16:9 masking quality problem

Many times I letterbox my 4:3 content with a 16:9 mask in Premiere Pro. Here lies the problem, whenever I change the position of my footage to better fit in the 16:9 mask, the footage always looks slightly degraded, very small but infact their. Ofcaurse I render but the problem Is still their.

If I put the 16:9 mask on top and don’t touch the footage it looks great, but as soon as I go to motion and change the position it always looks a little rough.

Does anyone know a solution for this.

Thanks in advance.
 
Hi Genesis.

Funny you should post this. I just experienced the exact same problem myself. I wondered why the footage looked a little "soft".

I'll keep you posted if I find a solution. Perhaps you can keep me updated as well? It may well be a issue of just exporting the repositioned footage as an AVI file, bringing it back into the project, and then placing the 16x9 mask over top.

We'll see what happens...

I've ran into this too. Sometimes i found a "sweet" spot where just the right position would look fine but one pixel either way and it would degrade again. I wonder if there is a better fix.
 
Hey there.

Ok. I got it to work, using the "sweet" spot idea. Thanks Jeremy!

Basically Genesis, when you reposition the image under Position in Effects control, you have to nudge it one way or the other until the image comes into sharp focus. This is what Jeremy means by the sweet spot.

For example, on the x-axis, position 224 & 225 might be soft, but at 226 the image comes into sharp focus.

Alternatively, position 223 and 222 might also be soft, but at 221 you once again have the image coming into sharp focus.

You just have to play with the positioning, nudging here and there.

Hope this makes sense. It made a big difference in my project today.

Have a great evening.

Wow, the sweet spot idea does indeed work. Thanks allot for the help guys. Such a simple solution, and so many months of agony trying to find a solution.
 
You must be careful and move in two line increments, or you will trigger a forced recalculation of the interlaced structure ... which will generate an essentially half-resolution file, in my experience.

Move from even to even, from odd to odd.
