I’m using version 2.4.9 with the following profile settings:įfmpeg-video=-ss 0 -vf yadif=0:-1:1,hqdn3d -vcodec libx264 -b 1800k -x264opts me=hex:trellis=2:subq=8:partitions=all:8x8dct=1:ref=5:rc-lookahead=50:keyint=25:min-keyint=20:bframes=3:weightb=1:level=4. So far the only subtitles I have gotten out of MCEBuddy are a single track converted SRT file which is added to the MKV. Following is an example of a H264 media file that contains embedded closed caption titles. I was previously doing this with handbrake through the gui.

I’m converting from mkv to mkv and just compressing the video down. If the value attribute is not present, the Representation contains a CEA-608 based closed captioning. The closed captions stream groups are separated by space.

The Accessibility descriptor shall be provided with schemeIdURI set to urn:scte:dash:cc:cea-608:2015, and an optional value attribute to describe the captions. Map string which specifies different closed captions groups and their attributes. Is there any way to keep multiple unconverted subtitle tracks on an MKV file. Used for signaling of CEA-608 caption services. Subtitles are the one thing I’m stuck on so far. I’m working on automating the compression of my backups and so far have had mostly good luck replicating the manual process I was using.
