Ben 50fps video gerçekten seviyorum, ama ffmpeg benim için 50fps dönüştürmek yapamam.
720p çözünürlük benimle kesinlikle iyi, sadece daha fazla FPS'ye ihtiyacım var.
50i, uygun oynatıcılarda çok daha yumuşak görünüyor (örneğin, GOM Player videoyu deforme eder ve 50Hz'de oynatır. 25Hz video ile çok büyük fark.) ...
Geçerli komut satırım:
ffmpeg -i 00010.MTS -threads 3 -filter:v yadif -s "1280x720" -r 50 -b:v 20M output.avi
İşte daha fazla video detayı. Kaynak video Cannon HF10 AVCHD camcoder'dan.
ffmpeg -i 00010.MTS -threads 3 -filter:v yadif -s "1280x720" -r 50 -b:v 20M output.avi
