How to import a high quality image/video showing software

Hi All,

I have filmed someone walking in front of my green screen and want to create an effect where the person walks across the screen but the background is a software product. I have tried a few different ways of capturing both a JPEG and say 5 seconds Quicktime footage but every time I import it to chromanator the quality is awful. The Icons and menu in the software are all fuzzy. If I run the .mov or JPEG outside of chromanator the quality of the video is good.

Any help would be appreciated.

Thanks

Could you upload an example JPEG so that we can test it out? Or email it to support@fxhome.com.

You are probably running in split field mode, which will appear to half the vertical resolution of your images for each field. This is correct if you are making it for TV, but if you are making something for your computer switch to progressive mode and make sure you deinterlace your video footage.

Hi

Thanks for the quick responses. I right-clicked the .mov in Chromanator and selected properties>scan method>progressive. The image does seem to have improved now in quality. Is progressive the best format for showing desktop footage? How do I deinterlace the current footage?

Many Thanks

The final footage is still grainy, both the person and the screen footage behind. What can I do to the original footage before I import it to make it better quality if anything? Many Thanks.

Have you tried exporting it out to see what the final result looks like, or using the preview render button. When you temp render the footage after performing an effect, such as colour difference, it renders at HALF resolution; so yes it will look grainy. I can assure you when you export, it uses FULL resolution and will look the same as your original footage. Let us know how you get on, or if there's still a quality issue post an image of your footage before, and whilst in Chromanator so we can see for ourselves smile

The footage is still poor quality so I'll get some screen shots. In the meantime what is the best output from chromanator for a movie to be embedded in FLash MX ? I tried "Quicktime" but the final file just skips but if I choose say "Quicktime DV" the movie plays fine but the screen shot in the background goes fuzzy and you can't make it out.

Thanks for all your help.

If you export uncompressed the file will skip, because your computer can't read the data off the file fast enough to play it smoothly. That's normal - the data is all there, though, so you can use it to continue editing.

OK, that makes sense. So even though that footage is jumping I could import it into my video editing package and then edit and export it from there and hopefully get a nice final video ?

That's correct. If computers were a bit faster and we could all afford massive hard discs, uncompressed would probably be the best option to store footage anyway.
