Resolution Specifications: JFIF Interlaced
Avid JFIF resolutions use a simple notation ( x:1) to identify the level of compression. The value
of x indicates the level of compression that is applied to the image data. For example, a 3:1
compression ratio compresses the original data to one-third of its uncompressed size.
A lower compression ratio (a lower number to the left of the colon) results in better image
quality but requires more drive space to store the captured media. A lower compression ratio
might also require drive striping to keep up with the high volume of data.
The following table provides information about the Avid resolutions for interlaced media (30i
NTSC and 25i PAL projects). Field size does not include blanking or VITC lines.
