If you are seeing artifacts before you render, this is most likely due to your 'playback resolution'.
If you are viewing the artifacts in your 'program' panel, click on the flyout menu and choose 'playback resolution' then choose 'full' as in this picture:
In case you are looking at the video in the source monitor the same rule applies... click the flyout menu and choose 'playback resolution' and set it to full:
If you are seeing the artifacts after rendering or exporting, this can be a whole ton of other reasons I am too novice to begin to discuss, but one thing you can check is that the 'Use Maximum Render Quality' checkbox is checked at the bottom the Adobe Media Encoder dialogue.
Hope that helps!
On re-reading this, I realize you are having this problem in after effects... This is the Premiere forum. Try re-posting your question to the 'After Effects forum'.
The main difference is that AE and Premiere are NLE's and VLC and WMP are players.
If it looks ok in VLC i would not worry to much.
Thank you for your reply.
I'm sure it's not a problem of playback resolution. As I said, the problem is the same in Premiere, After Effects (full resolution) or Media Encoder.
So, the problem comes from the way the CS Suite decodes/reads the mpeg.
I'll try to upload a sample of the m2v so you guys can test it...
upload the same clip as you posted before if you can.
Just a few seconds should be fine.
I saw also, when importing for the first time the m2v file into Premire, AE or AME, I've got to wait some time, the message "media pending" is displayed, and after 30 sec I can see the footage loading and another message comes in overlay saying "rendu en cours" (in French, so 'rendering file') for a couple of seconds. This means that the Suite creates a sort of render of the file isnt it ?
Does it come in clear after waiting for it to come in ?
Let us know if you find somewhere to upload a sample.
Let us know the camera you used and what settings you shot it in.
Here you can download two test files :
Try ro read it in your favorite DVD software player or in WMP... Then import it in AE, Premiere or AME and look at the artefacts appearing.
For info those mpeg files were created from Beta Digit by a professional hardware mpeg encoder (Vizaro) at a good rate. We are specialized in DVD and Blu-ray authoring...
Thanks for your help !

Since this is not the original footage I wonder if the encoding went wrong.
It is odd that it plays better in VLC and Windows Media Player but not in Premiere.
I was able to notice the lines on the right hand side in VLC so something is wrong with the encoding I think. ( see picture 3 )
Here is what I noticed when bringing it into Premiere.
On Clip 2
It plays fine till 5:18
But on 5:19 the artifacts appear.
One thing I did notice that the whole video shows some thing wrong with the right side going down the whole side.
There are lines running up and down about 20 pixels wide or so.
Here is a screen cap at 400% ( Can be seen with VLC but not as bad )
Do you have the original copies of the video ?
At least you know its not just your computer.
Even you screen grabs in VLC show the lines to the right if you look hard you will see them.
My google search of the Sony Vizaro Encoder only brings back things from 2003. Maybe that encoder cant handle it anymore but I have no knowledge on that.
Wish I could help more.
Post the original clips if you have them.
Thank your for your support !
I do have the original material but it's not my goal to use it. In our workflow, we receive and encode movies from Beta Digit or HDCAM into mpeg2. From that file, we (motiondesigners) extract the parts we need to create our moving menus for the DVD. It's a lot easier, and lighter than capturing raw footage from the tapes.
For the menu, usually we used to work with DVD2AVI to convert the mpeg into whatever avi editable file. (no problem for the conversion since 2002, more than 1000 DVD titles made by our company)
But for an other client we were asking to create Press-Release DVD (for viewing purpose only, so not resale) for 40 full length movies. For this job, we only received DVD, sometimes BETA, but mostly DVDs. The client asked me to add also a watermark on top of it. So it's why I tried to achieve this job into Premiere. It worked very well, and very fast (new MacPro) except at those moment when the image is quite complicated.
So I'm a bit disappointed about the way Adobe Suite handles those files... Any chance to improve that ?
. It worked very well, and very fast (new MacPro) except at those moment when the image is quite complicated.
The thing is that those scenes dont look to be complicated. I still think its not Premiere but the footage your working with.
I just think that Premiere brings out the UGLY in those scenes.
I tried converting the footage but each time the artifacts are there.
Did you see how even on your screen grabs the image on the right side is messed up ?
yes I've seen this. This is typical when the image comes very precise, it often happens on tree or forest shots, artefacts are coming ... But, from the same file I used the freeware DVD2AVI to export the m2v into AVI and it's working very fine... so still disappointed by Adobe's interpretation of the file...
Let's try it : http://www.escapelab.com/temp/m2v/DVD2AVI.zip
(FYI, I set up this soft like this ; Video/Color Space/RGB and then export in the format you want)
Hey, I don't know if this would help but even when using Finalcut, and capturing certain DV footage with glitches or otherwise usually gives gurgled-chipmunk sounding audio problems or video artifacts as seen with your footage. Compressing the source files down to mp4/h.264 usually solves those problems. I know they're not the best formats to work with, but I try to max out the quality by turning up the kbps to the regular DV data rate( something around 30mbps I think ). Or do what I do and put it around 10mbps not that anyone notices the quality on DV.
