My Little Pocket Universe
Tricks and tips I’ve picked up for editing and/or processing video files.
I wanted to stream one of my Ubiquiti cameras without exposing the rtsps stream directly to the internet. They do offer a “public” URL option directly with the camera, but that is limited to one stream/watcher at a time, which is fine for a one-off or very specific scenario. But I wanted to be able … Read more
This page is going to be random notes and discoveries about my new Insta360 Pro 2 VR camera. The camera is impressive. The documentation, not so much. I will likely take sections of this stream of conscience and make them into their own pages once I have enough information. The camera runs Linux for Tegra … Read more
So you have an Apple Vision Pro, or its little cousin the Oculus Quest and you want to use the spatial movie format. This is not a new format, it has been around since 2014, but Apple is the first to start using it prominently. Sure, there is whatever they put on Disney+, or the … Read more
Sometimes you come across a poorly created video file where the audio and the video are slightly out of sync with each other. Rather than using a big powerful video editing package, you can use ffmpeg to adjust the times without re-encoding. The key is the itsoffset option. The ffmpeg command line is almost a … Read more
Firstly; this is information on how to extract your legally bought copy of 3D movies so you can play them on devices that do not use optical media (e.g. a VR headset). I do not condone piracy. Whether you want to make a backup, or to convert it to a more usable format, 3D movies … Read more
I am not advocating piracy here. This is just a method to remove the purchased flag from Apple Music/iTunes downloaded files, and make them show up as normal AAC files if you have some reason to do so. The shotgun approach is to just remove all the meta-data from the stream. This is simple enough … Read more
So you’ve bought that shiny 3D Blu-Ray, but they don’t make 3D TVs anymore. Now you have that shiny new VR headset, which just screams “Let me play my 3D movies!,” but alas, no such luck. Well, here is how to extract your purchased Blu-Rays (only use these instructions with movies you own, please!). You … Read more
When archiving videos, often times there is a logo of some sort that really distracts. Or even worse, is put in by someone who had nothing to do with actually making the video like they are taking credit for the hard work of the production company. I ran into a case of the latter, and … Read more
When I am converting videos from one format to another, I often need to convert the susbtitles as well. I wrote a script to extract (and convert PGS to VobSub). This is a bash script that I am running on my Mac. If you want to run it on linux, just update the PATHs to … Read more
Subtitles come in a myriad of formats, and not all of them work in every container format, and not all containers are as easy to work with. Converting Matroska (mkv) files to MP4s cause issues when the mkv has PGS (Blu-Ray) subtitles. PGS subtitles can be embedded in Matroska video files, but not MP4s. But … Read more
