Hello everybody,

I read many times many topics in this forum, but still have doubts. It is time for final explaination eventually.
I have to mention that I have no simple answer from Cyberlink helpdesk too.

When I try to complete project preferences I can see Hardware Acceleration tab, where I can choose four options:

1. disable hardware acceleration at all
2. enable NVIDIA CUDA/ AMD Accelerated Parallel Processing/Intel Quick Sync Video technology to speed up video effect preview/render and disable hardware acceleration
3. enable hardware acceleration and disable NVIDIA CUDA/ AMD Accelerated Parallel Processing/Intel Quick Sync Video technology to speed up video effect preview/render and disable hardware acceleration
4. enable both accelerations together mentioned above

My questions are:

a. which part of hardware/software and what precisely is doing in every option (from 1 to 4).
b. what for the second choose is posibble when I do Produce or Create file ?

Each one does different things, Kind of the same thing but different.

It really depends on the Video Card Software and Hardware. Nvidia Video does not do some hardware acceleration for some formats that ATI does support. WMV is a good example ATI does, Nvidia does not.

And sometimes it is best to not use Hard Acceleration at all.

I know that on my system, there are some Video formats I do not dare to use Hardware acceleration because HA gives me errors and blocky effects in the produced video.

It is really a try it and see, if your system works good, then use HA, if you get errors and blocky effects, do not use HA.

If you have a fast computer, you will not notice that much difference in the rendering time.

Quick Sync in more than two time faster that other options (my system Win 7 64k, Corei5 3,3 GHz, 8 GB RAM).
I have always tought, that hardware coder is better than software one ...
