Continuous development phase
January 2025
01/1: Fixed a bug causing a site database crash after some time.
October 2024
10/8: An improved size-seeking algorithm delivers pixel-accurate GIF resolution without requiring more attempts than the previous algorithm. This boosts GIF quality by up to 20%.
September 2024
09/25: Fixed an issue causing filesize accuracy to be poor on longer videos, especially MP4.
09/18: Configured YT-DLP to limit the length of titles in file names to 64, which prevents errors related to the filename being too long. This especially affected tweets, where YT-DLP considers the tweet's content to be the title.
09/12: Fixed a bug causing an infinite loop on the transcode server when compressing a video with greater than double framerate to a low bitrate.
09/11: Logged-in users must now have their email addresses verified in order to compress media. In addition, users can now change or reset their passwords in the My Account page. Further improvements to account management are upcoming. Additionally, fixed a bug that may have caused some accounts to not have their CPU minutes regenerated monthly.
August 2024
08/15: Version 0.3 is released with numerous improvements to video processing. Check the Discord server for a full description.
08/12: The v0.3 refactor is now also being piloted for AV1/Opus MKV/WebM video encoding. Report any issues with it on the Discord. Coming soon to MP4 mode, completing v0.3.
08/04: The v0.3 refactor is being piloted for VP9/Opus WebM video encoding. Report any issues with it on the Discord.
July 2024
07/30: The v0.3 refactor is complete for the audio-only encoding pipeline. Also, Twitter links work now.
07/29: Fixed some websites failing to download using YT-DLP.
April 2024
04/26: A new architecture for logins offers a seamless experience, better security, and no more having to log in every 24 hours. The premium ad free experience is now delivered through the same URL as the normal page instead of through /ad-free/page, dynamically set on the server side.
04/24: Sticker compression now accepts video inputs and still stickers use a trick to display losslessly on Discord. Thanks to Kae for the suggestion.
November 2023
11/23: Added an option to download audio only when using the URL mode.
11/4: Our AV1 video embedding tool now works on X, the platform formerly known as Twitter, just like x266.mov's embedding tool.
11/3: You can now choose to mux AV1 into WebM instead of MKV so you can use it with our newly revamped
AV1 embed hack.
11/3: SVT-AV1 is now used for the Fastest and Fast presets as the SVT team has improved the VBR. This makes AV1 encodes much faster.
October 2023
10/4: Sticker encoding will now cut any inputs to 1 frame less than 5 seconds (what Discord wants), rather than rejecting >5s inputs
September 2023
09/19: Added MP3 encoding, plus a bunch of other changes that I didn't log
August 2023
08/07: Added WebP thumbnails, allowing alpha in thumbnails
July 2023
07/10: Added HTTP/2
07/08: Added Brotli encoding for static assets, as well as Zopfli 1000 iterations for clients that don't support Brotli compression. The HTML document is not a static asset.
07/06: Fixed an issue where Twitter links silently errored because of the elongated muskrat (it now loudly errors)
07/01: Fixed a serious bug where some videos would error with "Unknown error on first pass" with MP4 encoding.
June 2023
06/23: Remade the UI icons in SVG format: transferred size with
no ads is now down to 111.16 KB
06/15: Improved output file naming: sizes less than 1MiB are now named in kilobytes, or "emote"/"sticker" if the special pathway was activated
06/14: Improved page metrics by deferring the loading of jQuery until after the page loads
06/12: Added WebP icons, even the ones that change, to save you 4-5 kB in bandwidth (it wasn't worth my time at all)
06/11: WE GOT APPROVED FOR ADSENSE!
06/10: Fixed a bug that caused uploads to be interrupted on the hour
06/07: Fixed a bug that gave users the wrong amount of transferred MB
May 2023
05/30: Added an option to remember your target size
05/08: Made the changelog suck less, i.e. blatantly ripped off how 8mb.video displays the changelog
05/07: Started work on site improvements: changes to navbar, dropping the .html from URLs, etc.
05/04: Overhauled the
AV1 embedder. It's no longer ugly HTML.
April 2023
04/27: Changed the default output size to 25MB due to Discord's file size limit change.
04/13: Added Ultra and Extreme modes for PNG/JPEG encoding, which use SSIMULACRA2 to guarantee the highest JPEG quality possible.
04/11: Added Animated AVIF, which offers over an order of magnitude better efficiency than GIF. It even works with alpha.
04/10: You can now create a free Autocompressor account, log into it, and see its statistics.
04/04: Figured out how to track CPU minutes. You aren't limited in your use of them yet... and it turns out that a CPU minute is a lot more than I thought it was.
04/03: Images are now stripped of Exif and color profiles, and converted to sRGB. Therefore, compressing "HDR" PNG files will now work properly.
04/03: Figured out how to do authentication and allow higher tier users to do more things. That doesn't mean you can actually login/register yourself yet, but it's backend progress.
04/02: Deactivated the April Fool's day joke where all files are compressed to 1MB larger than you asked for
March 2023
03/30: Backend is now capable of tracking unregistered users and active jobs. This allows us to bill accounts for CPU minutes and bandwidth in the future.
03/14: You can now link videos that are downloadable by YT-DLP. For now, they must be less than 2GB and less than an hour.
03/14: Improved VP9 and AV1 fast presets
03/13: Added link option. DIRECT LINKS TO FILES ONLY right now, yt-dlp comes later, perhaps even today.
Known issues: Uploads seem a little slow. We'll be trying to figure that out.
Transcodes will be up to 3 times faster, and large images can be handled more easily.
03/10: RELEASE 0.2! :woag: We now have a faster server.
03/02: Added a video thumbnail feature (interface is bad but it exists)
February 2023
02/28: Overshoot retrys caused by video will no longer harm audio quality and vice versa
02/24: Fixed AWebP to use the new faster Q-seeking algorithm
02/23: No more losing your progress on a transcode! Each job has its own URL now, so you can just go back
02/23: Fixed an issue where "bitrate too low for the selected codec" didn't show up
02/19: Huge speed and filesize accuracy improvements for all image encoding
02/17: PROGRESS REPORTING!!!! for video encoding
02/16: New, better looking UI
02/16: Join our Discord server!
02/14: Proper support for animated and still Discord emote and sticker encoding
02/05: Added AVIF still image encoding for up to 50% better efficiency than JPEG
02/04: JPEG/PNG encoding is now WAY faster and has presets
January 2023
01/30: Adjusted WebP encoding based on
new science
01/20: Added Smart Audio Adjustment (see
about page)
01/08: Added AV1
01/08: Fixed a mathematical error causing too high res to be selected in fast presets
01/05: Finally figured out how i broke autocompressor :facepalm:
