Can someone explain output file sizes ?

Post by Caveman »

Hello all

Just started to use HandBrake 1.3.3 and it really is a great piece of SW.
I don't want to report a bug, just want to get a better understanding.

Just did some transcoding test of a MPEG2 video from a DVD (576p25) to find the best settings.
Using the provided (unmodified) standard presets I get the following output file sizes:

Test_HB_Fast480p30.m4v 278.117 KB
Test_HB_Fast576p25.m4v 338.293 KB
Test_HB_Fast720p30.m4v 206.811 KB
Test_HB_Fast1080p30.m4v 251.802 KB

I was expecting that Fast576p25 would give me the smallest output since it is closest to the source format.
But it produces the largest file !?
Also I'm surprised that the presets with higher frame rate produce smaller files.
Can someone explain why file sizes turn out this way ?

With these results I would go with the Fast720p30 preset since it seems to produce the smallest output.
Is there a risk of loosing details or quality using the Fast720p30 preset ?
Which preset should I use if I want to preserve maximum quality ?
From looking at the outputs I don't see a difference.

Thanks

The higher resolution presets are configured for sources with those resolutions (or higher), so they have a lower quality target (higher RF).

Happy New Year to everyone !

Thanks rollin_eng for pointing me to the log-files.
I realized that I used VeryFast720p30 instead of Fast720p30 :oops:
Sorry for that.

Correct output file sizes are:
Test_HB_Fast480p30.m4v 278.117 KB
Test_HB_Fast576p25.m4v 338.291 KB
Test_HB_Fast720p30.m4v 292.774 KB
Test_HB_Fast1080p30.m4v 251.802 KB

Thanks mduell for the quality information.
I modified the RF parameter in the last two presets to be euqal to the first two presets (RF = 20).
That gave me the following output file sizes:
Test_HB_Fast720p30_mod_RF20.m4v 338.291 KB
Test_HB_Fast1080p30_mod_RF20.m4v 338.293 KB

So, everything all right and consistent. Sorry for the false alarm.
And the Fast576p25 preset matches the source I have quite well.
Or should I do something about deinterlacing/telecline as suggested in the log file ?

Here is my Source-Scan Logfile:
