Hi, I'm using win7 and the latest version of avidemux. When I try to reduce the size (i.e. the "weight") of a movie my laptop heats up very much - 85-90 C°! and the file loses a lot of sharpness.... how can I improve?
Reencoding is a heavy computational load, if done on the CPU, it could warm up a lot. Cleaning the heatsink and the fan might help a bit (i have assumed you have an older laptop bc of win7).
Reducing size naturally reduce sharpness (due to loss of details). Anyway make sure that all post processing options are disabled in the preferences.
