# Adaptive Bitrate Streaming

Adaptive Bitrate Streaming (ABR) delivers the best possible video quality based on each viewer’s network conditions. Vidinfra automatically generates multiple resolutions during transcoding and streams them using **`HLS`** and **`DASH`**, ensuring smooth playback with minimal buffering.

ABR is a core part of Tenbyte’s video delivery workflow, improving performance across devices and adapting reliably to changing network speeds, especially on mobile connections.

## Open Transcoding Settings

* From the left sidebar, open the Settings dropdown and select Transcoding.

* This opens the transcoding dashboard, where you will see the default transcoding profile.

* To edit it, click the three-dot menu next to the profile and choose **Edit**.

* You will be taken to a new dashboard where you can adjust all transcoding options.

## ABR in Vidinfra

When Adaptive Bitrate (**`HLS`** + **`DASH`**) is selected in the transcoding profile:

* Vidinfra creates multiple output resolutions (e.g., **`240p`**, **`360p`**, **`480p`**, **`720p`**, **`1080p`**).
* Each resolution is encoded separately using the selected codec (**`H.264`** or **`H.265`**).
* The player automatically switches between these qualities during playback.
* Viewers on strong networks get high-quality video, while slower networks receive lower resolutions for uninterrupted viewing.

ABR in Vidinfra uses:

1. **`HLS`** (HTTP Live Streaming)
2. **`DASH`** (Dynamic Adaptive Streaming over HTTP)

These formats allow the player to request segments of different qualities in real time based on available bandwidth.

### Video Codec

A video codec compresses a video into a smaller file for storage and streaming, then decompresses it during playback so the viewer can watch it smoothly.

1. `H.264` (AVC)
   `H.264` is the default codec used in Vidinfra. It offers a strong balance between video quality and file size and is supported across all major devices, browsers, and players.

2. `H.265` (HEVC)
   `H.265` provides higher compression efficiency compared to H.264, meaning it can deliver similar quality at a smaller file size.

### Video Output Resolution

Vidinfra lets you choose the set of resolutions generated during transcoding.

</Frame>

Available output options include:

1. **240p (EGA 352 × 240)**: Ideal for low-bandwidth environments and basic mobile connectivity.
2. **360p (nHD 640 × 360)**: Good for medium-bandwidth users while keeping file sizes small.
3. **480p (ED 842 × 480)**: Standard-definition quality suitable for most general-purpose playback.
4. **720p (HD 1280 × 720)**: High-definition output for users with stable network connections.
5. **1080p (FHD 1920 × 1080)**: Full HD resolution for high-quality viewing on larger screens.
6. **1440p (QHD 2560 × 1440)**: Quad HD quality that offers sharper detail than 1080p.
7. **2160p (UHD 3840 × 2160)**: Ultra HD resolution designed for premium viewing.

### Per-Title Encoding

It analyzes each video and adjusts the bitrate ladder, so that every resolution uses the lowest possible bitrate without losing quality.

</Frame>

<Note>Per-Title Encoding is not ABR, but it fine-tunes the quality and bitrate of each ABR resolution to deliver the best visual result at a smaller file size.</Note>
