What is the difference between transcoding and encoding?
Encoding is when you take an uncompressed, raw video source and compress it. Typically this is done to create a smaller file, because it’s easier to use with more devices. Transcoding is when you take an already compressed video source, and transfer it to a different format.
What is a transcoder used for?
A video transcoder is used to convert video from one format to another. The source video can either be real-time or file-based.
Is transcoding encoding or decoding?
Transcoding is the process of taking an encoded stream and modifying some attributes— like the image size or the encoded bit rate— in a meaningful way. A transcoder receives an encoded video stream from an encoder, decodes it into a raw video again, changes it in some significant way, and re-encodes it.
What is encoder and decoder in streaming?
Essentially the opposite of live encoding, video decoding is the process of decoding or uncompressing encoded video in real-time. A video decoder converts an encoded video stream to HDMI for display on a screen or to SDI for connected to broadcast production systems including video production switchers.
What is the difference between video encoder and decoder?
Encoder circuit basically converts the applied information signal into a coded digital bit stream. Decoder performs reverse operation and recovers the original information signal from the coded bits. In case of encoder, the applied signal is the active signal input. Decoder accepts coded binary data as its input.
Is compression a transcoding?
Transcoding is taking encoded (or “compressed”) video or other digital content, decompressing it, and altering and re-compressing it. For example, a high-resolution video shot on a digital camera (HD, 4K, etc.)
What is 4K transcode?
Transsizing refers specifically to resizing the video frame, say, from a resolution of 3840×2160 (4K UHD) down to 1920×1080 (1080p) or 1280×720 (720p).

What is transcoding 4K?
Transrating refers specifically to changing bitrates, such as taking a 4K video input stream at 13 Mbps and converting it into one or more lower-bitrate streams (also known as renditions): HD at 6Mbps, or other renditions at 3 Mbps, 1.8 Mbps, 1 Mbps, 600 kbps, etc.
Is X264 CPU or GPU?
Does X264 Use Cpu? There are two ways you tell OBS to use either NVENC or AMF. If you pick AMF, it means OBS will use you graphics processing unit (GPU), or if you choose NVENC or x264, it means you will use the central processing unit (CPU).
