So I have hundreds of videos of ~1 minute recorded from my phone ~10 years ago, and they generally don’t have that great compression, nor they are stored in a modern and advanced video format.

For archiving purposes, I want to take advantage of my workstation’s mighty GPU to process them so that the quality is approximately the same, but the file size would be strongly reduced.

Nevertheless, compressing videos is terribly hard, and way more complex than compressing pictures, so I wouldn’t really know how to do this, what format to use, what codec, what bitrate, what parameters to keep an eye on, etc.

I don’t care if the compression takes a lot of time, I just want smaller but good looking videos.

Any tips? (Links to guides and tutorials are ok too)

Also, unfortunately I am forced to use Windows for this (don’t ask me why 🫠), but I know nothing about Windows because I hate it. Practical software suggestions are very much welcome, too!

Small thing I noticed today: splitting `.mkv` files using `ffmpeg` via the `-ss` and `-t` options works great, but the resulting `.mkv` file contains the wrong number of frames in the metadata. Evidently the total frames from the source file gets written into the metadata instead of the resulting frames post-splitting which is annoying. Not a deal breaker, but kind of annoying...easy to fix with a quick run through `mkvmerge` but still just weird.

Mam plik tekstowy oryginalnie napisany/zapisany na Windowsie XP w notatniku. Jest po polsku.

Niestety jak go teraz otwieram to mi wyskakują krzaczki gzie powinne być polskie literki, bo nie ten zestaw znaków.

Czy ktoś wie jaki zestaw znaków używał polski Windows XP w notatniku?

Hexlish Alphabet for English, Constructed Languages and Cryptography: Automatic, Structural Compression with a Phonetic Hexadecimal Alphabet

DOI : https://doi.org/10.5281/zenodo.13139469

Hexlish is a legible, sixteen-letter alphabet for writing the English language and for encoding text as legible base 16 or compressed binary. Texts composed using the alphabet are automatically compressed by exactly fifty percent when converted from Hexlish characters into binary characters. Although technically lossy, this syntactic compression enables recovery of the correct English letters via syntactic reconstruction. The implementer can predict the size of the compressed binary file and the size of the text that will result from decompression. Generally it is intuitive to recognize English alphabet analogues to Hexlish words. This makes Hexlish a legible alternative to the standard hexadecimal alphabet.

#FediHelp #WordPress #encoding
A friend told me something changed in his dreamhost co-hosted WordPress blog in 2021 and his previous posts now had encoding problems (we use lots of accented characters in Portuguese), but his current posts, after 2021 work OK.
Has anyone seen this? I'll have more information next Saturday, but I decided to ask in case it was a common, known issue...
