> Where can i find the options & metadata for the webvtt & dvbsub encoders Neither the webvtt nor the dvbsub encoder have specific options, I don't understand what "metadata" means in this context. Generally, when asking for help on this mailing list, you are expected to post a command line you tested together with the complete, uncut console output (that shows among other needed information that you tested current FFmpeg git head, the only version supported here) and explain what went wrong. (If you really wanted to know about the specific options, please see my answer above.)

Carl hi,
Thank you for your reply! Actually i made this question several times last month (subject: NEED HELP PLEASE!! Soft subtitles DVB subtitles stream, 1080p size problem on direct convert a MPEG-TS video), before someone answered me, and i really appreciate this!! So, Here is my case: I have a MPEG-TS video file with one video and one audio stream and i am trying to create a direct video convert with soft subs, by adding a DVBSUB stream inside it. My original subs filewas a stl file with greek subs. After many workarounds i finally managed to add the DVBSUB stream, after converting the stl file into a sub file with idx. I used the idx, so i get the palette information correct. So the command i used is like this (see bellow for complete console output): ffmpeg -i testvideo.ts -i subtitles.idx -map 0:v -map 0:a -map 1 -c:v copy -c:a copy -c:s:0 dvbsub -metadata:s:s:0 language=ell -streamid 2:151 output.ts The video and subtitles size is 1920x1080, but the output.ts file comes out with wrong subtitles size. It looks like the dvbsub codec converts the dvbsubs stream in 720x576 size by default, rather 1920x1080?? Is there a way to force the subs into the correct size? Any options filter or flags? (Metadata have nothing to do with subs scaling obviously..) Or, is there another way (another codec maybe) to achieve that? I may attach any file needed for your help Thank you in advance!!

No, the subtitles use the input resolution of hd1080 but this size is not stored in the subtitle stream and the default size is pal (that gets stretched to match the video size). > Is there a way to force the subs into the correct size? I suspect it should work if you produce smaller subtitles (pal).
