I need a good video compressor
Is there a specific format you are looking to compress to?
I use VirtualDub with the Xvid codec, but as mentioned, you need to be more specific about your needs.
Oh sorry forgot I posted this. I have an avi file that is too large,I want to make it a smaller avi file.
That's still not very specific. You merely pointed out the obvious. Here's an example of what I mean: 1) Would you like to add a title, transitions (fade, dissolve, etc), effects, filtering (contrast, sharpen, etc), background sound track? 2) Does it matter what video players it's compatible with? 3) Do you have a preference of codecs (Wmv, Dvix, Xvid, etc)? 4) Do you require something very easy to use? 5) Freeware only or are you looking to buy a video editor? 6) Does it matter how fast the program compresses? Windows Movie Maker 2 is free, comes with XP SP2, is easy to use and compresses fast but is restricted to Wmv, has terrible filters, and can't handle very complex projects (large files and/or lots of transitions, effects, etc). Truth be told it's one of the best editors to learn with though. If your system is robust enough to handle video editing easily it will make it a bit easier on Movie Maker but it was originally designed for photo slide show stuff so it can choke on some projects. VirtualDub, also free, will not add transitions, effects, and titles and requires demuxing (splitting) the audio/video to add background sound via mixing with another program like Audacity. It can be more complex to use but has extremely good filters and renders top notch image quality with Xvid, though using 2 Twopass compressions* which can take an hour and a half for a ten minute video. *Note that this is if you want THE best results in both video quality and file size. Of the consumer level video editors out there that I've tried I liked Adobe Premier Elements best due to it's filter quality, quality of compression, simplicity, and affordability. Compared to some other retail video editors it's slower at compressing but faster than VirtualDub. I actually get better image quality with VirtualDub and Xvid though.
