Claude Fable 5.2 vs Opus 5.5 Make a 3D Animated Video From Scratch — Transcript

Full transcript

1. 0:00Yesterday, I compared Claude Fable 5.2
2. 0:03and Opus 5.5, and most of you liked the
3. 0:06Opus film more. But that test was
4. 0:08simple. One short story all in 2D. So
5. 0:11this time I pushed them as far as they
6. 0:14go with 2D and 3D. Real physics and five
7. 0:18impossible worlds. They got the same
8. 0:20voice over and the same prompt. Watch
9. 0:22both and pick left or right. You're
10. 0:25falling up past cars and buses floating
11. 0:28into the clouds toward a black hole
12. 0:30that's tearing the sky open. Around you,
13. 0:34every world is coming apart. Half of it
14. 0:36flat, half of it deep, both at the same
15. 0:39time. Click. Everything rewinds. 5
16. 0:42minutes ago, you found this remote in a
17. 0:44drawer. You press one. 2D becomes 3D.
18. 0:48You run up the stairs, shove the door
19. 0:50open at the top, and stumble into the
20. 0:52basement. You turn around and sprint up
21. 0:54again faster and burst through the same
22. 0:57door into the same basement. There's one
23. 1:00other door down here. You open it and
24. 1:02you're looking into your bedroom at your
25. 1:04own back. You step in. You look out of
26. 1:07the window. The street is below you. You
27. 1:10lean left and it's above you. You lean
28. 1:12right and you're looking at it from the
29. 1:14side. You open the wardrobe. Inside
30. 1:17there's a hallway. You walk all the way
31. 1:20to the end of it, open the door, and
32. 1:22step into your own room. You press two.
33. 1:25You're standing in a street. 3D folds
34. 1:28back into 2D, sideways. This time, you
35. 1:31can only go left or right. And every 3
36. 1:33seconds, the world redraws itself in a
37. 1:36completely different style. Then the
38. 1:38storm hits. Water floods in from the
39. 1:41left, lifts the cars off the ground, and
40. 1:43chases you up a ladder, onto a roof,
41. 1:46onto a chimney. A tornado comes down out
42. 1:49of the clouds and pulls in the fences,
43. 1:51the roof tiles, even the flood water.
44. 1:54Lightning splits the tree next to the
45. 1:56house. You hold on to the chimney, your
46. 1:58feet off the ground. You barely reach
47. 2:00the remote and press three. You're
48. 2:02standing in a city center. 2D becomes 3D
49. 2:05again, and gravity has turned upside
50. 2:08down. A car comes at you at full speed,
51. 2:11lifts off the road, and misses you by an
52. 2:13inch. Everything starts floating. You
53. 2:16grab a street lamp and the remote slips
54. 2:18out of your hand. You catch it just
55. 2:20before it's gone and you press four. The
56. 2:23world still looks 3D. The street runs to
57. 2:26the horizon. You throw a stone down it.
58. 2:28The stone hits the horizon with a flat
59. 2:30tap and slides down the sky. You step
60. 2:33sideways and the whole street slides
61. 2:36along with you. And here, time runs
62. 2:38backwards. A shattered shop window
63. 2:41gathers itself up from the pavement. A
64. 2:43building lying across the road stands
65. 2:45back up floor by floor. At the end of
66. 2:47the street where your stone hit, a black
67. 2:50hole gives back everything it ever
68. 2:52swallowed. Behind you, your footprints
69. 2:54walk back to your feet. You press five.
70. 2:56Back to 3D. You're back in your room.
71. 2:59And on the TV is this room. You, the
72. 3:02remote, and the TV. On that screen, the
73. 3:05same again. Smaller and again. Every
74. 3:08second screen is 2D. You lean in too
75. 3:11close and you fall through a 2D room,
76. 3:14through a 3D room, faster and faster.
77. 3:17And every room is a little older than
78. 3:19the last. In one of them, another you
79. 3:21looks up and watches you fall past. The
80. 3:24last screen is a single pixel. You fall
81. 3:26into it anyway. You hold down the power
82. 3:29switch. Every world rewinds in 3
83. 3:32seconds, and you're home, flat, 2D, just
84. 3:35like before. The staircase goes up and
85. 3:38stays up almost. Your shadow is still
86. 3:413D.
87. 3:42So, which one did you pick? The film on
88. 3:45the left was made by Fable 5.2 and the
89. 3:48one on the right by Opus 5.5. Opus
90. 3:51finished its film in about an hour and
91. 3:53Fable took 85 minutes. At API prices,
92. 3:56Opus cost about $16 and Fable about 27.
93. 4:00Both of them got a single prompt. Make
94. 4:02the whole film in code, including the
95. 4:04sound and the music with no text on
96. 4:07screen in one continuous take and render
97. 4:10it yourself. I didn't fix a single
98. 4:12frame. So, what you just saw is their
99. 4:15first try. And this was harder than it
100. 4:17looks. Each model only got the voice
101. 4:19over and the timing of every word with
102. 4:21no images, no reference, and no style.
103. 4:24The story never says what anything looks
104. 4:27like. So, everything on the screen had
105. 4:29to come from the words alone. The story
106. 4:31only says when the world is 2D and when
107. 4:34it's 3D. And they worked out everything
108. 4:36else from the context. The real goal was
109. 4:39to test their reasoning, not just their
110. 4:41drawing. The story says what happens,
111. 4:43but never how to show it. How do you
112. 4:46show a staircase that leads back into
113. 4:48the basement? Or a world that looks 3D
114. 4:50but isn't, or a screen inside a screen.
115. 4:53Each of those is a puzzle they had to
116. 4:55solve on their own and then build in
117. 4:57code while switching between 2D and 3D.
118. 5:00exactly on the click. And here's the
119. 5:02part I didn't expect. Neither of them
120. 5:05used a 3D library. Both wrote their own
121. 5:073D engine from scratch. Opus built one
122. 5:10with shadows, portals, and a screen that
123. 5:12can show another scene inside it. Fable
124. 5:15built a renderer that can draw every
125. 5:17pixel, either in 3D or flat, in 10
126. 5:20different 2D styles. And that's how it
127. 5:22moves between the two. So nothing in
128. 5:24these films is borrowed. Everything you
129. 5:26see is something the model wrote itself.
130. 5:29And that's exactly where the difference
131. 5:30shows. Opus flickers a lot while Fable
132. 5:33layers its objects into each other and
133. 5:35its lighting and its character look far
134. 5:38more real. They also think about the
135. 5:40camera in different ways. Fable builds a
136. 5:42whole world around you and uses it,
137. 5:44showing more of the environment in every
138. 5:46scene. Opus is more about the
139. 5:48experience. It puts you inside the
140. 5:50moment, and some scenes are shot from
141. 5:52your own eyes. You can see it right from
142. 5:54the opening. Fable rips the sky open
143. 5:56like paper with cars, toys, and debris
144. 6:00pouring through the clouds, while Opus
145. 6:02drops you over a whole city toward a
146. 6:04black hole with a burning disc. When the
147. 6:06first button turns the world from 2D
148. 6:09into 3D, both of them build a real 3D
149. 6:12house out of the flat room. They even
150. 6:14had the same idea for the staircase
151. 6:15loop. Both cut the house open so you can
152. 6:18watch yourself run up the stairs and
153. 6:20come out in the basement. With the
154. 6:22second button, the world has to change
155. 6:24its style every 3 seconds. Fable goes
156. 6:27from a flat illustration to a blueprint,
157. 6:30a pencil sketch, a mosaic, and
158. 6:32watercolor. And Opus goes through
159. 6:34halftone, cut paper, neon lines, and
160. 6:37green pixels while the flood keeps
161. 6:39chasing you through every one of them.
162. 6:42When gravity flips with the third
163. 6:43button, Fable throws a car straight at
164. 6:45the camera, and Opus turns the whole
165. 6:47city upside down and leaves you hanging
166. 6:49from a street lamp. The fourth button
167. 6:51was the hardest one because the world
168. 6:53has to look 3D, then give itself away as
169. 6:56flat, and then runtime backwards. With
170. 6:59the fifth button, both of them go
171. 7:01through a screen inside a screen all the
172. 7:04way down to a single pixel. Opus ages
173. 7:06each room into black and white, and
174. 7:08Fable drains the color out of each one
175. 7:10until it's almost gone. And for the last
176. 7:13line, where your shadow is still 3D,
177. 7:15Opus gives you a shadow on the wall that
178. 7:18moves on its own, and Fable turns you
179. 7:20into a dark 3D shadow standing in a flat
180. 7:23house. Of course, writing your own 3D
181. 7:25engine in an hour has a price. Opus
182. 7:28flickers all over the film on thin lines
183. 7:30and shadows, the kind of thing a mature
184. 7:32library solved years ago. Fable
185. 7:34flickers, too, but far less. I left all
186. 7:37of it in because this is exactly what
187. 7:39they made. So, here's my verdict. Fable
188. 7:425.2 is clearly the better animator, but
189. 7:45it costs about twice as much to do the
190. 7:47same job. If you want the best result,
191. 7:49use Fable. If you're making a lot of
192. 7:51videos, Opus still gets you most of the
193. 7:53way for half the price.
