Real-time vs. after capture codecs

[mzidanic]

I can't answer your question about how a codec operates but I can confirm that I've had the same problem with the MPEG-4 V2 codec. I use it to export my edited video clips from Premiere before converting to VCD with TMPGenc. My original clips are 320x240 captured with a DC10+.

MPEG-4 V2 does a great job in bright images and fast moving scenes but is extemely blocky in dark areas as you also mention. I decided to use this codec because it compressed very well and was very fast compared to other codecs. A certain level of compression is necessary so that I can generate a single AVI file of a 75min clip to be under the 2GB limit. It's either that or get another Premiere plug-in to export mpeg-1 that really works. I tried EZ Cleaner and it took 24 hours on a 1hr clip and the audio got some strange noise added to it.

Does someone out there has any suggestions for an alternative to MPEG-4 V2?

a codec, or it's proper name "encoder/decoder" is a set of instructions for compression and decompresion

Lemme use Mpeg 1 Layer 3 audio (Mp3)

It contains a range of sounds the humna brain is not capable of hearing.

The codec tells the encoder to destory those ranges of sound and leave only what we can hear.

oh course, that's a simple explanation.
