Long time user. CS6 been working great. DELL PC wn 7.
Today finishing 40 minute documentary.
2 short clips out of hundreds rendered green instead of normal.
Checked and both had the horizontal flip effect on them.
Turned that off on both clips and they rendered fine.
Was rendering master out to H264 720p codec.
DSLR Cannon source footage.
Very strange. But was able to fix. Still why that effect had that result
I don't know.
