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")

Sorry about that. How would I change it?

[wcwman18]

Just use presets.

What preset would you recommend for what I have written?

[detmek]

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

[LoRd_MuldeR]

What preset would you recommend for what I have written?

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)

[wcwman18]

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.

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?

[LoRd_MuldeR]

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!)

I get about 94-96% cpu usage during my 720p encodes. Does that seem to you like a bottleneck issue to you?

[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

[LoRd_MuldeR]

I get about 94-96% cpu usage during my 720p encodes. Does that seem to you like a bottleneck issue to you?

CPU load doesn't say anything here ;)

If you are using heavy filtering in your AVS script and these filters are multi-threaded, it can easily happen that the total CPU usage reaches 100% while ~90% of the CPU time is spent in Avisynth ;)

What matters is throughput and throughput is measured as FPS.

If switching to a faster x264 preset doesn't increase the throughput, you probably are bottlenecked by Avisynth. Otherwise you probably aren't.

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

I would suggest to start with something like "x264.exe --tune film --preset slower -o <output> <input>" and check the throughput.

If that is too slow for your requirements, switch to the next faster preset. If that's still too slow, switch to the next faster preset again. And so on...

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

At this moment the Intel Core i7 is the fastest (consumer) CPU available while AMD is far behind, so not much of a surprise - even though you don't mention what model he has exactly ;)

Anyway, as long as your friend doesn't encode with the identical Avisynth script and from the identical source file, the numbers aren't really comparable - even if the command-line is identical.

I did what you suggested and got about the same speed. Anything that could be causing this?

A little detail on my setup. I use a HD PVR to capture my video which records to a .TS file. Then I edit that file in Videoredo and then start my encode with the scripts and command line above.

Few ideas:

test how demanding your AVS script really is - use AVSMeter (http://forum.doom9.org/showthread.php?t=165528) to get an idea how fast the script can actually run on your system
replace your source filters - DirectShowSource is the least recommended one, use FFMS2 (http://forum.doom9.org/showthread.php?t=127037) or if you have NVIDIA compatible card try DGDecNV (http://neuron2.net/dgdecnv/dgdecnv.html) which offloads video decoding burden from CPU -> GPU (or better said, dedicated VP engine that's built into a graphics card)

Once you know how fast your Avisynth script is you can tell if x264 encoding can get any faster or not ;)

Also, the functions exposed by up-to-date FFMS2 are FFVideoSource() and FFAudioSource(). The FFmpegSource2() function is only a wrapper function defined in some .avsi file...

[LoRd_MuldeR]

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?

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.

Just installed avisynth 2.5.8 same issue

[LoRd_MuldeR]

Looks like Avisynth (or more likely one of the plug-ins involved) has crashed.

Do you use the "stable" Avisynth 2.5? If not, I would suggest trying with that one first:
http://sourceforge.net/projects/avisynth2/files/AviSynth%202.5/AviSynth%202.5.8/

Furthermore you should clean up your Avisynth plug-ins directory. I encountered strange crashes with "buggy" plug-in DLL's, even when that plug-in wasn't even used in the script.

Also you may want to kick out Yadif for now (you can re-add it later). Last but not least you may want to try the last official FFMS2 release from here (http://code.google.com/p/ffmpegsource/downloads/detail?name=ffms-2.17.7z&can=2&q=).

Thank you. That did the trick. Sadly that even with the presets I still only get 16-18fps while encoding video

[LoRd_MuldeR]

Using the Preset system does not speed-up things per se!

The x264 presets simply provide a very convenient and foolproof way to tweak the "speed -vs- quality" trade-off. If your goal is to squish out more speed, you have to switch from your current preset to a faster one.

If switching, e.g., from "slower" to "faster" preset doesn't give a significant speed-up, you are very likely bottlenecked by slow input. As mentioned earlier, you can benchmark your AVS script with AVSMeter (http://forum.doom9.org/showthread.php?t=165528)...

(You certainly won't be able to encode any faster than what AVSMeter reports for your input script, even with the "ultrafast" preset)
