Optimize media

It would be nice if there were an option to optimize media with a single click (or select an option to optimize a library or a folder). Optimization would transcode the existing media into the most efficient format (whatever Emby considers most efficient, such as H.264 or H.265) keeping the original settings (size, subtitles, languages). Plex kind of does it, but it's a pain to replace the original video with the optimized one (unless you want to keep additional copies, which wastes space). (Before anyone suggests using Handrake for this, yes, it's possible to do it outside of Emby, but it would be so much easier if this option were available.)

Hello,

at first let me say I am really psyched about the possibilities with emby. Love it, so I got premium member. :) One slight addition to this feature, would be really awesome, and time saving for me and maybe others. :D

Let me first explain, what situation I have got here. My Player doesn’t like my chosen audio-transcoding. Veryfied by downloading to my Device, trying to watch. Video is just fine, but no audio.

Here comes my kicking idea: I would love to have my server convert my audio from my mkv to the correct audio and leave my videostream as it is. Hope you are considering it.

Hi.  We already do this when we know the audio is not compatible with the device.

 

If you are having an issue, please create a new post with details so we can investigate.  Thanks.

Hi.  This exists now in 3.5.2.  It is called "Convert".

Hi, I cannot find it in 4.2.1.0 version. Where may I find it?

 

I've a lot of .m2ts files and my library would greatly benefit from this and free some space. Thanks!

Hi.  Click the '...' menu on any video item.

Oh ok, thanks! so there's no way to batch the process to the whole library and delete original files for now? Or to choose formats more suitable for high quality (h.265, VP9...)?

Yes you can do it on a parent folder.

Oh OK nice! So there's only the possibility to choose a better quality format that is currently missing.

 

Last question for now, which parameter is best suited to not lose quality and be usable on all devices, when saving some space? I would choose TV with Original bitrate but I'm not sure of my choice.

 

Thanks for making such a great software. If some things are missing for me (ability to retrieve data from Google Music for example, to send it on my UPnP devices, or to automatically start some media playing on some device at a given hour, to wake up for example, or to be able to select all media for an element to another in the list), I don't regret my lifetime premiere license :)

Thanks for the feedback. Why aren't you sure of that choice?

Thanks for the feedback. Why aren't you sure of that choice?

Because description associated with "Mobile" preset says its for all devices, and "TV" preset lists more precise devices. Furthermore, I don't know if "Original" bitrate is a good idea, or if a smaller one is great enough.

 

 

I just had a look at converting a file using TV and Original, and it seems not to use hardware decoding/encoding when it should use it (my intel graphics p630 supports it):
