Thank you for your fast reply !
My Macbook
Macbook pro retina 2013 : 2,4 GHz Intel Core i5
Memory : 4 Go 1600 MHz DDR3
Graphics : Intel Iris 1536 Mo
I’m using After Effects CC2014, so I’m creating a playlist channel with a lot of music on a simple background & my logo popping according to the music (shakes with the kicks, etc)
I’m using for this, 2 effects : SoundKeys and Twitch, I automate the twitch so it’s “attached” to Soundkeys, itself “attached” to the music. Nothing else ! I don’t know if these effects use so much memory…
I use a total of 4 compositions (Song, Visual, Soundkeys and Final)
1) the “Song” composition is placed in the Visual composition
2) The “Song” and “Visual” compositions are in “Soundkeys” composition
3) “Soundkeys” composition in “Final” composition
Then I use the “Final” composition to start the rendering, and after 20sec (when the first kick of the song comes with the twitch effect), it instantly crashes, it’s highly frustrative because it’s my very last step !!
I actually use a mp3 ! Good to hear, I’ll do it with wav. compressed music
I’m waiting for your reply, thanks again I really appreciate it
