Transcoding MPA to 48000k

[m00c0w04]

I have loaded an mpeg file into DVD-Lab and it demuxed the file. It said I needed to transcode the audio upto 48000k. The built-in transcoder crashes everytime I try to use it. I decided to try and convert the audio to MP2 in ffmpeggui but I got an 'Unknown format' error. I tryed doing the same in BeSweetGUI but no matter what I try and convert it always ends up at a bit-rate of 128Kbps even though I clearly set it to 224Kbps as I used the command line. Can anyone suggest a way around this or another program I can use to adjust the sampling rate to 48000?

Thanks alot.

Use TMPGEnc. Even the free version can do any mp2 or mp3 (especially with lame & toolame added). And you can always add ssrc for very high quality sample rate conversion--same plugin structure/gui pipelining as toolame, etc.

I don't think I've ever had TMPEGenc crash on me or give me weird errors, and it always gives me the bitrate I'd chosen.

Oh, and you can use an mp2 (aka mpa) for a source, as well as the destination. HTH!

Demux the mpg.
Load the AUDIO into ffmpeggui.
Make it AC3 for authoring in DVDLab.

reboot, I agree that AC3 is preferrable for DVD's, but the OP didn't specify that format, and I find TMPGEnc much less buggy than ffmpeg (gui or not).

If you have the tmpgenc AC3 plugin, great. If not, tmpgenc sucks at audio (mp2).
Ffmpeggui will generally work fine. Use Belight, or besweet, or headach3 if you prefer.
The TDA AC3 plugin is by far the best, and it is integrated with DVDLab Pro.
If you prefer mp2, DVDLab can transcode to that from .wav too.

MP2 doesn't suck at sound quality as long as the bitrate is right (usually 224 or 192), the soundfile has been optimized/sweetened, and a very high quality encoder is used (TMPGEnc with toolame). I have scores of VERY HIGH quality mp2's that I could email to you as examples, even back-to-back comparisons with AC3.

The big downside of mp2 is it's NTSC DVD non-compliance (which isn't that big of a deal).

BTW, BeSweet may be a versatile app, but it's gui is one of the worst I've ever seen. (and I've seen a lot)

Ah...I didn't say mp2 sucks, I said tmpgenc sucks at encoding mp2.
Toolame does wonders with mp2, so I agree there
If you set tmpgenc to use toolame to do the mp2, have it output elementary streams, and then transcode mp2 to ac3, you get good quality audio, and total dvd compliance.

Agreed, besweet's (lack of a useable) GUI, puts it right up there with CCE and avisynth in the noob's useablilty index
