Hello,
We apologize for the inconvenience you’re experiencing with the Rank Math video schema and video sitemap. We understand that you’re facing issues with the auto-detection of video data from custom fields.
To ensure that Rank Math can detect videos present in custom fields, you need to specify the name of the custom fields to look for. This can be done in the Custom Fields option available under Rank Math SEO → Sitemap Settings → Video Sitemap.
If you’re unable to find the Custom Fields option under Video Sitemap settings, please make sure that you’re using the advanced mode of Rank Math. Once you’ve accessed the Custom Fields option, you can enter the name of the custom fields one per line.
Here’s a screenshot to guide you through this process:

It’s important to note that the Custom Fields option available under Titles & Meta Settings is used for page analysis, while the Custom Fields option available under Video Sitemap settings is used for detecting the presence of videos.
We hope this helps resolve the issue you’re facing. If you have any further questions or encounter any difficulties, please feel free to reach out to us.

Hello,
Thank you for your patience.
The Video Sitemap is available with Rank Math PRO but the account you have used to open this ticket is the Rank Math free version.
Can you please search and forward a receipt from FastSpring.com or the email address you used to purchase so we can locate your account and verify it?
Meanwhile, ensure that you have followed the steps to add the custom fields in Rank Math > Sitemap Settings > Video Sitemap > Custom fields.
Looking forward to helping you.

I add custom fields of course, I’m not as newbie as you mentioned. The problem is in rank math source codes.
Please accept that the problem is in the rank math source codes.
