+title: Increased limits for Media Transformations
+description: >
+  Media Transformations now supports inputs up to 100MB and output videos as long as 1 minute.
+date: 2025-06-10T12:00:00Z

+
+We have increased the limits for [Media Transformations](/stream/transform-videos/):
+
+- Input file size limit is now 100MB (was 40MB)
+- Output video duration limit is now 1 minute (was 30 seconds)
+
+Additionally, we have improved caching of the input asset, resulting in fewer
+requests to origin storage even when transformation options may differ.
+
+For more information, learn about [Transforming Videos](/stream/transform-videos/).
