x264 quality sample

[Elmo]

First of all

Panic At The Disco - I Write Sins Not Tragedies (Live Oxegen 2008)

Xvid ~1500kbps with bars http://www.megaupload.com/?d=ZL9RHOL0

Xvid ~1500kbps fully cropped http://www.megaupload.com/?d=F9XXZAAC

x264 ~1500kbps fully cropped http://www.megaupload.com/?d=3DD7I22W


they're all about the same bitrate the x264 is slightly larger as the bitrate ended up being slightly above what i specified and the Xvid ended up slightly below what i specified.

Kaiser Chiefs - Ruby (Live Oxegen 2008)

Xvid ~1500kbps http://www.megaupload.com/?d=M31Q8X1L

x264 ~1500kbps http://www.megaupload.com/?d=M31Q8X1L

enjoy

woops,

the x264 link is actually this http://www.megaupload.com/?d=JEDZIFF3

i can't see any option to edit my post so yeah there.

Okay thanks for doing so many samples. Will give some feedback after i've gotten all of them.

[Elmo]

thanks no problem, the only thing is uploading slowing me down.

for anybody else who wants to play the files and are having any trouble get this the k-lite codec pack it will allow you to play x264, Xvid everything in windows media player or whatever http://www.free-codecs.com/download/...codec_pack.htm

enjoy, looking forward to feedback, will be able to do different bitrates and other videos if you want. if you'd like a higher bitrate i'd say the next step up would be 1800kbps.

Okay i've downloaded both XviD and x264 versions of the video. Both look about the same to me. The Xvid seems to have more brightness (or some technical term that i dont really know ). And lastly, is the average quality on the video caused by the low bitrate, or its just the source?

[Elmo]

pretty sure it's just the source, camera quality at festivals like that seem to be a bit crappy as there's a lot of movement and usually quite out of focus.

anyhoo if you wanna check if it's the source, i could do an encode at a much higher bitrate to check

maybe 1800kbps, 2000kbps, 2300kbps, 2500kbps. i'd prob go for 2300kbps to make sure it's the source.

but i'd say 1800kbps should be enough for future encodes. I do think 1500kbps is a bit low. Used to about 1800kbps being transparent on x264 encodes not sure about Xvid yet.

let me know what you want

[crash]

Okay go for 1800kbps to check the source. Also encode the orangina advert.

[Elmo]

Did a ~2300kbps Xvid to be absolutely sure, looks like it must be the source to me. I'll let you check it out for a second opinion when it's uploaded.

gonna do that orangina advert pretty soon =]

[Elmo]

here's the ~2300kbps Xvid. http://www.megaupload.com/?d=T5RCO2XU

orangina ad coming soon

[Elmo]

it seems that there is quality loss from yadif at deinterlacing

so i looked up the avisynth site and found a filter called weave which should work much better [url]http://avisynth.org/mediawiki/Weave/[url] so i'm gonna try that instead.

here is the orangina Xvid advert at ~1800kbps http://www.megaupload.com/?d=FSP51OST which is done with yadif.

i'm gonna write a weave script in and remove the yadif script and do an encode with it to see the difference

[Elmo]

x264 here http://www.megaupload.com/?d=HRXCPDFV

just gonna do weave thing now

[Elmo]

after checking that out, yadif is fine no problem with that

[crash]

Yeah its the source that has the lousy quality. Btw the orangina ad is really weird.

[Elmo]

i KNOW it's so so weird,


it must've been on like nearly every advert break in the one and a half hour recording and it's like a minute long and it's soo weird.

i added the other bit on at the end as it was at the very end of the show before the ad break started and there was something about it that i liked i dunno what it was it just had a certain something, juste un peu je ne sais quoi mais je l'aime vraiment, c'est tres drole. sorry got carried away there, school should be starting soon and i haven't been speaking french in a while. and while i'm at it i'll just use my favourite phrase which i think works in every occasion.

je viens de venir dans mon pantalons =P
