 | The first putton to click is "Open File..." The second one is "Analyze with..." "Analyze with..." could work for several seconds, but no more the 1 minute. If AutoX264 hang for too much, close it. Relaunch and select MediaInfo as analyzer. After hitting these 2 button AutoX264 is already ready to encode. |
 | You can also quickly load a MeGui profile (already bundled), in this way you are sure to use correct options. NOTE: File Size and Bitrate in Megui profile are ignored. You must manually set the Final Size. NOTE: Only on profile saved by AutoX264 the Size/CRF/Manual Bitrate are respected |
| This is how will appear the top of autox264 after hit "Analyze with..." |  |
| We can see the resolution detected, the framerate, numbers of frames and how many seconds in lenght the movie. We also have the AR and have the possibility to resize. |
| Using this slider |  | you can resize the movie to your preferred resolution. |
| When you want, you can click on |  | button to have a resizer preview of your file (with audio!) |
 | In this case the "Final MB(or CRF)" value is 18, AND plese note that check in on "1 crf pass". That mean you will do a Constant Rate Factor encoding with a crf equal to 18 (very good quality) |
 | In this case you will do a 2 pass encoding with a final size of 25MB |
 | As you can see AutoX264 could do a 1 abr pass : so a 1 pass with an average bitrate computed by autox264 2 pass : a two pass encoding, this way will guarantee the exact final size (Final MB) selected 1 crf pass : a quality encoding, 1 pass. The crf value is the one written on Final MB (or CRF). In that encoding the final size is unpredictable. But quality will be proportional to crf value selected (the less the better) Copy Video : in this way you can copy the original video, without reencoding. Please be sure that your video could be muxed later No Video: this will lead to an audio encoding only. So you feed a vob (video file is compulsory, no reencoding of audio file only), autox264 will output an mp3 or aac (for example) |
 | The default audio or AutoX264 is AAC, stereo, at 96 kbs. BUT you can select MP3 Audio, or Copy Audio or mute it (No Audio). You can select to normalize the audio volume too. Mp3 Mode will allow you to select if mp3 audio will be at cbr bitrate (constant) or abr bitrate (average) or vbr bitrate (variable) Audio PID is the audio track to encode, you can hit the Preview button on main panle (Resize&Crop) to view and ear the audio selected |
 | If
your input is an MKV , AutoX264 will be able to MUX (not encrust)
any number of already present subtitles from mkv input file to final
size (either mp4 or mkv) Using Eac3to, AutoX264 will extract the correct subtitle and will remux in final file. This options work with all CoDec (mencoder/ffmpeg/avisynth...), BUT HandBrakeCLI. Remember that input must be mkv. With eac3to 3.11, extracting vobsub (.idx/.sub) subtitle isn't working |
 | On "More X264 Options (3)" you can click on "Save X264 options" for saving, in xml profile, the X264 options as you have set. I strong suggest to save profile to \profiles folder, otherwise AutoX264 will not be able to see and use it AutoX264 will also save the manual bitrate, the crf or Final Size specified, but no audio settings are stored (for now) |
autox264_guide_10.jpg | Mencoder offer a good selections of resizers. The resizers are from more soft to sharper. Priority are for windows only and will set the encoding priority Mencoder will also offer a very good denoiser , HQDN3D, here you can select the level of denoise to apply. Manual Bitrate is for forcing AutoX264 to use a specified bitrate, the value you write will be used as bitrate in encoding. Aspect ratio will force mencoder to use the specified AR. Not recommed to use |
| Deinterlace will apply the deinterlace selected from list (Interlace, Telecine, change framerate...) | |
 | In this panel you have important options. On Subtitle Options you can browse for subtitle and allow mencoder to "Encrust" (burn on video) the sub or mux the subs in final mp4 or mkv file. Remember that Mencoder don't allow to you all subtitle formats, graphical one's arent supported. Graphical subtitles are supported by avisynth. "Mux to..." allow you to select the container, from MP4 (the default) to MKV, or M2TS "Follow ITU" will force resizer to use ITU specification on resizing |
| The "Use CoDec..." is the most powerful option of AutoX264. |
 | AutoX264 is a MULTI encoder GUI for h264 codec. AutoX264 allow to encode with: Mencoder, FFmpeg, X264.exe When selecting "Use AviSynth"... AutoX264 will force use of X264.exe |
| You have different way of "Use Avisynth"... , and every input file will prefer one to another decoder/interface "Use AviSynth (FFmpegSource)" can be used for all AVI and Mpeg2 input. "Use AviSynth (DirectShowSource)" can be used for ALL video files. You must be able to play the input file on Windows Media Player (you need the correct decoder installed... like ffdshow tryouts). When all decoder fails.. try this. "Use AviSynth (DGAVCIndex)" can be used for all m2ts files with h264 codec. It's the preferred decoder for m2ts and h264 file. "Use AviSynth (DGIndex)" can be used only for mpeg2 file (vob/mpeg/dvr...). It's the preferred decoder for dvd file When using AviSynth as backbone for encoding, AutoX264 will "translate" all X264 options in X264.exe options, the same for resizers and deinterlacer. Using AviSynth will use advanced deinteralce routines, much better then Mencoder standard. Moreover using AviSynth you can select varius kind of subtitles, from text to graphical one's. The encoding speed is very similar to encoding with Mencoder, but all X264 will be usable! | |

 | I will not explain the filters, use only if know what doing. |
 | AutoX264 support queueing of encoding. Clicking on "Add to Queue" will post pone the encoding till you hit "Start Queue". This option could be useful when encoding several files, and let the computer work over the night... |
 | If
you download the full package AutoX264 will automatically find all
needed software. Anyway you can always point to another software
release for mencoder/ffmpeg... "Save program path and settings" will save the path of programs and will save same useful options: Resizer to use , Denoise , Manual Bitrate, Deinterlacer, ITU (on/off), Delete temporary files |
| After first analysis with Mplayer, it if fails, AutoX264 will try to force ffmpeg demuxer |   | This often is compulsory with m2ts or "strange files" |
| After the analysis with Lavf, AutoX264 could not have all necessary informations, and so will prompt for user help. Remember that Resolution, Frame Rate, and Frames are compulsory. Remember also to use mediainfo as analyzer if Mplayer hang and AutoX264 isn't responding |  | |
