Tumblr video format guide

a.k.a. How to make a video I downloaded from TikTok/Twitter not to look like crap here.

So, this is something I learned the hard way, and I decided to share it with you all. Especially videos from TikTok look awful here if you don't re-encode them.

There's this Tumblr help page about posting videos that says

Well, I downloaded Handbrake and these are the presets you'll see

You most definitely don't want to use General -> HQ 720p30 Surround, because it adds two audio tracks, and I'm not sure if it's even Tumblr compatible. Fast or Very Fast 720p30 should be ok to use.

If you're using other video editors/tools, the main point seems to be that you are using

H264 encoder with Main profile (or Baseline profile if you want to play safe) and level = 3.1

MP4 file/container

FPS, audio format and video resolution don't seem to matter so much but probably better to use recommended/most used values/formats, i.e.

FPS = 30

Audio format = AAC LC

Video resolution = 720p (but avoid upscaling). 720p is the best for videos downloaded from TikTok/Twitter, but if you're uploading your own videos with good picture quality and bitrates, 1080p should be fine also.

In my (still ongoing) adventure to re-encode all the videos on my Jellyfin server to AV1 in order to save space, I’d like to present you all with the biggest success I’ve had yet:

A 19.06GB folder has been condensed to 9.2GB. 10 whole gigabytes saved by just getting my computer toasty for a few days. Absolutely amazing.

And we still have over 100 GB to go.

So I've been experimenting with current-gen video codecs to try and replace x264 in my current workflow. I recorded a bunch of lossless test clips that contain various challenging things for video encoding; grain, concentric lines, red text, etc… and have been doing various re-encodes of these and recording the metrics.

Here's a status report I DM'd my friend, because someone here might find it interesting/useful. Also it's a VP8 WebP because it's funny and Tumblr doesn't support HEIC or AVIF.

HandBrake

HandBrake is a free, open-source tool designed for converting video files from virtually any format into a selection of modern, widely compatible codecs. It makes it easy to prepare video files from your camera for playback on a variety of devices, such as iPhones, iPods, Apple TVs, Android phones, Android tablets, and more. The app also fully supports one of the most popular video conversion…

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.

-c:v libx264 -crf 20 gives me what I like.

how does it map to h264_amf? I don't see constant rate factor in the options...

I suddenly had the urge to make a Dark Sonic edit.

Can this guy be cool again? He genuinely has potential in character exploration for Sonic.

I downloaded an entire 20-Season series via a torrent. The torrent came in around 160+ GB. After re-encoding everything as AV1 via Shutter Encoder, it's currently on path to being around 55 GB when it's complete.

This shit's crazy. I wish torrent makers would utilize modern codecs and file types before seeding them. It'd sure save a lot of bandwidth, data, and time downloading 7zips and AV1 media, rather than ZIP and H.264/5 media. And, like, given that 7zip is open-source and VLC supports AV1, and both are free and open-source, there's literally no excuse.
