HandBrake supports OpenCL!!

It seems HandBrake supports OpenCL now:

Anandtech compares a couple of mobile CPUs. The Intel mobile IB Core i7 quad core with HT sees a 30% improvement with OpenCL whereas the 4 thread Trinity A10 sees a doubling in performance.

HandBrake is free which is why this is great news,and hopefully people with discrete desktop GPUs will see bigger performance increases.

Gpu encoding has finally come of age then?

Hurray!

Handbrake is simply the one we were most excited about. It will still be a little while before there are public betas of x264 and Handbrake, but it's at least something we can now look forward to.

Anyone know if it's in the nightlies yet?

It's only in amds basement apparently. Makes sense, handbreak never used opencl because the whole process had to be coded for it - if amds doing all the work for them I don't imagine they'll be upset with any delay. Certainly quicker than the implementation process for gimp or blender

Seems and has been busy though. The whole presentation points out opencl for de-noise in vlc, opencl compression added to winzip 16.5 and 30 something gup acc. effects in photoshop plus opencl blur. Plus the expected enhancements minor to steady video (also browser plugins), gup transcoding and buffering.

Be interesting to see how it scales on discreet gpus. Encoding is the most demanding, slow (damn blurays) thing most of us do, and a cheap crossfire box would be a real time saver. *crosses fingers*

So will these have any improvement for i5-2500K, I also have LucidVirtu..

Only the IB GPU will work as it supports OpenCL but AFAIK,OpenCL seems to run better on AMD IGPs(I think it is down to the way it is implemented in the Intel hardware).

So this should be a good boost to my 2600K + 7950? Re-encoding FRAPS stuff takes a while :rolleyes:

Forgive my dumbness, but is this software for formatting videos made with fraps to upload to places like Youtube?

Whatever editing package you prefer. I have a host of them from Camtasia Studio to Handbrake, MediaEspresso etc.

All of them seem to be extremely quick on my 2500K @ 4.3GHz and GTX570. My Fraps encodes are recorded at half 1920x1200.

Seems a little slow on my X3350 @ 3.7 and it's a quad core :\

It's not in the current version, it's in development..

It's for formatting anything. I use Handbrake to encode FRAPS recordings to 720p for Youtube, and films/shows to 480p for my mobile. The films/shows are pretty quick to do, but an hour long FRAPS recording can take 15 minutes to encode... When you have multiple recordings, well...
