I have a batch routine to convert .mp4's to .mkv's.
All I'm basically doing is using this to add a personalized COLORED .srt to existing .mp4, .mkv and .avi files.
This routine works flawlessly on doing .mkv to .mkv files. Come out just lie ORIG with my mods, non-jerky framerate.
Routine removes all existing subpics, add NEW colored subpic, adds/modifies, video, audio and subpic Descriptions via a .json config files.
Tried tweaks in VLC codec section, per https://windowsreport.com/vlc-media-player-lagging-windows-10/#2 ... no help there !!
VLC is my goto player .. same with MPC-HC
The jerkiness is slight, but enough to make you not want to watch it !!
Please assist..... THANKS in Advance @@

@netmask56 ... My ver is a little out of date .... using v.24 .. lol
@davexnet ..... about the same ... frame rate same
Need to do clean up on PC as MEDIA drives are FULL ... then test further
One good thing is its not my .bat routine ... MKVToolNik does the same thing
The other good news is it's related to the ORIG encoding as NOT all .mp4 test get the Beef Jerky effect. In fact its a very small percentage, 4 out of 20 to 30 muxed.
So hopefully by today I'll have an answer after more testing
PS: Gonna test with ffmpeg too so stay tuned
Embarrassed to say what fixed it ...... the outdated version
Bartender, get netmask a Golden margarita and a pint .... Cheers Mate !!!
