mpeg2>DVD?

[jimijames]

I am confused

I recently bought a TV card which records in mpeg2. I want to put the recorded files onto DVD using Ulead or something similar, but it is taking four hours to convert the files.

Why is this? I thought DVDs were also in mpeg2 format, so why do the files have to be converted (taking forever) ?

Does anyone know about this?

mpeg2 has a picture size of 480x480 pixels and an audio freq. of 44100Hz.
dvd has a picture size of 720x480 pixels and an audio freq. of 48000Hz.
All encoders take a lot of time to resize each frame of the video and resample the audio to a new frequency.
If speed is what you want try svcd2dvd (look in the tools section). It is VERY fast and will make any mpg dvd compliant. its not free but its cheap enough to make it worth it (£10) .

Spence is also confused.

Mpeg2 has any resolution you want , and any audio you want. (within reason)

If your MPEG capture is DVD compliant , Authoring it should take very
little time because it doesn't have to encode.
Legal reolutions are 352xH 704xH or 720xH where H is either 480 or 576

Ulead is slightly screwey. You have to deliberately tell it not
to reencode compliant files. Sometimes if you edit it will re-encode.

What was your capture resolution ?

Thanks for the replies.

Capture resolution is 720x576 (pal). 48000Hz

So, the files don't need re-encoding?

I don't think so , but Ulead might

[jimijames]

Cheers FOO, you are right. Ulead only re-encodes if you edit the clip. That's why it was taking sooooooo damn long.
But I'm still not keen on Ulead, so I'm trying TMPGe instead. Much nicer so far......

Thanks for your help....x
