If I join imported MPEG2 clips before burning they are re-encoded by both MF3 and MF4 but if I burn without joining they are accepted as complient DVD files??
If the same MPEG2 clips are joined using the Womble software the resulting file is also accepted.
So what is wrong in the MF join function?

Yes, thats what happened to me too.lindis wrote:If I join imported MPEG2 clips before burning they are re-encoded by both MF3 and MF4 but if I burn without joining they are accepted as complient DVD files??

I had to finally end up using DVDLab Studio and it worked perfectly without re-encoding.

Hi,
The program is working like it's supposed to.
Whenever you JOIN any mpeg2 files they must be re-rendered into one file to be a compliant mpeg2 file. There are many quick joiner programs out there and they don't work. They appear to work until you play the video in a dvd player and suddenly the dvd player says "Cannot play this disk".
This is whats happening.
You have one or more mpeg2 dvd compliant files on the time-line.
When you JOIN them your telling the program to make one file out of these multiple mpeg2 files.
Mpeg2 files are complicated and you cannot easily join them. They must be re-rendered and re-timestamped in order to properly join them into one file.
Womble is re-rendering them using "Smart_Render" and that's why Womble is joining them so fast.
To have MF3 or MF4 Join them using Smart-Render and do it quickly it's mandatory to make sure your "Project Properties" are the same as the source videos "Properties". While on the Timeline Right-Click on the thumbnail of a video and look at the files properties.
If you have MF4 you can use the EXPORT feature and learn how smartrendering works by first exporting the Joined videos together having the same settings as the source videos. The process goes quickly.
Now export again and change the framesize or the video_bit_rate to another setting and watch how the program can't use smart_render
and actually is forced to re-sample the video data. Takes forever.
Also in MF4 under "Preferences" there is an option "Create Index file for betore Mpeg Performance" or similar wording. If you play to edit and join you may want to have that feature ON to speed things up.
Also in MF4 you should EXPORT your videos that are edited or joined and then import that new video into the timeline so when you go to the burning stage all the videos are dvd_compliant and the program only has to create menus and the dvd structure.
Hope this helps,
MD

Maddrummer,
Your idea to export and than import joined clips to get a compliant file without going through a re-encoding process worked when I did a quick test, thanks.
However I got a couple of crashes when I tried to edit the MPEG clips. It might have been something I made wrong and I did not dig deeper into that. Until Ulead has solved the issue of importing DVD_VR I will continue to use the Womble program (Mpeg Video Wizard) for the importing and editing of MPEG2 files. They seem to know what they are doing when it comes to MPEG files, to bad they don’t have a simple menu and authoring step.

try editing DV AVI with womble 
Horses for courses I'd say. If Womble works for you, why not use it? Many people here are using other than Ulead programs for the capture step, what's wrong with that? I never edit mpeg clips and wouldn't join them either. That doesn't mean everybody has to do the same.-

Lindis,
Nice that the exporting worked.
When editiing Mpeg2 files with either VS or MF programs it's best to have the "Project Properities" equal to the source file properties. That manually sets the correct parameters for re-encoding edited material. Any Un-edited material should be smart-rendered and any edited material will be re-encoded. So the program should only re-encode the edited material if the "Project Properties" is equal to the source videos properties.
You can change the "Project Properties" for MF4 under the GEAR icon on the bottom on the window. When you hit the GEAR icon the present "Project Properties" are displayed. To change them hit the "Change Mpeg Settings". I have custom templates made up and then select the custom template I've created. Or, set the parameters manually under "Customize".
It would be nice if MF asked you if you wanted to change the "Project Properties" to the source videos like VideoStudio does.
On my Sony dvd recorder if I record something at the Standard_Definition which is the 2 hour mode the true average Video_Bit_Rate of the file is approx 4500kbs with Dolby Audio at 256kbs.
When I look at the Properties of the file it displays 9100 or 9800 as the Video_Bit_Rate (That's actually what the Max_Bit_Rate is.
I'll check the bit_rate using "Power_DVD", then set the proper bit_rate in MF4 to the correct average bit rate. This has prevented some files from generating errors.
I don't do alot of editing of Mpeg files in MF. I do join/cut/split them or convert the audio from one format to another. If I want to do heavy editing I'll use VideoStudio or another dedicated Mpeg editor. I use DV format for heavy editing because it the best format for editing.
Womble is supposed to be one of the best Mpeg editors for the money.
Hope this helps,
