x264 HD 1280x720

[smok3]

i need a pretty fast, decent quality, qt compatible / easy on decode x264 command line (preferably 1pass vbr or quality based) for progressive 1280x720 stuff, any suggestions?

(the 'original' edits are in cineform codec)

- with curent command line i get just under 1fps on 2nd pass at bitrates around 8000, which is kinda slow :)

The MeGUI profiles are not good enough?

i will definatelly take a look at those as soon as they get published as something that looks like a command line (sorry, iam just not gonna mess with megui right now.)

got around 7-8 fps with something like:
--bitrate 8000 --bframes 1 --subme 1 --progress --filter "0,0" --threads 4 --thread-input
(on dual xeon 2.8)

1p good quality:
x264.exe --bitrate 1000 --ref 3 --bframes 3 --b-pyramid --b-rdo --bime --weightb --subme 6 --trellis 1 --analyse all --8x8dct --progress --no-psnr --output "" ""
1p intermediate:
x264.exe --bitrate 1000 --bframes 3 --weightb --analyse p8x8,b8x8,i4x4,p4x4 --progress --no-psnr --output "" ""
1p max speed:
x264.exe --bitrate 1000 --nf --no-cabac --subme 1 --no-chroma-me --analyse none --me dia --progress --no-psnr --output "" ""
Of course bitrate can be replaced by crf of your choice.

Just install it anyway, there is a "show commandline" option so you can c/p what you need.

[edit]
I just installed the latest version so I could copypaste CE-Quicktime for you.. But it crashes when I select CE-Quicktime. Too bad! Sorry!

foxyshadis, 1p max speed runs 12fps, now thats decent speed even for SD material, will comment on quality as soon as this thingy encodes (it is just few minutes.)

edit: looks really really good.

this is a lil cutout of my try, shoot with my digicam then edited with adobe&cineform, then x264:

(this is just some random unedited material, was testing the workflow.)

W3ird_N3rd, tnx for your efforts.

The funny thing is, if you use that it'll decode significantly faster too, since it's CAVLC instead of CABAC. Surprised just switching off CABAC and hex->dia gives a 50% speed boost.

[smok3]

this brings up additional questions (or should i start new threads?):

1.- is it better to turn off advanced encoding features at hi-def and hi-bitrate encodes with x264 (perceptual quality wise)
2.- is there a general max or/and avearge bitrate that will play fine from 'some generic brand' dvd on most machines without stutering - i mean the speed of the actual transfer, not the decoding efficiency here?

jjj jjkj

[woah!]

if you are going with 7500 as a bitrate then xvid would probably do just as good a job. i thought the idea behind x264 was to use less bitrate to get a good result.

maybe i am all wrong here tho.
