RecordHTML / DOOH video

Record HTML5 creatives as DOOH-ready video

Turn an HTML5 creative into video for digital out-of-home screens. Set the native screen dimensions and exact frame rate, including 4416×1656 at 29.97 fps, with H.264 constant-bitrate controls for delivery.

This records a rendered animation or webpage; it does not preserve interactivity or download the original media from a site. For an original video, use the owner-provided download or export option.

Screen recording vs. frame-accurate recording

Manual screen capture

Desktop capture depends on your display resolution, window size, system load and when you press record. A busy machine can drop frames, and the start or end may need manual trimming. It can be useful for interactive walkthroughs, but matching an exact banner canvas takes extra preparation.

Configured browser recording

RecordHTML sets the viewport, output frame rate and recording length explicitly, then encodes the result with an exact frame count. It records real-time browser playback; it does not promise deterministic virtual-time rendering or that an overloaded creative cannot stutter. Test the animation, review the output, and use markers for repeatable timing.

Settings to check before delivery

Use even-numbered dimensions and match the original creative or destination screen. Video supports 23.976, 29.97 and 59.94 fps alongside whole-number options; GIF accepts whole numbers from 1 to 30 fps. Set the length within your account limit: the default is 60 seconds, while the recorder schema allows up to 300 seconds when configured. Choose audio for video only. Crop removes part of the viewport; scaling changes the output dimensions. GIF looping can be continuous or single-play, and final GIF output must not exceed 2,073,600 pixels, equivalent to 1920×1080.

Match the screen, not a standard video canvas

Digital signage and wide-format screens do not always fit 1920×1080. RecordHTML includes a 4416×1656 DOOH preset and accepts custom even-numbered dimensions. Record the HTML5 creative at the intended viewport, or use crop and output-size controls when the delivery canvas differs.

Use frame-accurate video timing

Choose the frame rate requested by the screen operator, including true NTSC rates of 29.97 and 59.94 fps. An exact frame count makes the recording repeatable. Use creative-controlled trim_start() and trim_end() markers to identify the part of the animation to keep.

Set encoding to the placement specification

The 4416×1656 preset suggests 29.97 fps and 15 Mbps CBR. These are starting settings, not a universal DOOH standard. Select MP4 for H.264 output, then match the operator requirements for bitrate, pixel format, duration and audio. Your account limits apply, and the screen operator should validate the final file.

How it works

Get the screen operator delivery specification and provide the hosted URL of your HTML5 creative.
Choose the DOOH 4416×1656 preset or enter the native dimensions. Set MP4, the required frame rate, duration and encoding.
Record, preview and download the video. Check its dimensions, playback and encoding against the operator specification before delivery.

Frequently asked questions

Can I record 4416×1656 at 29.97 fps?: Yes. The DOOH preset selects 4416×1656 with a 29.97 fps hint and 15 Mbps CBR. These settings can be adjusted, subject to your account limits.
Is 15 Mbps CBR required for every DOOH screen?: No. Each screen network has its own specification. Confirm the required bitrate, codec, frame rate, dimensions and duration with the operator, then configure your recording accordingly.
Can I use GIF for a full-size 4416×1656 screen?: Not at those output dimensions. GIF output is limited to 2,073,600 pixels and whole-number frame rates up to 30 fps. Choose MP4 for full-size 4416×1656 output at 29.97 fps.
Can I upload a ZIP from an HTML5 authoring tool?: Yes, when ZIP uploads are enabled on the deployment. Publish HTML5 output with index.html at the ZIP root and use relative asset paths. The current limits are 25 MiB compressed, 100 MiB expanded and 1,000 entries. Uploaded assets are publicly accessible to anyone with their link, so never include credentials or private material.
What is the maximum recording length, and can I include audio?: Your account limit is shown in the recorder; the default maximum is 60 seconds. The schema supports up to 300 seconds if configured. MP4 and WebM can include audio; GIF cannot. Confirm that the creative plays audio correctly and that the destination permits it before delivery.
Will WebGL work, and will the file fit an ad-network limit?: WebGL can run in the recording browser, but you should test the specific creative and its assets. No fixed output file-size guarantee is made. Video bitrate and duration affect size; GIF also depends on dimensions, frame rate and visual complexity. Check the destination specification and measure the downloaded file before submitting it.
