Extremely Slow Render Time

Hello Everyone,

 

Yesterday I encountered a strange problem. When I started rendering the video I was working on, the estimated time was about 5 hours. After a while, it changed to 10, then 15 hours. Now it has been 16 hours of rendering, and there are still 11 hours of estimated time left. What is going on?

 

I'm pretty sure I used all the right settings for this, but anyway, here is the information.

 

Video:

- Total time: 2h30m

- Complexity: Its a podcast video, with music playing on the background and a couple of channels of motion graphics looping. There is also a layer or two that are reacting to the audio amplitude.

- The teaser I made for instagram: the rest of the video is the same.

My PC:

Ryzen 7 5700x

32 gb RAM 3600mhz

RTX 3060TI

2TB SSD NVME M2

 

Windows 11

After Effects 24.5.0

 

 

 

Thank you!

As much as I like to rag on AE, this is primarily user error. 

AE is supposed to fit into a traditional VFX pipeline, which means you edit in another program, then cut out the few moments that need VFX, apply them in a compositing software, then drop them back into the video editing program. AE has never been optimized for videos exceeding a minute or two, and since development nonsense inflated its RAM usage, it really can't handle all that much. In fact-

You can see here that the maximum supported windows spec tops out at about 80 seconds of 4K footage, or 5 minutes of 1080p. Any more than that, and you're treating your hard drive like RAM, which is like 1/30th to 1/300th the speed of RAM, all while thrashing its lifespan in the meantime.

 

If you need those motion graphics, prerender them to a lossless format, then place it into a premiere or davinci resolve project. Those are better able to handle long format video.

Yeah that makes a lot of sense. Thank you! I will try to change my workflow a bit.

Yeah, but i still personally believe AE should have been able to handle your case natively, though. Most stuff in RAM isn't being worked on I think, and realistically, most effects should only need to have a few frames in RAM at any given time, (just check in advance how many each effect use, take the max and load those frames, and then move to the next frame, and keep what is being used there, add what's next, then remove what's not used, which would open up AE to effects in which each frame takes a minute of footage into account, or GPU effects which take into account 150 frames at a minimum, for midrange gaming GPU's
