Dec 31, 2019 Simply put: Transcoding is critical when you want your content to reach more end users. For example, let’s say you want to do a live broadcast using a camera and encoder. You might be compressing your content with a RTMP encoder, and select the H.264 video codec at 1080p.

If you’re thinking about streaming media, you probably fall into one of two camps: Either you already know something about transcoding, or you’re wondering why you keep hearing about it. If you aren’t sure you need it, bear with me for a few paragraphs. I’ll explain what transcoding is (and isn’t), and why it might be critical for your streaming success — especially if you want to deliver adaptive streams to any device.
So, What Is Transcoding?
First, the word transcoding is commonly used as an umbrella term that covers a number of digital media tasks:
- Transcoding, at a high level, is taking already-compressed (or encoded) content; decompressing (decoding) it; and then somehow altering and recompressing it. As an example, you might change the audio and/or video format (codec) from one to another, such as converting from an MPEG2 source (commonly used in broadcast television) to H.264video and AACaudio (the most popular codecs for streaming). Other basic tasks could include adding watermarks, logos, or other graphics to your video.
- 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.
- 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).
So, when you say “transcoding,” you might be referring to any combination of the above tasks — and typically are. Video conversion is computationally intensive, so transcoding usually requires more powerful hardware resources, including faster CPUs or graphics acceleration capabilities.
What Transcoding Is Not
Transcoding should not be confused with transmuxing, which can also be referred to as repackaging, packetizing or rewrapping. Transmuxing is when you take compressed audio and video and — without changing the actual audio or video content — (re)package it into different delivery formats.
For example, you might have H.264/AAC content, and by changing the container it’s packaged in, you can deliver it as HTTP Live Streaming (HLS), Smooth Streaming, HTTP Dynamic Streaming (HDS) or Dynamic Adaptive Streaming over HTTP (DASH). The computational overhead for transmuxing is much smaller than for transcoding.
When Is Transcoding Critical?
Simply put: Transcoding is criticalwhen you want your content to reach more end users.
For example, let’s say you want to do a live broadcast using a camera and encoder. You might be compressing your content with a RTMP encoder, and select the H.264video codec at 1080p.
This needs to be delivered to online viewers. But if you attempt to stream it directly, you will have a few problems. First, viewers without sufficient bandwidth aren’t going to be able to view the stream. Their players will be buffering constantly as they wait for packets of that 1080p video to arrive. Secondly, the RTMP protocol is no longer widely supported for playback. Apple’s HLS is much more widely used. Without transcoding and transmuxing the video, you will exclude almost anyone with slower data speeds, tablets, mobile phones, and connected TV devices.
Using a transcoding software or service, you can simultaneously create a set of time-aligned video streams, each with a different bitrate and frame size, while converting the codecs and protocols to reach additional viewers. This set of internet-friendly streams can then be packaged into several adaptive streaming formats (e.g., HLS), allowing playback on almost any screen on the planet.
Another common example is broadcasting live streams using an IP camera, as would be the case with surveillance cameras and traffic cams. Again, to reach the largest number of viewers with the best possible quality allowed by their bandwidth and devices, you’d want to support adaptive streaming. You’d deliver one HD H.264/AAC stream to your transcoder (typically located on a server image in the cloud), which in turn would create multiple H.264/AAC renditions at different bitrates and resolutions. Then you’d have your media server (which might be the same server as your transcoder) package those renditions into one or more adaptive streaming formats before delivering them to end users.

Part 3. Tips to Transfer Videos from Camera to PC/Mac
With the above-listed solutions, transferring videos from your camera to PC/Mac will now be a cakewalk. To further help you with the transferring process and make it even better below listed are some useful tips.
1. The present-day camera and camcorders record high-quality videos, and thus if you transfer these videos to your PC, they occupy a lot of space on your PC's hard drive. Therefore, to save your computer hard disk space, you can either save the videos to an external drive or burn them to DVD.
2. Different types of cameras and camcorders use different types of connection. Thus it is advisable to check the manual to know the type of connection needed before you transfer the videos from Handycam to PC. Also, check the camera for the available ports.
3. It is important to check if your PC has the needed ports to transfer videos from the camera. Their compatibility with the camera also needs to be checked before the camcorder PC transfer process.
4. While you capture video from camcorder to PC on Windows 7 or other systems, it is always better to close the other programs which are running on your PC as the transfer process uses a lot of system resources.
