Need help?

My export stops partway through.
Exporting runs inside your browser, so it can stop if you close the tab or switch to another tab for a long time. Please keep this tab open until the export finishes. If only the saving step failed, press "Retry save" to save again without re-recording.
I edited the script, but the video hasn't changed.
Your edits appear in the video once you export again. Press "Export with changes" at the top right of the screen.
I want to fix how a word is pronounced.
Rewrite the script text the way you want it read (for example, spell numbers out). To have just part of it read in English, use "Language switch mode".
Can the text inside a PDF be translated too?
Text inside slides can only be translated for PowerPoint (.pptx) files. Subtitles and scripts can be chosen from 11 languages even for PDF materials.
I can't find the cancel button.
"Cancel" is shown only to the administrator of an organization on a card-billed plan. If you're a member, please ask your administrator. For contracts billed by invoice, please contact info@grab-design.com. The Free plan requires no cancellation.
I have a question about something else.
