![]() ![]() Version 2.0 marks an immense milestone in the development of QTAKE, with the new licensing model and substantial under-the-hood improvements. The most important new features in QTAKE Pro v2.1 are listed below: With the increasing demand for multi-camera 4K capture and playback as well as High Dynamic Range support, real-time rendering requires every bit of processing power from available hardware. Version 2.1 brings another major update to QTAKE Video Assist software, this time focused on performance. Thank you for taking your on-set video services to a new level. In addition to impressive video assist and DIT software, QTAKE ecosystem includes QTAKE Server and QTAKE Monitor applications that provide unmatched on-set, and cloud-based collaboration using low-latency streaming, independent playback, and metadata editing. QTAKE Pro then provides the fastest and most effortless dailies export and sharing. QTAKE Pro offers unique stereoscopy support with industry-standard 3D output in live or playback mode and various 3D alignment modes using PLUS 3D VIEW.Īfter the magazine is ejected from the camera, you can import RAW files into QTAKE Pro and match them to video recordings to preserve all metadata and on-set color grading. VFX supervisors around the world rely on QTAKE Pro to perform real-time on-set compositing with support for motion control and motion-tracking systems, GPI triggering, and CGI integration. The ability to capture metadata from a camera and other on-set devices makes QTAKE Pro an essential part of the workflow that fills the gap between production and postproduction. It provides a unique database, customizable to fit any project, real-time image processing up to 8K resolution, multi-camera support, on-set color grading, live editing, and much more. The main purpose of any video assist system is to provide immediate playback for the crew, but QTAKE Pro goes far beyond that. It logs, captures, plays, edits, and processes digital cinema camera’s video output and RAW recording. If the results weren’t equal, microbenchmark would return an error message.Īnother great feature is the integration with ggplot2 for plotting microbenchmark results.QTAKE Pro is the most advanced software designed and developed for video assist and DIT professionals. We used the function argument check to check for equality (up to a maximal error of 1e-12) of the results returned by the three methods. # expr min lq mean median uq max neval cld The most recent development version of microbenchmark can be installed from github:Ĭheck_for_equal_coefs <- function(values) , Interestingly lm is by far the slowest here. ![]() Here, the meaning of elapsed, lf, and sys.self is the same as described above in the section about system.time, and relative is simply the time ratio with the fastest test. # test replications elapsed relative lf sys.self I installed the development 1 version of the rbenchmark package from github:Ĭolumns = c("test", "replications", "elapsed", Additionally the returned results are conveniently organized in a data frame. For example it requires just one benchmark call to time multiple replications of multiple expressions. However it adds a lot of convenience compared to bare system.time calls. The documentation to the function benchmark from the rbenchmark R package describes it as “a simple wrapper around system.time”. ![]() Different operating systems will have different things done by the operating system. The operating system is used for things like opening files, doing input or output, starting other processes, and looking at the system clock: operations that involve resources that many processes must share. “User CPU time” gives the CPU time spent by the current process (i.e., the current R session) and “system CPU time” gives the CPU time spent by the kernel (the operating system) on behalf of the current process. Well, clearly elapsed is the wall clock time taken to execute the function sleep_for_a_minute, plus some benchmarking code wrapping it (that’s why it took slightly more than a minute to run I guess).Īs for user and system times, William Dunlap has posted a great explanation to the r-help mailing list: But what exactly are the reported times user, system, and elapsed? :confused: ![]()
