Can anyone help me with this issue? I made a simple animation where the camera travels from one end of an object to the other. When rendered to an avi file the camera movement is choppy (quick pauses along its movement). Any suggestions? Thanks. |

This is hard to impossible to diagnose without some more info, I'm sorry to say. If you could include a screen grab, or better yet the animation (or a section of it) then it might give more clues as to what is happening.
Sounds like the keyframes for your camera are not smooth and regular, though that is just a guess. It could be though that your system is having trouble playing back the AVI, for instance, if it is a huge file (eg uncompressed, and on an older system).
Since this is about rendering an animation, time to repeat my advice - always render to a sequence of still frames, and not to an animation format. Then use a video application (or even tS itself by painting onto a flat plane, if need be) to render that sequence to an animated format like AVI or WMV or MPG.
The advantage is you can change your compression settings for the final video without the need to re-render from tS. You can also add and splice and cut and paste and re-render sections all without needing to re-render the whole thing.
Also by looking at the sequence of frames, you can see whether it is a playback issue, or a scene-set up issue. If the image sequence shows the pauses and changes in speed, it is something to do with the keyframing of the camera in the scene in tS. If the frames show smooth movement, then it is a playback issue (and you can experiment with different compression settings etc).
Posting the video itself is the best bet to letting people on the forum correctly diagnose the problem, so I would suggest doing that as the next step :)
HTH!

In the 'Render to File' window, also make sure that 'Field Rendering' is set to 'none' if your AVI is just for viewing on a PC.
The default tS setting isn't 'none'. |

Thanks so much for those ideas! I'm pretty new to this so it is all trial and error for me. I was rendering the animation uncompressed...I'm going to first try to experiment with compression to see if that works. The other ideas great too, and I appreciate you taking the time to respond to my question!:D Thanks again |

No problem, hopefully something here will help (that field setting is a good first thing to check). Unfortunately though it would be nice to give you one definitive answer, it is sometimes not possible to tell exactly what the problem (and so solution) is.
Keep us posted on results and I am sure we can keep coming up with possibilities until we get it solved!
Thanks,
Tom |

Following on from toddedwards reply, it's also likely that depending on the resolution being rendered too, uncompressed AVI could well be too much for his system to cope with on playback resulting in stuttering of the animation. That's not a definitive answer, but a definite possibility in the light of new evidence. |

That was my initial reaction too.. It would be hard to render a choppy video without doing it on purpose.. but playing back an uncompressed video from a standard drive is usually less than smooth, Ive seen those same symptoms a number of times, mainly now when I deal with High Def video playback as its so resource intensive. |

Also, are you switching to other applications during the render? Is your monitor set to switch to a screensaver after x amount of time?
When rendering, make sure you have your screensaver disabled, as well as power-save mode, and don't switch to other applications. As I recall, I ran into this type of problem before. If it's a long render, best thing to do may be to turn off the monitor.
