Penny's Verdict

Synthesia is the ultimate 'good enough' tool for business communication. If you are trying to film a heart-tugging Super Bowl commercial, hire a director. But if you're an HR lead trying to get 500 employees to watch a health and safety briefing without falling asleep, this is your best friend. It turns the process of making a video from a three-week production nightmare into a 20-minute task that feels like editing a slide deck. I use the 'PowerPoint Test' here: if the information is more important than the 'vibe,' use Synthesia. The ROI is undeniable when you consider that a single traditional video shoot can cost £3,000+, whereas here you're paying roughly £15 to £50 a month for unlimited updates. Just be careful with the custom avatars; if the lighting isn't perfect during your setup, they can end up looking a bit robotic, which distracts from your message.

Frequently Asked Questions

Can I use my own voice and face in Synthesia?+
Yes, but it's not included in the base price. You can create a 'Custom Avatar' and clone your voice, but this usually requires an Enterprise plan or a significant add-on fee. It’s worth it if you’re the 'face' of your company and need to scale your presence.
How long does it take to generate a video?+
Once you hit 'Generate,' it usually takes about 10–20 minutes to process a 5-minute video. It's significantly faster than waiting for a human editor to render files and send them back via WeTransfer.
Does it look obvious that it's AI?+
To a trained eye, yes. To an employee skimming a training video at 9:00 AM? Probably not. The mouth movements are incredibly accurate, but the 'soul' in the eyes is still about 90% of the way there. Use the 'Gestures' feature to make it look more natural.
Is there a limit on how many videos I can make?+
Yes. The 'Starter' plan (£15/mo) gives you about 120 minutes of video per year. If you're a heavy user, you'll need the 'Creator' plan (£52/mo) which offers 360 minutes. For most small businesses, the Starter plan is plenty to get through monthly internal updates.
Can I edit the video after it's generated?+
You can't 'edit' the rendered file, but you can change the script in the editor and re-generate it instantly. This is the biggest selling point—updating a video because a product feature changed takes minutes, not a re-shoot.
