Whenever possible we prefer to work with source camera files in the grade. 

Please upload or deliver a drive containing source camera media, an XML and offline reference file to NT COLOUR LTD Unit 112, Brickworks Business Centre, E2 8HD, London up to 24 hours before the grading session. 

XML/AAF 

·       Remove all media that is not to be graded. This includes hidden or disabled clips, audio and titles.

·       Collapse all tracks into one layer of video where possible. - Linear speed effects will translate but dynamic speed changes will need to be removed. Please extend the shot duration to cover the length of the speed change.

·       Nested sequences and compound clips must be un-nested.

·       Please supply one XML or AAF per timeline, do not consolidate multiple timelines into one file. 

QuickTime Reference

·       QT reference files must visually match the supplied XML exactly and be exported from the same timeline. This is the file that will be used to check the timeline has imported correctly.

·       This reference file can contain audio but please ensure the XML does not have any audio tracks.

·       A cut-reference QT can be supplied that matches the latest edit and include any effects or elements removed from the colour prep timeline.

·       Please keep any dailies colour baked into the QT references.

·       Preferred codecs are ProRes 422 LT or ProRes 422 Proxy. H.264 in .mov or .mp4 is also accepted.

·       QT Reference file must contain burn-in source timecode and filename.

Conformed Sequences 

·       While working from Source files is our preference, sometimes the budget/time does not allow it. Conformed sequences are acceptable as ProRes 4444, Uncompressed Quicktime. DNxHR equivalent and 10bit DPX image sequences are also acceptable. 

·      This file should be at the same resolution and frame rate as the final deliverable, e.g. 3840x2160 @ 25 fps. 

·      Please render R3D media at full-res decode in IPP2, RedWideGamutRGB and Log3G10

·       Please remove any transitions such as dissolves or dips to/from black

Source Drive

·       Please consolidate media to a single drive where possible.

·       Should be clearly labelled with the project name.

·       Please include any power cables.

·       Please provide drives with USB 3.0 and/or Thunderbolt connection.
