Im using After Effects to create a sound waveform on a video, the music im using is in Wave format...
I put it all together fine, seems to be working, i add it to render Queue and once it has finished i play it, the video and soundwaves are quite laggy and the actual music stops after about 2 seconds, its really bugging me now, is there anyway of fixing this?
It sounds like you have rendered your project to a lossless or uncompressed codec. Uncompressed video will not playback in real time. Try adding your project to the Adobe Media Encoder or simply load your rendered video into AME and render to an appropriate delivery codec.
This is only a guess because I know nothing about your project except that it has playback problems. If you told us anything about your settings and your system we might be able to help with the thousands of other things that could go wrong.
What Rick said. Read this:
If the issues persist, we need a lot more info. Could of course be some audio buffer issue due to flakey drivers or configuration issues as well.
