What is Transcoding?
Within the context of video – Transcoding refers back to the process of compressing video files as much as attainable at minimal quality loss to characterize (and transfer) data by utilizing less data. Essentially, video transcoding on-line is the conversion of a video file from one format to a better-compressed model to make sure consumers can stream content without buffering and at the highest possible qualities. So, how does transcoding work? And the way may it have an effect on your everyday life? Keep reading to seek out out!
Image this state of affairs: You’ve just lately returned dwelling to your comfortable couch from your latest adventure or hobby. For the previous few hours, your eyes have been locked in your computer, uploading and editing the HD videos that you simply captured earlier. You’ve finally finished the editing process in your laptop computer out of your GoPro, high-quality Kodak cam, and/or Apple, Android, Windows, or other gadgets (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 bigger than your standard cloud storage, file sharing service, or social media platform can (or will) deal with (pro-tip: check the raw size of a video file saved on the precise device – chances are high, it’s big!). 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 a typical RGB 3x16bit uncompressed TIFF file.
To most, clicking export after which "share to social" are the final step to collecting these candy sweet "likes." But 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, Seize NX-D for Nikon, Capture Cam Categorical for Sony units) 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 completed step one and unlocked all the elements required to complete the video transcode.
After you’ve confirmed the export, your computer might heat up – given the size of your newly created content, it’s not surprising, your pc will require lots of momentary storage (in terms of gigabytes) per second of exported video. Relying in your computer’s specifications the video transcode might take more or less time based mostly on your RAM – this works inversely, decrease RAM = slower transcodes / higher RAM = faster transcodes. From the consumer perspective – transcoding is as easy as the few clicks it takes to save lots of and export to a new device. In brief, transcoding is the process of changing one compressed (nearly) losslessly video to a better-compressed video format. This is how video compression works as it moves out of your laptop to another local device.
So, you’ve exported the video file out of your editor and also you know you may have some friends or family coming over, and you want to show off your ultimate product in your brand new high definition SmartTV. The brief answer to this conundrum is to attach your machine to the TV with an HDMI cable, however let’s be realistic, do you wish to go away your comfortable sofa for such an archaic action? Definitely not, we are in 2020 in spite of everything! You plan on streaming your video utilizing a number of the smart options on your gadget, but how does that work?
The editing software (like Quick for GoPro) has already created a semi-compressed file on your pc, but chances are high that regardless of the server that your software used (GPU-based mostly with plex or an outright transcoding answer), the file must be compressed and optimized additional for streaming capabilities. This process of compressing multiple instances throughout transitions is imperative to decreasing buffering times and improving the person experiences as fewer resources (from the back-end) are required in your TV to decode and stream the content.
