If you opened your Sora 2 app sometime last month and saw nothing but a shutdown notice, you are not alone. OpenAI closed the Sora 2 consumer app on April 26, 2026, ending a year of casual access to one of the most-talked-about AI video tools on the market. The API stays open to developers until September 24, but for everyone using Sora 2 through the app for client work, internal videos, or content experiments, the migration is already overdue.
The good news is that the field caught up faster than anyone expected. Veo 3.1 from Google and Runway Gen-4.5 are now both genuinely better than Sora 2 was at most practitioner tasks, and they cost less. Here is what to switch to, when each one wins, and the exact migration plan to follow this week.
Why Sora 2 Was Shut Down and What That Means for You
OpenAI announced the Sora 2 consumer shutdown on March 24, 2026, and pulled the app on April 26. The reason given was a focus shift to the API and to integration inside ChatGPT itself, but the practical effect is the same. Anyone who built a workflow around the Sora 2 app needs to move. Your saved generations remain downloadable through the end of June 2026, after which they will be deleted.
If you only used Sora 2 occasionally, the urgency is low. If you used it weekly for client deliverables, social content, or product mockups, you are losing a load-bearing tool. The replacement choice matters because output quality, pricing model, and creative control vary significantly across the alternatives.
The Two Tools That Replaced Sora 2 for Most Practitioners
Two tools absorbed almost all of the Sora 2 user base. Veo 3.1 from Google and Runway Gen-4.5. They are not the same tool. Picking the right one depends on what kind of video you make.
Veo 3.1, accessible through Google's Vertex AI and through Gemini Advanced, leads on prompt adherence and native audio. It produces clips with synced sound, dialogue, and ambient audio in one pass, which Sora 2 could not do reliably. It also outputs at native 4K in both landscape and portrait, which matters for vertical social video. Pricing starts at about 0.15 US dollars per second in fast mode through the Gemini API.
Runway Gen-4.5 leads on creative control. The Motion Brush, camera move controls, and reference-driven character consistency are still ahead of anything Google ships. Runway's "World Engine" architecture in Gen-4.5 also produces more believable physics, gravity, and momentum than Sora 2 ever did. The Runway Standard plan is 12 US dollars a month annual, and it bundles Gen-4.5 with Veo 3.1 and Kling 3.0 access, which makes it the best value option for most creators who want to test multiple models in one workflow.
When to Pick Veo 3.1 vs Runway Gen-4.5
The choice between these two is rarely about quality. Both produce frontier-tier output. The choice is about what kind of video work you do most often. Here is a practical decision framework.
Pick Veo 3.1 if you produce social-first content where the dialogue or ambient audio is part of the shot. Native sync audio in one generation collapses a step that used to require ElevenLabs plus a manual mix. Also pick Veo 3.1 if you generate establishing shots, narrative scenes, or anything where you describe what should be in the frame and want the model to follow that description tightly. Prompt adherence is where Veo wins.
Pick Runway Gen-4.5 if you work on commercial or marketing video where character consistency across clips matters. The reference-driven approach means you can lock a character or product across a 6-clip sequence, which is the workflow most agencies care about. Also pick Runway if you direct the camera. The Motion Brush and explicit camera moves give you the kind of control that text-only models do not.
If you cannot decide, take the Runway Standard plan first. The bundled access to Veo 3.1 and Kling 3.0 lets you run the same prompt across three models on the same day and pick the winner. After a month you will know which engine matches your taste.
How to Migrate Your Sora 2 Workflow This Week
A migration is not just "use a different tool." Most practitioners have small habits and prompt patterns built up around Sora 2 specifically. Here is the migration sequence that minimises rework.
First, export everything from Sora 2 before June 2026. Open the app, download every saved generation you might want to reference, including the prompts used. This is your library and your training set for how you actually write video prompts.
Second, pick your primary tool and create the account. If you went with Runway Standard, set up a single project for replacement testing. If you went with Veo 3.1 through Gemini Advanced, create a project folder for video work and bookmark the model.
Third, recreate three of your most-used Sora 2 prompts in the new tool. Do not improvise. Use the exact text of your previous prompts and see what comes out. The output will be different, sometimes much better, sometimes weaker on a specific dimension. This is how you calibrate the new tool against your own taste.
Fourth, build a small prompt library in a Notion or Google Doc. Capture the prompt, the model, the output URL, and a one-line note on what worked. Six entries is enough to start. The fastest practitioners do not have better tools. They have better notes on what their tools do well.
A Prompt Template That Works on Veo 3.1 and Runway Gen-4.5
Here is a prompt template that translates well across both replacement models. Use it as a starting point and adapt the bracketed sections.
Subject: [one person or object the camera focuses on, with two specific visual details]
Action: [what they are doing, in present tense, kept to one verb and one object]
Environment: [the setting in 4 to 6 words, with one specific atmospheric cue]
Camera: [specify shot type, lens feel, and movement, for example "slow dolly forward, 35mm cinematic, slight handheld feel"]
Lighting: [one named lighting style, for example "golden hour low sun" or "soft overcast diffused"]
Audio: [for Veo 3.1 only, describe ambient audio and any spoken line in quotes]
Style: [one or two named reference styles, for example "Wong Kar-wai colour palette" or "anamorphic documentary"]
This structure works because both models respond best to specific, named direction rather than vague mood words. The fastest improvement most practitioners see is dropping words like "beautiful" or "stunning" and replacing them with specific shot, lens, and lighting language. The same shift that moved Midjourney users from beginner to power user applies here.
What Sora 2 Did Better That You Will Miss
Honesty about what you are losing helps the migration. Sora 2 had two strengths that the replacements have not fully matched.
The first was the photoreal cinematic clip with rich prompts. When given a long descriptive prompt, Sora 2 Pro produced output that looked like a real film camera capture. Runway Gen-4.5 is now competitive on this dimension but only with the World Engine settings tuned correctly. Veo 3.1 is slightly more stylised. If your work depended on the Sora 2 photoreal look, accept that you will need a few weeks of recalibration.
The second was the social-app feel. Sora 2 inside its dedicated app was a fast, casual, mobile-first experience that made experimentation feel cheap. Runway and Veo are both more professional, more deliberate, and more expensive per generation. The casual play loop is gone. Most practitioners will not miss this. Some will, and Kling 3.0 inside the Runway bundle is the closest replacement for that fast-iteration feel.
The Bottom Line
Sora 2 closing was a market jolt, but the alternatives have already caught up. For most Hong Kong practitioners, the right move this week is Runway Standard for 12 US dollars a month, which gets you Gen-4.5, Veo 3.1, and Kling 3.0 in one place. If your work is mostly narrative or social with sound, lean on Veo 3.1. If your work is commercial or needs character consistency, lean on Gen-4.5. The tools are mature enough that the bottleneck is no longer the model. It is the prompt and the taste.
We understand AI. We understand you better. With UD by your side, AI doesn't feel cold. If your team is mid-migration and needs the workflow rebuilt around the new stack, that is the kind of hands-on work UD has been doing across Hong Kong SMEs for 28 years.
Now that you have the migration path, the next step is rebuilding the actual production workflow inside the new tools so it runs reliably for every brief. We'll walk you through every step, from model selection to prompt libraries and review checkpoints.
