to the end of the clip. In you preview window you should see black (since there is no frame 6) - You get exactly 5 frames of red and nothing else.
Now delete that clip from the track. Go back to the trimmer & delete the marker at 00:05
Test 2
------
In the trimmer drop your cursor at 00:07 and use the left cursor key to move you to exactly 00:05 and drop the marker. Move that left clip to a video track and go to the end -- you'll see black again, exactly the same as before.
Now delete that clip from the track. Go back to the trimmer & delete the marker at 00:05
Test 3
------
HERE'S WHERE IT GETS INTERESTING:
In the trimmer drop your cursor at 00:03 and use the right cursor key to move you to exactly 00:05 and drop the marker. Move that left clip to a video track and go to the end -- THIS TIME YOU'LL SEE YELLOW!
The only reason this can be is if the marker is extending even a millionth of a second into frame 6.
This is really wierd.
So, is this by design & documented or is it a bug? Has anyone else found this or had problem with bad edits?
Either way it's a pain in the butt to now have to think about how you got to where you were before you drop a marker. I don't know about you, but I think there should be 1 standard behavior regardless, so that a marker at 00:05 is the same no matter how it was dropped. (or have a different type of marker, pointing left/pointing right)
Thanks,
