Videokr technical questions answered
Videokr accepts MP4 and WebM uploads up to 200 MB and links to MP4, WebM, HLS (.m3u8), YouTube and Vimeo sources. Uploads are stored in object storage and delivered from Cloudflare’s edge network; embeds are a lazy-loaded iframe or a one-line script loader that adds no framework to your page. There are HMAC-signed webhooks and API keys, no self-hosted edition, and full export of videos, leads and analytics.
Formats and sources
Upload MP4 or WebM (200 MB per file, 5 MB per image), or link a source you already host: MP4, WebM, HLS .m3u8, YouTube or Vimeo. Linked sources stay where you host them and keep their own delivery. Details in sources.
Delivery
Uploads live in object storage and are served through Cloudflare's edge network with range requests, so seeking works and the player starts on the first bytes rather than the whole file.
Embedding
An iframe pointing at /e/VIDEO_ID, or embed.js with data-video which inserts a correctly-shaped responsive iframe and reports its own height for playlists. Both are lazy by default, so an embed below the fold costs the page nothing until it scrolls into view — the full parameter list is in embeds.
Page speed
The embed ships no framework onto your page and nothing renders until it is needed, which is why an embed does not move your Core Web Vitals the way a heavy player script does. See video page speed.
Automation
HMAC-signed webhooks fire on play, complete, CTA click and lead; API keys authenticate the WordPress plugin and your own integrations. See webhooks and API.
Frequently asked questions
What video formats does Videokr support?
MP4 and WebM for uploads (up to 200 MB per file), plus linked MP4, WebM, HLS (.m3u8), YouTube and Vimeo sources.
Does Videokr support HLS streaming?
Yes. You can link an HLS .m3u8 source and Videokr plays it in your branded player with the same analytics and marketing layers as an uploaded file.
Where are Videokr videos stored and delivered from?
Uploads are stored in object storage and delivered from Cloudflare’s global edge network. Linked sources stay wherever you host them.
Can I self-host Videokr?
No. Videokr is a hosted service with no self-hosted edition; there is no server for you to run. Your videos, leads and analytics can be exported at any time.
Will a Videokr embed slow down my page?
The embed is a lazy-loaded iframe (or a one-line loader that creates one), so it loads no framework onto your page and fetches the player only when it is needed.
Does Videokr have an API and webhooks?
Yes: API keys for programmatic access and the WordPress plugin, and HMAC-signed webhooks on play, complete, CTA click and lead events.
Can I use Videokr with React, Next.js, Webflow, Shopify or Framer?
Yes. Both embeds are plain HTML, so they work in any framework or website builder that allows an iframe or a script tag.
Can I export my data out of Videokr?
Yes. Leads export as CSV, analytics are readable per video, and your source files remain yours — nothing is locked in.
