great victories in the future

One other point: the --profile and --tune don't seem to pass through (not a big deal, you can set those options manually)

And what is the difference between "extra options" box, vs. the "use command line" box in the GUI ?

"extra options" - add parameters to gui
"use command line" use only him parameters and ignored gui parameters

poisondeathray
This options not supported in vfw: FRAMES/SEEK/MUXER/DEMUXER/INDEX/QPFILE/THREAD-INPUT/NOPROGRESS/VISUALIZE/TUNE/PRESET/PROFILE/SLOWFIRSTPASS
"use command line" disable all GUI-options and use only what you enter in edit-box.
"extra options" append you entered options to GUI-option.

Thanks guys nice work

But I have another dumb question: how to get log file to print? The console box opens and closes automatically

[komisar]

poisondeathray, you may use "--log-file c:\mu_encode_log.txt" (also --log-file-level supported)

from cli-help:

      --log-file <string>     Save log to file
      --log-file-level <int>  Log-file level information [2]

They probably would be supported after I make redesign of interface (where profile/preset/tune would be part of interface but most of other options would probably discarded [for advanced user there is command line options]).

[poisondeathray]

Thanks , I forgot to specify path...

PDR, does this mean we can now do (on Windows) what rallymax was trying to achieve?

Yes it's definitely looking like that (with the few exceptions that komisar listed several posts above). Need to do some more testing to be sure, and it still needs to be verified by a strict BD verifier. (NAL-HRD patch seems to being very close to officially being commited too)

Thanks for updating this. I haven't yet found a better method to capture to x264 from my card, and this may fix several issues.

Nice. I hope rallymax won't be too disappointed.

I'm currently encoding 720p30 in real-time in VirtualDub into x264vfw (Bugmaster's last build) on an i7 920 PC. I am using default settings but with CABAC disabled. With CABAC enabled, I drop a lot of frames I'm trying both CRF at around 25, and also with set bandwidth of 5mbps.

Bearing in mind it's real-time, it's VFW, it's AVI etc, I'm pleasantly surprised by the quality level but what settings could I work with to improve quality? Also, is there a DirectShow x264 encoder available as fully featured as x264vfw? I'd imagine the option to deal with dual frames simultaneously could improve efficiencies?

I hope you don't really use "default settings" without any modifications. At least change Threads to 0 (this auto) and increase B-frames number and Refs (also if possible [you use VirtualDub or its modification] enable VirtualDub Hack).
As for DirectShow x264 encoder the only one I am aware is MONOGRAM x264 Encoder (1.0.5.0)

Edit: I've switched to the x264 implementation in ffdshow and can achieve 720p30 real-time capture comfortably with CABAC and lots of other goodies in VirtualDub. I'm using LAME at 192kbps for MP3 compressed audio. The .avi files run fine even in Windows 7 media player.

The only issue I find is that the audio needs to be set +500ms in order to be in sync with the video - something not required with x264vfw.

Awesome!

A request, if anyone is maintaining this code:

It would be helpful if in one pass ABR mode, the GUI allowed for target bitrates over 20mbps. I would like up to 100mbps if at all possible. Though I usually just use CRF, ABR/CBR can be useful in certain scenarios

why not use crf 0 ? (or 1 or 2...)

Try new versions:
x264vfw_21_1538bm_22856
x264vfw64_21_1538bm_22856

I added pseudologarithmic slider for ABR with bitrate from 1 to 999999 kbit/s. Hope this would be enough for anyone .
