What I'm trying to do is to show part of clip and then start reversing on it...
So i made a key frame and add a "speed remapping" effect, slow the video, then i duplicate that video, and everything to this point is fine... the video start normally, goes to the speed of zero, then slowly back to normal speed in reveres.
Now i want to do the reveres in higher speed, to the beginning of the video... so using trim tools, i extend the reversed video to the very beginning, and here's the buggy part: I drag the "speed remapping" up, to speed it up, it get speeds, but the issue is, it adds from the begin of reversed clip not the end... and it cause my two clip to goes out of sync... it slows down in one frame, and start to speed up in a totally non related frame.
How to make it extend on the end point
Okey, Here's a normal timeline with some marker to show the effect... So think about this, as our begin state:
No i add another marker at the end, and start changing speed, as you can see the end of the clip got shorter, but our previous marker are same, it mean it fill the shortage from the end of the clip (cut from end)
Now i undo to our begin state and reverse the video clip
You can see the begin state of reversed state
Now i add a marker at the end, same to what we did with the first video... and start speeding up the video, as you can see this time our existing marker are moving, and it adds frame to the begin of clip not the end
Now here what i have, this little guys in here suppose to show a part of event which i important to me, then slow down to freeze, then reverse and maintain the speed, then goes to higher speed to the very beginning of the movie
But when i add/change the marker, instead of add/remove frames from the end of second clip, it take them from the start, and cause those two clip (specific frames) goes out of sync. it end at some place, and start at somewhere totally not related
