Runway Gen-3: Text & Image to Video Online
Bottom line
Runway Gen-3: text or image to video, 5 or 10 seconds, 720p from 10 credits or 1080p from 20 credits. Start from a prompt or a still image in the Text to Video tool; VdoBloom shows the exact credit cost before each Runway Gen-3 run, with no separate Runway account.
Runway Gen-3 is the older of VdoBloom's three Runway models, and the only one that supports both text-to-video and image-to-video from the same picker along with a real quality choice: 720p or 1080p. Duration is 5 or 10 seconds, and aspect ratio can be set to 16:9, 4:3, 1:1, 3:4, or 9:16 — more ratio options than either of the newer Runway models on VdoBloom.
Pricing is flat by duration and quality: a 5-second 720p clip is 10 credits, a 5-second 1080p clip is 20 credits, a 10-second 720p clip is 20 credits, and a 10-second 1080p clip is 30 credits. That makes Gen-3 the cheapest Runway option on VdoBloom at every tier, well under Gen-4 Turbo and Gen-4.5.
Prompts for any Runway model are capped at 1,800 characters on VdoBloom, shorter than the 2,500-character Kling limit or the 5,000-character default — worth knowing if you're used to writing longer, more descriptive prompts for other models.
What it costs on VdoBloom
Runway Gen-3 is priced flat by duration and quality: 10 credits (5s/720p), 20 credits (5s/1080p or 10s/720p), 30 credits (10s/1080p). It's the cheapest Runway model on VdoBloom, and the only one where the 10 free signup credits cover a full generation outright.
Runway Gen-3 vs Gen-4 Turbo vs Gen-4.5
Gen-3 is the budget, most flexible option: text or image start, real 720p/1080p choice, five aspect ratios, and the lowest prices (10–30 credits). Gen-4 Turbo is image-to-video only, fixed at 1280×720 output, and priced 20–40 credits by duration (5s/8s/10s). Gen-4.5 supports both text and image starts like Gen-3, is also fixed at 1280×720, and costs the most: 48–96 credits.
Gen-3 suits anyone prioritizing price or needing 1080p or an uncommon aspect ratio. Gen-4 Turbo and Gen-4.5 are newer models at a fixed 720p, priced higher, for image-to-video (Gen-4 Turbo) or either mode (Gen-4.5).
