i have a very newbie question... and i hope you can help me out.
I shoot a 7 miutes video in 1080p. I then edited in screenflow. I exported at the highest resolution and i ended up with a 10Gb file.
Then i compressed it using compressor, using the H264 codec. The aspect ration remained the same. Although the final video looks pretty well on my computer, when i upload it to Youtube the quality is much poorer if i watch it on Iphone or Ipad.
