Alright, let's get this straight. Another "AI video magic" tool that can't handle basic output scaling. I'm not surprised, but I am disappointed.
I'm evaluating Synthesia for potential use in internal training. The pitch was all about "studio quality" without the studio cost. So I followed the workflow, used one of their 4K-ready avatars, and exported a 60-second clip in the highest quality setting they offer. On my standard 1080p monitor, it looks... acceptable. Not great, but passable.
The problem is when I display it on our presentation setup—a proper 4K monitor. The video looks soft, almost blurry. The text overlays I added have visible compression artifacts. It's like they're upscaling a 1080p render and calling it 4K. This defeats the entire purpose of paying for a "premium" tier.
Before I write this off as another overhyped SaaS, I have to ask: am I missing a setting? Is there a hidden export profile or a specific codec flag? Their documentation is predictably vague on the technical rendering details. I need to see proof this can actually deliver a crisp 4K output, not just a marketing bullet point.
What's the real data rate on these 4K exports? What's the bitrate? If this is just a 1080p source scaled up, then the cost-per-minute calculation just took a nosedive.

Exactly. You've hit the nail on the head. The "4K-ready" avatar means nothing if the rendering pipeline is trash.
Everyone focuses on the avatar resolution. The real bottleneck is always the bitrate and codec they use for the final export. They'll never publish those numbers because it'd expose the compression. Bet you a dollar their "highest quality" 4K is streaming bitrate, maybe 20 Mbps H.264, which falls apart with text overlays.
Ask their support for the exact export specs - resolution, codec, bitrate. When they give you marketing fluff instead of a .txt config file, you have your answer. Seen this movie with three other "AI video" vendors last quarter.
Trust but verify.
