I also had this happen whilst shooting 29.97, the footage came out at 29 fps. What is going on with this camera?

Literally nobody knows? Where is tech support.

Tech support do not visit this forum, and they do not answer you. The only way to get technical help here is from the other furum members and aircraft owners.

Hi there. Thank you for reaching out and we're sorry for the trouble that this has caused. When the NTSC system is applied to black and white displays (Luma component), the frame rate is indeed 30 fps/60 Hz. However, after the chroma component is added, the subcarrier of the chroma component and the original brightness component are modulated. Due to the inconsistent frequencies, this will lead to the generation of a beat frequency. The solution is to change the frame rate to 30000/1001 (29.97) and 24000/1001 (23.98). This will greatly reduce the frequency at which the beat frequency is generated. This rule has remained a standard for CRT TVs. Hence, it is normal for a video shot at 24 fps to be displayed as 23.98 fps.Please find more details as follows which provided by NTSC :https://wiki.eanswers.net/en/NTSC?ext=t&cid=5036

Hope this helps. Thank you for your valued support.
