Video Issues

Symptom: Cutscenes or video segments show a black screen instead of playing.

Cause: Some games use platform-detection logic to choose between different video formats for mobile and PC. Depending on which platform archive you imported (e.g., PC vs Android), the video assets the game’s code is trying to load may not be included in the archive.

Solutions:

1. Try a different platform archive — If you imported the PC version, try the Android version (or vice versa). The other archive may include the video assets the game expects on mobile.
2. Contact support — If no available archive resolves the issue, reach out on Discord for a game-specific patch.

Symptom: Frame rate drops, lag, or the device heats up during cutscenes or animated sequences.

Cause: The game uses high-quality WebM video files. iOS does not provide hardware decoding for the WebM format, so Spark must decode these videos entirely in software. This is significantly more CPU-intensive than hardware-decoded formats and can cause performance issues, especially on older devices or during long or high-resolution video sequences.
