Review by Graeme Nattress
Video codecs - the clever software that compress and decompress your video footage for a variety of uses, come in many kinds. The two main kinds of codecs are those that achieve smaller files by throwing away information (lossy codecs) and those that preserve every bit of information (lossless codecs). Lossy codecs are very common in the professional video world. Digital video cameras use lossy codecs to achieve data rates that allow them to fit full quality video onto convenient tape formats, like miniDV for example. Lossless codecs, like the SheerVideo codec from BitJazz which is the subject of this review find the most use in a post production workflow where picture quality must be maintained as the video gets edited, effects added and passed from program to program.
BitJazz make some fairly serious claims for their SheerVideo codec, but fortunately, these claims are easy to test. They claim it will 'save both time and space in professional video and film production and archival, yet always maintains absolutely perfect fidelity.' I have traditionally used the Apple 'Animation' codec at 100% quality and 'Millions of Colors+' to create 'uncompressed' video, usually from 3D animation tiff sequences, in a production workflow to maintain absolute picture quality and the essential alpha channel for compositing work. It is in this environment that I decided to compare SheerVideo to 'Animation 100%'. In comparing the two lossless codecs, I also decided to try some lossy codecs to see what difference they made in terms of picture quality, file size, and playability. I have often used 'photoJPEG' codec at 100% quality in compressing 3D animation files for real-time playback on slower machines or for smaller file sizes, and I was curious to see how Apple's new Pixlet codec would also perform in this environment.
The speed and file size testing consisted of compressing a 200 frame tiff image sequence. The resolution of the tiffs was 960 x 540. I used an 800mHz 17' LCD iMac for the tests, compressing from and to the internal hard drive.
Lossless Codecs
200 frame 1/2 HD (960 x 540) movie, to SheerVideo 56 seconds, 121MB
200 frame 1/2 HD (960 x 540) movie, to Animation+ 67 seconds, 223MB
Lossy Codecs (for comparison)
200 frame 1/2 HD (960 x 540) movie, to Pixlet 91 seconds, 39MB
200 frame 1/2 HD (960 x 540) movie, to Photo-JPEG 46 seconds, 31MB
It's pretty obvious from the figures that both of BitJazz's claims about their SheerVideo codec are backed up by these results. It was the second fastest codec in the test, knocking 11 seconds off the time to go out to Animation+, and produced a file just over half the size.
I decided to examine the lossy codecs as an experiment because they're not directly comparable and they don't support alpha channels. It's also useful to see how they perform in terms of picture quality as compared to lossless codecs. To test for picture quality I used an old After Effects trick where you place two clips on two tracks, and put the top clip in difference mode. Any differences in them will show up as colour on a black background. The brighter the colour, the more the difference. To make it easier to see the differences, I also used a levels filter on an adjustment layer to brighten up the colours and make them more visible.
In the After Effects test, the SheerVideo codec proved to be totally lossless, showing no differences at all from the Animation+ 100% compression. Given that SheerVideo is producing files of nearly half the size, this is an excellent result and validates Bit Jazz's lossless claim.
Again, as part of my experiment, it's interesting to see how the lossy codecs compared. Visually, they both produced excellent results, very similar file sizes, although the photoJPEG was twice as fast as compressing as Pixlet, which was the slowest in the test. The photoJPEG also played back a lot smoother, showing that Pixlet needs a lot more processing power to work effectively. However, in the After Effects difference test, the photoJPEG produced much superior results compared to Pixlet.

Getting back to SheerVideo, I found the installer quick and easy to use, and registration was easy. Passport photo booth mac download. Most importantly, the SheerVideo codec has a free 'Reader' so that you can play back SheerVideo encoded movies on any Mac without having to buy another copy of the codec. The codec is also easy to use. When exporting using the SheerVideo codec, you have the option of letting it pick the most appropriate variant according to it's analysis of the source video, or you can choose from RGB[A] and a number of YUV options.
With a bootable Ubuntu USB stick, you can: Install or upgrade Ubuntu, even on a Mac. 2 days ago I created a bootable USB with Xubuntu iso (actually made it on a Mac with BalenEtcher), but I never replaced my Ubuntu so now I want to free the USB from being bootable. I followed the standard steps, located the disk with fdisk -l. Mac format usb for ubuntu iso.
It's hard to review a product like SheerVideo because there's so little to criticize. They have the free reader available and they are working on PC and Linux versions, so compatability will soon no longer be any issue at all, and the codec performs flawlessly in testing, reducing file sizes and time to compress by a significant margin. I recommend SheerVideo to anyone who is currently using the Animation codec in their workflow.
