Could someone do it?

If i encode to quick time could someone just use camstudio or camtaisia to copy my work? I was told you cant just save quicktime files to your computer. But is this a thing to worry about?

Yes, you can copy quicktime files onto your hard drive but i'm not entirely sure if you can edit them without severely affecting the quality. Encoding a movie twice really degrades the quality.

1- People can just copy Quicktime to your computer. Progressive files can be downloaded via Quicktime Pro, or be copied by accessing the browser's cache. Streaming files can also be copied- I don't know if QT Pro can do it or a 3rd party app is required.

2- Encoding a movie twice does degrade quality, but you don't have to necessarily encode it twice. You can convert the Quicktime to whatever format you want (i.e. uncompressed). Quality of course can't be better than the original downloaded Quicktime.

ANYTHING can be copied, including QuickTime. There is no way to
really safeguard your work. There are some ways to ensure that
most/some consumers cannot copy it, but that's about it.

DVD can be pretty safe if you are using a dual-layer media or get
it pressed with CSS encryption. However, anyone with the right
tools (which you can download of the internet) can still copy it,
normal consumers usually don't know these tools so they can't.

A better protection (currently) is using DRM. DRM stands for Digital
Rights Management and at least Windows Media supports it. Not
sure what other formats (like QuickTime) support it. However this
usually involves licenses etc. and thus money. Keep in mind that
if the license ever disappears (you stop paying for it) people cannot
continue to play your movie (on other computers, depends on the
exact DRM license being used).

There are ways to download a streaming QuickTime movie, and
there ways to circumvent QuickTime movies that do not allow
saving or editing. Yes it will make it a lot harder (so most consumers
don't know how to do this), but it can be done. In the end nothing
is safe, sorry.....
