Ah thanks heaps for the tips :D

In light of this, I will definately give x264 a go! I havnt tried it for a few months, and as you said its constantly updated so I'll give it a go ;)

Yeah I know AVC MP4 does have keyframes, but many encoders intelligently set that themselves based on the IBP frames is all i mean with the reference frame count and all that, that's according to the ISO 14496-10 AVC standard anyway I read up on that bit. The main reason for this is for internet broadcasting and/or terrestrial broadcast [eg digital TV] so that incase the signal is lost it won't completely 100% f*** up like say, an ASP MP4 would.... that's just what i read anyway its probably "chinese whispers" if you get me

Anamorphic? Umm... yeah it does work.... 640x480 AVC video, with 16:9 aspect ratio, it draws 100% correctly on my PSP and PC. No bars on the left or right side, and only black bars at top and bottom if needed. The PSP scales it down successfully to 480x* and the letterbox bars are perfect... I don't have to change the zoom or screenmode or anything on the PSP or PC it works straight away...

Yeah I know that MOV is the QuickTime format but I was just mentioning how GOM Encoder outputs an obviously different container - an MP4 quicktime-spec as opposed to an MP4 common-spec... if you've never used AVInaptic i suggest you check it out ;)

I'm just saying that YUV can be bad because grabbing the YUV output is the same as transcoding, it doesn't actually decode the frames > process > encode the frames it just "screenshot this frame, add that, screenshot next frame, add that" which is all very nice and good for speed but the GENERATION LOSS [artifacts caused by compressing already compressed content] becomes a problem here!

I know NOTHING about Quantizer encoding! I've done video editing and production for many many years in the workforce and personally, but half this stuff AVC has is all new to me!


Ah thanks again though guys I guess I will perform a face-off between MainConcept and x264, if anyone is interesting I will definately post as accurate as I can comparisons with videos and pictures somewhere when im done. But the fact that x264 supports B-pyramids.. i have a feeling its going to be the clear-cut winner :D

...not to mention it can use a custom matrix! Peace :)
