Gray flashing frames in H.264 Conversions - Bad Avisynth Script?

[GMaq]

OK, Cool stuff!!
I run FFDSHOW and Haali Media Splitter on my machine, if I enable AviSynth Scripts Serving, and select Normalize in the FFDSHOW Audio options will that feed the encoder a normalized audio track? If so is this preferable to scripting it or is realtime FFDSHOW normalizing not a good idea?

I told you no more questions, apparently I'm big, fat and I lie!

So you want to normalize the audio before you encode it to aac/m4a ? Within Avisynth, all you need to do is add

Normalize()

to the script. This can take a number of minutes to run, as Avisynth scans through the audio looking for peaks and adjusts the volume accordingly.

DirectShowSource only cares about decoding the Video or Audio to something that Avisynth can process, so for the most part you don't need to worry about the additional features of a particular codec, as in the ffdshow example you asked about.

Conversely, if you rename your audio file to audio.mpa or audio.mp2 or audio.mp3 or audio.ac3, you can normalize and automatically convert to m4a with the script below.

If your audio file was an mp3, for example, you'd rename your file to audio.mp3 and double click on norm_audio.bat to process. Works really well. But try the avisynth and the batch method and compare.

OK,
This thread has been a great source of information and a great starting tutorial on AviSynth, If there are any other people that are at a skill level some where between me and my esteemed mentor "Soopafresh" looking for ways to achieve great H.264 iPod video, here is the latest version of "DirectShowSource" for AviSynth 2.57.

With the proper Codecs on your system (FFDSHOW recommended) it handles MPEG-1 and FLV sources without the gray frames issue. DVD and MPEG-2 sources may also work, but Mpeg2Source is preferable for that. With this version of DirectShowSource simple AviSynth scripts can be used with drag and drop encoders like SUPER, 3GP Converter (ssj2_goha's Hack is really good) etc and give good results, A step up from that would be MeGUI which is by far the fastest x264 encoding soft I know of. And for those with larger craniums Soopafresh's batch utilities above are phenomenal. Just thought I'd kinda summarize because a lot of people are asking about Hi-Res H.264 on the forums, and Nero is sure dragging it's feet on this one!!
