I'd definitely be interested in your handbrake settings. I tried using that but i found the quality to be worse than what i could achieve with VirtualDub. The problem i had with handbrake was it made writing/text a bit blurry where as VirtualDub was clear. I'm sure it was just an option i was missing or forgot to enable.

Load up Handbrake then do the following:

1. Drag and drop the file to encode
2. Under the presets click "High Profile"
3. Change the container to MKV
4. In the picture tab do the following:
   1. Anamorphic set to none
   2. If there are black bars then move the Modulus down to 8 then back to 16
   3. Select "keep aspect ratio"
5. Leave the filters tab
6. In the video tab do the following:
   1. Set the video codec to h.264 (x264)
   2. Move the slider for the x264 preset to slow or very slow
   3. Set the x264 Tune to either Animation or Still Image
   4. Set the Constant Quality slider to 22 (I have tried 17 and 18 before and it gives slight artefacting however unless you're really looking for it you won't notice it so 18 could work)
7. In the audio tab for the following:
   1. Delete all of the audio tracks then add a new one
   2. Have the default audio selected and choose the codec "auto passthrough"
8. Now click "Start" and off you go!

Nice one Gerard and Harsh for the testing and tips

Nice thread.

Would love to see how the budget end of cards compare, such as 750Ti and 760 (and AMD equivalent) if anyone can test them. As that's where my money will be getting spent.

Firstly you don't need brackets around x and y. Secondly that isn't the correct way to do it using that method. You'd do the bigger number divided by smaller to work out the proportion between the two.

The 'correct' method is (using your terminology of x and y):

(y - x) / ((y + x)/2) * 100

I'll leave it after this as I can tell people are getting bored (but at least we're not arguing about technology we're still speculating about).

Using your formula:

If normal fps was 100 and DVR fps was 50 you'd get:
(100 - 50) / ((100+50)/2) * 100
50 / 75 * 100
0.667 * 100 = 66.7

So 66.7%

Now if you had 100fps, dropping down to 50fps is not a 66.7% performance hit, nor is it 66.7% of the performance. I think we would all say that in this scenario the performance drop was 50%.

(50 / 100 - 1) * -100
0.5 - 1 * -100
-0.5 * -100 = 50

So 50%

100 fps normal, 75 fps DVR

(100-75) / ((100 + 75)/2) * 100 = 28.57%

Does a 25fps drop from 100fps seem more like a 25% drop?

((75 / 100) - 1) * -100 = 25%


The percentage difference between the numbers is different than finding the percentage drop.

Yes thank you Googly. I do project work mainly for actuarial departments so I know the difference between a drop and difference . It isn't my formula it's THE formulae for a percentage difference. You're coming at it from a different angle and a different way of thinking.

The way you're thinking the calculation should actually be (50 - 100) / 100 so -0.5 i.e. a 50% decrease. So it depends what exactly the percentage is being labelled as. You should be using the difference figure though really.

Which plugin?

I ain't forgotten I am just away from home till thurs and need my PC to respond
