Picture Quality
figure 1: The Picture Quality Settings
These settings (figure 1) determine how long Snappy will spend sampling the video source that it will use to make your image.
There are two factors that affect the quality of the final image: the number of frames sampled and the resolution of each sample. The more frames that Snappy is able to sample, the higher the color accuracy and lower the video noise will be. The higher the resolution of each pixel grabbed, the better the picture detail will be.
Moving Video
This is Snappy's default setting. Using it instructs Snappy to sample one field of the incoming video source. This is the shortest possible time (1/60th of a second) that Snappy can spend sampling the video source. This is the setting you must use if you want to snap from any incoming video source where the images are moving, such as tapes, laserdiscs or TV tuners.
To see how to best use the still video modes, follow this link:
Still Video
Use this setting if you are snapping from any still source and you want to get the fastest results. Snappy will now use a two-field sample of the incoming video, and sophisticated image processing software which will result in an enhanced image.
High-Quality Still
Use this setting if you are snapping from any still source and you want to get even better results. Snappy will now take a four-field sample of the incoming video. The processing time for this setting is roughly twice as long as for the normal still setting.
Highest-Quality Still
This is Snappy's highest-quality setting. Snappy samples eight fields of the incoming video to make the image when you use this setting. When you select the 1500 x 1125 option, Snappy will automatically set the Video Source option to Live Camera if it is not already set that way. This setting takes the most time to process and delivers images with more than twice the resolution of any other capture product ever created.
