Hi,
I'm new to the FX Home software, and I am experiencing some play back problems. My selected clip (once rendered ) is playing back very slow and jerky. Can any body help ??

I've moved this topic here, since it wasn't related to website support. Since you didn't specify which software you are using, I had to guess. If it isn't EffectsLab, let us know and I can move it again to the appropriate spot.

The playback issue could be a few different things. If the playback is very stuttered, where it will freeze for a while on one frame, then jump ahead to another, perhaps play a few frames, then freeze again, etc. - this is typical of uncompressed footage. If you rendered uncompressed, then you don't need to worry about this, as uncompressed footage isn't designed for playback. Once the footage is imported back into your video editor, all will be well. If you are trying to export a final version of your movie from EffectsLab, then you will want a different codec.

If the playback is just way too slow overall, then either the framerate or the scan method were incorrect when you set up your project.

Other more random weirdness could be related to the specific codec used. I assume here that when you mention the rendered footage, that you mean you rendered out of EffectsLab, to a new video file, as opposed to a preview render within EffectsLab.

Hi Axeman,
First of all THANKS for your advise.
Sorry if I didn't mention the software that I'm using, but its FX Home Effects Lab. I'm actually using a trial version, I presume its a trial version as my shots can't be exported into Windows Movie maker.
As for the footage, well, the original footage was shot at 1080p, then compressed using Emicsoft MTS converter into a format that Windows Movie maker would except, in this case It was MP4. The footage was then imported into FX Lab, then rendered, the required effect was just a basic machine gun blast, which worked fine, but the rendred footage wouldn't play back consistantly smoothly.
I realise that Windows Movie maker may be regarded as a fairly crude editing programme, and that I'm using a trial version of FX Lab, but as I said before I am starting out on this software for the first time.
THANKS

it sounds like mostly your issues can be sorted out once you get a bit more familiar with video formats and such, which can be a complicated and confusing topic when you are first getting started.

If you are working with EffectsLab and Movie Maker, then the format you want to stick with is .avi , which is compatible with both programs. Your EffectsLab problems are almost certainly down to the use of .mp4, which isn't designed to be an editing codec. If you convert the footage to .avi instead of .mp4, things should go much more smoothly for you. You can slo export from EffectsLab to .avi, and then the footage will still be compatible with WMM. In the Render menu, select the Render Settings, and you can cnahge the format from Quicktime (.mov) to DirectShow (.avi).The trial version will still allow you to do this.

As far as whether it is the trial version or not, if you didn't pay for it, then its probably the trial. If the rendered footage has a big watermark on it, then it is certainly the trial version.

Thanks Axeman, I'll take your advise and convert my 1080p footage to avi. I'll let you know how I get on.

All the Best
