Hello.

I have started to work with animations and have problem with choppy video. Every 2-3 seconds it stops for a half second. But between the stops the video

runs very smoothly. On other computers it is the same accept one but we have not found out what the difference between the computers is.

Could it have something to do with different codecs? Direct X or something like that? Unfortunately I can not share the video.

I want it to work for others without any special setting on the computer. Any help or tip is very appreciated.

Spec:

23FPS

Standard Video and print format 4:3

Image size: 1080x810

Renderer: PhotoView

Video Compressor: Full Frames (Uncompressed)

Photoview Options: Final Render - Better

736 frames

32seconds

Size of video 1,7Gb.

AVI.

SolidWorks Premium 2012 x64 Ed.

SP1.0

Win 7 Pro, SP1 x64

HP Z400

Intel Xeon E312402@3.3GHz

8Gb Ram

Best regards

Josef

Using uncompressed images is like trying to run a high-speed slideshow, having to run through almost 2 gigs of video in a few seconds has to be very taxing for even a fast computer. You need to get the video compressed before it will work well. At that resolution you should be able to compress it down to 50MB without any degradation. The tough part is finding someone familiar with compressing video.

I would try re-recording the motion study and use one of the compressors to get the file to size.

I also remember having to do something with the key frames, either turning it off or setting it to 1

I would suspect that the computer simply cannot handle the data rate. I have a Dell Precision that did the same thing when I tried to play an uncompressed video of that size.

Now that I think about it, I think I had the same problem back in sw2010 and turning off key frames may have fixed the choppyness.

Thank you very much for your answers. I will try to use an other compression option.

Save as frames rather than an AVI and then compile and compress in a 3rd party software. You'll have better results that way.

Thank you Rob. I think that is the only way.

I tryed to choose the Microsoft Media 1 Compression but the result was very bad, even if I set the Compression Quality to 100%. Using the compression Intel YLUV resulted in the same as Uncompressed Frames. I think is strange that SolidWorks does not have an option between these compression alternatives, i.e very low quality or uncompressed, resulting in either bad quality or unplayable videos.

Thanks everyone for your input. I will render as uncompressed and have it compressed in a third party software.

Best Regards
