What is Transcoding?
In the context of video – Transcoding refers to the process of compressing video files as a lot as potential at minimal quality loss to characterize (and switch) info by using less data. Essentially, video transcoding online is the conversion of a video file from one format to a better-compressed model to make sure consumers can stream content material without buffering and at the highest potential qualities. So, how does transcoding work? And how might it affect your on a regular basis life? Keep reading to seek out out!
Image this scenario: You’ve just lately returned dwelling to your comfortable couch from your latest adventure or hobby. For the past few hours, your eyes have been locked on your pc, uploading and editing the HD movies that you captured earlier. You’ve lastly completed the editing process on your laptop computer out of your GoPro, high-quality Kodak cam, and/or Apple, Android, Windows, or other devices (Bitmovin is OS-agnostic in spite of everything!) and also you’re ready to download and share your latest creation. The raw video files that you simply recorded on your gadget are significantly larger than your standard cloud storage, file sharing service, or social media platform can (or will) handle (pro-tip: check the raw size of a video file saved on the precise gadget – likelihood is, it’s enormous!). Most raw HD video files amount to 18 GB of storage for every 60 seconds; primarily based on an average of 1920 x 1080 pixels of an ordinary RGB 3x16bit uncompressed TIFF file.
To most, clicking export after which "share to social" are the ultimate step to accumulating those sweet candy "likes." However that’s not enough for you, you need to understand how and why to move the video content from one gadget to another. The first critical step is to hit "export and save", most editing software (like the GoPro Quik for GoPro, Capture NX-D for Nikon, Seize Cam Specific for Sony devices) will ask you to specify an output folder or Network Access Storage (NAS) location (ex: a hard disk related to the wifi), a video & audio codec configuration, and a container format, like MP4. Congratulations! You’ve now accomplished the first step and unlocked all the elements required to complete the video transcode.
After you’ve confirmed the export, your pc might heat up – given the size of your newly created content material, it’s not sudden, your pc will require loads of momentary storage (in terms of gigabytes) per second of exported video. Depending on your pc’s specs the video transcode may take more or less time based in your RAM – this works inversely, decrease RAM = slower transcodes / higher RAM = faster transcodes. From the consumer perspective – transcoding is as simple as the few clicks it takes to save lots of and export to a new device. Briefly, transcoding is the process of changing one compressed (almost) losslessly video to a greater-compressed video format. This is how video compression works as it moves out of your pc to a different local device.
So, you’ve exported the video file out of your editor and also you know you have some friends or household coming over, and you wish to show off your ultimate product on your brand new high definition SmartTV. The short answer to this conundrum is to attach your gadget to the TV with an HDMI cable, but let’s be realistic, do you need to leave your comfortable sofa for such an archaic motion? Definitely not, we are in 2020 in any case! You propose on streaming your video utilizing some of the smart features on your device, however how does that work?
The editing software (like Quick for GoPro) has already created a semi-compressed file on your laptop, however chances are high that regardless of the server that your software used (GPU-based mostly with plex or an outright transcoding resolution), the file must be compressed and optimized further for streaming capabilities. This process of compressing multiple instances throughout transitions is crucial to decreasing buffering occasions and improving the person experiences as fewer resources (from the back-end) are required on your TV to decode and stream the content.
