ThankView captioning is done by humans and is 99% accurate! But in the case of the 1%, you can edit your captions.
On the VIDEOS page of the campaign setup, select which recipient's video you would like to edit (or "Select All" for every recipient). Once the video is selected, you can click "Edit Closed Captions."
Once you click on "Edit Closed Captions," a pop-up will give you the ability to edit the captions second by second.
You can also edit captions in the Video Library. Press Edit on the video that you would like to edit the captions on. Then, press Edit Captions on the toolbar below your video.
