Hey everyone! 👋 I've been deep in the weeds with Descript for a few months now, mostly for short clips and social media content, and I love its transcript-based editing workflow. But my team just wrapped up a virtual conference, and we're staring down about 40 hours of recorded sessions—each one 45-90 minutes long. The promise of editing by just deleting text blocks is incredibly tempting for a project of this scale.
I'm considering a full plunge into using Descript as the primary editor for these long-form recordings, but I'm wary of potential performance pitfalls and workflow hiccups. I'd love to hear from anyone who has actually been in the trenches with it for similar marathon editing sessions.
Some specific things I'm curious about:
* **Performance & Stability:** How does Descript handle, say, a 2-hour, multi-speaker video file on a reasonably powerful machine? Does scrolling through the transcript or timeline become laggy?
* **Speaker Detection & Transcript Accuracy:** For long recordings, how well does the AI maintain consistent speaker labels? Did you find the automatic transcript accurate enough to trust for editing, or did you need to invest heavily in manual correction first?
* **Editing Workflow Nuances:** Any gotchas when making large deletions (like removing a 30-minute Q&A) or rearranging huge chunks? Does the "remove filler words" feature work reliably at length, or does it risk mangling important content?
* **Export & Handoff:** Finally exporting such a large, edited project—were there any issues with render times or file synchronization, especially if you pulled the edited audio into another DAW or video suite for final finishing?
I plan to document my own process as a sort of case study, including any middleware or automation I set up (maybe using webhooks or Make to handle file transfer from our recording platform). But I'd hugely value hearing your real-world experiences and any integration recipes you might have developed along the way.
If you've done this, what was your overall stack? Did you use Descript for the entire edit, or just as a powerful first-pass tool? Any and all details would be amazing.

I've been down that exact road with a 30-hour workshop series last year. Let's just say the transcript accuracy for technical content, especially with domain-specific terms or accented speakers, was... optimistic. The promise of editing by text is seductive, but you'll spend more time correcting the transcript than you would have just cutting the timeline in a traditional editor.
On performance with 90-minute files: it's fine on a Mac Studio, but the speaker detection becomes a mess after the first hour if you have audience Q&A or panel cross-talk. Labels start switching arbitrarily. You'll be doing a lot of manual reassignment, which defeats the entire time-saving premise.
Your k8s cluster is 40% idle.
Yeah, the speaker detection drift is real. It's like the system gets tired after an hour and starts guessing. I've found it helps to create separate tracks for each speaker in your raw footage *before* importing into Descript, then using those as the source. It's an extra step, but it saves the headache of reassigning everything later.
On a separate note, how did you handle the transcript corrections for domain terms? Did you find building a custom vocabulary list made a tangible difference, or was it still a manual slog?
Dashboards or it didn't happen.
Great point about pre-separating tracks. That's a solid, practical mitigation. It's the kind of upfront work that often gets overlooked in the rush to just "drag and drop," but it pays off in spousal sanity later.
On your question about custom vocabulary, my experience has been mixed. For a consistent set of product names or acronyms, adding them definitely helps the initial transcript. But if you have a lot of varied jargon, it can still be a manual slog to correct - the list helps it recognize the *word*, but not necessarily the *context*, so you still get some odd substitutions. It cuts down the work, but doesn't eliminate it.
Keep it constructive.
Oh wow, 40 hours is a lot. I'm actually in a similar spot, just starting with a much smaller batch of recordings.
Your question about performance on a "reasonably powerful" machine hits home. I'm on a 2020 M1 MacBook Pro, and I noticed the timeline gets a bit choppy with files over an hour, especially when I'm scrubbing. It's not terrible, but it's not as smooth as with my 15-minute clips. Maybe someone with a newer M3 machine can chime in.
And on speaker labels - that's my biggest worry too. I had two speakers on a 70-minute call, and the AI swapped their labels three times for no clear reason. It made editing by text really confusing. Is there a setting for that, or is it just a known bug?
