I'm making videos of my model stunt airplane with a Samsung camera that records pretty good 720P AVI files. It flies very fast so I have to have decent quality just to follow the action. I tried www.freevideojoiner.com and it's easy to use but it severely degrades the quality. Their home page says "Quickly join and without any quality loss... join AVI, WMV, MOV, MPEG, MPG files." But the output file is severely degraded. For example, I joined a 438 MB and a 330 MB AVI movie and the output file was a blurry 62 MB AVI. It wasn't worth using, especially after converting it to Flash for Youtube. Maybe I need a better program for that too.

Does anybody know of a good freeware program(s) that will do this without totally trashing my movies?

Thanks,
Rusty

Not a recommendation (I use a commercial program), but Freemake Video Converter and Machete Lite may be of interest:

You could try Avidemux it's free.

http://www.videohelp.com/tools/AviDemux

Open Avidemux, open your AVI, then "file" > "append" the other files.
Avidemux can then convert the AVI's to flv, mkv, mp4 or whatever.
I think you will get some loss in quality tho, because you're converting AVI to flv.
No guarantees. :)

Thanks for the replies. I expect to lose quality going from AVI to FLV, I understand that part. I'm just hoping to join AVI clips without that in itself causing a loss. I'll take a look at those programs. I had come across AviDemux earlier but it must have been an old page because I got the impression it wasn't compatible with Win7.

Thanks

That's why I keep an old Windows box around running XP. :)

You could also try Mpeg streamclip.

http://www.videohelp.com/tools/MPEG_StreamClip

I use it on my Mac, and it's awesome. There's a Windows version, but I never tried in Windows, don't know about Win7. & never tried to merge AVI.
so again . . . no guarantees. :)

What about Windows Movie Maker?
You already have it bundled with Windows
In the beginning there was the command line.

For reasons I don't recall, I never installed Windows Live Essentials except for Windows Live Photo gallery. I might as well go ahead and do it.

So far I've tried Machete-lite and it did the job fine. There's a black blip between the joined clips, but when I get time tomorrow I'm sure I can neaten that up. I downloaded and played with Windows Movie maker and it looks pretty useful too. I'm sure it will also join two videos, I just need to learn all of its features. I plan to try some others including VirtualDub.
I'm on the right track now, Thanks.

As regards uploading videos to YouTube (Post #1), I have only ever uploaded .mpg files and they do the rest.

I have found the following freeware program excellent for video conversion to Flash (and everything else).

Any Video Converter:

Okay thanks. I'll keep trying them in hopes one will have better output quality. I've seen some good clear videos on Youtube, but I'm not sure how they manage that.
