Hi - when I added my first video, it worked smoothly. I did a second (on the same page but further down) and both became zoomed-in blurry thumbnails and neither will play. I have had to remove them both and simply put up YouTube embeds. Please advise - is this just a glitch when two videos are on the same page? Thanks
Hi, I run a WordPress media network with automated RSS imports and YouTube embeds. I would like to know if KillerPlayer can automatically replace existing YouTube embeds inside imported WP posts, without manually inserting the player one-by-one. Specifically: 1.

A: Here is the link that discusses the absolute fastest way to embed the videos.

If I make videos for paid courses but upload the videos on YouTube, will they be safe and secure from unpaying people? Can I list the videos on YouTube as private/unlisted and still embed on a course via KillerPlayer? Or do the videos have to be Public? How's the safety against downloading the videos or sending the links of the videos to others?

A: Yes, absolutely. You need to upload the videos to YouTube and set them to Unlisted. Don't make them Public (obviously), but avoid Private too, because Private completely blocks embedding. Unlisted keeps them hidden from YouTube searches and your public channel feed, but still allows them to be embedded into your course.

"As a fellow user, I highly recommend this setup. I host my instructional videos on YouTube (unlisted) and run them through KillerPlayer. The security features are impressive, effectively blocking downloads and copying. I'm using Tier 1 right now and plan to upgrade soon. It’s a solid choice for anyone creating online courses."
Hey, thank you so much for the shout-out! It’s awesome to hear that the Unlisted + KillerPlayer setup is keeping your course content locked down and secure. We built this specifically to give creators elite protection without the massive hosting fees, so knowing Tier 1 is already delivering for you means a lot. Can't wait to have you on the higher tiers when you're ready to scale.

Q: Video language on YouTube
It is already common on YouTube to be able to choose the audio language.
1) Can I select the language? Since many videos are set by default in another language (which is not the language I want to hear)?
2) Is it possible to select the start and end time, or will it always be the full length of the video?
