When I open a pre-encoded MPEG in vision express 3, does it re-encode the file? eg I encode a MPEG in TMPGEnc, then add menus and chapters using vision express 3. I understand that the menus and chapters have to be encoded, but does it re-encode the MPEG as well? I ask because I assume that this adds to the time taken, which is very long as it is. Also, if I write the image to hard disk instead of burning to CD, can I then burn the image using Nero Burning ROM? I looked in the "burn" screen, I can't see the option to save to hard disk folder. I assume that saving an image is the same thing? I just want to able to burn the image in Nero- speaking of which, would I have to choose "burn image" or "create VCD" as I normally do?
This isn't really an answer but if an mpg created by another program is opened in NVE, it isn't reencoded when "enable smart encoding" is checked; more>video options. Eg, a 2 1/2 hour video that was encoded in about 5 hours by another program was burned to DVD by NVE at 4x in less than 1/2 an hour, longer than my usual authoring program but only by a few minutes. You could try that and you should be able to tell by the time given whether it is encoding again. Either way, it will say transcoding. Perhaps, the Nero forum here could better answer you.
Thx mistycat, your answer more or less covers what I wanted to know. I'll give the "enable smart encoding" option a whirl, and see how long it takes.
