Can somebody help me with being able to sync audio and GIFs? The audio is sixty seconds and the GIFs are normally sixty seconds long also (300 frames).

I'll move this over to the Questions about Scratch section for you - that's a better fit for this kind of topic

scratch works at 30 fps so that would be 10 secs of gifs.
maybe add a wait 0.5 or smth to sync

i have that same problem
