'Smooth' in the encoder results in HHR = Half Horizontal Resolution for high resolution clips. This means it will resample to half the width before encoding, and have the player stretch back after decoding. It will result in less sharpness.

For the bitrates discussed here, 'normal' and 'sharp' work pretty much the same way. I always use 'normal'. They only differ if the encoder has to drop frames, which it never does at reasonable bitrates. In that case, 'sharp' will rather drop frames, than decrease the quality below a certain threshold.

More bits means higher CPU load when the entropy decoder parses the bits. Bit parsing is not very MMX optimizable, since it is hard to do bit wise operations in parallel.

Have you checked the PDFs about 3DNOW?

Nope, sorry, finally had some time to work on improving RV9 encoding, and there's not much time left over, and to be honest, that's something I'd rather do as well. Improving decoder speed beyond what we have today, is very incremental and time-consuming, especially since none of us know the AMD extensions. I think most would want 20% better compression in RV9, in addition to RV on all sorts of cool devices, which is another large part of what we do, rather than 5% faster decoding on AMD.. Or no?

[p.s. not promising 20%, that was just picked out of thin air]

I see...

I'd like the 20% in encoding . I don't care too much about decoding, but some people have problems with speed.

About encoding, it would be great to add "lines" to the codec, for making shapes at low bitrate, for animes. I have one that is mostly blue and white, with lines. Lines are blury at 350kbps and require at least 700kbps to have greats one. If you don't know what I'm talking about, I can make screenshots.

Cya!

hum...

by 20%, do you mean 20% better at the same bitrate, or 20% faster?

Like I said, 20% was just an example, but "x% better" for the encoder would mean x% less bitrate to achieve the same quality. If you like you can send me a screenshot per e-mail.

That would be great

I'll reencode it (I deleted it) and shoot you a screen by mail. Do you the anime Ghost in the Shell? It's a special about Tachikomas, the blue armored suits, from the serie. It's ~5 MB, so I can shoot it in rmvb format, or a small clip.

[edit]

hum... what's your mail again?

Below are the clips from kilg0r3


1400Kbps

1000Kbps

SourceFrame


P.s.... how do i do so that there is a count how many times thes link has been clicked??

@iwod

Check your apache's logs

@kilg0r3

I don't see any differences between 1000k and 1400k. 1400k seems to lag sometimes, the sound gets out of sync for 2 ms. Quality is SO GREAT!!!

What tools are you using?

You are bandwith limited?

Remove the links in 1 or 2 days. So people that really want these and care about RV9 will have it, and the others nOoBs wont .

Yes, that is what i thought too.

I don't use anything special really but the source is extremely clean since it is sony's new highdef digi video cam.

Since you're not using hotmail, I'll try to upload the whole clip, which is 4.5 MB. Watch the lines on the tachikomas.

Here's the settings:

nope, pls use the web based file transfer service I mentioned in my PM, because our attachment limit size is 5 MB (which is less in binary due to ASCII conversion). Also, I still don't have your e-mail, which would be a more efficient way to communicate information not of interest to the rest of this board

I'll resend it using your wierd CGI upload

Don't have any FTP?

[edit]

Hum... My PM is empty. Could you resend it to my PM or mail? Thx

@ Karl...

I remember you have said that adjustable post filter would be added. I am having the feeling partly why Rv9 looks so good is because the filter.

I am wondering if it is possible to allow the encoder to have the options to force different level/kind of post processing @ different point of playing??

Or a Variable Post-Processing Engine

It would be nice to see a clip whitout and one with...
