The short version
Positioning
Viedoc is commonly shortlisted by mid-size sponsors, CROs and academic groups who want a modern cloud EDC and are comfortable with partner or vendor help for build and validation. A reviewer on one aggregator noted a missing feature in a specific form type, which illustrates why a feature checklist against your protocol matters more than reviews.
Rave is often the default where the CRO or the sponsor's data management group has standardised on it. That ecosystem brings experienced builders, familiar processes and the weight that comes with them. For a single study, the question is whether that weight adds value or only cost and calendar time.

Evaluation
Send the same list to every vendor and keep the answers in writing.
| Topic | Question | What Capture offers for comparison |
|---|---|---|
| Build | Who builds our eCRFs, how long does it take, and is a partner or service required? | You build it. The AI study builder drafts visits and forms from an uploaded protocol; nothing saves without human review. |
| Amendments | How are mid-study amendments handled, tested and billed? | Forms move from draft to approved; approved forms are locked for live use. |
| Patient-reported data | Are questionnaires in the same study and audit trail as site data? Which instruments are supported? | ePRO shares one study and audit trail with EDC; licence fields exist for patient questionnaires, and licences are not verified by Capture. |
| Consent | Is consent captured in the same record, with signatures tied to document content? | eConsent with email-OTP signatures cryptographically linked to the document. |
| Data cleaning | How are checks, queries and SDV configured? | Edit checks raise auto-queries; SDV is set per field. |
| Exports | What do we receive at lock and exit? | CSV/Excel with data dictionary; audit trail; SDTM as SAS XPT with Define-XML. |
| Validation | What validation documentation is supplied? | Enterprise customers receive documentation to support sponsor validation and UAT. |
| Total cost | What are all charges over 24 months for our enrolment? | Core from $1,000/month with one live study plus $50 per participant per month; see the pricing page for current terms. |
Capture rows are from the Capture pricing page and product pages. Vendor columns are deliberately blank: ask Viedoc and Medidata directly.

Hands-on test
A diary is where mid-market and enterprise differences often surface. Take one visit with site vitals and a participant diary, and ask each vendor to build both with a range check. Count the modules, people and days. This is a demo-data example of the site side in Capture.

Decision aid
Rave is the comparator; ask what changes if you bring the study in-house.
Test Viedoc with Viedoc Me and a lean option on the same visit.
Ask for amendment turnaround and price in writing from all three.
Weight self-serve build and sandbox access heavily.
Check site count, support hours and validation documents, then test Capture's Phase 3 controls.
Process
Same enrolment, sites, modules and two amendments to all vendors; ask for 24-month pricing.
Include a range check and a calculated field; count people and days.
Compare answers on validation, exports and support, and total cost.
Switching
See how to migrate from Viedoc, how to migrate from Medidata Rave and how to switch EDC vendors mid-study. For cost structure, see the EDC software pricing guide. Related pairings: Castor vs Medidata Rave and iMedNet vs Medidata Rave.
Neither wins in general. Rave is built for large programmes with specialist builders; Viedoc is a cloud EDC often evaluated by mid-size sponsors and CROs. Test both with the same visit and a written scenario.
We do not quote either vendor's pricing because we cannot verify it. Ask both to price the same enrolment, sites and modules, and compare the 24-month total.
Trade profiles name Viedoc Me as its eCOA/ePRO offering. Confirm current modules and whether your instruments are supported directly with Viedoc.
Medidata is a subsidiary of Dassault Systèmes, as its own press releases state.
Because a self-serve option with a free sandbox is quick to test. Capture combines EDC, ePRO, eConsent and randomization in one audit trail and publishes its pricing.
Yes. Capture supports Phase 1 through Phase 3, including SDV per field, freeze and lock, blinded roles and multi-site filtering.
Send identical written questions to every vendor, build one real visit with a diary, an edit check and a calculated field in each, and compare people involved, elapsed time and 24-month cost.
Build the same visit in Capture, free. No credit card; you pay only at go-live.
