Rendering Time with Audio Visualizer

Report · Jul 04, 2018

Trying to make a video with an audio waveform visualizer such as this:

Has worked great, except the rendering time is unbelievably long. It takes about 2 hours for 1 minute of video. I want to try to do this for about 1 hour long audio clip. Any suggestions?

Laptop i7 processor 1.9Ghz (2.4Ghz), 8GB RAM, Win10x64, Nvidia Gforce GT630M, 512GB solid state HDD.

I've tried rendering with Quicktime and H_264.

I'm actually not even sure my video card is being utilized in the processing, can't find much online about how to be sure the hardware is set up properly.

- I tried turning off render preview (pushed caps lock before render queue) but it didn't help much

- I tried holding shift and going to preferences, went down to secret menu, and disabled layer cache and ignore sequence rendering errors. still no difference.

- I tried different video format outputs (quicktime h264, AVI PAL and NTSC, etc.) and it seems to make no difference.

- i turned on classic 3D instead of ray-traced 3D

- I even tried putting the quality down to like 10% and it STILL takes forever! It feels like I'm doing something wrong...

thanks!

That's the price you pay in AE -- long render times. Get used to them.

There's nothing wrong. The tutorial involves sampling audio with delay, expressions and soem other stuff, all of which can require AE to sample and process a ton of source frames just to produce a visible frame. As far as AE's internal mechanics go that's perfectly normal. You need to adapt rather than have wrong ideas about how AE works and what it is and manage your expectations based on that.
