why does my output video have static noise.

[yari]

x264 --bitrate 480 --stats "" --bframes 1 --subme 1 --analyse none --me dia --progress --no-psnr --filter "0,0" --output NUL "2.divx" 800x600 && x264 --pass 2 --bitrate 480 --stats "" --ref 5 --bframes 1 --subme 6 --b-rdo --analyse p8x8,b8x8,i4x4,p4x4 --progress --no-psnr --filter "0,0" --output "final.mp4" "2.divx" 800x600

this produces something like the screenshot attached.

Because you cannot use a divx file as input. x264 treats it as a raw file which is why you end up with static. Why do you want to re-encode a divx file anyway?

[Dark Shikari]

x264 is an encoder, not a decoder. Its going to parse any input given to it as raw YV12 data.

Install Avisynth from here:
http://sourceforge.net/project/showfiles.php?group_id=57023&package_id=72557&release_id=366702

Then create a script file (.avs) with the following lines:
DirectShowSource("2.divx", Audio=False)
ConvertToYV12()

Finally run x264 like that:
x264.exe --crf=22 --output "final.mp4" "source.avs"

minus the "[code]" portion.

okay im using ffmpeg instead now....

it keeps crashing when i use libx264...what could be wrong ?

[foxyshadis]

We're not psychic. Crashing with an error message? Crashing with a generic windows error? What rev of ffmpeg, what rev of libx264, and how did you compile it or where did you download it? You might need to use gdb to figure it out.

[Selur]

you could also use ffmpeg and x264.exe, decode with ffmpeg and pipe to x264.exe ;)
ffmpeg -i "2.divx" -v 0 -vcodec rawvideo -pix_fmt yuv420p -f rawvideo - | x264 --bitrate 480 --stats "" --bframes 1 --subme 1 --analyse none --me dia --progress --no-psnr --filter "0,0" --output NUL - 800x600
ffmpeg -i "2.divx" -v 0 -vcodec rawvideo -pix_fmt yuv420p -f rawvideo - | x264 --pass 2 --bitrate 480 --stats "" --ref 5 --bframes 1 --subme 6 --b-rdo --analyse p8x8,b8x8,i4x4,p4x4 --progress --no-psnr --filter "0,0" --output "final.mp4" - 800x600

hey i am using the latest ffmpeg build on windows 32. it doesn't show any error log messeages. as soon as i start the process, it will say encoding..... and then ffmpeg crashes.

maybe its my computer? i tried it in school, it worked fine.

[Sharktooth]

the realk problem it's your downloaded movie.
re-encode from the original following the guides and you wont have any problems.
