One vote for Cinelerra. It has its quirks, but if you work around them and save often, it's a decent package.
Hammering in a screw?
In the beginning was the Plan and the Specification.
And the Plan was without form and the specification it was void.
And darkness was on the face of the implementation team.
And they spake unto their Leader, saying,
"It is a crock of shit and it stinks"
And it was the Leader and it was the Project Head.
Now the Leader spake unto the Project Head, saying,
"It is a crock of feces and intolerably malodorous."
And it was the Project Head and it was the Department Manager.
Now the Project Head spake unto the Department Manager, saying,
"It is a container of excrement and its effluvium is very strong."
And it was the Department Manager and it was the Product Manager.
Now the Department Manager spake unto the Product Manager, saying,
"It is a vessel of fertilizer of overpowering strength."
And it was the Product Manager and it was the Centre Manager.
Now the Product Manager spake unto the Centre Manager, saying,
"It containeth that which aideth the growth of plants and strong it is."
And it was the Centre Manager and it was the Director.
Now the Centre Manager spake unto the Director, saying,
"It promoteth growth and it is very powerful."
And it was the Director and it was the President.
Now the Director spake unto the Vice-President, saying,
"This powerful new product will promote the growth of the Company."
And the President looked on the product and saw that it was good.
That's not an O.S. issue. If anything it is an app issue.
