Convert MPEG2 to MPEG1

[dZ0GE]

I want to convert MPEG2 video and its mp2 audio (elementary streams encoded by TMPGEnc) to MPEG1 system stream. How do i do it?

as far as i understood TMPGEnc does not import MPEG2 files.

How can i convert it?

Thanks in advance

Yep,you can open MPEG2 files in TMPGEnc in different ways,
you can use an AviSynth script to import the mpg file,or
you can use a mpeg 2 plugin,thats maybe the easiest method.
youll find the plugin here:

Read instructions carefully ;)

mp2 audio can be used both for mpeg-1 and mpeg-2 so you may just reencode the video and keep the original audio stream.

You should check the audio to see if you need to change the sampling rate of the audio from 48,000 to 44,100.

Easiest way - load them (the video and audio) in TMPG->MPEG Tools-> simple multiplex. Select MPEG1 system (non-standart) (or it was MPEG1 VCD (non-standart)). Click start. Wait :) .

But that would not convert it to a real MPEG1 stream. It still contains MPEG2 video. The video stream must be reencoded to MPEG1 before multiplexing.

There is no a single word about real MPEG1 in the request (or the question). Anyway VCDEasy will recognise it as real MPEG1 system stream. Of course I know very well that inside it is MPEG2. BTW the same trick is used by the people which DVD player doesn't support SVCD - it is known as "VCD header trick".
