Frequently asked questions

ELNA (Entertainment Live Network Arena) is a Windows application for running live quiz shows. It opens three windows — Operator, Contestant, and Broadcaster — that stay in sync on their own, so one operator can drive the questions, timer, and scores while clean pictures go to the audience screen and to air.

No. ELNA is one application with three windows on one PC. You can put each window on its own monitor, or send it to another PC over NDI.

Yes. Fill in the included Excel template (one tab per round) and import it; any problem is reported with the tab, row, and column to fix. A filled-in sample workbook covering every round type is included. You can also create quiz sets, rounds, and questions directly in ELNA and reorder them by dragging.

Six: multiple choice, Q&A, image, audio, video, and rapid fire. Marks and the timer are set per round. A round can go to one team, rotate through the teams, or have its team set per question; a rapid-fire round goes to one team.

In Settings › Scoring, each round type chooses how its option questions are scored: the reveal scores the option you marked, you judge with Y or N, or the reveal scores a marked option and you press Y or N when nothing was marked. A question without options is always judged with Y or N. Once a question is scored it stays scored; to correct a result, edit the team's score. Reset show sets the quiz set's scores to zero so every question can be played afresh.

Yes. Every Live control has a shortcut: next and previous step, show the next option, mark the contestant's answer, reveal, Y and N, the timer, blanking the outputs, and publishing the score board. Press ? on the Live screen for the full list.

Every feature, including audio and video questions and NDI output, for 20 minutes of live output per day, on up to 30 different days per PC. While the trial is running, the Contestant and Broadcaster pictures, and so their NDI feeds, carry an “ELNA Trial” watermark. Building and saving quiz sets is never limited.

No. The daily allowance counts live time across the whole day, so closing and reopening ELNA does not give you more. It resets when the date changes on your PC.

No. There is no sign-up and no licence file. Download ELNA, install it, and start.

ELNA blanks the outputs, stops its NDI feeds, and will not put new questions on air until the next day. Your saved quiz sets, teams, and settings are untouched, and you can keep editing them.

A licence removes the daily time limit, the 30-day limit, and the watermark.

Open the License page in ELNA and copy the Machine ID shown under This machine. Email it to contact@arsi.in with the name the licence should carry and how long you need it. We reply with the price and, after payment, a licence file. On the License page choose Install license file and pick it.

Each licence is tied to one PC through its Machine ID, a 64-character code that ELNA works out on that PC. If you need ELNA on several PCs, send one Machine ID per PC.

No. ELNA checks the licence on your PC and runs shows fully offline. It only goes online to look for updates, and only when a connection is available.

A hardware or Windows change can change the Machine ID. Send us the new Machine ID and we will issue a licence for it; existing licence files cannot be edited.

A licence works until the expiry date written in it. After a refund no further licences are issued for that purchase, but a licence file you already hold keeps working until its own expiry date.

ELNA refuses a licence if its signature is invalid, it was issued for a different PC, it has expired, the file has been changed, or the PC's clock has been moved back. The License page shows the specific reason.

Yes. Each window is its own NDI source — ELNA Operator, ELNA Contestant, and ELNA Broadcaster — that OBS (with the DistroAV NDI plugin), vMix, NDI Studio Monitor, and other NDI receivers can pick up. Open the window, switch on its NDI feed in Outputs, then add the source in your receiver. The ELNA installer includes the NDI 6 Runtime, so there is nothing else to install on the ELNA PC.

Every feed is sent at one fixed size, set in Outputs › NDI › Output size: 1920×1080 (the default), 1280×720, 3840×2160, or a custom size such as 1080×1920 for portrait screens. The feed keeps that size when a window is resized. If the Broadcaster window is too small for a sharp picture at that size, its NDI row says so.

First check that OBS on the ELNA PC itself can see the source. If it can, the network is the cause. Set the ELNA PC's network to Private in Windows: the installer allows ELNA through Windows Firewall on private and domain networks only, and third-party antivirus firewalls need ELNA.exe allowed separately. Many office and venue Wi-Fi networks also block NDI discovery; put the show PCs on their own switch or router, or point the receiving PC at the ELNA PC by name in NDI Access Manager › Remote Sources. ELNA shows its PC name on the License page.

Yes. The Broadcaster's background is see-through and the NDI feed carries that transparency, so the graphics sit over your video in any receiver that supports NDI with alpha.

Yes. Outputs has a theme editor for colours, sizes, corners, borders, and option animation, with a live preview. You can drag the Broadcaster's elements into place, separately for standard, audio, and rapid-fire rounds, and give pictures and videos a fixed frame shape (16:9, 4:3, 1:1 or 9:16), fitted or filled.

Yes. Each window can be moved to any screen and reopens where you left it.

64-bit Windows 10 version 1903 (the May 2019 update) or newer, and Windows 11. ELNA uses Microsoft Edge WebView2, which is part of Windows 11 and is normally already present on Windows 10. There is no macOS release yet.

ELNA offers a new version when one is published and installs it in place. Most updates can wait until later; an important one is marked required and must be installed before ELNA can be used again. The check only runs when you are online, so an offline show is never interrupted.

ELNA records the time of each successful licence check. If the PC's clock is later more than five minutes behind that time, the licence is refused until the clock is corrected. This is a local check; ELNA does not look up the time online.

Pictures, audio, and video are used from where they are on your PC, so a file that was moved, renamed, or left on another PC will be missing. The show carries on: the question goes on air without it, with a warning on your console. Choose the file again in the question and preview it before the show.

A window has to be open before its NDI feed can start. Open the Contestant or Broadcaster window, then switch its NDI feed on.

ELNA writes one log file per session, named after its start time, in %APPDATA%\in.elna.quiz\logs. The newest ten are kept. Send the latest one to contact@arsi.in when you report a problem.
