Users report HeyGen holds videos in 'pending status' until users upgrade and pay more. This forces unexpected upsells mid-project. The platform appears designed to trap users into higher tiers after they've started work.

An agency reported 'inconsistent results and product changes that affect the quality we promise our clients, which makes the platform hard to use at scale.' The platform is described as 'a slow, frustrating, glitch-ridden nightmare — completely unsuitable for anyone creating real business content.'

The platform is described as full of bugs. Updates aren't tested before deployment and wind up breaking things. The UI is hard to use with elements laid out counterintuitively. Very unstable software with screencams not included well in videos.

Over the past year, approximately 49 outages have been tracked affecting HeyGen users, averaging 2.3 per month. Incidents typically resolve within 86 minutes, but the frequency disrupts production workflows for businesses relying on the platform.

Users who subscribed to 'unlimited' translation plans had their minutes reduced overnight to 120 minutes/month without communication or explanation. Support claimed 'they had to change it' with no willingness to find solutions. This mid-subscription change affects users who planned based on unlimited promises.

HeyGen switched to a credit-based system (200 credits/minutes per month) without prior notice. One user who subscribed expecting unlimited usage exhausted credits after generating 7 short videos (less than 17 minutes total) within 18 hours. The credit burn rate is far higher than expected.

Users report supposed $30/month plans being billed as $119/month with no warning. HeyGen is described as 'rife with hidden fees.' Unexpected pricing changes mid-subscription and confusing 'unlimited' terminology are common complaints across review platforms.

Users who subscribed to Creator plan for 'unlimited video generation' discover Avatar IV (the best avatars) is limited to just 5 minutes per month. This limit is buried several pages down the pricing page. The most advertised feature isn't actually unlimited.

Analysis of 100 Trustpilot reviews shows 80% negative, with 75% citing support failures. AI chatbots loop endlessly, scripted replies ignore problems, zero escalation paths exist, and tickets remain unresolved for months. Support agents copy-paste generic responses without understanding issues.

Videos are constantly rejected for false reasons even when consisting of just one word. When users contact support, only bots respond within their chat. Users reach out multiple times for refunds with no response, having to involve attorneys.

The platform gives no real way to change payment method or properly cancel subscription. Users experience charges even when trying to remove their payment method. Account billing management is deliberately difficult.

Processing time on 30 videos is instantaneous, then it suddenly moves to 5-6 hours, which users describe as 'completely unusable.' This inconsistency makes production planning impossible. No explanation for why processing times vary so dramatically.

The platform locks your video file after submitting for animation. If there's an error that needs to be fixed, you're unable to modify it. This creates significant rework when even minor changes are needed post-submission.

A notable limitation is the inability to control the gestures of avatars in videos, restricting creative freedom. Users with Hacker News note: 'you are constrained to the hand motions and environment of the on-boarding video.' The preset animations limit customization.

Users wish the audio had more control over inflection. There's no discovered way to control the tone of audio generation. This limits the emotional range of generated content and makes all videos sound similarly flat.
