AI video editing cost: what a generation credit plan does not cover
Most buyers price AI video on the sticker cost of a credit plan, but generation is only one line in the budget. Credits pay to create clips; editing, sound, review time, storage, and clean delivery sit on separate meters or behind higher tiers. This guide gives you a total production-cost checklist so you can compare tools on what a finished video costs, not just what one generation costs.
What a credit actually pays for
Read any provider's pricing page and you will see credits framed around creation. Synthesia now describes credits as the shared currency across all of its AI usage-based features, one common pool for everything you create. Runway is explicit that credits are the unit you spend to generate images, video, and audio, whether that is the Standard plan's 625 credits per month or the Max plan's 9,500. A credit, in other words, is a generation currency. It says nothing about whether you can trim the clip, add captions, mix audio, store the project, or export it without a watermark. Treat the credit line as your raw-footage cost and budget every downstream step separately.
The editing and enhancement layer
The edit is where a raw generation becomes usable, and much of that toolkit is priced apart from creation. CapCut is a clear example: its own comparison page describes free-tier users as having limited access to premium templates, advanced effects, fonts, and music tracks, while an advanced AI tool set that includes motion tracking and an auto caption generator is exclusive to Pro. None of those touch a generation credit; they are gated by subscription instead. So separate the question of whether you can generate a clip from whether you can finish it. A plan with generous credits but paywalled captions and cleanup tools may cost more in practice than one with fewer credits and the editing tools included. Map the edits your format needs, then check which tier unlocks each one.
Sound, captions, and dubbing
Audio and text overlays are easy to forget until delivery, and they can be billed several different ways. Because Synthesia pools credits across its AI usage-based features, added AI work such as dubbing draws on the same allowance as creation, so multilingual versions consume your generation budget rather than a separate one. CapCut, by contrast, gates its auto caption generator behind the Pro subscription and limits the free tier to its free music library, so subtitles and a wider music selection are a plan cost, not a per-clip one. Captions, voiceover, dubbing, and music can each be charged from credits, from a plan tier, or from metered top-ups. Decide how many language versions and captioned cuts you need, then confirm which meter each one draws from before you commit.
Review, retries, and expiring credits
Review is the cost buyers underestimate most, because every rejected generation is already-spent budget. Build a buffer into the credit line: if a meaningful share of attempts miss the brief, the credits behind each finished clip are the credits of every attempt it took, so size your plan against attempts, not deliverables. Timing compounds this. On Runway's Standard and Pro plans, monthly credits do not roll over and reset within 24 hours of your billing date; the Max plan rolls over up to one month of unused credits, and separately purchased credits never expire. Unused headroom on most subscription tiers is therefore lost each cycle, so oversizing a plan for rare spikes wastes credits you cannot recover. Match the plan to your steady monthly attempt volume and cover spikes with one-time credit purchases.
Storage and sync as a line item
Finished projects have to live somewhere, and cloud storage has quietly become its own cost. CapCut is the cautionary case: the 1 GB of free cloud storage it once offered was discontinued as of August 2024, while Pro provides roughly 1,024 GB. If your team relies on cross-device sync or keeps source projects in the cloud, that capability now sits inside the paid tier, separate from any editing or generation feature. Descript shows a related pattern with two independent meters: media minutes for the footage it imports, records, and processes, alongside AI credits for generative features, so running out of either blocks work on its own. When you size a plan, count the active projects, versions, and archived assets you will hold at once, and confirm whether storage is bundled, capped, or billed on top.
Delivery: watermarks, resolution, downloads
The last cost is getting a clean file out the door, and providers routinely gate delivery behind paid tiers. Runway lists no watermarks as a feature of Standard and above, while the free plan makes no watermark-free claim. Synthesia's Basic plan caps output at 10 minutes of video per month, allows no video downloads, and requires the Synthesia logo to stay; only Starter, at 29 dollars per month billed monthly, and higher tiers can remove it. Descript ties resolution to tier: its free plan exports at 720p without the watermark-free option, Hobbyist exports 1080p watermark-free, and Creator and Business export 4K. Resolution is not always the gate: CapCut states both free and Pro tiers can save video in 8K. Confirm watermark, resolution, and download rights on the exact plan you intend to buy.
