Video Stutter/Jitter

Post by ddustin »

Greetings,

We purchased DVD Movie factory to take our rendered animation files and place them on DVD.

The test project exeriences jittering/stuttering of the playback, regardless of the player (set top, or PC player) used.

We also have Adobe Encore and tested the same files. Encore produced the video, and it played smoothly. The video quality was not quite as good with the Encore version as the Ulead but there was no jitter.

Our pipeline is as follows:
1. We render our frames from 3ds Max to .tga
2. Frames are brought into Adobe After Effects and exported as uncompressed .mov
3. .mov are imported as video files.

I have tried leaving the "Do not convert compliant MPEG files" box checked and un-checked. As well as the "Two Pass Conversion" check box.

Is there a different format I should export the files from After Effects in?

My system is AMD 64 X2 4600+, with 2 Gb RAM.

We need to get this addressed or the software will not be usable.

Thanks in advance for your help.

David,

First make sure the frame rate of your animation video matches the DVD TV standard of your DMF project. And render the same frame size.
I have tried leaving the "Do not convert compliant MPEG files" box checked and un-checked.
That option is only for material that is already DVD compliant. But you're feeding it uncompressed mov which needs to be converted/encoded to MPEG2 for DVD anyway, regardless of that setting.

I've never used any mov clips, so I can't provide tips based on experience with mov files.
Your DMF project will complete quickly and easily if you feed it clips already encoded in DVD-compliant MPEG2 (assuming you can do that with your Adobe software, instead of exporting uncompressed mov), setting the "Do not convert" option mentioned above. DMF will then just need to render/encode the menus. The quality of the animation will then be unchanged by DMF.
Or you can try another format (like a DV AVI) and compare the MPEG2 results of DMF to the encoding of the other software.

Thanks for the reply.

That is exactly what I tried... using .m2v and it worked great.

Some of our industrial visualizations have a lot of geometric shapes which can exibit moire artifacts along the edges.

Rendering them with the right filters and then processing them correctly makes all the difference in the world.

Thanks again.
