h264 and film Grain

Postby Kalstyle on 06/3/2010, 12:30 pm

Hi everybody.
My new obsession is matching film look, using my hv30 and after effects.
Thats kinda ok.

Now, my new problem.

When I export my fimLook-video to h264, I loose the grain.
After a little research, I understood why that happens...and I can live with that.

Bottom line, for Not loosing the grain, I need to export the video with a high bitrate.

BUT (and here is where i hope you can help me), a movie trailer, lets say, for example, the trailer of Inception (http://trailers.apple.com/trailers/wb/inception/), the 1080p version, is at 10Mbps, and you can see a very good compression with a very good retain of the grain

So, I tried that bitrate with my grainy 1080p-video, and the result was really Not Good.
Even using 20Mbps, it wasnt good enough.

I tried differents programs to the conversion (Quicktime Pro exporter, Adobe media Encoder...) and differnts configurations (1 pass...2 pass...there arent too many options actually, at least using those programs) but the results are almost the same.

So, the question is, how do i get a fine grainy-1080p video at 10Mbp , 24fps?

Thank you people!

Are you exporting H.264 directly out of After Effects? If so, try to export it with no compression, or a lossless compression then compress it with Adobe Media Encoder or any other third party video encoder. I never use a gain effect so I don't know what's wrong.

No, I export form AE using photo-jpg compression, quality 90.
It, of course, keeps the grain perfectly.

My objetive is compressing that video using h264 and keep the grain, with this settings:

1080p, 24fps, at 10Mbps. (the settings of todays' quicktime 1080p trailers).

H264 should not get rid of your effects.it is just a compression.It does not alter the actual effects. I am lost as to why you would lose the grain?

I've had a similar problem. I eventually managed to get it looking pretty decent using Sorenson Squeeze, H.264, Multipass render (which takes ages) at about 12,000Kbps.

Andy, Im tring Sorenson Squeeze. AMAZING software.
Thank you very much for your recomendation.

By the way, it lets you choose 4 kind of h264:

Apple H264 (testing right now with this one)
MainConcept H24 (I believe this is what I've using so far)
Sorenson H264
Sorenson Mpeg4 Pro.

Did you try all this?

Thanks again.

I generally just use mainconcept, just make sure you've got it on multipass and you should be laughing.

Handbrake is a great, free encoding software with a large amount of control over h264. Under the "video" tab, theres a section called 'optimize video' and you can choose an auto-tune preset - and theres one for grain. It works really well. im using Constant Quality RF value around 16-18, very very nice results, almost identical to the original grain, way better than any of Adobe's encode capabilities, and for the same file size! hope this helps.
