Documented facts
The following fields come from the official provider source, reviewed on the date above.
- Identity and availability
- HeyGen Video; official launch catalog route names 1.0. September 30 help page says API access is available and web access is forthcoming. Exact API model identifier is not verified here.
- Modes and audio
- Text-to-video, image-to-video and reference-to-video. The text-to-video description includes synchronized dialogue, ambience and effects.
- Text/image rates, USD per output second
- October promotion: 480p $0.01; 768p $0.015. Published November-onward standard rates: $0.02 and $0.03 respectively.
- Reference-video rates, USD per billable second
- October promotion: 480p $0.02; 768p $0.03. Published standard rates: $0.04 and $0.06 respectively.
- Reference billing basis
- Input video seconds plus output seconds. Image and audio references add no charge according to the help page.
- Availability qualification
- Documentation was checked, not inference. Exact promotion cutoff timezone and account-specific eligibility remain unverified.
Cost the reference as well as the result
Arithmetic example: a five-second output at 768p costs $0.075 at the published text/image promotional rate. With a five-second video reference, ten billable seconds at the reference rate cost $0.30. These examples assume one successful request, no additional services and the documented promotion applying. They are estimates from the table, not invoices or measured generation runs. HeyGen mode-specific pricing table.
The practical decision
Choose the input mode before making a cost comparison. An image can establish an opening composition; a video reference adds a separate temporal input to evaluate. Preserve the original files and record which controls were actually sent. If the reference is essential to the task, comparing only an output-second price hides part of the requested work. Estimate accepted-shot cost after allowing for unsuccessful attempts, then compare the same mode, resolution and delivery requirements across providers.
What to record in your own comparison
- Inspect continuity across the whole shot: subject identity, object boundaries, camera movement and the completion of the requested action. A strong opening frame does not establish consistency later.
- Review native audio separately from picture. Check dialogue, timing and unwanted sounds against the intended use; an attractive image cannot establish acceptable sound.
- Record reference duration and output duration separately, alongside resolution and the dated rate. Keep the reference file with the result so someone else can reconstruct the comparison.
- Evaluate matched tasks with retained outputs. Use the same acceptance criteria and distinguish provider demonstrations from your own results; do not turn one selected clip into a general quality ranking.
Limitations and unknowns
No hands-on results, independent ranking or measured speed. Maximum duration, aspect ratios, seeds and detailed control schema were not established by this review. Downloadable weights and their license remain unknown. Published future rates are provider statements, not a guarantee of what a later invoice will charge.
