How is this card for HD video Editing?

Doesn't the modest speed boost and good IQ stem from the fact that unlike Arcsoft’s Media Converter, TMPGenc does almost everything on the CPU, as I said above? Their Forum is badly written, can't direct link: Click

Somewhat, but what is done with the GPU offers the same (or effectively the same) result as if it had been done with the CPU, and those filters themselves do run many times faster, from what I can tell. Quality compression will need very low latency access before GPGPU can be used for more than video filters (embarrassingly parallel) and maybe some pattern matching (moderately parallel, if the program is written from the ground up to scale it out, and patterns can be searched for across a large data set). For now, a better approach is to do what the GPU can do well on the GPU, with good quality, so as to free up the CPU's resources to do other work, more than to speed everything up by a billion times.

If IQ must be sacrificed for the speed, and that IQ sacrifice is not part of IQ-related settings in the program, then IMO, it's not right, and is just using the extra hardware to have a gimmick.

I see, good to know.
Do you have any numbers that tell how much time you actually save by doing those filters on the GPU?

hi IdontCare,

I downloaded and tried out the "TMPGEnc Video Mastering Works 5" software trial yesterday. But I'm not able to use it properly, i think. Is the filtering applied during capture, or after it? I couldn't do it during capture. which version of TMPGEng are you using?

after capture, I loaded up the avi file, then tried to apply 'video denoise' filter, hope that is the correct one. However, with that, the video become kind of mushy looking, plus the audio was completely lost in the final output. of course, this was a clip that was shot indoors, not very bright.

I notice that both PD9 and Premiere Elements 9 now have some video cleaning features(noise, sharpness, other video effects), have you ever used any of that?

The filtering is done when you transcode the avi file.

So you have the avi file, you load it into a new job in TMPGEnc, in the editing window you apply the video noise filter and there should be two options (going by memory here, app is not installed on this computer) you will want to enable the "temporal" option and then play around with the range and magnitude settings to optimize the output in the editing window.

Obviously you can very easily over do it and make the output look like a water painting. The trick is adjusting the filter settings to get the output you are after.

No one but you knows what that looks like, hence there is no "one filter setting does all" button. What looks right to you may look too grainy still to me.

Here is a post I made on the speedup I saw after I made a GPU upgrade with a real-life transcode job.

For my filter combos I saw 20% speedup, which for my 4-5hr jobs was a significant speedup.

Its definitely not the 100x speedup that JHH was talking about a couple years ago, but it is a nice speed boost.

IdontCare: Ah, I wonder if the 'temporal' option is only avaialable in 'batch encode'? that feature is disabled in the TmpgEnc 5 trial i'll poke around some more to look for it today.

I expect I will definitely need to do this cleanup for the mini-DV videos, hopefully they will not be required with any new videos that i shoot with a digital comcorder.

X264 (CPU based) is the best quality trancoder out there. You can use any freeware video editor, these are very good:

Nice, not bad at all, 20% is quite a lot.
I'm curious why Adobe or Sony don't use GPU power for its filters when it's apparently doable without IQ degradation.
