Posted November 30, 2013 by . Tool version 0.130.2273 using OS WinXP

Brilliant software.

I use this commandline tool as part of a conversion sequence to turn TV captures into smaller .mp4s for later playback on a "WDTV Live" box.

The X264 commandline can be daunting to figure out initially (examples abound though, just search) but once you have a useful commandline then Bob's your Uncle. eg "my" commandline creates h264 video which is proven fully compatible with the WDTV Live in terms of the "video technical compliance stuff". Happy days.

X264, when combined with FFMPEG to convert audio and with MP4box to mux the video/audio into an .mp4, provides you with capability to create your own (repeatable) custom tailored encodes.

Fantastic.

Extreme compression might be a very good feature for Sharing in-contra to my previous comment. Still figuring-out quality settings for personal back-up.

Other ripping tools like Xvid4PSP, StaxRip, RipBot264, FairUse Wizard, MEGUI must be updated to this version accordingly.

v r1703 better compression, but, video loses overall sharpness.
it's disappointing.
Target Video Bit rate : 1 500 Kbps
Actual Video Bit rate : 817 Kpbs (Too Low than target results-in poor Quality)


Hope for better improvement in next release.

Simply the best implementation of H.264 spec.

It is a CLI tool so some patience is required to learn it, otherwise use some great GUI's like
Ripbot, StaxRip, or MeGUI.

Unless you device does not support h264 part 10 (AVC) then there is NO REASON why you should not be using x264, even if you are not a console God , there is plenty of GUI's that harness the power of this codec implmentation.

I have been an AVI with XviD and MP3 die hard fan for a LONG time! I just recently graduated to using MKV files and building my own chapters. THEN, I discovered that I can encode H264/X264 files and *directly* mux the AC3 audio from a DVD rip into an MKV.

What I did NOT expect was the quality of video as such low bit rates.

I very extensively use my Western Digital WD TV to play the videos I make on. When using XivD to encode 720 videos (1280X720), I *must* run at least 5000kbs to have a decent picture. With H264 (or better yet, x264.exe) the video quality is superior, at only 2500kbs!!!

Now I wish my Creative Zen would support 264, because it is leaps and bounds better than WMV9!!

I love this CLI tool, thanks so much to the author(s)!!! I hope to have a GUI built soon, and have plans on making a GUI tool kit for MKVs! Thanks!

With this codec,you have DVD-like picture quality on VCD bitrates!
IMO, the future is here, in this codec!

I use it with super encoder to batch convert dvb mpeg2 files of various framesizes. The speed is 1/4 realtime on my core 2 duo 6600.

The vfm version is faster (about 2/5 realtime). You can use it with virtualdub.

An excellent choice for those who like cutting edge solutions, or something with great future in front of it!

X264 is the best codec I ever used. Thanks to DeathToSheep for the unofficial VFW version I can stay using it with virtualdub.
I capture with Mainconcept PVR in MPEG2 (quality 32) and convert with VirtualdubMPG to AVI files (X264 -single pass bitrate 800)
With this combination of videotools I can put 13 episodes (50minutes/episode) of my favorite "Aspe murders" soap on 1 DVD and the quality is much,much better than VHS.



Posted December 05, 2006 by . Tool version 6.00 using OS WinXP
Ease of use 8 of 10 Functionality 10 of 10 Value for money 10 of 10 Overall score 9 of 10


After being skeptical about AVC H.264 I finally broke down and decided to try it for some iPod movies. The source files were MPEG-1 @ 1856kbps ripped from some high bitrate xVCD's I did years ago, I tried doing these with 3ivX and DivX 6.2.5 and wasn't pleased with the results especially on HDTV, I tried x264 using MeGUI and I am blown away by the 2-pass quality @ 700kbps. Even at a low resolution of 352x144 these movies look good (not great)on a 42" HDTV and the file sizes are quite small. MeGUI is a very powerful program but not exactly for noobs, When the ability for 640x480 iPod resolutions becomes possible this codec will be unstoppable!!

Better quality than XVID and a smaller file size. Use the latest FFDshow from Celtic_Druid for playback. Be aware that playback is CPU intensive - Not designed for < 2.0Ghz machines (yet).
