Good x264 encode command line for AMD Phenom II X6 1045T 2.70 GHZ

[wcwman18]

I am trying to encode x264 and I have very minimal speeds. Below I will include my batch file and my avs code and I hope someone can help me tweak things for better encoding speed.

Batch file

basic x264 : x264.exe --threads 12 --crf 19 --vbv-bufsize 1450 --vbv-maxrate 1500 --direct auto --level 3.1 --ref 5 --subme 9 --weightp 2 \
 --b-adapt 2 --b-pyramid strict --me umh --keyint 300 --min-keyint 30 --aud --output %1.video.mkv %1

720p x264 : x264.exe --threads 12 --crf 14 --vbv-bufsize 4650 --vbv-maxrate 4700 --direct auto --level 3.1 --ref 5 --subme 9 --weightp 2 \
--b-adapt 2 --b-pyramid strict --me umh --keyint 300 --min-keyint 30 --aud --output %1.video.mkv %1

Here are my AVS Scripts

Basic x264

LoadPlugin("C:\Users\Owner\Desktop\pack\DG\DGAVCDecode.dll")
Load_STDCall_Plugin("C:\Program Files (x86)\AviSynth 2.5\plugins\yadif.dll")
DirectShowSource("prelims.ts")
ConvertToYV12()
Yadif(0,1)
Lanczos4Resize(704,400,6,6,-6,-6)

720p

LoadPlugin("C:\Users\Owner\Desktop\pack\DG\DGAVCDecode.dll")
Load_STDCall_Plugin("C:\Program Files (x86)\AviSynth 2.5\plugins\yadif.dll")
DirectShowSource("prelims.ts")
ConvertToYV12()
Yadif(0,1)

Sorry about that. How would I change it?

[vivan]

Just use presets.

Use the "--tune" option that matches the kind of footage you are encoding, pick the slowest "--preset" that you can accept speed-wise and kick out all the other options. It's as easy as that

(In case you are going to author a BluRay disc, you of course have to keep those extra options required for BluRay compatibility)

Is it really the fact that I don't use a preset that gives me about 18fps while encoding or is it within my batch file or avs?

The preset system makes it easy to control the "speed -vs- quality" trade-off with x264.

In almost any case you will be better off by using the suitable "--preset" instead of trying to mess with the individual options manually.

If the encoding speed is too low for your purpose, then use a faster preset. If you want to squish out more quality (at the same bit-rate), then use a slower preset.

That's it! There are no "secret" options that will magically make x264 faster without sacrificing quality. It's all a trade-off...

(Nonetheless it should be clear that the presets only control the encoding-speed of x264 itself. It will not help if you are bottlenecked by your AVS script!)

Why do you use --vbv-maxrate and --vbv-bufsize? Are you streaming video over internet?

[wcwman18]

Based on the command line posted what would be a good preset example?

[wcwman18]

The reason I even questioned in the first place is because I have a friend on a intel i7 that gets about 50-60fps using the same command line with thread-input and I am surprised I only get 18fps

I don't know how your script looks, but a simple FFMS2 script would look like:

V = FFVideoSource("C:\Some Path\input.foo")
A = FFAudioSource("C:\Some Path\input.foo")
AudioDub(V,A)

Also note that Transport Streams (TS) are one of the formats that is not supported well by FFMS2.

I would recommend to use DGDecodeNV for accessing TS files, but you'll have to buy it (and it needs an NVidia card). DGAVCIndex is a dead project and has various problems that won't ever get fixed...

BTW: You know that you can hit "Edit" instead of writing several posts in sequence !?

Here is my current script. I do not have a NVidia card. I have a ATI Radeon HD 6450. Based on the script that I have how might you recommend I change it?

LoadPlugin("C:\Users\Owner\Desktop\pack\DG\DGAVCDecode.dll")
Load_STDCall_Plugin("C:\Program Files (x86)\AviSynth 2.5\plugins\yadif.dll")
AVCSource("post.dga")
ConvertToYV12()
Yadif(0,1)
Lanczos4Resize(704,400,6,6,-6,-6)

[LoRd_MuldeR]

Throw out the AVCSource() and instead insert the code that I just posted. Of course you would give FFVideoSource() the original video file, not the DGA file.

Also throw out the LoadPlugin(). Or, if FFMS2.dll is not located directly in your Avisynth plug-in's folder, change the LoadPlugin() to load FFMS2.dll instead of DGAVCDecode.dll.

Does that look right?

[LoRd_MuldeR]

If you don't need to load FFMS2.DLL explicitely (because it is in your Avisynth "plugins" folder) and if the file "post.ts" is located in the same folder as your AVS file, then yes.

[error]: Script error: there is no function named "FFVideoSource"

[LoRd_MuldeR]

So obviously you do NOT have the required plug-in DLL in your Avisynth "plugins" folder

Put the DLL in place or load it explcitely via LoadPlugin() from wherever it is located...
