Camera Raw creates flickering video when processing DNG sequences (RAW video from Magic Lantern). Because of the way Camera Raw works, using any of the exposure sliders can create wildly varying results from frame to frame when developing DNG sequences from Magic Lantern RAW video (5D Mark II and III), even when you synchronize settings. I realize CR dynamically sets white and black points for each frame, and when the content shifts, so does the exposure. But we would all like to render our DNGs in Camera Raw / Lightroom. I would like you to consider making it possible for us to develop sequenced DNGs in Camera Raw so we can do our beautiful RAW videos without terrible flickering.

Here's a workaround/trick while processing image sequences with the Camera Raw engine (from Eric Chan):

It depends on which controls the users use. If they use controls that depend on image content, then flickering can happen. So the trick is to limit oneself to using controls that have (mostly) static behavior in PV 2003/2010, namely:

Exposure
Brightness
Blacks
Brightness
Contrast
Vibrance
Saturation
Parametric/Point Curve
HSL / Convert to Gray (do NOT use "Auto" mode for Convert to Gray)
Split Toning
Manual Lens Corrections
Grain
Post Crop Vignette
Color Profile
Camera Calibration Sliders

In particular, avoid the following:

Fill Light
Clarity Effect
Dehaze (PV 2012 only)
'Recovery' will be borderline.
