You have so many in those examples. You have regular vibrato. Super slow and wide vibrato. turns, trills, slides, bow petting (play and release). I know you said that it is not the slides but it could be a number of other things.
Maybe you can give me the exact seconds and the notes being played.
Don't concern yourself with wasting my time. It's my pleasure.

I'm really no expert in "Persian" violin playing, but I am a good imitator. I don't know if I would be qualified to make such a video compared to the authentic players. In one way, I would feel like a fraud. The one thing that is clear by listening to these musicians is that they use a lot of dynamics and take advantage of the instruments characteristics very well.
If you make a Q & A, I'll definitely respond but please choose a "small" excerpt in your video as an example. NOT LONG.... If it is long, I am force to talk so much. I have trouble keeping videos short. When you see cuts in my videos it's usually because I just kept on rambling on and on.....

By ornaments, you are referring to the turns?

Sorry for not knowing what the style of music is called but you are more than welcome to tell me.

With turns, you can practice different patterns in sequence. You can play one turn starting with the 1st finger, then 2nd, then 3rd.... and play a scale doing a turn on each note up and down the scale to get used to doing them quickly and naturally. At first it will be clumsy but eventually it will smooth out and become a part of your playing. Speed comes with practice and remember to keep your fingers close to the fingerboard, not to lift too high.

Please do me a favor and give me some seconds on the video's you are wondering about a certain embellishment/ornament and we'll discuss each one by itself. It'll be easier this way.
A turn is when you play a note and go above, on, below, and back on again. Usually done very quickly and there are different ways where you don't necessarily play in the fore mentioned order. See wiki's illustration.
