Need a good capture codec

2 posts in this topic

Ok, HuffYUV is fast and lossless, but I need smaller sizes when I capture a live feed with Virtualdub. XVID is too slow (way too many dropped frames), Microsoft MPEG-4 v3 seems to work ok. Anything better? I need to capture 3hr long classes.

Sounds like a job for hardware encoding, but I presume that you are using a laptop so sticking a capture card is not so easy.

There are a few USB devices which can capture composite/audio, or you could use a network based camera. Even MiniDV camera (connected via Firewire) will do pretty good compression for you. At MiniDV you're looking at around 10G per hour.

Disk space is cheap now days, why not just grab and (re-)encode later? Of course the extreme hardware solution is to capture everything with a digi-camcorder to a *huge* memory stick.
