Source files: 16Mbps AVCHD 1980x1080i .m2t files recorded By Sony HD camera.
A total of 9 clips (without transitions) - output file is 1min 30sec.
I will order formats by bitrate/file size
Format -- Resolution -- Extension -- Bitrate -- File Size
MPEG-2 BD -- 1440x1080 -- .mpg -- 24.83Mbps -- 298MB
MPEG-2 BD -- 1920x1080 -- .mpg -- 24.73Mbps -- 296MB
MPEG-2 HDV -- 1440x1080 -- .mpg -- 24.67Mbps -- 295MB
MPEG-2 HDV -- 1280x720 -- .mpg -- 19.46Mbps -- 234MB
H.264 AVCHD-24Mbps -- 1920x1080 -- .m2t -- 16.78Mbps -- 204MB
H.264 AVCHD -- 1440x1080 -- .m2t -- 16.77Mbps -- 198MB
H.264 AVCHD -- 1920x1080 -- .m2t -- 15.75Mbps -- 192MB
MPEG-4 Mobile phone -- 1280x720 -- .3G2 -- 9.00Mbps -- 106MB
MPEG-2 HQ DVD -- 720x480 -- .mpg -- 7.72Mbps -- 96MB
H.264 AVCHD -- 720x480 -- .m2t -- 6.24Mbps -- 79MB
Conclusion. I would definitely eliminate the following formats from the list. DVD 480p requires no explanation. 720 appeared jerky during the moving sceans.
MPEG-2 HDV -- 1280x720 -- .mpg -- 19.46Mbps -- 234MB
MPEG-4 Mobile phone -- 1280x720 -- .3G2 -- 9.00Mbps -- 106MB
MPEG-2 HQ DVD -- 720x480 -- .mpg -- 7.72Mbps -- 96MB
Below remaining formats appeared exactly the same on my 46" Samsung LCD HDTV. Funny how 1440 vs 1920 rendered higher bitrate and larger file.
If the videos are basically the same i then should go for the smallest file size and choose H.264 AVCHD 1920x1080 for Producing my future projects.
