Hi, yes it's a good idea, thanks for the feedback.
@Luke: You guys need a few new standard responses in the drop-down list... lol
That's a huge and complex task to get it right and the current Emby conversion feature is not the best choice when your intention is to replace your original files. It is fine to create additional versions with reduced quality, but to actually replace content - a process where you don't want to loose quality but also not blow up the video size - it isn't suited well.
My recommendation would be to leave your content unchanged, and (manually) convert only those videos where you are experiencing playback problems.
I really see your point here... however, I have 50TB+ of series episode where the average episode is 4GB+. I'm perfectly happy to lose a little quality for most of these, as it's not very likely these series will be watched over and over again... I'm not a professional streaming provider (though sometimes it feels like it with the amount of time I'm spending on this... lol). Either way, I don't have 4k content and an episode of 1080p content is usually very watchable in x265 HEVC on 8MBps and AAC, which will give me filesize of abut 2GB, especially since most of my users use a tablet like device or even a mobile phone to consume most of their content...
Also, you can never 100% trust that all conversion results will be OK, so I wouldn't let the original videos be replaced (deleted) automatically. That would mean that you need more storage space instead of less.
Generally, saving space is a rather bad motivation for converting content. Every conversion reduces quality, and when a converted video is going to be played it may still need to be transcoded by Emby. "Older" codecs may take more space, but they also require less processing power (for the decoding side) when Emby transcodes them.
I wouldn't let it replace automatically, but would check stuff at least watch a few seconds, scroll through and check the length of the episode against the original before deleting the original. Since it takes ages for a conversion to complete (it's not more than about 20 per day if very lucky), it doesn't take a lot of time to check this...
I agree with the decoding/transcoding statement. I have a lot of .avi files from the 90s though. Somehow these always give issues, not matter on which device these are being played. It's either no sound or no image or distorted images with green blocks through the stream for some strange reason, etc. which mostly disappear when converted to h264/h265 and I didn't really notice any difference in quality...
That's a huge and complex task to get it right and the current Emby conversion feature is not the best choice when your intention is to replace your original files.
Yes, it will take anything upwards of a year or two, but I have time and the patience to do it. Afterall I did correct the metadata of about 2 million music tracks and close to 200k ebooks and 15TB worth of comics. I've been at this for close to 15 years. Any recommendations for a good piece of software that could do this properly if not Emby, though?
Finally: I had thought about a feature like that before, but I had considered it more as a "professional" feature for a special edition or a separate product.
Since it doesn't seem Emby wants to go the path of Prof/Spec editions (yet), I doubt that would materialize any time soon... (I'm still waiting for a proper MySQL/MSSQL backend so that there isn't so much of a performance hit once you hit 200k+ items on the server. It's a real problem for me, but I won't hold my breath and will keep on using various other server products) When it comes to a separate product, well, I'd love to test...
