I still can't say whether you have to change those values, since I don't know your machine
and your load. 

You will have to look for yourself. You can do this by using jconsole, visualvm or jstat.
You might also add gc logging and look at the logs.

If you don't want to bother, you can of course just put bigger values into the memory settings
and look if your load problems disappear. 

If you want to go that way, I would double the heap to 1024  and probably set NEW to an empty

In your special case I am guessing 
that you are not interested in the actual content of the video streams and that you should
enable the md5 sum option in the http sampler.
