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.
    Transcoding Configuration
  • 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.
    Transcoding Configuration
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.
Video Codec Configuration
  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.
Video Output Resolution
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.
Per Title Encoding
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.
