Looking for some pointers on how to minimize the blotchiness of animations using the PV360 option on the output of the animation wizard.
7.6 frames/sec is a pretty low frame rate which will give you chunky playback. I would start at 15 at a minimum. All of my animations are 24fps
Can you post a sample of the blotchiness you are referring to? Most likely, you are getting irradiance cache blotches and the only answer in PV360 to this is cranking up the render output settings.
It would help to see your output to determine the issue.
Looks like you're using the Microsoft video 1 codec?
Go to www.techsmith.com and download the tscc codec there under downloads if you want to stick with avi. Problem is whoever plays the file will need that tscc codec installed.
Or save your avi uncompressed and convert to mp4 format.
Or save as images and compile in another application and convert to mp4 format.
@Rob - Please forgive me, but I'm not all that familiar with how to work with codecs. I can certainly download it, but how do I "use" it?
Just "installed" it, but got a message implying that it may not have installed correctly. <shrug>
No need for codecs, if you do it via image sequences.
It's an exe file so just double click to install. Takes seconds
When you save your avi from SW it will be in the codec list to choose.
I agree with Paul. Image sequences are the way to go. The codec might be an easier more immediate fix for you though.
@Rob - Yes, it was that easy. But, it didn't show up in the list as an available codec....even after I rebooted. Not sure whats going on with that. I am running 64 bit if that's relevant.
@Paul - The customer is actually happy with that. I, however, am extremely dissapointed with the output. Since I'm trying to figure this out on his dime, perhaps his bar has been lowered considerably. ;-)
There is a specific 64 bit version of the codec.
It installed correctly (64 bit), but they want me to download Camtasia in order to use it.
Ah, didn't know that. Actually though their codecs are freely distributal so that seems odd. Well, you could install the free version of Camtasia to get it to work. Actually if you did that you could convert the avi to a bunch of formats as well.
Virtualdub may work well too? Never used it.
I agree with Rob...the microsoft codec ain't the greatest.
My recommendation is spend $30 on Quicktime pro and output your file as .tga image sequences. You can use quicktime pro to put the sequences to gether in a much better .mov file
I've used VirtualDub in the past for exactly this purpose (free) and it works very well. Try that before installing any Apple bloatware on your system, and I think you'll agree.
Here's a download link:
Lost ya on the bloatware comment...but anyway...are you saying that Virtual Dub will pull together image sequences?
Paul, the bloatware comment was in reference to Apple software I've had the displeasure of enduring on past systems (the abominable iTunes comes to mind). Some folks really like this stuff, but I've not enjoyed using it--at all--on Windows systems. Slow and unresponsive is often characteristic, in my experience. (And anyway, there is excellent free software available out there as alternatives.)
Going to try Jeffs suggestion now...
Stephen, another advantage to this approach is that you can patch in sections of animation at will. If you know your frame rate, you know exactly how many frames into an animation you are at any given time. If your animation renders perfectly, except when the decal is shown it's upside-down or reversed, you can simply re-render that segment of the animation and patch in the new/updated frames instead of having to redo the whole thing. Sometimes an animation will hang/stop part-way through, too, and you can keep the still images created along the way with the Targa method--not so with AVI output.
That reminds me--when stitching your individual frames together with software like VirtualDub, make sure your frame-rates match so it gets the speed of the animation correct (there are settings in the software). Basically, you want to match the frame-rate of what you rendered your animation out with SolidWorks or it will move to fast or slow.
Well, downloaded and installed the Camtasia software, output the file using the new codec, and now Camtasia and WMP say that the file is incompatible. Whiskey, Tango, Foxtrot....
Ya go with the image sequence option then. I just downloaded the VirtualDub and it works on my 64 bit windows 7 system. I also use the QuickTime Pro with good results.
I downloaded the Virtual Dub software, and it worked pretty well. The output to .avi is a little clunky however. My Solidworks animation was 10 seconds long and it generated 76 frames (I had it output to .tga) . Therefore, I prompted the VirtualDub software to sync 7.6 frames/second. It still seems to hesitate and/or skip on playback...and the file is huge (221mb). It does look 100% better (zero blotchiness) than what I was getting yesterday, but the clunkiness is a show stopper. Anything obvious that I'm missing?
Also, even with a higher frame-rate, some graphics cards/processors cannot keep up with the uncompressed nature of the targa frames at high frame-rates--so they end up looking "chunky" even at 30 fps. The trick is to figure out whether the chunky issue is a hardware limit or something in the animation, but in my experience, the targa method never produces chunky animations.
You can also save out to different AVI formats once you get your uncompressed first animation completed. So if it's to be viewed on the Internet, you don't want the full-size animation (giant file size) or it will take too long--and maybe even stutter/hang while streaming--or people won't have a good viewing experience with it.
Glad you found something that worked out.
@Jeff - Looks like the Virtual Dub download is going to do the trick. Much appreciated!
Thanks to all who took the time to respond and provide feedback. I have learned quite a bit about this process as a result. Kudos!
