it would be interesting to have the vertical and horizontal speeds in the SRT files.

Hi, RJn. Thanks for reaching out! Currently, both the Vertical and Horizontal Speeds aren't included but we'll forward this feedback to our developers. After the evaluation of the engineers, significant suggestions or requests will be implemented via the firmware update, app update, etc. For any updates, please stay tuned to the latest news on our DJI official website at www.dji.com or by checking the Release Notes specific for the DJI Air 2S.
