By following the \"VCD To DVD Conversion Guide\", I seem to go no further than the m1v format for the video file to be used for DVD authoring. If I want the end result to match the NTSC 29.97fps 720x480/352x480 format, don\'t I need m2v instead?

The other day, I tried skipping your Steps 2 &3 and input the DAT file directly to be de-multiplexed (Step 4) and then use the Project Wizard to re-encode the pair of m1v/mp2 files, and although it took 2 hours or so to convert a 50-minute file, the outcome is a bona fide MPEG-2 file (m2v), ready for authoring along with newly transcoded wave file.

Only then did I find out about the \"other\" guide \"How to convert VCD/SVCD To DVD using TMPGEnc\". So, questions arose from these experiments/findings:

[1] Where in \"VCD To DVD Conversion Guide\" does it instruct users to convert the DAT/MPEG-1 file into an MPEG-2, if at all?
[2] Is it still necessary to use BeSweet if \"How to convert VCD/SVCD To DVD using TMPGEnc\" shows that you can use TMPGEnc Plus to do BOTH the video AND the audio conversion?
[3] To encode or not to encode? Is it why the procedure in \"VCD To DVD Conversion Guide\" makes it so much faster than \"How to convert VCD/SVCD To DVD using TMPGEnc\", as the former simply does NOT re-encode the file and make it a DVD-compliant MPEG-2 file?

Please help me to clarify these issues. Thanks a lot in advance.

Hi there.

The point you have to understand is this: you DO NOT have to convert the video to MPEG2 as MPEG1 is included in the DVD standards (which means that a DVD containing and MPEG1 is a valid DVD disc and is playable in all DVD players).
This way you save time (that you should spend to re-encode the files) which is about 5 hours and quality as the video is better than encoding it to MPEG2.

Abou tBeSweet you don\'t use it if you use MPEG2 and TMPGEnc, but as I explained before the \"VCD To DVD Conversion guide\" is the one you should use. If you have any more questions do not hesitate to ask!

Thanks for the reply.

You said \"quality as (of?) the video is better than encoding it to MPEG2\", besides the other advantage of saving time.

Just to clarify, do you mean letting the video file stay in MPEG-1 gives one better quality than the same file re-encoded in MPEG-2, tested and true, no mistake? Why would 352x240 be better than the higher resolution of 720x480?

And, do you mean 5 hours for a feature length movie?

Also, since you recommend the \"VCD To DVD Conversion guide\", why do you also claim with regard to the other guide \"How to convert VCD/SVCD To DVD using TMPGEnc\" that
\"There are more ways to do these conversions but the way show here is probably the best one\"?

You are giving me a hard time here! Cheesy

Yes leaving the movie as is gives better quality as if you change a movie from a lower resolution to a bigger one quality is decreased (it\'s like expanding a small picture to a big one).

Yes encoding can take up to 4 to 5 hours (with a decent PC).

Now that thing in the TMPGEnc guide in mean it in matters of difficulty, I maybe have to clarify these sentence!

Thanks for answering all those questions. It really helps conceptually. Too bad BeSweet is not a plugin in TMPGEnc Plus; otherwise it\'s going to be both fast AND simple.

Hi yl,

Try the MainConcept mpeg Encoder yl as it can convert a whole movie in just over 2 hours!
Recoding does reduce the quality, but not so much that it is noticable on a normal t.v. Cheesy
