Hi there!
So i have this very strange problem with a 24 FPS movie, which i hope to get some assistance with from professionals over here ;)
The problem is that no matter how i try, i can’t get it (or a sample of it) to obey the set size (2 Pass Xvid) or bitrate (Single Pass Xvid) – after conversion it always turns out about 1/3 larger.
Usually i encode with TMPGEnc VMW 5 using Xvid 1.3.2 from xvid.org and default settings (naturally except bitrate or size). And i’ve done so numerous times even this autumn, so i’m really clueless of why this particular film doesn’t work.
Other software i’ve tried:
VirtualDubMode
AviDemux
MediaCoder
Xvid 1.3.1 & 1.2.2
In regards of Xvid config, i’ve tried so much (things i’ve never needed to touch before) to no avail:
Four CC, all options
Motion search precision, some options
Frame drop interval
Quantization, many min/max values from lots of forums
Xvid Home, Generic Standalone, Unrestricted profile
Quantization type, H.263 and MPEG
B-VOP, turning on/off
Reaction Delay Factor
Resolution change, progressive/interlaced, other FPS etc, etc.
I’ve also tried encoding on a fresh machine install (naturally not all of the above options), in case something was wrong with my particular setup, but the results are exactly the same: bitrate of the movie always comes out much higher then set. The same thing for 2 Pass encoding – set size is never met.
One more interesting observation: the movie does encode great to other formats and codecs (tried MPEG2 and WMV), but then i try to use that re-encoding to encode the size i want in Xvid, the problem persists. In other words, it actually persists through several encode iterations to different formats. I find it almost hard to believe myself...
So i’m turning to you, guys. Attached is a 20 second 500 frame clip from the movie, encoded in 2 Pass Xvid 1.3.2 (no sound). And if i try to re-encode it to a set bitrate or set a 2 Pass size, it doesn’t obey and gets much bigger (this particular clip was actually set to become 2048 Kb on a 2 Pass encoding). The full film behaves the same way, just on a larger scale.
Please, can someone try to encode it and say what the problem really is? :confused:
