MKV Video is Jerky

[sambat]

Any opinions on what's causing the jerky movement.

(also, trying to upload a clip directly doesn't work).

There are some missing (dropped) frames

Any speculation on how it happened - it claims to be an HDTV rip and ended up 23.976 fps.
I only ask because I doubt it was recorded in North America because of the movie content and it had Romanian subtitles.

If we could see some of the unchanged original, we might be able to make more definite speculation.

How does one "rip" from HDTV? Do you mean it's a decrypted HDTV "capture" or recording re-encodced as 2:35:1 mkv?? Isn't the movie a British flick circa 1955 ? I doubt it was broadcast at 2.35:1.

Does it matter how it happened? Someone at some point decimated the (wrong and too many ) frames .

If you were a bit crazy you could attempt to re-introduce them by mvtools2. There is no automated way, there is quite a bit of manual work at least for the identification part

Here's a script that inserts motion interpolated frames:

I initially missed frame 43 so I had to add it at the end. The line can't be inserted between the fixes for frames 19 and 66 because the rest of the script would have be changed to account for the extra insertion. I probably missed a few others in the low motion sequences. Of course, it will take you a long time to step through the entire movie to locate all the missing frames. Once you're done you'll have to adjust the audio to match the new video length.
