The tutorial's .AVI files

[koenf1]

Hi,

I tried recording some things to show in public, but the problem is, as soon as I record something filesizes skyrocket on 1280 x 1024 resoltuions. I see in the tutorials, for a 25 minute .AVI file of 1280 x 1024 resolution, it has a filesize of only 70 Mb.

Is it possible to explain a bit more about the compression etc of these .AVI files?

TIA

Koen

Filesize has alot to do with the codec used. The tutorials use the techsmith codec which I beleive was designed specifically for video capture. Divx and xvid are popular codecs with good compression, movs are also quite nice, h264 codec is ment to be very good but I havent tried it myself.

Are you planning on showing the video yourself or is it to be sent to others to show?

If you're sending the video to others, one of the quicktime codecs would probably be best. As long as they have quicktime installed on their computer they'll be able to see it, whereas using an obscure AVI codec means they'll have to find it on the internet and download it first. H.264 and MPEG4 are both good for streaming over the internet due to low file sizes, and Sorensen 3 gives good quality video with pretty good compression as well.

If you're recording something to show on a screen in a lecture or something, you could just search for any codec with good compression and download it.

Thank you for the replies, first of all.

I'm a member of a modding team, which creates several F1 Seasons for the games F1 Challenge 99-02 ( EA Sports ) and rFactor ( ISI ) - you can see some examples in the link in my sig.

There are only a few modelers which achieve a certain level of quality, and it's not easy for new carmodelers to start and to keep on it. So, yes, the recordings I would do are for public.

I have CamTasia and TechSmith codec, but every time I want to compress it to Quicktime's .mov format, system freezes. Also when I want to play a .mov file, samething happens. Reinstalling didn't help.
That's why I'm searching for small .AVI files, but I'm not too trusted with video material and everything around it, as you may already have noticed . Ofcourse I do know DivX and XviD, but I'm not at all used to work with that stuff.

Thx
