Will my videos be subjected to copyright once my subscription ends?

Any licenced items will stay licenced under the same conditions. Licences do not exhaust by cancelling a stock subscription. You need, however, as @Jill_C suggests, the terms of your licence agreement, as not everything can be done and that independently of the fact that you have a licence or not.

If you have a Pro subscription, there are different limitations. Pro subscriptions are available, if I'm correctly informed, for Teams and Enterprise subscriptions.

You really should read and understand the License Terms yourself. However, in simple terms, you do not forfeit your rights to use an asset upon termination of your Adobe Stock account as long as you have complied with the terms that specify proper use of the asset.

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post if it helps you get responses.
