Selling downloads of your film on your own part 7

I've started doing encoding tests for the 1080p version... breaking the download of it up into two zip files allow a little leeway but I don't want to go crazy and make a 10gb file...

The tests I had done up to this point were using the offline edit of the film... which is a 1920x802 24fps Quicktime movie using the PhotoJpeg codec at %100... perfectly fine for offline editing but it is a lossy format...

So yesterday I did some tests using the online edit of the film which is a 1920x802 24fps Quicktime movie using the Sheer 10bit... so its a lossless file.... and the initial tests were pretty good! Much better than with the offline one understandably....

I was still testing at lower bitrates of 4000 and 4500kbps and it looked pretty nice at 1080p... those are the bitrates required to keep the 1080p under 4gb... there are a lot of advanced options in the x264 codec and I used some of them that made encoding pretty slow but the quality is great...

But yeh so then I went looking for reference info for 1080p and encoding bitrates and the best info I could find was from the Piratebay ^ ^ Whenever those movie release groups release a title they usually include all the encoding info with the torrent like so....

So here's the info for a 1080p version of the new Sherlock Holmes film... its 129 minutes long and this file is 7.23gb... the comments gave it a 10 for video quality! ^ ^


Release Date: 14.04.2012
Store   Date: 04.05.2012
Cinema  Date: 22.12.2011
Runtime     : 129 Min
Genre       : Action Adventure Crime
Source      : BluRay
Format      : mkv x264
Video       : 1920 x 800 @ 5920kbps @ crf20
Audio 1     : AC3 DE 448 kbps
So by looking at that I know its possible to get a great looking 1080p H.264 file that will be able to split into two zips smaller than 4gb each...

This is some Underworld movie... its 88 minutes long and the file is 5.23gb... it was also rated a 10 as far as video quality goes by random internets peoples ^ ^

RUNTIME.......: 01h 28min
VIDEO CODEC...: x264, L4.1
FRAMERATE.....: 23.976 fps
BITRATE.......: 6747kbps
RESOLUTION....: 1920x800 (2.40:1)
AUDIO1........: English DTS HDMA-Core 5.1 Ch @ 1510 kbps
SOURCE........: Blu-ray 3D CEE 1080p AVC DTS-HD MA 5.1 -HDCLUB 

So I can assume that by using a bitrate around 5000-6000kbps I should be able to get a good quality 1080p encode without insane file size... and then there's this one which uses some secret techniques?!! 

Its the new Mission Impossible film which is 2 hours and 12 minutes long yet the 1080p file is only 3.39gb?! They using some kinda VOODOO!?! Here's the info...

Video Specs:
Container and Codec: MP4 | H.264/MPEG-4 AVC
Frontend And Writing Library: Ripbot264 | x264 core 120 r2120 0c7dab9
Bitrate: 3296 Kbps
Maximum Bitrate: 62.5 Mbps
Encoding: 2 Pass | High@L4.1
Resolution: 1920 x 800
Display Aspect Ratio: 2.40:1
Quality Factor (QF): 0.089
Frame Rate: 23.976 Fps

Seems they used a low bitrate at 3296kbps but an insanely high max bitrate at 62.5 Mbps 0_0 DAT must be the secret! So I won't give up hope on a 1080p file smaller than 4gb just yet ^ ^

Seems the magic one was encoded by a group/d00d called Icebane part of release group Kingdom... looking at their 1080p torrents their all under 4gb's and use data rates around 3000-3500kbps with a super high max bitrate... I must learn theY encoding secret! ^ ^

  1. Encoding: 2 Pass | High@L4.1

    This is your secret right here :3

    Basically as I understand it, the file renders "twice," the first time is kindof like where it will look for areas that can be compressed more and get an overall "idea" of what the final encode will be. Takes longer, but generally gives nicer results than one pass, with a generally smaller file size.
