Taking submissions for a small encoder comparison

[Sagittaire]

I have really better result here for Ateme with 2008 core

why don't you upload it and add it to the comparison?

[CruNcher]

I guess NDA doesn't allow him too

[shon3i]

@Sagittaire encoder used here is same as you have. its same generation.

[CruNcher]

It's not the same, or does your encoder have a INSANE mode ;)

[shon3i]

have, but i didn't manage to use it with 2pass RC. Some options are locked for single pass/VBR mode only. Since i aim to target bitrate/size, i use max possible settings for 2pass. Anyway difference between Insane and Ultra is real placebo, and waste of time.

[julius666]

when will the comparison start?

[Dark Shikari]

when will the comparison start?Sorry; been unexpectedly busy with work and some other things. I'll try to get back to it soon.

Do you already have a Microsoft Expression Encoder Pro 3 H.264 sample? I don't see one in this thread, so I am working on one myself.

I'm done encoding. For a two-pass encoder, it doesn't do a very good job of maintaining the desired average bitrate.

The Quicktime video appears to have completely screwed up brightness...

Ptalabvorm added.

It's actually a gamma thing. There's a decent workaround (that requires QTPro) but it's still []. It sucks that there are a lot of good broadcast/live hardware that will only allow video in .mov format.
Unless I'm mistaken x264 cannot be held in an mov container.


What about Sorenson3 codec? As old as it is, it is sadly still being used a lot of places.

Hi Dark,

Can we expect to see SIF1 v1.10 in the comparison?

:thanks:

I have created an up to date theora ptalarbvorm clip:

[hellfred]

Is there still no VP8 clip available for comparison? Or will DS create one when he starts the evaluation, as some bug fixes are checked in into the libvpx codebase each week?

[Blue_MiSfit]

I'm assuming the Ateme v2 test was generated by KFE v2? If not, I have an evaluation version coming in-house later this week and would be happy to contribute :)

If submissions are still open, here is a file encoded using Snow:

I'll also be getting an evaluation unit of Elemental Technology's enterprise encoding server. If this comparison still isn't finished when I get this, I'll definitely run through a test! I'm expecting big lulz if Baddaboom is even remotely indicative of their enterprise performance.

Their pitch was COMEDY, they tried to tell me that there was no software solution that could transcode to H.264 in real-time for 1080p. I told them to look at x264 ;)

Derek

[CruNcher]

Hehe i always wanted to belive that their PRO stuff is better nice to see if that finally is true ;)

[Blue_MiSfit]

@CruNcher:

I'm not sure it is any better!! They claim to be able to do 12 simultaneous 720p30 encodes on a 1RU server with 2x dual GT200 boards (i.e. 4 GT200s). As always marketing is such a broad oversimplification :(

Derek

[Adub]

You know, maybe then can do 12 simultaneous encodes. To complete crap quality. X264 in Ultra fast can do some pretty amazing things too when it comes to speed. ;)

[Blue_MiSfit]

I'm well aware :)

[shark37]

Much better snow encoding, at least without ghosting artefacts.
