With the enormous range of options available when choosing delivery standards for video and sound, it can be a relief to receive a delivery specifications document. This video explains what this is, and how it helps you avoid making mistakes when delivering content for multiple clients and multiple display mediums.
- [Instructor] Broadly speaking,…if you're working professionally producing media…or even if you're preparing home videos…for a distribution system like YouTube,…you're going to be producing content…for somebody else's needs.…A good delivery specification will tell you…the ideal frame rate, field order,…or to use progressive full frames, the frame size,…pixel aspect ratio, bit depth, color mode,…number of and allocation of audio channels,…and we'll cover more on that later, the data rate,…which is usually described in megabits per second,…and that means millions of bits per second, and the codec.…
All of this should be specified…by the person you're delivering the media too.…Very often these specifications will be set…by a media management system your client is using…or by the distribution method.…It's useful to ask for this information…during pre-production,…because then you can choose camera settings…that minimize conversion and make it easier…to deliver to these standards later on.…Often, many of these settings can be changed…
Get ready to remove the mystery behind terms you've encountered. If you work in a creative profession, this can enhance your command of the tools you use. Learn what a pixel really is, what color channels are, and what audio frequency is. Discover how color channels, bit depth, and video frame rates work. Find out the difference between codecs and file formats, and how compression is involved. By the end of this course, you'll know how to answer common client questions—like, whether a logo should be supplied in vector or bitmap form, and more.
