Title: h.264 on a single frame?
Post by: polemon on 2012-05-05 00:11:33
I was discussing picture compression with a friend. He is quite experienced with audio/video coding, and at one time, he told me that h.264 produces better results, even when comparing it with JPEG. He even suggested, that when creating a video with just one frame, it compresses better than JPEG, this way it could be used as arbitrary picture compression.

Has anyone tried this? How could I do this, and later view that one frame?

Interesting link. But then I noticed that in his command line example, he's using a JPG as input to convert to h264.

That's like converting a MP3 to high bitrate AAC...

That's the whole idea behind WebP, using VP8 (patent-free) instead of H264 (patented).
