Strategic Summary
Overview
Synthesia and Descript both solve the video creation bottleneck that drains marketing teams, but they approach the problem from opposite directions. Synthesia is a synthetic video platform—it generates video from scripts using AI avatars, templates, and voice synthesis. Descript is a video editor built on transcript-first workflows, letting you edit video by editing text, then synthesizing voiceovers. For CMOs evaluating these tools, the choice hinges on whether your operational debt lives in script-to-video production (Synthesia) or in video editing and voiceover iteration (Descript). Both promise speed, but they solve different friction points in your workflow.
Synthesia is purpose-built for teams that need to produce high-volume, personalized, or templated video at scale. You write a script, pick an avatar and voice, and the platform generates a finished video in minutes. This is ideal for product demos, training content, localized campaigns, or personalized customer videos. The ROI lever here is clear: replace expensive video production cycles with template-driven generation. Synthesia's strength is repeatability—if you're producing 50 variations of the same message for different segments or regions, Synthesia compounds fast. The trade-off is creative control; you're working within the platform's avatar and template constraints.
Descript is built for teams that already shoot video or work with video assets, and need to compress the editing and revision cycle. Its core insight is that editing video by editing text is faster than timeline scrubbing. You upload video, Descript transcribes it, you edit the transcript (removing filler words, reordering sections), and the video follows. Voiceover synthesis fills gaps or replaces sections. This workflow is powerful for interviews, podcasts, webinars, and founder-led content where the raw material exists but editing is the bottleneck. Descript also doubles as a collaboration tool—non-video editors can participate in the revision process through text. The trade-off is that Descript works best when you have source video; it's less useful if you're starting from a blank script.
Our Recommendation: Synthesia
Synthesia wins for most marketing teams because it directly addresses the operational debt that blocks video production at scale. While Descript excels at editing existing video, most marketing teams' constraint is creating video from scratch without expensive production cycles. Synthesia's avatar-based generation removes the production dependency entirely, making it the faster ROI lever for CMOs trying to prove AI impact in 90 days.

Choose Synthesia when...
Choose Synthesia if your team produces high-volume, templated, or personalized video content (product demos, training, localized campaigns, customer testimonials). Also choose Synthesia if you lack in-house video production capability and need to eliminate the external vendor dependency. Synthesia's ROI is fastest when you can measure output velocity (videos per week) and pipeline impact (demo views, training completion).
Choose Descript AI when...
Choose Descript if your workflow already includes video creation—interviews, webinars, founder content, podcasts—and your bottleneck is editing, revision, and voiceover work. Descript is also the better choice if you need collaborative editing where non-technical team members (product, sales) participate in trimming and refining. Use Descript when your operational debt is in the post-production phase, not the production phase.
