Unwrapping NotchLC MOV to NotchLC7th Frames

NotchLC is a lossy compression algorithm achieving data rate between 5:1 and 8:1 with mild perceived quality loss. Supported as of Delta 2.8+

NotchLC movies are produced by 3rd party tool (e.g. Notch, After Affects) exclusively in MOV-wrapped format.  Delta will attempt to render this format, but doing so is not advised for performance purposes (as NO WRAPPED CODECS are advised for performance in Delta.)

Instead, we provide a tool ‘NotchLCTo7th’ which unwraps NotchLC MOVs, extracts the frames from any LZ4 compression, and repackages each frame as a .7th image file in a sequence.  The actual image data is unchanged, so this process maintains exact source image quality, and is relatively fast in processing versus full image data rendering.

‘NotchLCto7th.exe’ is installed with Delta Server 2.8.7+ installation packages.  It resides at C:\Program Files\7thSense\Delta\Utilities\NotchLCTo7th

Compatibility

Windows 10/11
