When I thought you were transferring monochrome videos, even though I know nothing about tech, I instantly thought of a good type of video to make into 3-bit terminal text video: black-and-white cartoons from the early movie days. Like the 30s Looney Tunes and Popeye cartoons. They were made with less than ideal optics in mind and generally had great contrasts throughout. Also, you would likely find a public domain cartoon and thus just put the entire video on KZbin with audio. No demonitization nonsense to deal with.

I wrote a C++ program to play full color video in the console, compatible with both Windows and Linux. Demo here: kzbin.info/www/bejne/qpbLeHSYh6dgqdk On Linux it is actually much faster, even through SSH in Windows Subsystem for Linux, because the ANSI escape codes work much faster than Windows color change commands. I only change ASCII color for contiguous stripes of the same color. For the video I also use the trick to compare the new ASCII frame with the last, and only draw the pixel (stripes) that have changed between frames by jumping the cursor around.

“Compression?” -Modern Game Developer

Windows 3.x had 32 bit extensions for using features of the 386 and 486 processors, long before Windows 95 came around, despite the fact that it all ran on top of the ostensibly 16 bit MS DOS. There have also been several 32 bit versions of 'DOS' created over the years, which are broadly compatible with MS DOS. But that would probably be cheating. 😉

That's how many programs circa 1995 were compatible with both Windows 3.1 and Windows 95. But since Windows 95 could run most Windows 3.1 software, many programs were just straight 16 bit but written to not run into any incompatibilities in Win 95. A problem with software written to work with Win32s is it will often run on 64 bit versions of Windows, but cannot be installed because the installer is 16 bit. Some programs can be extracted from their install files, dumped into a folder and work. Others that doesn't work for. The fix there is either to build a new 32 bit installer or use one of the open source ports of NTVDM to x64 to run 16 bit software in 64 bit Windows.

[@Nunya58294]

[@engineering_georg8122]

Could the compression be improved by looking at several frames at once? A "pixel" of a color should more or less stay the same in the next frame. (This would be the temporal equivalent to the spatial predictive coding you used ;D -- maybe it saves even more space)

[@HappyBeezerStudios]

Thought the same. Many video codecs do that to reduce file size. With only a handful of characters instead of 16 million colors that should be quite compact.

[@achtsekundenfurz7876]

Also, much of the compression trouble comes from the "noise" introduced by dithering. Maybe you could store the raw data in 4 to 5 bit values (16 or 32 colors, roughtly one to 4 levels between the 7 exact values that lead to a solid "color" i.e. one character repeated over and over). That's more data but might compress just as well or even slightly better. Even more so if you only encode the differences to the last frame, and one "index" per frame (or maybe per block of 20x5 characters, since sometimes, there's a lot of static background behind the moving parts of the scene). The index could point to one of eight decoding tables, from #7 for a frame that's virtually unchanged where the "+0" value compresses very well, all the way down to table #0, which compresses only marginally but doesn't include a lot of overhead either if the values are completely different (maybe even make #0 mean "don't decode at all, just overwrite with those raw values." That #0 would come in handy after a hard cut, where there's no relation to the previous frame, or the first frame ever, which can't compare to any previous frame at all. That would impose the burden of dithering on the playback software, but that should be almost as easy as Huffman decoding.

[@lordsiomai]

Sounds like mp4 with their i frames and p frames. Good idea!

[@dh2032]

yes only redrawing what's changed, look at what accomplished there a lot ...... ,,,, xxxxx, in large patches on the screen, ?

[@rich1051414]

It gets complicated, since you would then need to also keep track of pixel locations across frames, or increase the bit depth enough to be able to include a skip pixel length, which would bloat the overall frame overhead either way. It gets easier if you combine with zip compression. You can represent all pixels that don't change with the same value, and the zip compression will do the work squashing all the redundancies.

[@FinFET]

Bet the next one will be "oops i did it again" 👀 Great video!

[@Stego27]

I went down the colour route a while back and two things that greatly improved the quality were: - Using the lower half block character (▄) and setting foreground and background colour to double vertical resolution. - Using the rgb ANSI codes for full RGB playback. Not very compressible i'm sure...

[@Roxor128]

Another way to increase "graphical" resolution in text-mode if you don't mind a bit of x86 assembler and not being portable: Use the 160*100 CGA text-mode hack. It sets the card to 80*25 text mode but tells the CGA card to use characters only 2 pixels tall and uses the horizontal half-block character and background/foreground colours to create makeshift pixels, giving a pseudo-graphics mode that can have all 16 CGA colours on screen at once (the actual graphics modes only allow 2 or 4 colours).

[@HappyBeezerStudios]

That should work under direct DOS, but I doubt that would run that nicely in the windowed command line on a more recent system.

[@wesleymays1931]

At this point you're compressing a plain old video, just chunked down a bit. It's a lot harder, but still doable.

[@wesleymays1931]

I mean, if the video's short enough, you could use something like the PL_MPEG decoder. Or roll your own format if you want longer videos.

[@klimisioannidis]

What about PPMd compression, have you considered it?

[@MK-lk7nc]

image to text conversion was something I got really into in IRC days years ago, making fullest use of the IRC color formating was it's own fine art. One suggestion I could make is to take each cell of graphical pixels you're encoding as text, and further analyzing them to determine which ascii character most closely matches the flow of contrast within that cell. So if it's a vertical line, the algo wants to use a vertical pipe to display it, even if the brightness isn't as close, etc. This is something I always wanted to try but never got motivated enough to actually do - maybe you're the one. An impressive display of ascii Britney here, nice job. Lately I've been working on a music visualizer in Unity, some clips on my channel - maybe that would be a fun ascii project, since then there's no need ot store any video at all, just procedurally generate it off the musical input.

[@MZZenyl]

- There actually are ANSI escape sequences for full 24-bit RGB colors (the standard 16,777,216 different colors): "[38;2;RRR;GGG;BBBm" for foreground and "[48;2;RRR;GGG;BBBm" for background, with RRR, GGG, and BBB being the decimal color channel values (0-255). On Windows, if using ConHost (the "old" default console host application, as opposite to the new Windows Terminal UWP application), this is only supported as of Windows 10 (from around 2017 and going forward). - I've managed to get a 120x30 console buffer to update, with fully randomized RGB fore- and background colors for each character, around 60-100 times per second. The "framerate" with ConHost is tied to your CPU, with mine being a quadcore i5 from 2014. This was written in C#, however utilized P/Invoke to go around .NET's relatively slow "Console.Write" method, and instead utilize WinAPI's "WriteConsole" function, which dramatically increases performance.

[@hojnikb]

There's something else that could be done and would yield an actual video clip on floppy disk. If we just limit ourself to floppy disk, but not floppy drives, you can actually fit 32MB onto a regular floppy media. What you need is a SuperDisk LS-240 drive, which has the ability to format and store regular floppy to 32MB, instead of the usual 1,44MB. So data is on the floppy media, it's just not compatabile with anything other than LS-240. Now that we have 32MB to play with, we need to store the video as efficiently as possible. VVC (or H.266) is the latest and most efficient codec out there. With toxic being a 3.31min video, we have about ~1200Kbit to play with. I think 1080p@30FPS would yield a pretty decent result.

[@loganiushere]

I bet you could get 30FPS video working using some kind of temporal compression. My ideas is if most or the frame stays the same from the last frame, use some kind of RLE to compress the regions of the frame that stay the same, then use the compression you designed to encode the rest. Incidentally, I think you nearly reinvented LZMA. Come to think of it, LZMA might actually be just what you need, especially because the LZ77 component will efficiently encode any repeated data, such as data seen on a previous frame.

[@achtsekundenfurz7876]

One issue is that you never know how those character look on the target platform. For example, * could be perfectly centered on some low-res platforms like C64 and IBM CGA.

I think a better possible compression could've been something along these lines (using PNG compression as an inspiration): for each pixel select the closest match between the one above, left or temporally before, temporally before + left/right/up/down; but with some well chosen bias to make direction-difference pairs more similar on average. Store the direction-difference pairs for everything (except the first top left pixel) via Huffman coding You could get even better compression by modelling brightness as just a ring modulo [number of brightness levels] so that you can just wrap around from the highest to lowest with a low number, increasing compression rate for high contrast areas as well

Sounds like a paradox to demonstrate the ability of store video into a 1980s media when no 1980s computer would have the processing power to play it. LoL.

It was pretty hard getting boku no pico first OVA fit into 8 MB (discord free file limit), the actual hardest part for me was audio, while video can go quite potato mode, the audio still takes up quite a lot space.

5:14 I’ve seen Rickroll so many times that I swear I could see the colors of his hair and skin….that is such a weird illusion

[@CharlesVanNoland]

Another idea, for maximizing detail is to stretch the contrast of each frame. Find the min/max pixel values and renormalize the rest of them to that range. You can also lerp between the original frame and the contrast-stretched frame.

Your short had sound. Was that movie magic?

[@thedudely1]

I love representing formats like pictures or video in weird ways like through sound or text or whatever else.

Check out 8088 Corruption by Trixter/Hornet (kzbin.info/www/bejne/eZTFqp2Nn92lla8 (download link in the description)). Text-mode full-motion video on an XT with CGA and a Sound Blaster. He later followed it up with 8088 Domination, which does the same thing in graphics mode. If you want to run them on a real period machine (as opposed to an emulator), you will need an entire hard drive for just one of them as they're 10 and 30 MB, respectively.

Consider using the BWT before RLE to get a potential further space saving

[@HappyBeezerStudios]

I guess the 30 to 15 fps step doesn't inform any temporal information? That could reduce the filesize even more. Just how the compression works with the likelihood that a specific character is next to another, the same could be done for following frames. No improvement for scene changes, but within a scene that should help getting the size further down.

[@stephenkamenar]

a color h256 video takes up less space than your compressed 7 characters ascii grayscale terminal video? that's insane

[@BBVE1]

I remember the ASCII star wars movie, but that was streamed though telnet so it focused on smaller bandwith rather than capacity, similar idea though

[@HappyBeezerStudios]

It is still available. Remembered it last week and had to check it out again. That also goes more for a cartoon lineart style instead of translating video into text. If only I'd finally get network working under DOS.

[@warlockpaladin2261]

I would like to see this.

[@SquirrelMonkeyCom]

You should make a video about the Sloot Digital Coding System.

[@Meshamu]

I don't know of any floppy drives that would allow for it, but if there were one that could put an arbitrary signal onto a floppy, and read that signal back into the computer, instead of the usual data patterns, how much low-res analog video could you cram onto one? I guess Sony figured it out already with the old analog Mavicas, but I haven't found the info on how many images they crammed onto a disk.
