After Effects' Radial Blur keeps a layer's edges: Zoom 20 on a flat grey 960x540
solid over red (case 713) stays flat and opaque to its edge, and a zoomed
full-frame ramp (case 829) keeps the frame opaque (2/255 at x = 2, 253/255 at
x = 1917 on row 540). EffectCraft sampled transparency outside the layer, so its
edges faded and the red below showed through (713: 3.9 % of the frame off, max
64/255). Now 713 is identical to AE (max 0/255), CPU and GPU. CC Radial Blur
(already matching AE) is unchanged.

With Glow Colors = Original Colors, After Effects thresholds each channel of
the straight colour separately and the glow is 8 x (value - threshold +
0.061) per channel (times Intensity), nothing below: fitted to AE 2026
renders of grey 0.65 / 0.8 / 0.9 / 1, orange (1, 0.5, 0) and (0.2, 0.6, 1)
solids at Threshold 40 / 60 / 80 % and Radius 10 / 30 (36 channel values,
exact to the 8-bit capture; an orange solid glows red only). EffectCraft
scaled the colour by a luminance threshold (k = (L - thr) / (1 - thr)), about
3.7 x too dim on white. Cases 806 / 810 / 811 (32 bpc): outside the layer
now within 3/255 of AE (806 white at Intensity 1: 119 = AE, was 32); grid
0 points off for 806-810. The glow's alpha (the blurred layer alpha) and the
Arbitrary Map / A & B colours and alpha-based glows are unchanged.
Stacked on fix-glow-halo (same lines). Not changed: Composite Original's
semantics are swapped against AE's names (EffectCraft's "On Top" adds the
glow over the original, which AE calls "Behind"; AE's "On Top" keeps the
original over the glow), so imported AE Glows at the default Behind show
no glow inside the layer (811 interior 204 vs AE 255).

With Glow Based On Color Channels, After Effects gives the glow the layer's whole
alpha (blurred), not the thresholded part, and Intensity scales only its colour:
a layer below the threshold darkens what lies under its edge. Fitted to AE 2026
renders of a grey solid over red (cases 524, 807-809): the halo is the same at
Intensity 1 and 3 and with Composite Original Behind or On Top, and its edge is
an erfc step of sigma = 0.384 x Glow Radius at radius 10 and 30 (was radius / 2).
524 (Glow defaults on a 50 % grey solid): EffectCraft had no halo (max 116/255
off at the edge); now red 248/234/208/165/140 at 7.5/5.5/3.5/1.5/0.5 px outside
vs AE 249/235/206/164/140, max 2/255 over the frame, CPU and GPU. The blur
width applies to every glow; alpha-based glows keep their coverage rule
(thresholded alpha, scaled by Intensity). Not matched yet: the brightness of glows above the
threshold (AE about 3.7 x brighter for a white solid, cases 806, 810, 811).

- render --progress with a piped stderr writes well-formed
`progress <done> <total> <elapsed> <left|->` lines, one per change, and
the same render without the flag writes none.
- A template's Media Replacement control takes {"path"|"file"|"media": …},
is found by name ignoring case, and a path that cannot be imported fails
with an error naming the control and the path.
