Bandi Capture LibraryBandi Capture Library
Benchmarks - compared to FRAPS
FRAPS is different to BCL. because BCL is intergrated into main application but FRAPS captures video file externally.
File size
See below table. This is captured video file information.
BCL produce much more smaller video file than FRAPS video. FRAPS video file is up to 20 times bigger than BCL video file.

Video Quality
Bandi Capture Library uses a lossy compression, unlike FRAPS uses a lossless one, is a little degradation of the quality.
But to the naked eye, almost impossible to distinguish the difference. See below. (This image is from captured video file, and converted to PNG format)
