Terratec Cinergy 600

I tried to capture from this card and in the encoding options i didn't choose anything(encoder).So i supposed the final result would be an avi file.Thats ok but the filesize was VERY BIG (160 GB) for two hours and a half video.Why did this happened?

you should at least give us some info about your ..

a) used driver

b) Capture application

d) Settings in your capt.Appl.

e) used codec.


Seems you did record just using an uncompressed Signal, means if you did set to YUY2 or even RGB24/32 without using any codec, then your final file will be mega big.

Use a capture codec, like mjpeg from PicVideo or my recommendation: HuffYUV ... which is almost lossless and results in big files but as it seems that you got enough disk space I wouldnt make any compromise ;)

Why does uncompressed video consume so much disk space?

Example: RGB colorspace. Full D1 resolution (720x576/25fps PAL, 720x480/29.97 NTSC).

Each pixel takes 24 bits (3 bytes) to define the color.

A single frame of NTSC video is 345,600 pixels, or 1,036,800 bytes. Multiply by 29.97 and you get 31,072,896 bytes per second for NTSC.

A single frame of PAL video is 414,720 pixels, or 1,244,160 bytes. Multiply by 25 and you get 31,104,000 bytes per second for PAL.

If you have not already done so, I strongly recommend reading both the Capture Guide and Capture FAQ. These are the top two threads in the Capture forum.
