Greetings,

I am new here, and have been playing with EffectsLab Pro (Demo) for a couple days. Now, I have some questions. Oddly enough, I got most of the more advanced features. It's a little problem I am having.

Ok, I am making a lightsaber battle. Doing the 4-point effect and masking frame per frame isn't a problem. That I can do with litle effort other than time spent doing it. The problem involves the timeline.

Occasionally (as you would expect with an digital video) one frame is duplicated. No biggie, just step through it and move to the next actual frame right? Well, let's say frame 6 is a duplicate of 5, so 5 and 7 have actual effects. Frame 6 seems to "interpolate" the position of the blade between 5 and 7. I have no real problem with this except that when the video is played back (within the program), it includes this extra frame, and you can actually see the physical prop with the effect in a different position. How do I fix that?

Second problem is that when I render it to file, it plays back only a single frame and it's done. How do I get it to render the whole movie?

First Problem: When you create the project you will need to select progressive under scan method. That should fix your problem.

Second Problem: Go to the Render menu and select Auto-in-out frames.

For the first issue, it sounds like the double-frame only happens occasionally, not on every frame, correct? If so, clicking once inside the shape of the lightsaber on those frames will create a keyframe for its position, to override the tweening that is throwing the effect out of place. The program is always going to transition between one keyframe and the next, so the way to stop this from moving the effect to the wrong position is to create a keyframe on those frames as well.

The rendering issue is likely related to the codec your footage is in. I'm guessing you are using some sort of mpeg or h.264 codec, none of which are designed or intended for editing. If you can confirm what codec you are using, we can proceed from there. If its just an in and out point issue, like TURpodcast mentioned, then following his instructions should get you up and running.

Ok, TURpodcast, both your suggestions worked. Thanks a ton.

As for the video type and encoding...my "stock" was a goofy stick fight movie I pulled off the internet just to play around with, and is in avi format. I already had it set to progressive so I guess the duplicate frames were already there. Second, I render it back to avi using "Uncompressed" because quite frankly, I never understood codecs or how to select an appropriate one.

Any tips will be appreciated. And also, what is the best way to film digital video for edit? Hopefully something that doesn't blurr motion very much. Sometimes with the dumb vidcam I have, simply swinging a stick around at a moderate speed will render the stick invisible in the frames.

Well, to stop things from blurring, you just need to manually set the shutter speed on your camera while filming to a faster speed, but keep in mind that film almost always uses the slowest shutter speed possible, and if you remove all the blur, it will make the footage look even more like video, and less like a movie. In case that is an issue. A better option that I've found is to color the blades of your lightsword props (I use colored duct tape, matching the color of the blade I'll eventually add), and make sure you have plenty of light in the scene, which will help the blade to remain visible, even when it is blurred heavily from the motion.

Ok. What I have is something like the one linked below, and it doesn't come with that level of control. *cough*

Since I don't know what I'm looking for, can you tell me what the best thing to buy at the site above is (under 1k if possible)?
