Best way to lossless reduce the file size of video in raw format

fakie_flip · 09-06-2014, 09:02 PM

Here's the info I obtained for the Video. It's 4gb and 1 minute, 55 seconds long created by AmCap in Windows. I'd like to reduce it similar to flac, lossless. What's the best way to go about that?

Code:

Here is a list of lossless video codecs:
https://en.wikipedia.org/wiki/List_o..._compression_2

However, I don't think any of them will reduce the size of the video significantly. I would just use x264 in high quality mode, but there is a lossless mode too.

4G and only 2 MINUTES long????
