When something goes wrong

Your internet connection is being blocked from the source, usually by an ISP or a network filter rather than by the app. A VPN normally fixes it. Settings also has a proxy field if you use one. If neither is an option, download the file yourself and load it from disk — that path always works.

Almost always the Gemini API key. Check it is pasted correctly in Settings with no trailing space, that the key is still active in Google AI Studio, and that you have not exceeded the free tier's rate limit — the fix for that is simply to wait a minute and retry.

If the source video has no captions of its own, the audio has to be transcribed, which takes longer and is less accurate on noisy recordings. Transcribed wording cannot be edited in the app today, so for a clip where a name comes out badly the options are to turn captions off for that one or to pick a different moment.

Encoding uses your processor, so the CPU decides the speed. A 30-second 1080p clip is typically well under a minute on a modern machine. Closing other heavy applications helps; rendering several clips at once does not, since they compete for the same cores.

Usually a source file the decoder cannot read properly — variable frame rate screen recordings are the common culprit. Re-encoding the source to a standard MP4 first fixes it. If it happens with an ordinary MP4, send us the file details.

Smart tracking follows the largest, most consistent face. Crowded or wide shots confuse that. Switch the clip to fit-and-blur so nothing is cropped, or open the frame editor and place the crop by hand.

Source downloads and rendered clips are both large, and a two-hour source can be several gigabytes. The app cleans up old downloads and clips automatically after a set number of hours; check the folder you pointed it at if space is still disappearing.
