Exporting to QuickTime DV-NTSC, MJPEG-A, MJPEG-B, or PhotoJPEG Prior to Encoding
If you have videos on your Non-linear editor that are destined for the web, exporting your videos as a QuickTime DV-NTSC, MJPEG-A, MJPEG-B, or PhotoJPEG prior to encoding will help you get great quality. DV-NTSC, MJPEG-A, MJPEG-B, and PhotoJPEG are all codecs found inside QuickTime on Non-linear editors such as Avid, Final Cut Pro and Adobe Premiere Pro.
Using this process allows you to then take your videos into encoding tools such as: Compression Master, Sorenson Squeeze Compression Suite, ProCoder, Flix Pro, Cleaner and many others. These encoding applications will produce files small enough for the web delivery.
When exporting content with these codecs in QuickTime it's mostly about the quality settings. The higher the quality setting the longer your export will take and the better your quality. For example, the PhotoJPEG codec at the highest quality setting of 100% is actually a 4:4:4 codec but if you bring down the quality setting to 75% Quality it becomes a 4:2:2 codec which is even better sampling than DV at 4:1:1. MJPEG-A and MJPEG-B are also capabable of producing 4:2:2 quality.
