So i've been editing a video for about a month - it's just a fun project, so I spend like a few hours on it here and there. Anyway, recently, when I send to timeline, and then try moving that clip back or forward, I get the render red line. Now, my sequence is definitely set to the same as my footage, there's no problems there. I have noticed, too, that if i unlink the clips, this little red box appears on both the audio clip and video clip, with a numeric value which seems to correlate to the positions of the clips, in relation to where i first overwrote them to the timeline.
I have a screen shot here, which you can probably understand way better than that explanation! :P
I've deleted the audio in that screen shot, but both audio clips had that same red box with the numbers in.
Could someone please tell me what to do to get rid of it, please?
I hope it's me being stupid and missing something really simple!!
