GPU accelerated AVC encoding?
tried AVIVO in the past and it was never anything but poop.
tried cyberlinks espresso thing and it's the same. GPU usage on my 5770 goes to 18% but the output is carp. nowhere near what x264 gives me (not a lot of help in that it doesn't deinterlace properly and won't accept AVS scripts - not to mention that you can't choose any options at all). i was encoding a load of home movies over the last 3-4 years off a sony HD cam so obv took a while and hoped something out there exists to speed it up a notch. even if the speed-up was nowhere near the 10x increase and only doubled it (only - heh!) |

We are yet to see a GPUGU encoder that can beat x264 speed-wise while retaining equitable quality. This has been discussed a lot

tried espresso (as per my OP) and it's poop. what i don't get is, isnt is possible to just offload small things (assuming vid encoding can be broken down that much) onto the GPU instead of what they are doing now which produces nothing but crappy videos? small steps.

Computationally intense things are what need to be offloaded. However, computationally intense things have been hand optimized up to wazoo by the x264 team. It wouldn't be a simple case of "Copy this code and make it run on the GPU" |
