Rendered/Exported footage seems a little jerky/sluggish

[Steve2012]

Hi Guys,

I'm not really good with after effects. I have core2 quad 6600- 3 hard drives - raid 0-1 4g ram geforce 8600 graphics. AE 7 pro. I find that when I import footage that has been rendered out from pp2 to an AVI file, then import that into after effects and apply either magic bullet plug in effects or film magic pro effects to change the look of the video, then when I export the footage or render out, the footage looks great but the motion looks like crap. It slightly stutters and looks bad like I added some sort of effect to it.

Any ideas?

Thanks

Steve

Anyone?

What is your original source Progressive or interlaced? Are you rendering out to fields in AE?
Having the fields mix up can make your footage look jerky and stutter.

This would be one of a few things I can think of.

Hi Gary,


Thanks for your reply. The footage is progessive and when I export to an AVI file from PP2 it is fine. I then import that AVI into after effects, interpret the footage, then add magic bullet or film magic pro to change the look of the footage. When I export the footage out to an AVI file, the footage looks great(color wise) but there is a slight stutter or jerkyness to the footage. Same thing happens when I render out to AVI. What do you mean "rendering out to fields in after effects"? I don't understand what you mean unfortunately I am just stating to learn after effects.

Any help would be appreciated.

Thanks

Steve

Check your frame rates and that the footage was not jerky to begin with.

Frame rate is fine. Footage is normal. Renered out to AVI is fine. Import into after effects is where problem begins to show.

AE is set to "no fields" as default, if you didnt change that then dont worry about the field thing.
Also make sure your composition setting is set to the correct frame rate.

When you interpret your footage make sure the frame rate is set correctly as well and that fields is set to off. This should be all fine but check anyway.

Try rendering out to an uncompressed AVI. Some compressed avi codecs can be fussy.

Thanks Gary, I'll give that a try.
