Same picture in. Same picture out.
The preview is your video, not a stand-in. The quality number from that file is on screen before you save. The video you get back is made to that number, and we show it again when the file is ready.
- The picture stays on this device. The sound is sent to write the words, and it is not kept.
- A caption file does not rewrite the original. SRT works in Resolve, Premiere, and CapCut. ASS keeps the styling you set here.
- Words on the video stay in the frame if you crop it later. A caption file is a track you trim with the clip.
- When the format allows, the sound is copied across, not recorded again.
- If a file does not say its quality, we tell you and use a high setting instead of squeezing the picture.
- The next video opens with the same look. Show one, two, or three words at a time, and drag them where you want.
Captions are free.
The caption file and a video with the words burned in are free. This device can send 40 minutes of audio a day. A pass already bought still works. The other prices here are what those tools charge.

$295
once, to generate subtitles inside Resolve

Questions
Is KineticCaptions a free caption generator?
Word-by-word captions are free. The caption file and a video with the words burned in are free. This device can send 40 minutes of audio a day. A pass already bought still works. New passes are not for sale.
Will this reduce the quality of my video?
A caption file does not touch the video. A video with the words on it is a new file at the same picture size, frame rate, and quality number we read from yours. That number is on screen before you save, and again when the file is ready. If the file does not include a quality number and we cannot work it out from the size and length, the new video uses 50 Mbps and we say so.
Can I use the captions in DaVinci Resolve, Premiere, or CapCut?
Yes. Take the caption file and drop it on the timeline. Free Resolve can import that file. It cannot create one. Without the file you type every line and set every time yourself, or you pay $295 for Resolve Studio.
Do you upload my video?
The picture stays on this device. The sound is sent to write the words, and it is not kept.
What if I want the words already on the video?
Save “Video with captions.” You get a new file with the words in the picture, at the same quality. Cropping that video later crops the words with it.
Can the transcript get a word wrong?
Yes. Click a word to hear that moment and double-click to fix it before you save or post.
