Axinom Encoding - FAQ

General

What is Axinom VIP?

After the latest release, Axinom VIP was renamed to Axinom Encoding. This makes Axinom VIP the predecessor of Axinom Encoding.

Trivia: "VIP" is an abbreviation for "Video Ingest & Processing".

What are the phases of encoding?

Processing an encoding job could take minutes or even hours. The job execution happens asynchronously. It involves several distinct phases, such as pre-validation, acquisition, media mapping, encoding, DRM protection, packaging, image extraction, and publishing. Read more about the different phases from the Axinom Encoding Overview article.

What codecs does Axinom Encoding support?

Axinom Encoding currently supports creating H.264/AAC and H.265/AAC adaptive bitrate streaming assets.

As input, it supports a broad variety of codecs and containers. Please find more information here:

Can Axinom Encoding produce DRM-protected content in line with studio requirements?

Yes.

Axinom DRM supports DRM protection across all output formats.

It offers granular control over the encryption process. Axinom Encoding offers important features to satisfy the latest content owner requirements:

  • Supports several content keys per asset

  • Separate content keys for different video quality levels

  • Separate content keys for audio

  • Uses modern CPIX standard for secure key material exchange

Which subtitles formats does Axinom Encoding support?

The supported subtitles formats include WebVTT, TTML, SubRip (SRT), and PAC.

Which packaging formats are used for the output?

The encoded video, audio, and subtitles could be packaged as MPEG DASH, HLS, or CMAF. The exact format is specified in the ContentProcessing section of a job description. Read more about content processing from the respective article.

Can I integrate Axinom Encoding with my existing workflows?

Yes.

One of our key goals for Axinom Encoding is interoperability. Another one is making it super easy for developers to integrate.

Axinom Encoding has a developer-friendly Web API and comes with comprehensive documentation and sample code. It supports standards, like CPIX, to ensure seamless integration. It also supports all major tools and protocols for acquiring source content and delivering the resulting output to its destination.

How can I encode videos without audio?

To encode a video without audio, you need to use a small inaudible (silent) audio file with the video. The audio track does not need to be the same length as the video. For instance, the audio track could be 1 second in length.

This approach also requires you to use the "AudioFileLanguageExpression" property inside the "MediaMappings"section of the job request. In such a case, the output would be a video stream as well as an audio stream, although the audio would be inaudible.

Read more about media mappings here: Media Mappings page.

How can I encode a video with embedded audio?

Embedded audios in video streams are supported and extracted as required. To encode a video with embedded audio, i.e. without a separate audio track, remove the AudioFileLanguageExpression property from the MediaMappings section of the job request. If the Axinom system supports the video file, it should automatically detect and map the embedded audio tracks. Each embedded audio stream must have a language tag with a valid language code in the metadata.

Security

I want to provide only certain resolutions for L3 security level. How do I do that?

You could customize it with the Entitlement Message by applying different policies with different Widevine device security levels to different keys. As L3 is the default, you can keep the default Widevine device security level for keys associated with L3 quality levels. Alternatively, you can explicitly specify L3 for reasons of clarity. For the keys that require a security level higher than L3, you need to specify it explicitly. Read about the Entitlement Message here.

Licensing

Can I try out your service free of charge?

Yes. Sign the service evaluation agreement in the My Encoding area to get a free 30-day trial for the Axinom Encoding Cloud product.

How is the price of encoding calculated?

Axinom’s billing model is based on processed minutes. The monthly bill groups the total output minutes by quality groups (SD, HD, UHD1, UHD2) and codecs (e.g. H.264, H.265). The minute price increases with the stream quality. Read more about the billing model or try out the pricing calulator. pricing calculator.
