Video Transcoding: An Essential Process for Content Distribution Across Multiple Platforms

What is Video Transcoding It refers to the process of converting a video file from one format or codec to another. This allows video files captured or encoded in one format to be played back on devices that support different formats. Transcoding is necessary because video formats have different technical specifications for things like resolution, frame rate, audio channels and compression standards. Need for Video Transcoding The need for transcoding arises because videos today need to be consumed across a wide variety of platforms like smartphones, tablets, desktops and streaming devices. However, not all devices or platforms support the same video formats. While a high-resolution movie may play fine on a high-end desktop, the same file may be too large for a mobile device with limited processing power and storage. Transcoding allows video content distributors to create optimized versions of a video tailored for specific devices or networks. Some key reasons why transcoding is required include: - Device and Platform compatibility: As mentioned earlier, different devices have varying support for video formats. Transcoding ensures the video can play on the target device. - File size optimization: Transcoding to lower resolutions and bitrates helps reduce file sizes, important for streaming over cellular networks or for devices with limited space. - Encoding optimizations: Transcoding allows re-encoding videos using optimal encoder settings, codecs and profiles best suited for the target environment. - DRM restrictions: Video Transcoding may need to be converted to formats that support Digital Rights Management (DRM) for distribution through licensing platforms. - Subtitle/Closed caption embedding: Non-burned subtitle/caption streams can be burned into the video during transcoding. Transcoding Workflow A typical video transcoding workflow would involve the following basic steps: 1. Import and Analysis: The source video file is imported into the transcoding system which then analyses key attributes like resolution, frame rate, audio/subtitle streams etc. 2. Profile Mapping: The analyzed data is mapped to pre-defined transcoding profiles configured for various target device classes or bitrate tiers. 3. Transcoding: The source file is transcoded to the appropriate target format(s), resolutions and encoding parameters as per the matched profile using CPU/GPU transcoding. 4. Optimizations: Additional optimizations may be applied like deinterlacing, denoising, ad insertion etc. 5. Quality Check: Random transcoded clips can be checked for quality issues using automated or manual review. 6. Delivery/Distribution: The transcoded files are delivered to various streaming servers, packaged for OTT/VOD platforms or downloaded directly for local playback. Transcoding Formats and Codecs Some common formats generated during transcoding include: - MP4: A popular wrapper format generated at lower resolutions for platforms like iOS, Android, Roku etc. H.264 video with AAC audio is common. - MPEG-2 Program Stream (M2PS): Used for distribution to set-top boxes and cable/satellite systems. - Flash Video (FLV/F4V): Used for progressive download and streaming delivery to desktop browsers. - Microsoft Smooth Streaming (MSS): An adaptive bitrate format optimized for Silverlight/HTML5 delivery. - HLS: A standard HTTP Live Streaming format for OTT on mobile/desktop with H.264/AAC. - DASH: An ISO-standard dynamic adaptive format popular for premium OTT with H.264/AAC or HEVC/AAC. Popular codecs used include H.264, H.265/HEVC for video compression and AAC, MP3 for audio. Selecting the right codecs and container depends on the target audience and delivery network.

I like that this gif is kinda fucked because bubbles/confetti/snow is much harder to compress efficiently.

two lonely rabbits, two hearts beating as one 🐇🖤🤍 (animated gif) now on inprnt !

old sketch from march I decided to finish <3 usually when one of my sketches (intending to become a completed drawing) gets put on the backburner, it never surfaces. I usually have to prioritize other drawings and then months or years pass and once I have time, I lose interest and start other drawings in their place... but I'm glad I mustered up the energy to finish this one, ESPECIALLY since I strongly felt I needed more gothic pieces in my gallery hehe

the relationships between characters in this series are so interesting, because there are so many character parallels. I actually had to change the personality of white alice from the sketch to the final, since I .. think I misinterpreted her story! (so I think it turned out less gothic horror than desired but you know what I'll take this <3) I first read this story when I was 14 and I 1000% BET I'll still be finding nuances and new details in the writing years into the future...

I had a lot of fun with the animation albeit just being a blink animation 😩👍 but blinks can be animated in a variety of ways! in terms of my animation skills, I do consider myself on the weaker side. so if i can integrate more animation frames into my illustrations, it'll help me become more familiar and comfortable with the medium. I especially like the difference in how many frames it takes for dark Alice vs white Alice to blink. I think the blinks came out fluidly and I'm quite satisfied with how this drawing came out!

@oddarette made me hungry with that meatsicle so I had to make a 3D render of it.

This could be the end of everything So, why don't we go somewhere only we know?

#idk why the video is so crunchy but uh enjoy

Too much spaghetti.

Not a joke, pretty sure that is the actual reason.

Video compression algorithms try to take advantage of the fact that usually most of the content of each frame is pretty close to the same content in the previous frame. Even for motion it can basically be stored as "move this section". That works pretty well when there's a few, large things moving.

But when there's a bunch of small, independently moving things, it doesn't handle that well. Snow and confetti and common examples of this, but it looks like all of Milo's bouncing spaghetti has the same effect.
