Video, audio and metadata quality assurance (QA) happens at many points along the production pipeline, but mostly falls into three broad categories: live signal, file check and compression quality. Drastic provides cost effective tools for each of these workflows.
Live Signal QA
Live signal quality assurance generally relies on dedicated waveform and vectorscope hardware that is single purpose and quite expensive. 4KScope provides a cost effect alternative for workflows that do not require constant monitoring and where there is a video I/O board available. 4KScope is available as an SD/HD/4K version, or as a pro version called HDRScope that supports signals up to 8192 x 4320. 4KScope provides a vectorscope, YCbCr waveform, RGB waveform, RGB histogram and safe zone picture in native YCbCr or RGB at up to 10 bits of resolution per component. 4KScope also has built in 608/708 closed captioning with text preview overlay and support for up to 16 audio channels.
If you only need SD/HD monitoring, you can check out sdiScope, an economical signal analysis tool with 2 channel audio support.
File Check Quality Assurance
videoQC is a suite of video and audio analysis and playback tools with both visual and automated quality checking tools. videoQC will take the media coming into your facility and perform a series of automated tests on video, audio and metadata values against a template, then analyze the audio and video. It includes metadata extraction, comparison and templating tools, intuitive charting of audio and video metrics, a full set of audio and video waveform/vectorscope/phase tools, db and PDF reporting, file to file visual comparison, and clipping and exporting tools. videoQC's automated server components can run headless (no interface) for analysis tools. Integration with Net-X-Code suite provides quality control for IP based workflows.

|MediaReactor has always included an optional PSNR check for compressed files. This capability has been broken out to make it available to the user. MRAnalyze is a command line tool that can perform PSNR, SSIM or MS-SSIM video comparisons between a source file and its compressed version. It outputs a CSV file with all the file information, a pass/fail and the comparison value for each frame, suitable for bringing into a spreadsheet for making charts and further analysis. Because MRAnalyze is based on MediaReactor, it natively supports all the file formats MediaReactor supports. It can still be used as a final check for MediaReactor translations, or it can be automated to check translations of any compression software.
