Trying to make a weather report. The background images - movie is made. Now i need to record my body pointing to the correct spots on the map. So how do i do this? For example if i could record me on a green screen and remove the green all the while recording over top of the current weather map video ... It would work.

Am I on the right track? Any suggestions please

Hello Bill,

Yes, you are definitely on the right track -- you'll need to record yourself in front of a green screen, and bring that recording into Camtasia Studio so that you can remove the green. Also, TechSmith's User Assistance team has created a video tutorial specifically about how to use remove-a-color, including tips on how to set things up when recording yourself in front of a green screen. You can find that video here: https://www.techsmith.com/tutorial-camtasia-8-remove-color.html

I hope you find this information helpful, and please don't hesitate to get in touch if you have any further questions.
Cheers,

Hi there

I think the way they do it at a TV station is to have a monitor nearby that the weather person is able to look at and see themselves pointing at the assorted items on the screen.

In this case, I think you might need to somehow have some reference points on the wall or whatever your backdrop is that guide you where to point.

Cheers... Rick :)

Hello there,yes you are on the right track. However, the procedure is a little tricky, even when you have the proper equipment.

This is the typical workflow of a TV news weatherman. While standing in front of a green screen. They are watching themselves on another monitor with the green screen behind them already keyed out. The image or video that they are pointing too, is also playing on that monitor. So basically they watch themselves so they can see what  they are pointing at.

Also, the key to a good green screen shooting. Is very even lighting, no shadows behind you, no changes in the surrounding lighting at all. If you set up a green screen in your living room or someplace like that, and suddenly the sun came out from behind a cloud. That change in the lighting can make it more difficult to key out the green screen.

 I've actually had pretty good results standing in front of a green bed sheet that I attached to the wall with thumbtacks. Using nothing more than the light of day as my light source. This technique worked best on an overcast day. Plus the room that I did this in, had a window to the right and left of me and positioned behind me. There was also a window directly in front of. This setup gave me my even lighting. I also use more robust Chroma-keying software.

Good luck to you,Regards, Joe

Yes yes exactly what im trying to do Can camastisa or other software live record my body with removing the color key so the monitor is showing both me and the background video at the same time :). bill

Ok vidblaster does do the record live stream over existing video and remove the chroma key. Guess this not possible on camtasia. :(

Bill unfortunately Camtasia will not do that using live video and removing the green (Chroma Keying Live). Vid Blaster has those capabilities but requires some practice. My wife's cousin's husband works for a TV Station as a camera man and the setup they use is expensive but still requires some practice and like Joe said Marker Points etc. It would be nice if this was a feature in Camtasia Studio and also the ability to have the audio use ASIO for professional recording equipment.

I am hoping they update the next version of Camtasia Studio to the 64 Bit instead of the 32 Bit. It will run on a 64 Bit but uses 32 Bit. I hope this helps and if you do a Google search for live chroma keying setups you will find different site you can learn from and see how they put it all together. I hope this helps and thanks for posting and let us know how it turns out for you. Have a great day/night.

Hi Fred, I stumbled on to this thread trying to learn more about live chroma keying methods and noticed that you said your wife's cousin's husband works at a TV station. I know it's a long shot, but would you happen to know the software/computer hardware set up they use - or be able to find out? It would really mean a lot to an aspiring live tv camera man.

Dan they use some pretty expensive equipment and not much software like some would thing other than what comes with their Video Switcher Equipment. Al stations use different equipment pending on what they do. I would see if at all possible you should be able to request a Tour of a local TV Station if you just give them a cal. It is too much to list what all they use and how it is all setup. Let us know how this goes for you. Thanks for posting and asking and I hope you like my suggestion. Sorry I could not give more details but wanted to at least give an answer back. Have a great day/night.

Thanks for the link Rick. I used the Sparkocam with my Canon T4I DSLR Camera and also had a Logitech C92 and the C930 but had some crashing issues with that software. I think it could be a great software with some more improvements.

However Sparkocam is the only way I have found to make my Canon T4I work as a webcam. But for better quality I just record the video separate and import it into whatever software I am using for video.
