5 years ago transcode-video has several "ratecontrol" systems, and you can read more about them here: https://github.com/donmelton/video_transcoding#explanation
The default system is treats the target bitrate as something of a guideline, and it will go over it to achieve a certain minumum quality. I think this is what you're seeing, the 1100 limit is just too low for the default system to maintain the quality it aims for.
There are 2 systems that don't have this behaviour:
--simple--abr
--simple treats the target bitrate as a hard limit, and it will never go above it. --abr treats it as a slightly softer limit, and will go above it for brief moments, but will always stay within the limit on average.
I'd try --abr first, and if that doesn't work for you try --simple
For example:
transcode-video --abr --mp4 --target 720p=1100 --720p --main-audio 2 --burn-subtitle 1 done/\[Man.K\]Hachimitsu_to_Clover_S1_-_01_\(Dual\ Audio_10bit_BD1080p_x265\).mkvor
transcode-video --simple --mp4 --target 720p=1100 --720p --main-audio 2 --burn-subtitle 1 done/\[Man.K\]Hachimitsu_to_Clover_S1_-_01_\(Dual\ Audio_10bit_BD1080p_x265\).mkvThe other thing I notice in the commands you gave is that you removed --720p when you specified the target bitrate, and this is why the output was still 1080p for that. You need to specify both --target 720p=1100 and --720p. The --target option only changes the target bitrate, and when you specify --target 720p=1100, it;s only changing the target bitrate for 720p output. --720p is what tells the tool out output 720p
For setting the "forced" flag on subtitle tracks before you transcode them (so you don't need to specify it in the transcode-video command), you can use mkvtoolnix-gui. It has a "Header editor" mode:
You can use this to change the flags, then go to "Header editor -> Save (Ctrl+S)" in the menu to save your changes

My first question :) I have some users on my Plex server that had bad internet access. The server can transcode but thats no the problem, looking the logs I find they always ended at 1.5mbps SD. Plex optimised on some worked and they start getting direct play at 720p if the bitrate was less than 1.5, over that they transcode again. I want to make a 720p that can direct play on them as Plex one usually is over their limit and go full down to SD. I alone with the Handbrake presets can't so I start googling and found your tool. Did a hurry test and your tool beat Plex by far. I used
transcode-video --mp4 --720p --main-audio 2 --burn-subtitle 1 done/\[Man.K\]Hachimitsu_to_Clover_S1_-_01_\(Dual\ Audio_10bit_BD1080p_x265\).mkvIt ended on the limitOn the help options y saw the option --target [2160p=|1080p=|720p=|480p=]BITRATE and then I tried
transcode-video --mp4 --target 720p=1100 --main-audio 2 --burn-subtitle 1 done/\[Man.K\]Hachimitsu_to_Clover_S1_-_01_\(Dual\ Audio_10bit_BD1080p_x265\).mkvBut the file keep the original 1080p format and doubled the size. What do I need to change to get a 720p version at 1200 to be on their safe zone? From the test also learned that no matter if there is only one sub, if its not forced its not burn by default. Thanks in advance and sorry If I'm not clear or use wrong terms.
