Runway Clips Made in AutoFeed
What Runway Is Good At
Runway is the New York company behind the Gen series of video models, used widely in film and advertising work. Gen-4.5 is its current flagship, known for motion quality and for following the prompt closely.
On AutoFeed, Gen-4.5 takes a text prompt or a starting image and renders 5 or 10 second clips at 720p in vertical, horizontal or square format. The clips have no generated sound.
AutoFeed runs Gen-4.5 through Replicate, so you pay per clip in credits instead of buying a separate Runway plan.
Use it for
- Hero shots where motion quality matters most
- Prompts with specific staging that weaker models ignore
- Animating a product shot or key frame you already have

Prompt Tips for Runway
- Describe the camera and the subject separately ("handheld close-up; a chef flips a pancake").
- Use a starting image to lock the look, and the prompt only for motion.
- Ten seconds suits a slow reveal; keep fast action to 5 second clips.

Runway on AutoFeed: FAQ
Do I need a Runway account?
No. AutoFeed runs Gen-4.5 through Replicate, so there is no separate Runway subscription.
Do Runway clips on AutoFeed have sound?
No. Gen-4.5 generates video only. For a clip with generated sound, use Veo 3.1, Kling 2.6, Seedance 2.0, Vidu or Grok Imagine.
How many credits does a Runway clip cost on AutoFeed?
From 2,400 credits (a 5 second Runway Gen-4.5 clip at 720p) to 4,800 credits (a 10 second Runway Gen-4.5 clip at 720p). The table on this page lists every combination of variant, resolution and length.
How many Runway clips do I get on each plan?
Hobby ($19/month, 15,000 credits): 3 to 6 clips; Pro ($59/month, 60,000 credits): 12 to 25 clips; Ultimate ($249/month, 180,000 credits): 37 to 75 clips. Credits are shared across everything you make on AutoFeed, so clips on other models or faceless videos draw on the same balance.
Can I try Runway for free?
The cheapest Runway clip costs 2,400 credits, more than the 1,000 free credits a new account receives, so Runway needs a plan. The free credits do cover a clip on a cheaper model such as Wan 2.2.
Does Runway on AutoFeed add a watermark?
No. AutoFeed adds no watermark or logo. Each clip is delivered as an MP4 at 1080x1920 for 9:16, 1920x1080 for 16:9 or 1280x1280 for 1:1, ready to download or post.
Is Runway text to video or image to video?
Both. Runway on AutoFeed accepts a text prompt on its own, or a starting image plus a prompt describing the motion.
Can AutoFeed post Runway videos to TikTok and YouTube?
Yes, one clip at a time. When a clip is ready you can post it to a connected TikTok or YouTube account straight away, or pick a date and time to schedule it. AI video clips are not a recurring series: the series that write, render and post new videos on their own schedule are the faceless formats (AI slideshows, Reddit stories, Would You Rather, Pick One and Fake Text).
