Help me to encode from Mpeg2 to x264... how i can use and what ?
Hi boys....... i'm a noob of encoding, i know and i tested some programs on XP SP3 and on Windows 7x64 (i have two pc connected on my lan if it's needed) and i need to be learn some tips about x264 encoder and encoding.. 4 example:
- What's a good quality/speed programs to use ?? - What's a good setting to use ?? Or other similar question.......... but this is my recent story about convertion. I have this full mpeg2 file copied from my Sony videocamera: Code:

But all my idea it's useless: I have tryed to load the source mpg on different virtual dub.... and the audio tracks and i don't know because the audio tracks it's been reports whit 4 seconds less respect the video!!! I don't know because from mediainfo i can see this difference and if it's virtualdub reports this wrong duration....... Sorry for this LONG post...... but i need to explain to you all attempt i try and i thinks i have post all information about my media i need to encode. Please give me a help..... thanks in advance.

I can edit my previous post.... i can add some information about my full.mpg.
Five minutes ago..... i also tryed to load full.mpg on VirtualDub. After the indexing i obtain so many error says: Quote:
The full.mpg it's the result of joining 7 different mpeg file copied from my videocamera....... this is the fist mediainfo file: Code:

Download MeGUI from sourceforge. Run it once and accept to download all updates.
Download Avisynth if asked and install it (if it doesn't install it for you). In its folder, you'll find a folder Tools and there you'll find DGIndex. Open your MPEG file with DGIndex and select Video > IDCT : Reference and Audio > Demux all tracks and if you want, select Audio>Decode AC3 to wav. Now hit File > Save and save the file as video.d2v (where video can be anything you want) The software will analyze the video file and create a .d2v file (file holds information which helps to decode the video and seek to exact positions in the video if you edit it) and extract the audio. You can now create a small avisynth script which will load the video and audio and synchronize : Code:
LoadPlugin("c:\path_to\MeGui\tools\DgIndex\DGDecode.dll")
video = MPEG2Source("C:\path_to\video.d2v")
audio = WAVSource("C:\path_to\audio.wav")
mix = AudioDub(video, audio)
mix
second line loads the video, third line loads the audio, fourth line takes video and audio and mixes them into a virtual file called "mix" and last line tells avisynth to send to programs that virtual file "mix". You need to save this as a text file with the file extension .avs - Open notepad, paste the code, change paths, go to file > save as , select all file types then enter name.avs This avs file now appears as a video file to various applications - for example, you can drag it on Virtualdub and virtualdub will think it's a video that you can edit and compress with various codecs. MeGUI also will open this AVS file and you can then choose one of those presets in the application to compress the video to H264 (MeGUI uses x264 to compress) and audio to AC3 or AAC. You can join several segments easily with Avisynth, you just give them different names : Code:
LoadPlugin("c:\path_to\MeGui\tools\DgIndex\DGDecode.dll")
video1 = MPEG2Source("C:\path_to\first_video.d2v")
audio1 = WAVSource("C:\path_to\first_audio.wav")
video2 = MPEG2Source("C:\path_to\second_video.d2v")
audio2 = WAVSource("C:\path_to\second_audio.wav")
mix1 = AudioDub(video1, audio1)
mix2 = AudioDub(video2, audio2)
mix = mix1+mix2
mix
Avisynth also has some other useful functions .. for example if your video has 1000 frames (at 25 frames per second that's 40 seconds) and you want to cut the last second you could just say mix = mix.Trim(0,975) and the last 25 frames and the audio is dropped.

DEFINITIVE EDIT and after goto sleep because it's italy it's 5AM
Now....... myself and helping from google i have found TSMuxer! Whit TSMuxer i have the source videocamera Mpeg file to obtain a large .ts file about 9GB....... after this i have loaded in last stable AviDemux and whit copy function i have extracted some little parts. I thinks the ways explained above using avysinth it's most "professional"............ but now go to encoding parts to mp4! I thinks this time it's better or it's better choice to use Avisynth script and MeGUI...... at this point i want to encode this: Code:
General Complete name : E:\0504-Esordienti\karim.mpg Format : MPEG-PS File size : 577 MiB Duration : 8mn 30s Overall bit rate mode : Variable Overall bit rate : 9 469 Kbps Video ID : 224 (0xE0) Format : MPEG Video Format version : Version 2 Format profile : Main@Main Format settings, BVOP : Yes Format settings, Matrix : Custom Format settings, GOP : M=3, N=12 Duration : 8mn 30s Bit rate mode : Variable Bit rate : 9 100 Kbps Width : 720 pixels Height : 576 pixels Display aspect ratio : 16:9 Frame rate : 25.000 fps Standard : PAL Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Interlaced Scan order : Top Field First Compression mode : Lossy Bits/(Pixel*Frame) : 0.878 Time code of first frame : 00:00:00:00 Time code source : Group of pictures header Stream size : 549 MiB (95%) Audio ID : 189 (0xBD)-128 (0x80) Format : AC-3 Format/Info : Audio Coding 3 Mode extension : CM (complete main) Format settings, Endianness : Big Muxing mode : DVD-Video Duration : 8mn 30s Bit rate mode : Constant Bit rate : 256 Kbps Channel(s) : 2 channels Channel positions : Front: L R Sampling rate : 48.0 KHz Bit depth : 16 bits Compression mode : Lossy Delay relative to video : 432ms Stream size : 15.6 MiB (3%) Menu I thinks i have setted some value wrong in encoding video parts, because i have try to start the encoding and after about 12 minutes the first pass it's pass...... but i have aborted during second pass after i have looked the extimated remain times it's be setted to about 2 hours! It's very long time... i thinks for only 9minutes of lenght of source mpeg file........ how i can learn how it's better to set the encode video parts of x264 ?? Another question about using MeGUI: - Where it's it the parts about resolution i want to obtain on output files ??? I need to add this information in avs script ??? - How i need to start the encoding..... what's the exact sequence ??? I need to use "AutoEncode" ?? Or "One-Click" ??? Or i need to manually to click on "Queue" ??? If this using Queue button it's exact... there 2 different Queue... one in video and one in audio parts... it's the same button ?? or i need to add in a exact order ?

Avisynth works in the background and makes applications opening those .avs files think the .avs files are actually an AVI file without any compression for video or audio.
So you can write commands in that .avs file and open all segments in the file and join them together and then when you open the .avs file in Virtualdub, Virtualdub sees the full video, without any compression for audio and video. Then of course, you can apply deinterlacing if you want to,crop, whatever.. and you can compress to xvid if you want to, anything you want. You can also open the .avs file with MeGUI and encode the video using one of the presets in MeGUI. You can read the documentation for Avisynth here: http://avisynth.nl/index.php/Main_Page MeGUI can encode AAC files but it uses an encoder that's not free (it's free download, but not open source, you have to agree to a license to download it and use it for free), you have to download it from Nero's website and put it in a folder, then go into Options > Settings > External Program Configuration and you can check there that you have the encoder and say where it is. You can download the encoder from here: http://www.nero.com/enu/company/about-nero/nero-aac-codec.php If you still can't encode to AAC from MeGUI, you can always go in Virtualdub and extract the wav file from the video, then go to nero aac's folder and encode the file to .aac . The encoder is very simple, you just open a command line in that folder and then enter something like: neroaacenc.exe -br 128000 -if c:\path\input.wav -of c:\path\output.aac -br 128000 tells the encoder to encode at an average of 128kbps (like vbr mp3, goes lower or higher a bit depending on how complex the sound) , you can use -q 0..1 to say a quality percentage, where 1 is the best quality possible, or -cbr 128000 to encode at a fixed 128kbps. After you encode the audio you can combine it with the encoded video from MeGUI, or you can use MKVToolnix or MP4Gui or mp4box or other applications (they're included in the Megui \ Tools folder ) You can also give the .avs file directly to x264 to encode the video, but MeGUI has some nice presets for that, no need to do it in from command line unless you're really curious. -------------- And if from mpeg i extract the AC3 and not the WAV what i need to put ? I thinks WAVSource it's wrong..... WAVSource is a command in AVISynth that imports wav files, it won't work with ac3 files. In DGIndex you have an option to tell it to decompress the AC3 files into wav. It's better that way. You can import the AC3 file directly using DirectShowSource or if you install some "plugins" for Avisynth, using the function names for those plugins. See http://avisynth.nl/index.php/Importing_media , that explains a few things. on IDCT...... i can choose different value....... what's it's the best ?? How i can know what's the best choice for my pc ? In the DGindex folder you'll find a manual, DGIndexManual.html Open the file and see. basically IEEE-1180 is the best quality, but it's slower. To the best of my knowledge, the quality difference between those is very small, and on modern computers the performance difference between those modes is also very very small. As for your other questions. You shouldn't care where Avisynth is installed, as you don't have anything to do with it. Use the DGIndex included in the tools folder of MeGUI, you know that one works. |

Whit the value on video encoding i have obtain another error: On config of x264 i have selected High@L3.1 but the output file it's Main@L3.1.... i don't thinks it's the same ?? or not ? Same problems on Audio tracks..... i have specifically to maintain a CBR to 128Kbps...... because the audio tracks in output file it's in VBR ?!?? Otherwise if you can help to found a better value option to set for obtain a good quality video... or you can suggest another simply tips&tricks for using/making avisinth script i'm here to study and learning it.. Damn... it's very late..... i need to REALLY go to sleep. OTHERWISE THANKS IN ADVANCE FOR FUTURE HELP AND THANKS FOR ALL HELP ALREADY GIVE UNTIL NOW.... |

Don't resize interlaced video before you deinterlace it.
You can resize your video to 720x404 or to some 16:9 resolution after you deinterlace it. It doesn't have to be hard 16:9 numbers. Or you can set SAR (Storage Aspect Ratio) to correct DAR (Display Aspect Ratio) without resize the video. To do that, you can set Force SAR 64:45 from Misc tab of x264 config if you use megui, or you can add --sar 64:45 in x264 command line if you use x264 in CLI.

The pictures in that forum thread are from 2011 : since then the x264 encoder has improved a lot and there are much better quality settings. Use the presets built in into MeGUI until you're confident enough to use x264 directly from command line and you understand the parameters.
If you don't see any profiles or x264 in the "encoder settings" drop down list, select MKV or MP4 first at file format. then you should see at least x264: *scratchpad* that means it's a template you can customize. Hit config button , then click on "show advanced settings" and put the mouse over each option to see a quick help. Some options are explained here: http://mewiki.project357.com/wiki/X264_Settings Your video is interlaced. If you resize before deinterlacing, the quality will suffer. Don't resize before deinterlacing. Don't resize if you don't have to. Leave it 720x576 and tell the encoder to save the aspect ratio in the video and the player will automatically stretch the 720x576 image and make it 16:9 on your screen. The difference between 512x408 and 720x576 is super small, x264 won't care about that unless you set a really small bitrate, like trying to fit 2-3 hours on a 700MB CD. Don't deinterlace if you don't have to. x264 has an option to encode the video interlaced. I believe the parameter is --tff (top field first) or --bff (bottom field first) - mediainfo tells you what kind of interlaced video you have. You can also set this parameter from the x264 profile you choose in MeGUI. The interlacing decreases the encoding efficiency a bit (as in you need to raise the bitrate a bit to get same quality as if you the video was not interlaced). Most players and pretty much all tvs detect that x264 encoded the video as interlaced and will do deinterlacing if needed at playback. Some players will be stupid and not do it automatically but they're very few and usually you can simply go in a menu and enable deinterlacing for that film. SAR can be calculated easily with this formula: 16/9 = X * Y * SAR so SAR = 16/9 * Y/X For example 720x576 16:9 16/9 * 576/720 = 16 * 576 / 9 * 720 = 64 576 / 9 = 64 720/16 = 45 So SAR = 64/45 ... hence --sar 64:45 Last edited by mariush; 9th April 2014 at 18:04. |

ok ok.............. all this suggestion it's good for me for next encoding i need to do
About MeGUI ?? After i have loaded the .avs file and i have maked the config in encoder...... what's the button to start the encoding process ?? Auto-execute or i need to add to queue the all operation manually ? I have looked i have avisynth 2.5 installed..... you suggest to install this ?? http://sourceforge.net/projects/avisynth2/files/AviSynth%202.5/AviSynth%202.5.8/Avisynth_258.exe/download I don't know if i have correctly installed it....... |

You can read the help and other online guides to learn about the various modes. I just queue it and then go to the Queue tab and start the job.
To test avisynth, make a text file called test.avs and put this in it: Version() Then open that file using VirtualDub File/Open video file. |

yeah.... i have try it:
paste this on test.avs...... loaded on VirtualDubMod and i obtain "AviSynth 2.60 build Sep 18 2013 [17:36:36]" Speaking about the quality ot output file... i have read the message above says: "....x264 won't care about that unless you set a really small bitrate, like trying to fit 2-3 hours on a 700MB CD...." Until now i'm ever using Xvid for encoders my files..... now i know the MP4 it's still better like than oldest xvid codec and i want to know and learn to use When i use xvid...... i have ever choose to fit about 90minutes in 700MB, speaking about x264 i thinks i can choose to fit about 100 minutes in 700MB... right ? For example whit a video of about 10 minutes i can obtain a file about 70MB ?? Another value i know ever i use xvid codec....... if the output file maintain a bitrate like 1000kbs the output quality remain good, all file i have in mp4 have a bitrate about 1500kbs...... i can use a bitrate like this value to obtain a good quality i thinks. |

For another only my personal testing... from full.ts i have extracted this another parts:
Code:
General Complete name : E:\0504-Esordienti\mariani.mpg Format : MPEG-PS File size : 1.03 GiB Duration : 15mn 32s Overall bit rate mode : Variable Overall bit rate : 9 483 Kbps Video ID : 224 (0xE0) Format : MPEG Video Format version : Version 2 Format profile : Main@Main Format settings, BVOP : Yes Format settings, Matrix : Custom Format settings, GOP : M=3, N=12 Duration : 15mn 32s Bit rate mode : Variable Bit rate : 9 100 Kbps Width : 720 pixels Height : 576 pixels Display aspect ratio : 16:9 Frame rate : 25.000 fps Standard : PAL Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Interlaced Scan order : Top Field First Compression mode : Lossy Bits/(Pixel*Frame) : 0.878 Time code of first frame : 00:11:50:24 Time code source : Group of pictures header Stream size : 1 004 MiB (95%) Audio ID : 189 (0xBD)-128 (0x80) Format : AC-3 Format/Info : Audio Coding 3 Mode extension : CM (complete main) Format settings, Endianness : Big Muxing mode : DVD-Video Duration : 15mn 32s Bit rate mode : Constant Bit rate : 256 Kbps Channel(s) : 2 channels Channel positions : Front: L R Sampling rate : 48.0 KHz Bit depth : 16 bits Compression mode : Lossy Delay relative to video : -112ms Stream size : 28.5 MiB (3%) Menu 1) Launch MeGUI... choose Tools and use "FileIndexer" and i have load this mpeg. After this i obtain "mariani.d2v" and "mariani T80 2_0ch 256Kbps DELAY -112ms.ac3". 2) After that i have use the tools -> "AVS script creator". On Filter click on analyse and the Deintelace it's correctly setted automatically...... on resolution the programs suggest to me to set 720x and the aspect ration it's automatically setted. Click on Save 3) The AVS it's loaded automatically on MeGUI... i have used the tools "Bitrate calculator" for obtain a output file about 150MB.... those suggest to me a 1350KBs. this value it's automatically copied in encoder.... 4) I have check some value on config for video.... i have RESET the x264 *scratchpad" clicking on "load default", Turn on "Advanced Setting" whitout touch nothing on all TAB value.... the only value i have change it's HIGH on AVC profile and 3.1 on AVC Level and "Automated 2 pass" whit bitrate alredy copied by Bitrate calculator. 5) I have set the AAC For audio. At this point i have click "Queue" on audio... the audio AC3 file it's been converted to obtain "mariani T80 2_0ch 256Kbps DELAY 0ms.mp4" 6) After that i have click "Queue" on Video section... after about 50 minutes i have obtain a file called "mariani.mp4" WHITOUT AUDIO TRACKS!! This file it's 150MB exact size and the bitrate it's exactly setted to 1350!! At this point my last pass it's muxed (whit mp4box from tools) the "mariani.mp4" and the "mariani T80 2_0ch 256Kbps DELAY 0ms.mp4" but i have obtain a file about 164MB: Code:
General Complete name : E:\0504-Esordienti\mariani-muxed.mp4 Format : MPEG-4 Format profile : Base Media Codec ID : isom File size : 165 MiB Duration : 15mn 32s Overall bit rate mode : Variable Overall bit rate : 1 482 Kbps Encoded date : UTC 2014-04-11 01:49:52 Tagged date : UTC 2014-04-11 01:49:52 Video ID : 1 Format : AVC Format/Info : Advanced Video Codec Format profile : High@L3.1 Format settings, CABAC : Yes Format settings, ReFrames : 4 frames Codec ID : avc1 Codec ID/Info : Advanced Video Coding Duration : 15mn 32s Bit rate : 1 350 Kbps Maximum bit rate : 2 204 Kbps Width : 720 pixels Height : 392 pixels Display aspect ratio : 1.85:1 Frame rate mode : Constant Frame rate : 25.000 fps Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Bits/(Pixel*Frame) : 0.191 Stream size : 150 MiB (91%) Writing library : x264 core 138 r2358 9e941d1 Encoding settings : cabac=1 / ref=3 / deblock=1:0:0 / analyse=0x3:0x113 / me=hex / subme=7 / psy=1 / psy_rd=1.00:0.00 / mixed_ref=1 / me_range=16 / chroma_me=1 / trellis=1 / 8x8dct=1 / cqm=0 / deadzone=21,11 / fast_pskip=1 / chroma_qp_offset=-2 / threads=3 / lookahead_threads=1 / sliced_threads=0 / nr=0 / decimate=1 / interlaced=0 / bluray_compat=0 / constrained_intra=0 / bframes=3 / b_pyramid=2 / b_adapt=1 / b_bias=0 / direct=1 / weightb=1 / open_gop=0 / weightp=2 / keyint=250 / keyint_min=25 / scenecut=40 / intra_refresh=0 / rc_lookahead=40 / rc=2pass / mbtree=1 / bitrate=1350 / ratetol=1.0 / qcomp=0.60 / qpmin=0 / qpmax=69 / qpstep=4 / cplxblur=20.0 / qblur=0.5 / vbv_maxrate=17500 / vbv_bufsize=17500 / nal_hrd=none / ip_ratio=1.40 / aq=1:1.00 Encoded date : UTC 2014-04-11 01:46:47 Tagged date : UTC 2014-04-11 01:49:56 Audio ID : 2 Format : AAC Format/Info : Advanced Audio Codec Format profile : LC Codec ID : 40 Duration : 15mn 32s Bit rate mode : Variable Bit rate : 128 Kbps Maximum bit rate : 131 Kbps Channel(s) : 2 channels Channel positions : Front: L R Sampling rate : 48.0 KHz Compression mode : Lossy Stream size : 14.2 MiB (9%) Language : Italian Encoded date : UTC 2014-04-11 00:55:30 Tagged date : UTC 2014-04-11 01:49:56 Becuase upper i have obtain a file mp4 whitout audio tracks ? Otherwise there is very good quality.. this is a screenshot from source mpeg file: http://i.imgur.com/TcsZfNo.jpg And this is the about same point in encoded mp4 file: http://i.imgur.com/xgNGGWn.jpg I'm totally noob..... but i thinks it's a good result...... At this point, if this possible, i want only to know how i can obtain the output mp4 whit encoded audio tracks directly whitout to muxed the two .mp4 file after all it's queue it's finished (and obtain i bigger file size i desidered). |

If not thanks....... encode audio and video separately and after muxing the two output mp4 files i don't thinks it's not a bigger problems for now...... |

Not an insult! I just said I like to do things manually. Don't read too much into a Google translation.
Here is one way for you: Configure and queue the video encode job. Make a raw stream! Configure and queue the audio encode job. Make a raw stream! Select Tools/Muxer and choose your container type, add the two streams you created the encode jobs for, configure and queue the mux job Go to the main page Queue and start the jobs I hope it is useful.

So, what would be better settings for you? What problems are you seeing with your encodes? Last edited by Guest; 13th April 2014 at 01:22. |

- in encoding speed... the default value it's Medium right ? I thinks if i set this to "Fast" or "Very Fast" i thinks i can obtain a more speed encoding but i can obtain less quality right ? Otherwise i have choose to use MeGUI for converts this my Mpeg2 because it's been suggested to me I thinks it's the best and easily solution to use Avisynth and x264 encoder............ Ok.. for convertion i have found the solution... but come back to join my MPEG-PS file. I have re-read all thread for example....... in the first reply i can see using avisynth i can join the mpeg2 files: Yeah... it's great solution using a manually created avs script.... but MeGUI doesn't not support the MPEG-PS in output but only MKV or Mp4, i thinks MeGUI doesn't not support the AVI output files or not if i want, for example, to use the xvid encoding instead of x264 right (but i thinks in this case i can load the avs directly on virtualdubmod and choose the encoding setting) ? *EDIT* But i otherwise thinks for all other my general question to use the italian resource I don't know it's this is official forum.. but i thinks i can opened and i can ask all information here: Quote:
