I spent the morning editing a sequence - fixing the audio in Soundtrack Pro and then color correcting and rendering.
Everything's fine, except when I export it, the dimensions are incorrect. I thought it was an exporting problem, but I realized that there is something wrong with my sequence settings.
At full resolution, each of my clips are viewed at 24% (to fit the screen). The entire sequence dropped in quality, and is viewed at 74% in order to be the "same size" on my screen as the 24% clips from my camera.
Also, my other sequences that work fine don't display black letterboxes within the video; they are simply cut off of the frame. In this problematic sequence, there are black stripes at off-frame areas in other sequences.
I tried imitating sequence settings, but it didn't work - the entire clip shrunk in size, so that on the viewer, you see the video in a small box within a big black square.
I'm unable to identify the exact problem, and I understand it might be a bit misleading. But any information would be appreciated.
Also, I tried copy and pasting clips from this sequence into another one that worked; the clips are still in poorer quality and at a different size
In what format was the footage captured?
What are your sequence settings? (Press CMD+0 in your timeline)
What settings did you use to export?
If the answer to the first question differs from any of the others then you will have identified where the problem arose. Let us know and we can suggest a solution because at the moment there isn't enough detail to do more than make educated guesses.
