Problems converting H.264 AVC to MPEG2

[Gwar]

Hello,

I'm having a hard time converting a H.264 AVC video file to a MPEG2 video.

I tried many programms such as multiAVCHD , avidemux, corel video studio 10, mpeg video wizard and dvdflick and with all of them I had bad results.
The audio is not synch and/or the video hasn't the bitrate (too low) I wanted/configured

The only good results were with The Film Machine. The converting progress went fine but before the dvd authoring and vob creation started, it shut down. I checked out the files it created and it was a
TFM_Enc_Video1.mpv and a TFM_Encoded1_Audio1.ac3.
I thought "great" let's just add those to DVDlab and author the DVD. But what do I see? the video runs 1:29:14 and the audio 1:29:19. The the results were not synch as I thought.
I don't know why film machine created 2 diffrent lenght but since those are temporary files it could be that something wasn't encoded right. The avc is synch by the way...

I really need a good working step by step tuturial how to convert a H.264 AVC encoded mp4 file to a DVD9 with an average bitrate of 8500 without lossing much quality.

thanks in advance for all your help

I would try avstodvd and freemake video converter and convertxtodvd(trial).

I just tried to convetr it again and now see the error in Film machine. here it is:


so the two length seem to be a result from the shutdown during the 98% ..

Use AviSynth + FFMS + HCEnc, reencode videotrack, mux with original audio track.

Sorry for DGDecode

thanks

but I have no idea how to use those programms converting my avc file.

Is there a guide anywhere? I couldn't find one

thanks

start notepad

create txt file with extension avs:

FFmpegSource2("Friday 7.avi").KillAudio()

put file in directory with your movie

run HCEncGui, load txt file with avs extension, run encoder

when I open the avs it has an error

OK, but You need download, unpack and put some files in AviSynth Plugins directory - FFMS it is a plugin for AviSynth.

http://code.google.com/p/ffmpegsource/downloads/detail?name=ffms2-r473.7z

use 7-zip to unpack http://www.7-zip.org/

all those files:

FFMS2.avsi
ffms2.dll
ffmsindex.exe

must be copied to the AviSynth Plugins directory (usually it is C:\Program Files\AviSynth 2.5\plugins)

After some time i realize that maybe Avanti + ffmpeg will be easier for You

FFMS2.avsi
ffms2.dll
ffmsindex.exe

must be copied to the AviSynth Plugins directory

You don't usually need ffmsindex.exe - it's a free standing program for creating index files outside of Avisynth, so you wouldn't want to put it in the plugins folder anyway.
