When we first saw the news of the Digimetrics Eos plugin for Final Cut Pro we thought 'nothing new' as it has been done before. Today a video for the Eos audio 'legaliser' was brought to our attention, so we thought we'd take a quick look at both.
Broadcasters will find any reason to reject a tape or file these days file for transmission. Gamut errors have been a particularly annoying reason for failures over the past few years. Sometimes watching the 'scopes isn't good enough, the internal ones in FCP aren't great and shouldn't be relied on for final mastering.
So what can you do to make sure your project that you've spent weeks on gets the thumbs up from your broadcaster? You could run it through an external 'legaliser' or you could look to software to do the job for you.
Digimetrics have brought out two plugins for Final Cut Pro that will make sure that your video and audio levels are within specific broadcast standards. First of all it is a bit confusing to call them 'Eos' - they have nothing to do with Canon's DSLRS! Secondly pricing is a little high for the FCP ecosystem at $299 for each plugin. Toolfarm has had promotions running on both these plugins so we would check there first.
Digimetrics has demo videos of both the video and the audio legalisers. We should also point out that broadcasters can reject a programme if it fails a Harding test. Kanye West's video 'All of the lights' has been flagged as particularly bad. (Since removed) The Eos plugin will not fix flashing pattern problems.
In regards to Color Gamut, Eos offers the ability to set limits for measurement and correction (and, by default, correct gamut using AutoFix) relative to EBU R103 in several methods:
- Percentage of legal limits
- Millivolts (mV)
- IRE (absolute value adjusted to 0-255)
You can choose to measure gamut against ITU color standards BT.601 or BT.709, or define your own custom color space using the Y', Cb' and Cr' coefficients for the RGB components.
Measurement and correction results are provided in an XML-based report, showing which frames are out of gamut, and if AutoFix is enabled, which color components were adjusted.
Safe Title/Action Area overlays are provided in the preview window for:
- NTSC 4:3 and 16:9 (525 line raster)
- PAL 4:3 and 16:9 (625 line raster) where applicable, overlays for 14:9 also provided
- 2k/Digital Cinema
using the following standards for measurement:
- SMPTE ST-2046-1
- SMPTE RP-218
- ARIB TR-B4
- ITU-R BT.1379-2
- EBU R92
- EBU R95
