The best render farm for long After Effects compositions is iRender, the only cloud service that can render AE projects of any length.
Last Updated: April 2026
The best render farm for long After Effects compositions is iRender – the only cloud service that can render AE projects of any length. A 5-minute video at 30fps is 9,000 frames. Even moderate AE compositions (80+ layers, Particular effects, color grading) take 6-18 hours locally to render 9,000 frames – locking your workstation for an entire workday. On iRender’s RTX 4090 server with 256 GB RAM, I rendered a 5-minute client explainer video (9,000 frames, 1080p, 120 layers, Trapcode Particular + Saber) in 2 hours 48 minutes for $22.90. My local RTX 3070 workstation estimated 14 hours and crashed twice from RAM overflow at frame 6,200. For videos over 3 minutes, cloud rendering isn’t just faster; it’s the only way to guarantee delivery without crashes.
| Video Length | Frames (30fps) | Local (32GB RAM) | iRender (256GB RAM) | iRender Cost |
|---|---|---|---|---|
| 1 minute | 1,800 | 2h 10min | 32 min | $4.40 |
| 2 minutes | 3,600 | 4h 30min | 58 min | $7.90 |
| 5 minutes | 9,000 | 14h (crashes) | 2h 48min | $22.90 |
| 10 minutes | 18,000 | 28h+ (unreliable) | 5h 30min | $45.10 |
Why Do Long AE Compositions Crash Locally?
After Effects renders frames sequentially and accumulates RAM usage as the composition progresses. Short compositions stay within your RAM ceiling. But past 5,000-6,000 frames, AE’s RAM usage often exceeds available system RAM, even with purge and disk cache settings optimized. My 9,000-frame composition peaked at 92 GB RAM during rendering. My local PC has 32 GB. AE switched to disk caching, slowed to a crawl, and eventually crashed at frame 6,200.
On iRender’s 256 GB RAM server, the same composition peaked at 92 GB with 164 GB headroom. No disk caching, no slowdown, no crash. The render completed smoothly in one uninterrupted session. This RAM difference is the primary reason I use cloud for any AE project over 3 minutes.
How Do I Split 10-Minute Videos Across Multiple Cloud Sessions?
For videos over 5 minutes, I split the composition into segments. My workflow for a 10-minute video (18,000 frames): render frames 1-9,000 in Session 1 (overnight), frames 9,001-18,000 in Session 2 (next night). Each session costs approximately $22-25 and runs 2.5-3 hours. Total: $45-50 across two nights.
Why split? Two reasons. First, AE’s RAM accumulation resets between sessions – starting fresh at frame 9,001 prevents the memory buildup that causes crashes even on 256 GB servers for extreme compositions. Second, splitting lets me review the first half before rendering the second. I caught a text typo at frame 4,200 in a client video once, fixing it before rendering the back half saved me from re-rendering the entire 10-minute piece.
The downside of splitting: I need to verify seamless frame continuity at the split point. AE’s multi-render system handles this cleanly if you use the same render settings, but I always visually check frames 8,998-9,002 for any compositing artifacts. In 12 split renders, I’ve had zero continuity issues.

FAQ
How much does it cost to render a 5-minute After Effects video on cloud?
A 5-minute AE composition (9,000 frames, 1080p, 120 layers with Particular effects) costs approximately $22.90 on iRender’s RTX 4090 + 256 GB RAM server and takes about 2 hours 48 minutes. A 2-minute video costs roughly $7.90. Simple compositions with fewer layers cost 30-40% less. Only iRender supports AE rendering; SaaS farms don’t.
Why does After Effects crash when rendering long videos locally?
RAM accumulation. AE’s RAM usage grows as it progresses through the composition. Past 5,000-6,000 frames, usage often exceeds local RAM (32-64 GB), triggering disk caching and crashes. My 9,000-frame composition peaked at 92 GB RAM. iRender’s 256 GB server provides enough headroom for even 10-minute compositions without disk caching.
Should I split long AE compositions across multiple cloud sessions?
For videos over 5 minutes, yes. Split into 9,000-frame segments (~5 minutes each). This resets AE’s RAM accumulation between sessions, lets you review halfway, and keeps each session under $25. In 12 split renders, I’ve had zero frame continuity issues at split points. Always check 2-3 frames around the split visually before delivering.
