Summary0000329: The inversion of the frame-by-frame scrolling in mixers starts with a frame in the wrong (old) direction.
DescriptionIf I reverse the direction of the image/image scrolling (with the jog or ctrl 4-1 keys) the mixers images first move in the wrong (old) direction for 1 frame, before moving in the right (new) direction.

No problem is present in the case of the image in the composer or with the one in the viewer.
TagsNo tags attached.

GG had a chance to work on this for a few hours yesterday. We definitely can see a jiggle frame problem. He looked for a simple/easy fix but realizes that the real fix would be to rework the playback engine to correct some small design flaws leading to this type of problem. Currently he is going to attempt to do this after this month's builds early in November so as to get early on testing done. Will update later.

OK, I will test that. I found it in my marked private folder.

I observe the problem with DNxHD files (made from HDV sources) in non-Proxy mode.

Phyllis, I sent you directly several months ago, source files and the xml of a DNxHD editing test with mixers. You can see the problem when you play it in non-proxy mode.

The test folder was called "EX-EGO Test DNxHD". If you no longer have it, I can send it back to you.

We can see something a little strange with an occasional jiggle. Not sure what is going on yet. The file we tested had frame numbers on it of 1, 2, 3, 4, ... and when reversing using either the jog or 4 we do see the same frame repeated when reversing but never see it go 1 frame forward before going backward.

Still testing here to at least try to explain the jiggle.
