![]() I was surprised that both Episode and Squeeze were slower than average on both systems. I strongly recommend against using 2-pass mode in MPEG Streamclip. In both cases, I canceled the compression. In three different cases on both computers, it took more than 2 hours to compress a 4 minute movie. In 1-pass mode it was reasonably fast, but 2-pass mode was unstable. The latest version of Compressor is the fastest version yet, though running it in multiple instance mode caused some 2-pass compression jobs to fail.Īdobe Media Encoder was a solid contender, ranked third for speed in almost all tests. ![]() I suspect that it would be even faster running on a top-of-the-line Mac Pro. HandBrake seems to take fullest advantage of the Mac Pro architecture. If you own an iMac or MacBook Pro, Apple Compressor is fastest, with HandBrake second.If you own a new Mac Pro, HandBrake is the leader by a wide margin, followed by Apple Compressor.What’s the fastest compression software? Well, that depends… So, no image quality determinations were made. While this does not yield the smallest file sizes, a 10 mbps bit rate will yield excellent image quality in all cases. This test used the same YouTube compression setting for all systems and all tests, or as close as each software would allow. ![]() ![]() This article compares the speed between a new Mac Pro, a 21″ iMac and a 15″ MacBook Pro using Apple Compressor 4.2.This article examines image quality in the latest version of Compressor 4.2 when compressing files using the H.264 codec.This article compares the compression speed between Compressor 4.1.2 and Compressor 4.2.Here are the other articles in this series: ![]() We used the trial versions of both Telestream Episode and Sorenson Squeeze for this test. The software I used were the current versions as of today: This week, in my continuing series looking at video compression software, I want to compare the compression speeds of six different software when encoding files for YouTube using a new Mac Pro and a 21″ iMac. ![]()
