The process of creating multiple versions of the same video is named as Video Transcoding. Each version is optimized for various types of devices used for watching videos. Video Transcoding process allows the broadcasters to deliver high-quality videos to users with high-speed internet and avoids buffering at low internet speed. It is a helpful tool for media delivery without any loss of quality and time-consuming process. Here are the best practices to achieve high-quality video.
Video Transcoding best practices to achieve High Quality in Videos:
Encode from the best quality source:
If the source of the video is interlaced, try to enforce and de-interlace settings to achieve high-quality video.
Use 2-Pass VBR:
Unlike Constant Bit Rate and Variable Bit Rate methods, the 2-pass VBR method is the best method to transcode video to achieve the best picture quality.
Try to use the median filters to improve the picture quality in your video by correcting the defects.
Mobile Device Specific Settings:
If you are using it for mobile devices, make sure to change the platform-specific settings.
Create adaptive sets:
First should verify that the video playback is running with no issues and also overall connection speeds. Create adaptive sets that transcodes the same video with multiple bitrates.
Select the right bitrates for encoding and transcoding of any video. Sometimes selecting the right bitrate depends on the video type.
Width and Height:
Video Transcoding delivers high-quality video when the width and height are in the right use. People can use any width or height, but be careful with non-optimal settings damage the quality and it may reduce the frame rates.
Consider Turbo Mode:
Considering the right Turbo Mode will improve 2x-4x speed gains over normal mode, increase your costs $1-$2/GB. You can enable the turbo mode with a simple call.
Choose the right streaming content and All the content that is viewed on the internet inside an application is considered streaming content.
Eliminate Blocking Artifacts:
Blocking artifacts are undesirable video characteristics that appear to be made up of small squares, rather than smooth edges. Reduce the blocking artifacts to improve H.264 encoding efficiency and it’s best for horizontal and vertical frame size dimensions.
Pay Attention to your Profile Settings:
Pay attention to your profile settings. If your screen dimensions are LD chose baseline and dimensions are SD choose mainframe dimensions SD (720) chose high.
Progressive Scan Mode for Source Video:
Use the progressive scan modes of professional cameras, smartphones that offer a progressive capture mode.
Providing a high-quality source video is critical and your output will be good if you give the right input. The garbage-in garbage-out options apply here.
Optimize your profiles:
Optimize your profiles such as MP4 H.264/AVC for delivery codec and also for modern video applications.
Frame Rate (FPS):
The Frame rates are the frequency at which separate frames are displayed. That is expressed in frames per second. 23.98, 24, 25, 29.97, 30, 50, 59.94, and 60 are the main standards for Video and television.
Balancing between Bitrate and Resolution:
It is still a challenging task to maintain the right balance between bitrate and resolution as it is related to an end user’s system capability and connection speed.
Maintain proper bandwidth that is faster than ever or which is equal t0 10 Mbps spread for the high-quality picture. Connection speed is one element that might impact a user’s streaming experience.
The network is one more parameter in video transcoding average users will connect to the internet via home WIFI or company network. Connecting to the home network may affect the overall bandwidth and video quality.
Different users use different devices as each device has its own potentials. So, make sure to get into specific device settings for lossless video.
The device’s age plays a key role in streaming content. The old versions of devices may not have supportive memory, OS to handle HD quality video streaming.
Few browsers have streaming problems while adopting the HTML5 and MPEG DASH delivery. The browser also just needs to be updated for delivering the HD quality video content.
Choose the best platform for video Transcoding and to get lossless video delivery. Transcoding plays a major role in the estimating process of power and other platform parameters.
Setting the performance bar:
Setting the performance bar at the high end of the STB platform and it must be set for HDTV 1080p. STBs are capable of supporting this high level of rescaling display outputs and throughput in real-time.
Try to close all other unused apps in the window for fast and reliable video delivery.
Video Transcoding is important when you want your videos to reach huge end-users across various devices. Choosing the right transcoding solution or platforms to ensure good user experience. Here we have gone through some best practices that cover a simple pipeline for transcoding high-quality videos for web delivery.
