Smaller than Expected M2V

[Whitey]

Using TMPGEnc to create a M2V file from Xvid for DVD, the files finish up smaller than calculated.

I have produced many M2V files with no problems until now.

I recently re-installed windows and everything else and now I have this problem.

Any ideas?

Can you tell us what is the length of the video in seconds, the bitrate settings you used to encode and the overall .m2v file size?

[Whitey]

Film length 5687sec

Bitrate 6246kps VBR

Overall M2V 2,965,929kb

Thanks

OK, you are correct, the file size it too small.

6246kps / 8 X 5687 gives 4.440.125 kb, (i.e. 4.33Gb).

Try playing the .m2v file with Windows Media Player. Check the overall length in minuteseconds. The file probably is cut short (perhaps the encoder aborted).

If the movie is complete, then obviously the bitrate is smaller than the one you think you have selected.

Encode it once more and see.

BTW, if the .m2v file is 4.33Gb long, you will have trouble fitting it with audio onto a DVD-R.

According to WMP the file is 50min 37sec which would explain the file size.

But a quick scan through shows the beginning and end credits!!

I have tried the conversion twice, with the same result.

It should fit on a DVDR with 192kps audio?

May be I should try another Xvid to see if its that, that is causing the problem.

Did you encode with CBR or 2pass VBR? It's not possible to predict the final size of a CQ_VBR encode.

Did you lower the framerate?

[Whitey]

I always encode 2 pass VBR, I'm not new to this and have sucessfully created many DVDs from xvid/divx but never had this problem.

I did not lower the frame rate.

Maybe I should try an older version of TMPGEnc
