View Full Version : Two pass encoding in real-time and max. resolution?

Hello!

I have two theoretical questions to MPEg4 codecs (such as XVID/Divx etc.).

1. Can I use two pass encoding in real-time video capture? Or this is principled impossible, real-time only with one pass?

2. Have the mpeg4 encoders a limit in the max. resolution?
I read an article about a dual-HD resolution video (2x1920x1080 the resolution-and this can be get higher in the future). Can xvid/divx handle these extreme resolutions?



Thanks!

How do you propose to run two passes in real-time, when the first pass must be finished before starting the second?

ok, my first question was fatuous.

but, the second?

Look at the far right column. It answers your question.

That wikipedia entry is for H.264/MPEG-4 AVC, not MPEG-4 ASP.
