Supported Output Format

We support the following video formats. You can deliver your video with any of them.

ABR

Adaptive-Bitrate output format lets you generate ABR streams from Gumlet. Gumlet automatically makes DASH and HLS streams available so you always get have them handy whenever needed.

HLS

HTTP Live Streaming (also known as HLS) is an HTTP-based adaptive bitrate streaming communications protocol developed by Apple Inc. Support for the protocol is widespread in media players, web browsers, mobile devices, and streaming media servers. Gumlet also recommends using this format for seamless video delivery and playback.

HTTP Live Streaming provides ways for video players to adapt to unpredictable network conditions changes without causing user-visible playback stalling. For example, on an unreliable wireless network, HLS allows the player to use a lower quality video, thus reducing bandwidth usage.

Any modern video player is capable of playing HLS stream produced by Gumlet. Most web players, iOS and Android devices support HLS playback. It's best choice for universal playback.

MPEG-DASH

Dynamic Adaptive Streaming over HTTP (DASH), also known as MPEG-DASH, is an adaptive bitrate streaming technique that enables high-quality streaming of media content over the Internet delivered from conventional HTTP web servers. Similar to HLS.

DASH is not supported in Apple products like iOS and Safari. This makes the HLS perfect choice as universally supported streaming standard.

MP4

MPEG-4 Part 14 or MP4 is a digital multimedia container format most commonly used to store video and audio. It allows streaming over the Internet. This is the most widely supported format and requires no extra player or javascript.

The downside of MP4 is that adaptive bitrate streaming is not supported, hence there will be subpar user experience and large data transfers.

Resolutions

If you have selected ABR as output, you can select resolutions that you want to generate.

MP4 Version

If you allow your users to download videos for offline view, generating MP4 version of the video helps. When you enable this option, we add MP4 stream in output which can be used to download the video for offline view.

Per-title Encoding

Gumlet analyzes each input video on a wide range of visual aspects. Based on the analysis, it chooses a unique set of transcoding options for processing the video. This ensures that the output video is of least size and best quality. We recommend to enable it but in future we are planning to put higher cost for videos which are encoded with per-title encoding technology.
