I
have a question about video size. When I download the file from GoToWebinar - it's 280mb - I bring it into Camtasia and cut OUT several sections and do not add any animations or anything - yet when I export it it's almost TWO gigabytes in size. it's for replay on a web page - what should I have my export settings set to?

I searched the camtasia forum and based on what I found I set the settings to the following -(see image)

What should the settings be please?

Questions for you: How long is your video/presentation? What are the dimensions of the original recording (1080/720/480, etc) ? Is CALVC your only option for entropy? What's the size when you use their automatic settings? 

Generally, webinar recordings are super compressed so when you encode it, the software is dumping a lot of additional data into the recording to fill in the blanks...so to speak...

I'd suggest you do the following:

1. Drop the frame rate to 24 or 15. If your webinar is just people talking or people talking as they walk through some sort of slide deck, then you really don't need 30 fps. I doubt the original recording was at 30 fps to begin with. Same goes for software demos--no one needs to see the mouse move at 30 fps haha.  I always think of producing webinar recordings as "lipstick on a pig"... I can cut out stuff they don't need and add a few callouts but at the end of the day, you're generally dealing with a highly compressed live recording. 

2. If you can get away with it, drop the size to 720 or even 480. This will save you a lot of space. If your recording is of a slide deck or a software demo with a lot of small text, you'll want to stick with 1080p (assuming the original recording is a 1080p). 

3. Make the video dimensions and frame rate as close as possible to the original. If the recording is 15 fps. render at that frame rate. If you recorded it at 720p, drop the project to 720p. Making either of these higher than the original recording isn't going to improve quality but it will definitely add to the file size.

Simple answer: Upload the 2GB file to YouTube or Vimeo. They will compress it and resize it to six sizes and host it for you. Problem solved. You can even download their compressed versions for distribution elsewhere, but you seldom want to host web video yourself.

Years ago we played with all the options to try to avoid YouTube compressing our vids. These days they do a better job than we can possibly do (Google algorithms and server farms). Let them do it.

Hahaha yeah or that. But if you work at an organization like mine that makes you host all our own videos and you don't want to mess around too much with the settings, you could also use something like Adobe Media Encoder, which will even tell you the approximate new file size before exporting.

 Although in hindsight, I could have uploaded to my paid Vimeo account and then downloaded the reduced file-size version...hmmm

There is a free software Handbrake that helps to reduce file size drastically with good results. Just put it in and press start en see what's coming out.....
