What's the most niche topic that you can confidently talk about for 5 minutes?

Video transcoding. But I couldn't keep it to only five minutes. So, for everyone's safety, never ask me.

Seriously, I have *forgotten* more about video transcoding than most anyone would ever want to know. And certainly would ever want to hear at an *excruciating* length that which I still remember. Do not poke the she-bear. šŸ˜‚

@lisamelton What really is transcoding anyway? I see it mentioned all the time in media server threads but the best I can figure out is that it makes whatever jumble of formats you have play the same or work on whatever devices?

@DarkAthena Transcoding video and/or audio is typically done to make that media smaller and/or more portable. Usually while remaining high enough quality to be mistaken for the originals.

I sometimes do this for my my collection of Blu-ray Discs and DVDs.

However, professional media studios do this all the time as well. For example, Netflix transcodes all the movies and TV shows you watch into many different distribution formats.

Does that answer your question?

@lisamelton Ooooooh, yes! So when I rip my DVDs into a different format, I’m transcoding?
in reply to DarkAthena šŸ

@DarkAthena Technically, no. Ripping is not transcoding.

Ripping typically means that the underlying video and audio formats are unchanged. Ripping just changes the container which holds them.

Ripping can often solve *some* portability problems, but not all of them.

To put it another way, ripping is a lossless change in format while transcoding is "lossy," i.e. information is lost in that process.

Does that make sense?

maybe TTRPG Game Design / Mechanics, but like @lisamelton it'd be hard to keep it to only 5 minutes.

@masukomi That reminds me, don't ever get me started about gamedev or you and I may just end civilization as we know it.
