Video lesson coming soon. For now, follow the steps below.
To find out what works, compare versions of the same video that change just one thing: the opening, the final call to action, or the length. Izy builds the versions from the video you already have. From the same menu, you can create a version in another language, with translated voice.
Where to find it in Cognizy
Before you start
- Have a finished video, with script and narration: that's what the versions are made from.
- Each version that changes the narration uses credits; the screen shows the cost before creating it. The translation does too.
- To translate a video that shows people, you need their consent.
Step by step
- Step 1:
In , on the video card, click the actions button.
- Step 2:
In the menu, choose Create test versions to compare hooks, calls to action, and lengths, or Create version in another language to translate.
- Step 3:
In Versions to test, Izy suggests versions that each change just one thing: Hook, CTA or Length. Check the ones you want, turn on Build the versions next if you want the videos already assembled, and click Create 3 versions.
- Step 4:
The versions appear together in the library, next to the original, each with its own letter. Publish each one and compare the results.
- Step 5:
In Version in another language, choose the Language and How to translate: Quick, Precise, or Voice only. Fill in the consent for anyone who appears, and click Create in Spanish.
How to know it worked
The versions appear in the library together with the original video. The version in another language is ready within a few minutes and can be opened in the editor to adjust before assembling.
If something goes wrong
Izy couldn't create the versions.
The video needs to have a script and narration. Videos assembled only from files, without a script, have nothing to build versions from. Click Try again or choose another video.
The versions came out too similar.
Click Other versions to have Izy suggest again.
The translation only came out with voice.
Mouth translation wasn't available for that video. The version is ready with translated voice; for the mouth to match, try Precise mode.
I don't know which version won.
Publish the versions on similar days and times, and compare reach and responses in Promote › Posts and calendar.
Next step
Publish the versions and compare the results.
