Cloud Transcoding: Concept and Why It Is Promising

Brief Introduction of Cloud Transcoding

Cloud transcoding is one of the most popular workflows in video production and delivery over the past few years. For people who surf the internet regularly, the word "cloud" should be more familiar to them because many of them have used various of cloud services like could storage, cloud computing, etc. To put the word specific, cloud refers to the internet, and cloud service is the service that functioned on a server and you can use it online. Transcoding is the process of converting video content into different format, resolution, bitrate, etc. Obviously, the concept "cloud transcoding" means doing your transcoding tasks on an internet or virtualized server (or we can say "in the cloud").

Why We Need Cloud Transcoding?

As modern devices become rather diverse, e.g., mobile phones, tablets, laptops, desktops, TVs, compatibility has become a very critical point for media service providers. For example, video that encoded in H.264 is very common in many areas, while some audiences only have set-top boxes that support video format in MPEG-2. To make the content still accessible for these audiences, service providers should transcode their H.264 video into MPEG-2 format. Besides, when it comes to transmission, bandwidth is one of the most important factors to be considered. To increase the effectiveness of the transmission network, a practical way is to convert the video into other high-efficiency coding format (e.g., from H.264 to H.265) and therefore more content can be delivered using limited bandwidth. This is just what transcoding can do for you.

Some people may argue that we understand the importance of transcoding, but why not on-premise transcoding? Although siloed transcoding systems may be suitable under some circumstances, cloud transcoding usually surpasses the traditional method in several aspects:

Marvellous Video Quality
There is no need to worry about the video quality when using cloud transcoding service. Cloud-based service is as powerful as the traditional on-premise system and realize the advantages of cloud transcoding will not at the cost of diminishing video quality.
Superb Flexibility
It is somewhat cumbersome to use on-premise hardware for transcoding. With a cloud transcoding service, you can get access to it anywhere with a device (e.g., mobile phone, laptop) that has internet connection. This can be very convenient if you want to do your production remotely and near the broadcasting site.
High Cost-effectiveness
Using cloud transcoding service means you do not need toprepare extra space for transcoding in your server room. This can help you savegreat amount of investment in hardware, shelf, electricity, maintenance, etc.
Excellent Scalability
As an intrinsic featureof cloud service, you can customize your configuration anywhere and anytime youwant, which means the could transcoding service has great potential forextension. You can easily scale up or down according to your requirements, andtherefore you do not need to worry about hardware overload or redundancy ifyour transcoding planning is changed regularly.

Things to Know When Choosing a Cloud Transcoding Service

To ensure you have the best experience when using cloud transcoding services, you should ponder the following things before you use it:
Quantify Your Requirement
You need a specific and quantitative planning for yourtranscoding tasks. For example, you need to decide the amount of video files orchannels you want to transcode and calculate the total bandwidth requirement inthe transcoding process. Besides, you need to decide your input and outputformats (e.g., HEVC, AVC, MPEG-2), and know better about the format that thecloud transcoding platform supports.
Understand the Pricing
You should know how the service charge you so that you canmake a smart budget. There are various of pricing model in the market, they maycharge you based on time, bandwidth, volume of tasks, etc. Moreover, you shouldfind out whether they charge for extra service like streaming.
Ask for a Trial
It is necessary to ask for a trial before you pay for theservice. This can help you test the stability of the transcoding system, getfamiliar to the functions and understand the discrepancies between yourrequirements and their functions.
Leverage the Existing System
Mostly, using cloud transcoding service do not mean abandon the existing transcoding system, which may be hardware-based. One way to make full use of the former system is to use it as your backup system for the cloud-based system, this can make your transcoding process more stable and reliable. Another way is to leave part of function on your former system and make it work simultaneously with the cloud system. However, you should pay attention to the compatibility between the systems when you using them.

Sumavision has prepared a versatile andpowerful cloud-based transcoding service to help you easily convert your videointo target format and resolution. Apart from basic transcoding function,others like streaming and gateway functions are also integrated into the systemas modules to enable a simpler workflow and improve efficiency.
