Problems conveting several file types like RMVB and MP4 etc

[tommyleepark]

Hello everyone.
I would like to say thanks for all the information on this website. It really has helped me a lot in the past.

Now I came across some problems that I can't solve, and need some help, so anyone who can give me an answer I will be gratefull.
(I am new here so I am not sure Iif i posted it in the right place. Sorry if that's the case)

I have an old computer, laptop Pentium 133, 64mbs RAM. I use it in my room to play videos and music, and that's just perfect, I just need to convert them to mpeg. (like if it was a VCD but in a pen drive)

It's ok when I am converting AVI to MPG1. It works fine. I use Avisynth scripts to edit the video if necessary (mostly to put subs or borders on it) and then I use TMPGENC to convert it.

Problem is when I want to convert RMVB or MP4 to mpeg1...
First, I can't get MP4 into Avisynth. It just doesnt load the video, gets an error message. RMVB loads just perfect.
Second, when I try to use other software I get these results:

Oxelon Media Converter: The mpeg file presents itself as having a bitrate of 100mbs or something like that. My old computer can't play it. I have cheked and the bit rate is correct, I set it to 600kbs video and 128kbs audio... But the result is always this 100mbs bitrate...

Media coder: Doesn't even work, just says that no file is output. I don't understand why, it used to work just fine!

When I use Avisynth to load RMVB into TMPGENC, the file is ALWAYS out of synch. The audio never is right with the video. I have tried with several diferent fps and it never works.

I am running out of ideas.
I have also thought about using VirtualDub to encode into an old version of WMV. But I can't, the only option I see is Windows Media 9. I don't have the older versions available.
In media coder and Oxelon Media Converter I can make those into wmv1 and 2, but then the files is not playable in WMP6.4 (even after I installed microsoft package that was supposed to update wmp6.4 codecs)

Am I missing something important??
Please, help me.
Thanks in advance. =)

Well, since no one has posted a solution, I will post it myself.
After searching the web, I was able to discover how to solve some of these problems.
In order for Avisynth to read RMVB files in the proper audio/video synch is necessary to use a little bit different script:

directshowsource("path file that you are trying to open", fps=number of fps of the video, convertfps=true)

it's necessary to add the convertfps part, due to the nature of rmvb files.

I still can't open MP4 in avisynth but I believe it's necessary a proper decoder apart of the normal FFDSHOW codecs that I use.

I will post the solution here if and when I find it.

THanks for posting your solution.

Can you play the mp4 in windows media player? If not try haali media splitter and in ffdshow be sure to enable to decoder for the codec in just your mp4s(identify the codec in files using mediainfo).

Hey there!
Thanks for the reply. =)
I am starting to think that my PC has so many software installed that it is causing some problems (I used to have installed some codec packs and splitter and such... until I discovered FFDSHOW lol).
I will try what you said, but maybe I will have to format my HD and re-install windows.

Also, another thought...
Why is it that when trying to convert files like RMVB and MP4 into mpeg1 in programs like Oxelon Media Converter and such, they appear to have a bit rate of 100mbs? It's something like 104500 kbs... I don't get it, the file size is correct, and the bitrate when I do the conversions is too... So why this?
Btw, I don't use Windows Media Player... I use Media Player Classic and KMPlayer

Oxelon Media Converter: The mpeg file presents itself as having a bitrate of 100mbs or something like that. My old computer can't play it. I have cheked and the bit rate is correct, I set it to 600kbs video and 128kbs audio... But the result is always this 100mbs bitrate...

600 kbps is a VERY low bitrate for MPEG-1 video. That's almost half the bit rate VCD uses. If you are correct in saying 100 mbps, that's too high. I can believe that your PC can't play that. You might try using something like GSpot or VLC (you'll have to look in the Information tab) to try to get a better reading of the bit rate.

If you want to skip AviSynth, TMPGenc can open almost every type of file there is. I don't know how to make MP4 open in AviSynth if directshowsource() doesn't work.

[tommyleepark]

Yes, I know 600kbs is low, but that's ok for me.
How can TMPGenc load MP4?? I tried and it just said it was an unsupported format...
I was trying to use Avisynth to load MP4 into TMPGenc. Like I do with RMVB. I make a avisynth script and import that into VirtualDub and TMPGenc.

I already checked FFDSHOW properties and it's correctly settled. I believe I will have to format my system and re-install. That sucks, but I think I have no other option.
I can't convert MP4 into mpg1 with a low bitrate (at least the file always says it is 100mbs).
Also, VLCPlayer and KMPlayer are great programs, but they need a certain cpu power. Like, they are light on the system, but not light enough to play in Pentium 133. loool
