Loading Images/Rolls

Load in images by selecting a few individual images, or an entire directory's worth at once. Filmvert operates per-roll, so directories will import as rolls. Individual images will need to be added to a roll.

Analysis

Set the four corners of the analysis region to encompass the image. Exclude any sprocket holes or any scanning equipment as this will throw off the inversion. The analysis only looks at pixels within the set region, so portions of the frame can be included/excluded to influence the analysis.

Set the base color by holding Cmd + Shift, and clicking and dragging a clear space in the image where the film base is visible.

Click "Analyze"

The engine will process the image, setting the white point and black point based on the lightest and darkest areas of the image. These points will be displayed on screen.

The "Analysis Bias" slider can be adjusted, and the image re-analyzed to tweak the results of the analysis.

Image Adjustments

Depending upon the results of the analysis, the Analyzed White Point and Analyzed Black Point can be adjusted to taste.

Further, the Grade options can be used to set a quick grade on an image.
