how to convert MPEG1 to MPEG2?

[namsilat]

I have some old MPEG1 files that I like to convert to SVCD format. I tried using HT MPEG Encoder to do the conversion, but it doesn't allow change of bit rate and fix it at 2500, so the end result MPEG2 files are too large. I need to reduce bit rate so the end file can fit onto a CD-R. Unless there is a program that I can resize bit rate of MPEG2 file into a MPEG2 file with lower rate during encoding. I already tried TMPEGEnc and it doesn't "support" MPEG2 file as the source file.

But your source files are mpeg-1 aren't they

There is no real point to re-encoding from mpeg-1 to mpeg-2 unless you also need to resize to make them (S)VCD compliant, the quality will only get worse.

BTW TmpGenc will accept mpeg-2 files as source if you have the PowerDvd mpeg encoder installed, or you can frameserve from virtualdub-mod or dvd2avi.

I initially tried to merge the two MPEG1 files using TMPEGEnc, but somehow the end file only has some 20 minutes of the total 90 minutes betwee these two. It looks like when merging, it only took first 3 minutes of first MPEG1 file and first 16 min of second MPEG1 file. The time indicator was moving too fast for me to see it exactly, but sufficies to say that process did not work out.

I have a merged MPEG2 file after converting each MPEG1 file, at bit rate of 2500 using HT MPEG Encoder. I could not change the bit rate during the conversion, so if I can lower that MPEG2 file to 2000 bit rate, then I can fit it onto 2 CD-R80.

It sounds possible that one or both of your source files contain errors.
Try this.
Use TmpGenc mpeg tools to demultiplex each source file into seperat audio and video streams. If you get complete (full length) files from this, then re-multiplex them and merge the results.

The separate audio and video files from first MPEG1 file is less than 2 minutes each, while the second MPEG1 file yielded audio and video files of less than 17 minutes only.

Yep, your source files a faulty/corrupted in some way.

I can't think of a suitable method to try and fix them at the moment. Try a forum search or post a new topic to find what you need. Browse the tools section too, I am sure I have seen something that should help, just can't remember what it was at the moment, sorry

Maybe on of the guides here or one of the tools here ?
