Video Upload and Compression Tips What types of video files does Ensemble Video allow? Acceptable video formats include avi, m4v, mov, mp4, mpeg, mpg, QT, wmv and many more! Here is a complete list of supported formats. For best results, try to encode videos using our video compression guidelines. These basic principles will apply to almost all of the video programs out there. Video Codec: H.264/MP4 A codec is the format in which your video will be encoded. Different codecs have different features and varying quality. For best results, we recommend using H.264 (sometimes referred to as MP4). Frame Rate: 24, 25, or 30 FPS If you know at which frame rate you shot, it is best to encode at that same frame rate. However, if it exceeds 30 FPS (frames per second), you should encode your video at half that frame rate. For example, if you shot 60 FPS, you should encode at 30 FPS. If you're uncertain what frame rate you shot at, set it to either "Current" or 30 FPS. If there is an option for keyframes, use the same value you used for frame rate. Data Rate: 2000 kbps (SD), 5000 kbps (HD) This setting controls both the visual quality of the video and the file size. In most video editors, this is done in terms of kilobits per second (kbps). Use 2000 kbps for standard definition or 5000 kbps for high definition video. Resolution: 640x480 (SD), 1280x720 (HD) 640x480 for 4:3 SD video, 640x360 for 16:9 SD video, and 1280x720 or 1920x1080 for HD. If you have the option to control the pixel aspect ratio (not the display aspect ratio) make sure it's set to "1:1" or "1.00", sometimes referred to as "square pixels." Deinterlacing: Maybe If you are shooting on an older camera, enable this option. Otherwise, you may get weird-looking horizontal lines in your video. With newer camera models this won't matter, so you can leave this option unchecked. Audio Codec: AAC (Advanced Audio Codec) For best results, we recommend using AAC for the audio codec. Data Rate: 128 -256 kbps Export you audio at the highest quality audio data rate possible. Sample Rate: 44.1 kHz 44.1 kHz is the highest audio sample rate we currently support.

MPEG Video in Software: Representation, Transmission, and Playback
High Speed Networking and Multimedia Computing, IS&T/SPIE Symp. on Elec. Imaging Sci. & Tech., San Jose, CA, February 1994. MPEG Video in Software: Representation, Transmission, and Playback Lawrence A. Rowe, Ketan D. Patel, Brian C Smith, and Kim Liu Computer Science Division - EECS University of California Berkeley, CA 94720 ([email protected]) Abstract A software decoder for MPEG-1 video was integrated into a continuous media playback system that supports synchronized playing of audio and video data stored on a ﬁle server. The MPEG-1 video playback system supports forward and backward play at variable speeds and random positioning. Sending and receiving side heuristics are described that adapt to frame drops due to network load and the available decoding capacity of the client workstation. A series of experiments show that the playback system adds a small overhead to the stand alone software decoder and that playback is smooth when all frames or very few frames can be decoded. Between these extremes, the system behaves reasonably but can still be improved. 1.0 Introduction As processor speed increases, real-time software decoding of compressed video is possible. We developed a portable software MPEG-1 video decoder that can play small-sized videos (e.g., 160 x 120) in real-time and medium-sized videos within a factor of two of real-time on current workstations [1]. We also developed a system to deliver and play synchronized continuous media streams (e.g., audio, video, images, animation, etc.) on a network [2].Initially, this system supported 8kHz 8-bit audio and hardware-assisted motion JPEG compressed video streams.

Video Coding Standards
Module 8 Video Coding Standards Version 2 ECE IIT, Kharagpur Lesson 23 MPEG-1 standards Version 2 ECE IIT, Kharagpur Lesson objectives At the end of this lesson, the students should be able to : 1. Enlist the major video coding standards 2. State the basic objectives of MPEG-1 standard. 3. Enlist the set of constrained parameters in MPEG-1 4. Define the I- P- and B-pictures 5. Present the hierarchical data structure of MPEG-1 6. Define the macroblock modes supported by MPEG-1 23.0 Introduction In lesson 21 and lesson 22, we studied how to perform motion estimation and thereby temporally predict the video frames to exploit significant temporal redundancies present in the video sequence. The error in temporal prediction is encoded by standard transform domain techniques like the DCT, followed by quantization and entropy coding to exploit the spatial and statistical redundancies and achieve significant video compression. The video codecs therefore follow a hybrid coding structure in which DPCM is adopted in temporal domain and DCT or other transform domain techniques in spatial domain. Efforts to standardize video data exchange via storage media or via communication networks are actively in progress since early 1980s. A number of international video and audio standardization activities started within the International Telephone Consultative Committee (CCITT), followed by the International Radio Consultative Committee (CCIR), and the International Standards Organization / International Electrotechnical Commission (ISO/IEC). An experts group, known as the Motion Pictures Expects Group (MPEG) was established in 1988 in the framework of the Joint ISO/IEC Technical Committee with an objective to develop standards for coded representation of moving pictures, associated audio, and their combination for storage and retrieval of digital media.

Flow Imaging LOGIQ E10 Series
WHITEPAPER Flow Imaging LOGIQ E10 Series Introduction Ultrasound can be a highly desirable imaging tool to assess flow hemodynamics due to its lack of ionizing radiation, real-time nature, portability, and economy. To address the wide-ranging clinical needs of various specialties, GE Healthcare has made a variety of flow technologies available on the LOGIQ™ E10 Series ultrasound systems, including: • Color Flow • Power Doppler Imaging • Microvascular Imaging • Radiantflow™ • B-Flow™ Imaging This paper will review the technical aspects and clinical benefits of each flow technology. Color Flow Introduction The color flow (CF) mode allows the visualization of flow direction Figure 1 shows CF (light blue, inside the ROI) and background and velocity information within the region of interest (ROI), B-Mode (gray), which are generated by separated transmit (Tx) or color box, defined by the operator. The Doppler shifts waveforms and received (Rx) echoes. The entire CF frame is of returning ultrasound waves within the ROI are color-coded created by overlaying CF information onto the background B-Mode. based on average velocity and direction. A wall motion filter (WMF) is always applied to differentiate true flow and clutter. How CF Works Similar to Pulsed Wave (PW) Doppler, CF utilizes intermittent Tx* & Rx sampling of ultrasound waves, and avoids the range ambiguity of Continuous Wave (CW) Doppler. Flow is depicted in blue when traveling away from the transducer (negative Doppler shift), while flow traveling toward the transducer (positive Doppler shift) is depicted in red. Lighter shades of each color denote higher velocities. The areas of high flow turbulence are depicted in a third color.

A Multiplierless Pruned DCT-Like Transformation for Image and Video
A Multiplierless Pruned DCT-like Transformation for Image and Video Compression that Requires 10 Additions Only Vitor A. Coutinho ∗ Renato J. Cintra Fábio M. Bayer† Sunera Kulasekera Arjuna Madanayake‡ Abstract A multiplierless pruned approximate 8-point discrete cosine transform (DCT) requiring only 10 ad- ditions is introduced. The proposed algorithm was assessed in image and video compression, showing competitive performance with state-of-the-art methods. Digital synthesis in 45 nm CMOS technology up to place-and-route level indicates clock speed of 288 MHz at a 1.1 V supply. The 8 × 8 block rate is 36 MHz. The DCT approximation was embedded into HEVC reference software; resulting video frames, at up to 327 Hz for 8-bit RGB HEVC, presented negligible image degradation. Keywords Approximate discrete cosine transform, pruning, pruned DCT, HEVC 1 Introduction The discrete cosine transform (DCT) plays a fundamental role in signal processing techniques [1] and is part of modern image and video standards, such as JPEG [2], MPEG-1 [3], MPEG-2 [4], H.261 [5], H.263 [6], H.264/AVC [7, 8], and the high efficiency video coding (HEVC) [9, 10]. In particular, the transform coding stage of the H.264 and HEVC standards employs the 8-point DCT of type II [10,11] among other transforms of different blocklenghts, such as 4, 16, and 32 points [12–14]. In [15], the 8-point DCT stage of the HEVC was optimized. Among the above-mentioned standards, the HEVC is capable of achieving high compression performance at approximately half the bit rate required by H.264/AVC with same image quality [10,13,15,16].
