    http://www.youtube.com/watch?v=XLKG9D49D4Q The quality is fine, and it's pretty clear, but it's kind of laggy looking. And most important of all, whenever the camera moves around, you can see, like, lines, I can't explain it, but you can see something and it IS noticeable when the camera moves around. It's from an HD camera, and I saved the video in 60 fps. Does anyone know how to fix this? I plan on using this camera for skate videos, so I need to find out how to render videos without those lines, and how to make my videos play smoother. If it helps, the video was originally an hd m2ts file, and I saved it as a wmv file in sony vegas. Help is greatly appreciated. Thanks.

    The "lines" you mention are digital artefacts; if they're present on the original video, then you need to reduce the capture resolution and/or framerate. If not, then you need to change the way that you process the video. The "laginess" is also likely due to the camera struggling to keep up with the capture data rate.

    It might be 60fps when you uploaded it, but it's not 60fps when youtube re-encodes it. They only support up to 30 I think, so it will look more "jerky" than the version you uploaded when played locally on your PC before uploading

    If you're referring to the tearing, that's what happens when it's rendered in flash.

    It looks surprisingly good given the jerky fast pan camera movement.

    Can one think of a worse case source? Maybe with the lights off.

    The encoder deinterlacer and/or motion compensator can't keep up with your wild camera swings.

    What is the camera?

    Reduce the fps you are filming at,the camera tears like that cause it cant keep up the fps at 60.

    Sorry for the late reply, it's a Sony HDR CX100. Also, this video was taken with the same camera, http://www.youtube.com/watch?v=k04-ZEsvSRw This is when I rendered videos in 30 fps. It doesn't look as clear as with 60 fps, but it runs a lot smoother. I still think I'm doing something wrong with the rendering, because I've seen people with the same camera, and they can get it really clear, and not laggy looking, http://www.youtube.com/watch?v=1eTRTdwLemA I found that video on a forum, and he said that he was using the same camera that I use, so it's obvious that my camera has a lot higher potential for better quality, I just don't know how to do it.

    YouTube doesn't do 60fps.

    30fps shot native, or from 60fps with every other frame dropped, will be fine.

    30fps created from 60fps by blending frames is going to look blurred with movement.

    Cheers,
    David.

    Well, could anyone tell me HOW to do all those things? I'm not very good with rendering, so I have no clue what all the settings actually do, I just follow what people say. It'd be best to tell me the best rendering settings for Sony Vegas.

    You can't do anything about it if you use youtube , which will cut your video fps in 1/2 if you uploaded 60fps

    You can get a CCD camera which is immune to rolling shutter , or shoot very carefully with a CMOS camera (very slow pans)

    The render settings won't help what you are seeing on youtube , but better shooting technique and a better camera might

    Using a very wide angle lens helps the rolling shutter problem too. First, the circular "fish eye" distortion makes it less visible. Then the wide angle makes motions relatively smaller.

    There is a rolling shutter artifact removal option in the deshaker plugin for virtualdub. It may help.
