NEF in het kort
NEF
Convert to NEF when preserving Nikon originals or maintaining a workflow that expects Nikon raw files.
It is ideal for archive masters and non-destructive photo editing with maximum capture latitude.
MPEG-2 in het kort
MPEG-2
Convert to MPEG-2 when the target environment is DVD authoring, broadcast playout, set-top compatibility, or archive migration from systems built around classic MPEG transport and program-stream workflows.
It remains useful anywhere older professional or consumer playback chains still explicitly expect MPEG-2 video.

Why convert NEF to MPEG-2?
Convert to MPEG-2 when the target environment is DVD authoring, broadcast playout, set-top compatibility, or archive migration from systems built around classic MPEG transport and program-stream workflows.
It remains useful anywhere older professional or consumer playback chains still explicitly expect MPEG-2 video.
What changes when converting NEF to MPEG-2?
This conversion changes how the format behaves in downstream tools and delivery environments.
Quality profile changes from raw in NEF to depends in MPEG-2. Editability profile changes from high in NEF to limited in MPEG-2. Compatibility profile changes from limited in NEF to moderate in MPEG-2. Archival profile changes from strong in NEF to moderate in MPEG-2. Metadata profile changes from rich in NEF to moderate in MPEG-2. Delivery profile changes from limited in NEF to strong in MPEG-2. Workflow profile changes from source in NEF to delivery in MPEG-2.
Moving to MPEG-2 removes camera raw data. Moving to MPEG-2 adds streaming delivery.
What should I review after converting NEF to MPEG-2?
Check the exported file for Compression efficiency is roughly half that of H.264 at equivalent quality.; Higher bitrate requirements make it impractical for modern bandwidth-constrained delivery.; Patent licensing historically required MPEG LA pool payments, though most patents have now expired..
