Dvd rendering problem

[John Rofrano]

If my memory servers me, the Sony micromv format was a failed attempt that never caught on. Almost no software supports this format and since it’s discontinued, no software ever will. My advice is to sell the camera if you plan to edit your videos.

Probably the reason you are getting m2t files is because that camera stores it’s MPEG2 video as a “transport” stream and not a “program” stream that most editing applications expect. HDV is also stored as a transport stream which is probably why Vegas as able to capture it, but it probably didn’t get the field order right which is causing interlacing problems.

The interlacing for HDV is upper field first (UFF). PAL DVD is lower field first (LFF). I’m guessing that Vegas thinks the m2t file is UFF when in fact it is LFF. What you need to do is open the media properties and check that the field order is set correctly and if not, change it to the correct setting.

You can do this by right-clicking on the media in the Project Media tab and select Properties. Then on the Media tab check the Field order and make sure it is correct for your camera. I’m guessing that it should be Lower Field First but you should check the camera specs to be sure.

John,
Thanks for your reply.
Indeed, the problem comes from interlacing. The captured m2t files are UFF. Unfortunately there aren’t any information in the user manual of my camcorder about UFF or LFF.
So I tried the following:
1- Change the media properties from UFF to LFF as you suggest, then render with DVDPAL template. This still gives me a “shaky” result.
2- Keep UFF in media properties but change project properties deinterlaced option to “Blend field” then render DVDPAL template. The rendered file is not “shaky” anymore but one line at the bottom of the screen is “blinking” . However I’m wondering if this is a good method? Will DVD Architect will render again the file?

Oh, if you’ve changed the deinterlace method from the default of Blend Fields then this will definitely mess things up. You need to keep it Blend Fields. People should NEVER change this setting unless they have a specific reason to.

It should be fine now and DVD Architect will not re-render if you used the DVD Pal template and did not change the default settings.

Actually, the default deinterlace method was set to None, I set it to Blend fields.
Can you tell me when to change the deinterlace method? And why changing it?

Thanks

Yea, NEVER! This is one of those things where “if you have to ask… you don’t need to know”. But seriously, only if you are working with 100% progressive footage in a progressive project would even dream of setting it to “none” and even then it isn’t necessary because the footage isn’t interlaced to begin with. It’s just never a good idea to set it to none and every week people come here with interlacing problems because they set it to none.

The default is Blend Fields. This is the Vegas default when it’s first installed because this works in most cases and preserves the most detail. If, however, you have extreme motion where Blend Fields still shows interlacing, then you should change this to Interpolate Fields. What this does is throw away half the resolution in an effort to clean up the image. This should only be used when Blend Fields doesn’t work. None should never be used unless you have some specific reason. Like I said, if you have to ask the reason, you don’t need to use it.

If Blend Fields is not your default, then you need to make it the default. You do this by changing it and then checking the box that says, “Start all new projects with these settings“. Like this:

Hey guys I own a small production company here in south africa and i am a self taight vegas user i want to thank you both one for asking the question and second for the answer it has so helped me create better DVD’s

I have had a problem which is not the same as you guys were discussing but i thought i would just try something you said and it fixed my problem.

I has taken my about 7 hours of re making the DVD re-rendering ans i am so relieved that i have it all sorted tonight i will sleep like a baby

Brilliant thanks guys
