Different speed in CCE depending of movie-lenght?

[ekenet]

When i usually encode video that is about 10-20 minutes CCE has a speed of 1.144 or something. When i try to encode movies (80min+, haven't tested anything else than that) my speed stays at about 0.6. Does really the lengt of the movie/file has to do with the speed? The 10min video was a behind the scenes documentary and the 80min movie was of course the movie itself

The length of the movie should not have a major effect on the speed it encodes at. It will make a slight difference, but nothing like the speed discrepancies you are getting.

Are you doing anything to one encode that you are not doing to another? If you resize or use any other filtering than that can have a substantial impact on the speed.

Filters are most likely to blame, esp resizing filters can slow down encodes (and are all but necessary for all encodes). Also the video source format (RGB vs YUY2) makes a difference. As does the bitrate of your source/output file.

Try taking a file with a long runtime, cut it in half. Then encode the full file and the shorter file. Use the exact same settings for both files. Let us know what happens. (only need to encode for ~5min to stabilze the speeds no need to encode the whole video).

The only dirrerence between the two video-files is that on the bigger one I add subtitles. Perhaps that's the reason?
Vejita-sama, I'm not encoding one big file and one small file. I'm encoding vobs. Do you want me to cut down them?

You have 2 different sources...

1.) "10min video was a behind the scenes documentary"
2.) "80min movie"

Usually they dont use same specs for the main movie and extras (resolution, bitrate etc)... so the CCE would encode those with different speed... 8)
