Hi peoples. I have been playing around with the different formats and options you can make for saving the file with very mixed results. Which is the BEST calibration for a quicktime player? Is there any sort of options that I can customize to make the video look cleaner and less blocky? Thanks. 
If you export to QuickTime, the movie should not look blocky when the movie is not resized (QuickTime Window).
If you need to export to a higher resolution, you can change your project resolution in File > Animation Properties…
This will determine the size of the exported movie.
Thanks. Duuhhh. I hadn’t thought about the effect it might have when I put the player into full screen. Thats why it was blocky. Changed the size with much better results. Thanks so much!
