video connection flickers

Rager01 · Post by **Rager01** » Sun Aug 19, 2007 10:10 am

when I connect 2 videos with MF 6 the result is flickering or blurred. This you can see specially when the video moves (for instance when you have filmed from left to right or right to left).
This error also exists in MF 4, but there I know a solution (but this didn't work with MF 6): new project, put the 2 video in it, in the project settings UNmarking the button "convert compatible MPEG files" and "2-pass-coding". The generated file I can use now in a new project.
Does anybody know how it works with MF6?

Have you selected the correct field order
Analogue source (e.g. TV card) - upper field first
Digital source (e.g. DV camcorder) - lower field first.

of course. Maybe you can try it yourself. In MF4 everything is correct (with my solution), since MF5 not. Maybe you can see it only, when you compare the 2 results. The connection with MF6 is like when you have drunk something beer

does no one else have seen this problem?

The solution to your problem is probably very simple but your making it a mystery with your solution?

What is your solution? Drink or don't drink, You shouldn't drink & drive to MovieFactory.

Sounds like what Steve says, your not setting your fields correctly in MF6, make sure your project settings match your source video settings.
Highlight the video on the timeline & click on the "I" (information icon) to display the source videos properties.
Depending on your target your Project Properites (under the GEAR Icon) should match your source videos properties.

sorry my English isn't that good that I can correctly describe what I see on my video. But I think you understand what I mean.
My project settings are everytime the same like my video settings. No differences.
My solution, how it works, you can see in my first writing in this thread, so there is no mystery. But it only works in MF 4 (German version)

Rager01,
OK, I now understand (after reading your original post), in MF4 you are forcing a re-encoding of the video.
First, in MF6 make sure you have downloaded & installed the latest patech to MF6 from the ulead website.
http://www.ulead.com/tech/dmf/dmf_ftp.htm#patch2
Reboot the machine.

In MF6 you need to make your project settings the same as your source video parameters. Right-Click on the source video and select Media Properties (write them down), or click on the "I" icon to display the video/audio parameters.
Then under the GEAR Icon -> Change Mpeg Settings -> Customize manually set all the parameters the same as the sourc video.

MF6 defaults to Lower_Field_First, It sounds to me like your source videos are Upper_Field_First. This would cause your problem.
So change your "Project Settings" to Match your source video settings and Force a recode by unchecking "Do Not Convert". It really sounds like your "Field Order" is being reversed. Probably should be Upper_Field_First.

There is a German Ulead Web Board. Maybe someone can provide the link to it.

thanks for your help. But my settings are correctly:
(but I've tried it with patch 1 - in the next days I will try it with the new patch)
- I always have lower field first (it is the correct setting for videos from a digital camcorder).
I did it in this way: record AVI Files from camcorder, then I render all the project, then I copy the new MPEG files from the temporary directory of MF in my Videos directory. Then I make a new project and import the MPEG video files to it; then I connect some MPEG files (with the same field order and the same like in the new project settings) and the result isn't good.
This step (making first MPEG and then connect) I do because when I connected 2 AVI Files in MF4 the result was also bad.
But I see, I have to try it again in MF6 Patch 2.

Yes, definitely install patch#2. Encoding quality is excellent.

In MF4 you don't need to get the mpeg2 files from the temp directory. The dvd is encoded in accordance with your "Project Settings".
Simply Highlight your DV.AVI file, click on EXPORT and select "Fast Export DVD Compliant File" (NOT "Fast Export"). MF4 will create an Mpeg-2 file encoded to the same settings as your "Project Settings". Same as making the dvd.

If you then start a new project and use this compliant Mpeg2 video file disk burning will go very fast (provided you don't edit the video again). Your already aware of this, I repeat it for others to use when reading these posts.

The export feature was added in MF4 and this was a big improvement over MF3 to add manual control to create mpeg2 video.

I'd like to mention if I remember correctly that one of the older versions of MF, when you did join videos would produce a frame_based video. Versions after MF4 you can select your fielding. This was requested by many useers to add the fielding options into MF. Exactly because of the problems your now having.
I would double check all your videos created in MF4 that you joined. It's possilbe some may be "Frame_Based" and you never picked up on it. The video may look OK at frame based, but if you then put that same video into a program and render it as fielded video the results will be similar to what your experiencing now.
Check some of your videos from MF4 and make sure they are fielded and not frame based..
Definitely install Patch# 2 to MF6. After you install Patch#2 to MF6 I suggest doing some conversion from DV.avi to Mpeg2. You should like the results.

If the cause is MF6 original release then it should be fixed in Patch# 2 update.

Rager01,
I've used MF6+ to join files & create new videos. It does work on my computer. There was thing I did notice though was I needed to double check the fielding after making changes in the 2nd tab of the properties module.
After I did (or thought I did) assign lower field first it didn't take at first and reverted back to the default 'Frame Based".

After you JOIN any videos together if you right click on the one thumbnail that represents the joined videos and select "Media Properties" or click on the "I" Icon the pop-up screen will display the encoder settings for these joined videos. So you can double-check these settings before encoding. If the settings aren't correct then go back into the "Project Properties" and make the necessary changes.

Also, as a troubleshooting step you can import the dvd you created and extract the mpeg2 videos and check their properties to see if they are fielded correctly..

I've tried it again with MF6+ with patch2:
the result is the same. I cannot change field order because I've tried to connect 2 AVI files.
Maybe you can try it yourself and compare it with the quality when you let the 2 AVI files unconnected.
I think the effect of bad quality is not as powerful like when you have chosen the wrong field order, it is slightlier.

does nobody have the same problem?
I've tried it again. The same result, the first of the two connected videos is a little bit bad, but the second balks extremely.

I've been trying to reproduce your problem, however can not. Are your avi files, from DV camcorders, or some other source? As you know, AVI is a container, like a ZIP file contains different file formats. AVI can include such formats as DivX, Xvid, and mpeg4. All of those formats are very highly compressed, and meant for distribution, not editing.

I also believe that your problem lies with the field order being reversed. Also if you are having a language problem, here is the link to the German web-board. You may be able to explain clearer there...

I capture from a DV camcorder to AVI.
Then I cut the whole AVI into little pieces. The I change the project settings to 7000 kbps, lower field first (or no fields), Dolby Digital 2.0.
Then I make an DVD.
Then I copy the MPEG Files which FB6 plus created during the rendering from the FB6 directory to my own direcory.
These MPEG files I use for new projects. The field order of both files is the same.
When I make a new project then I import for instance 2 MPEG's and connect them. Then there is the problem after the program has made this new DVD.
In the project settings I have activated "no rendering of compatible MPEG files"

That doesn't sound like the correct method, the "No Fields" is very important. You either maintained the fielding or you didn't. It sounds like your de-interlacing one of the videos, (this is what happens when you select "No Fields") then when combing the mpegs back together(joining), introducting the fields back in, but the true fielding information is lost in the first render from avi to mpeg.

Sounds like your workflow needs adjustments. You must retain all the fielded information for any captured fielded video, if you don't then the video will not playback smoothly, it will shake/blur or jump when there is motion in the video.
Choosing 'No Fields" reduces the video from 60/50 pictures per second to 30/25 pictures per second. When this is done you lose the true motion in the video, it's lost and cannot be brought back without re-encoding the original video again using the proper fielding information.
