The LEADTOOLS DVR Sink filter uses LEAD's intelligent time-shifting algorithm to write live video/audio streams to disk for playback. Developers have complete control of the buffer size including support to have the buffer span more than one disk.
- LEAD DVR Source
The LEADTOOLS DVR Source filter reads video and audio streams from files created by the LEADTOOLS DVR Sink filter. With the DVR Source filter, the LEADTOOLS Player control can play, pause, rewind and fast forward live streams.

Includes an “Auto Deinterlace” option to check the video for interlacing and apply deinterlacing only if necessary.
- LEAD Video Resize Filter
Resizes the video by adjusting the width and height of the frames using normal resize, resample bilinear, bicubic or Bresenham interpolation.

- LEAD H264 Encoder and Decoder
- Mechanism for smoother playback of corrupted video data.
- LEAD’s super compression option uses H.264 standard compression in an innovative way to produce super small streams using less resources when compared to other H.264 encoders. With this “super” performance it is possible to stream H.264 compatible videos in real time without additional hardware or excessive CPU usage making the super compression option ideal for video conference applications.
- Play high definition formats (720p and 1080i) in real time.
- User definable motion estimation settings controls the balance between encoder speed and quality.
- Multiple reference frames of any combination of past and future frames, providing precise interprediction as well as improved robustness during packet loss while streaming over the network or Internet.
- Unrestricted motion search uses reference frames that may be partly outside the frame improving network performance by predicting missing data.
- Only the difference between motion vectors is saved, increasing the compression ratio.
- Intraprediction may be performed either on 4x4 blocks or 16x16.
- Motion vector prediction is performed before the frame is prepared for compression (pre-DCT) improving prediction and compression performance.
- A context-sensitive deblocking filter smoothes out internal edges, significantly improving the visual quality of the video.
- Employs Context-Adaptive Variable Length Coding (CAVLC) to encode transform coefficients.
- The Context-Adaptive Binary Arithmetic Coding (CABAC) method continually updates frequency statistics of the incoming data and adaptively adjusts the algorithm, improving compression performance.
- Control of the number of frame types encoded into the video stream.
