A video CDN for streaming is the delivery layer that serves video segments from servers near each viewer, so playback starts fast and holds its quality under load. Flicknexs includes that delivery layer and a bandwidth allowance in every plan, serves adaptive-bitrate HLS, expires playback links through signed URLs, and configures referer protection on request.
Flicknexs provides video cdn as part of its white-label OTT platform. Flicknexs delivers every title as adaptive-bitrate HLS through an included delivery layer, with a signed-URL flag and time-to-live in storage settings and a bandwidth allowance stated per plan on our pricing page.
Why the video CDN for streaming is the part of the bill you should understand
Storage is cheap and predictable. Delivery is neither, and it is where streaming services get surprised. Every minute a viewer watches pulls megabytes from a server, and the cost of moving those bytes to a phone in another country scales with your audience, not with your catalog. An operator who does not know the bandwidth allowance in their plan, the size of their renditions and the average watch time per session cannot forecast the one line on the bill that grows with success. This page exists so you can do that sum before launch rather than after the first big month.
Flicknexs treats delivery as part of the platform rather than a separate account you must open. Each plan carries a stated bandwidth allowance alongside its storage, transcoding produces adaptive-bitrate HLS with a master playlist, and the delivery layer serves the segments to the web player and every device app. The signed-URL flag and its time-to-live live in storage settings. Hotlink protection by referer is configured at the delivery layer on request. There is no separate delivery contract, no per-region pricing table and no second dashboard to reconcile against your invoice.
Two public references explain the mechanics this page relies on. The HTTP Referer header, documented on the Mozilla Developer Network, is what hotlink protection reads to decide whether a segment request came from your player or from a page that embedded your stream without permission. The HLS specification published by the IETF as RFC 8216 defines the master playlist, the media playlists and the segment format that the player fetches. Understanding both takes an hour and pays off the first time a support ticket says a video works on one site and fails on another.
What the Flicknexs delivery layer does with each request
Everything in this table is either in the platform code or configured at the delivery layer as noted. The bandwidth figures come from our pricing page.
Adaptive HLS
Each title is packaged as HLS with a master playlist listing every rendition.
Included delivery
Segments are served through the delivery layer that comes with every plan.
Bandwidth per plan
Each plan states a bandwidth allowance next to its storage on our pricing page.
Signed URLs
A storage setting turns on signed playback URLs with a time-to-live you choose.
Referer protection
Hotlink protection at the delivery layer allows only approved domains and apps, set up on request.
Entitlement first
Plan, purchase, preview and country rules are checked before any playback URL is issued.
Live and on-demand
Live streams and on-demand titles use the same HLS delivery and the same player.
Session analytics
Player sessions record watch time, completion and device, which drive the bandwidth forecast.

How the video CDN for streaming works on Flicknexs
From the upload to the last segment, here is the path a title takes and what the admin controls along the way.
Transcoding produces the renditions the delivery layer serves
The player fetches a master playlist and then segments
Signed URLs put an expiry on every playback link
Referer protection checks where the request came from
Bandwidth is counted against the plan allowance
Live streams travel the same path
How to set up delivery in the Flicknexs admin
Five steps that take an afternoon, most of it spent on the forecast rather than the settings.
- 1
Pick the plan whose allowance fits your forecast
Estimate monthly watch-hours from your expected audience and average session length, multiply by the bitrate of the rendition most viewers will land on, and compare the result with the allowance in each plan sentence on our pricing page. Choose the plan that leaves headroom for a good month, and note whether its allowance is stated per month or per year.
- 2
Set the rendition ladder to match the content
Open the transcoding settings and choose the ladder. The default of 720p, 480p and 360p suits most catalogs; add higher renditions only where the source and the audience justify the bandwidth. Upload a test title and note the size of each rendition in the job record, because those numbers feed the forecast from step one.
- 3
Turn on signed URLs and set the time-to-live
In Settings, then Storage, switch the signed-URL flag on and enter a time-to-live in seconds. Films and live events suit a short window; long lectures suit a longer one so a paused viewer does not lose the link. Save, then play a test title in a private browser and confirm it starts and that a copied link fails after the window.
- 4
Request referer protection with your domain list
Write down every domain that hosts your player, including staging and any marketing microsite, and ask the Flicknexs team to configure hotlink protection at the delivery layer with that list. The native apps are included in the setup. Add this list to your launch runbook so a future microsite is added before it goes live rather than after it fails.
- 5
Watch the usage reports for the first month
Open the analytics reports for player sessions, watch-hours by user and device breakdown after the first week of traffic. Compare the observed bandwidth with the forecast, identify the titles and devices that dominate, and adjust the ladder if a mobile-heavy audience is being served renditions it cannot display. Repeat monthly until the forecast and the bill agree.
Limits and tradeoffs of the video CDN for streaming
What the delivery layer does not do, said plainly so your architecture review has no surprises.
Bring-your-own delivery is not offered on the plans
One delivery layer, not several
HLS only, and the manifest is not token-authenticated
The allowance is a number, and traffic above it needs a conversation
Referer protection needs a maintained list and a request

Pre-launch checklist for delivery
Ten checks that take an hour and prevent the most common first-month surprises.
- You know whether your plan states its bandwidth allowance per month or per year, and the number is in your launch spreadsheet.
- A written forecast multiplies expected watch-hours by the bitrate of the rendition most viewers will land on, per device type.
- The rendition ladder matches the content and the audience, and the size of each rendition from a real job is recorded.
- The signed-URL flag is on in storage settings and a copied playback link fails after the time-to-live you chose.
- Referer protection has been requested with a complete domain list that includes staging and every marketing landing page.
- A test title plays on web, on a phone and on one television app, and the player switches renditions on a throttled connection.
- A live test stream has been run through the same delivery path with the entitlement check and pay-per-view rule that the real event will use.
- The analytics watch-hours, completion and device breakdown reports are bookmarked and someone owns the monthly comparison against the forecast.
- You have asked in writing what happens if traffic exceeds the allowance, and the answer is filed with the plan contract.
- Support knows that a video which works on your site but fails on a partner site is usually a referer list issue, not an outage.
How the delivery layer interacts with the device apps and your revenue
The same delivery path serves every screen, and the bandwidth it consumes is the cost side of every plan and purchase you sell.
