Ok, so I am editing this movie that me and my friends are making and there is a scene where a ton of stuff explodes. I use apple imovie to edit and I exported only the explosion scene and put it into effectslab to make the effects. I completed the scene and it has a total of 18 effects between the explosions, the smoke, and the fire. I finished everything that needed editing in the scene and rendered it but when the render finished and I looked at it in quicktime the scene goes about twice as fast as it should go. Also, in each frame, as the characters move, they are unfocused and a double of them appears from the last frame so that in each frame you can still see the position of the character from the last frame. Does anyone know what's going on?

Check out this article in the Knowledgebase.

For further support questions, check out the Knowledgebase in the Support Center. It has very intuitive and easy navigation to the articles.

For example, to find this article, I clicked the following links: Support>Knowledgebase>Software>Effectslab Pro>Render/Export. From there, the third article address speed changes in exported videos.

Thanks, but I am still confused. How can i tell what the framerate and width/length of my clip are before i put it into effectslab so that I can set the correct settings? Also, is the problem with the frames doubling up on each other just because the framerate is incorrect?

To make sure that the project settings are correct to your clip that you are adding effects to...

Instead of opening a blank timeline select the video clip and the program will automatically match the settings.

I think the doubling up of frames is an interlacing issue if i remember correctly.

I just tried re-rendering the clip and I changed the framerate from what it was (25 FPS) to 30 FPS because the videos I have done in the past using effect lab have been rendered at 30FPS but the result was exactly the same. Also, the clips sound only starts about half way through and then continues for about 3 seconds after the clip has ended. During this time the last frame just stays frozen on the screen. Any other suggestions? Would it make any difference if I tried exporting without sound?

How do I fix an interlacing issue? And is there any way to fix the video setting without restarting the project? I have already edited the entire thing and it took about 6 hours.

You fix an interlacing issue by using the correct settings at each stage during the process. I know that sounds like a useless answer, but its the best one I can give. You need to determine the interlace (or progressive) settings your camera uses, and stick with them throughout the entire editing process to avoid issues. Interlacing is a tremendous pain in the neck, but its how video works so we are forced to deal with it.

You cannot change the project settings once the project is created in EffectsLab. This is another reason it is important to get the settings correct. However, in order to not lose all the work you have done, please see this knowledgebase article. As detailed there, you can use presets to transfer all the work you did to a project with the correct settings, so you don't have to start over from scratch.

Its worth visiting that page to make sure you have the latest version of EffectsLab installed.

As far as the sound glitch thing, what render settings and codec are you using? Does it make a difference if you try a different codec, or if you try different render settings?

Ok, that is helpful, but how do I find out exactly what the correct setting are for the start of a new project?

Yeah, that is probably the easiest way. Also, after selecting the movie, you might want to make a note of the settings it selects, so you will know the right ones in the future.
