- DivX 1-pass : 4. Some of the very slight texture has vanished. Very good overall.
- XviD103 1-pass : 2. The blocks are very annoying, because you can see them move around when you play the video. The texture has also vanished a bit but much less.
- XviD110 1-pass : 2. Same as 1.0.3, very slightly better.
- DivX 2-pass : 3. The image is completely smooth, none of the texture has remained. Very few blocks.
- XviD103 2-pass : 2. More blocks, less texture but still a bit more than both DivX... Worse than 1-pass
- XviD110 2-pass : 2. Same as 1.0.3.
The key point here is that this frame doesn't get more bits in 2-pass mode, it gets less. All three 1-pass encodes look better.
For a better view of this picture you can switch to the ' Superposition' mode.
- DivX 1-pass : 3. The texture has vanished entirely. The overall feeling is preserved
- XviD103 1-pass : 3.5. The texture has been half obliterated. Much better than DivX.
- XviD110 1-pass : 3.5. Same as 1.0.3, with some visible blocks and a little less texture present.
- DivX 2-pass : 3. Very equivalent to 1-pass, it would seem that there is a little less texture present.
- XviD103 2-pass : 3.5. Same as above, very similar to 1-pass with a little less details
- XviD110 2-pass : 3.5. Same as 1.0.3.
The 2-pass seems to allocate slightly less bits than the 1-pass codecs. Overall the pictures are good, but all form of texture has vanished, specially with DivX.
- DivX 1-pass : 3. The texture has been obliterated again. The shape's edges are blurred a bit as well, with some artifacts.
- XviD103 1-pass : 3.5. Texture is a bit more present, artifacts as well, but not to the point of being annoying.
- XviD110 1-pass : 3.5. Same here, the texture seems a tiny bit more blurred.
- DivX 2-pass : 3. Hard to find any difference between 1-pass and 2-pass.
- XviD103 2-pass : 3.5. 2-pass seems a little bit more blurred, with a tiny bit less artifacts.
- XviD110 2-pass : 3.5.
Overall, the quality is good when watching the movie. 2-pass and 1-pass are very close, if not undistinguishable for each codec.
- DivX 1-pass : 4. A bit blurry and a bit blocky, but it plays well with the scene.
- XviD103 1-pass : 2. Can it get more blocky than this? I'm not sure. Hopefully the very fast motion hides it a bit, but not much
- XviD110 1-pass : 2. Same as 1.0.3.
- DivX 2-pass : 4. Blockiness and sharpness seems to be better here.
- XviD103 2-pass : 3.5. Still more blocky than DivX, the scene is now watchable. HArd to notice if you don't know about it.
- XviD110 2-pass : 3.5. Same as 1.0.3
For the first time we see a visible difference between the 2-pass and 1-pass encoders, and rightly so, since the bitrate on this scene is insanely high.
- DivX 1-pass : 3.5. A bit noisy, the scene plays out pretty well.
- XviD103 1-pass : 3. Blocks are at a level where they are annoying, but it is still very watchable.
- XviD110 1-pass : 3. Same as 1.0.3.
- DivX 2-pass : 3.5. The image looks a bit more blurred out than its 1-pass counterpart.
- XviD103 2-pass : 2. Noticeably worse than 1-pass, it becomes annoying.
- XviD110 2-pass : 1.5. This one is just horrendous. Not only it is blocky, but some blocks stand out pretty nastily.
Apart from DivX managing a pretty decent result here, XviD is very very blocky, and on this kind of picture it is very disturbing. XviD 1.1.0 2-pass is just a mess.
- DivX 1-pass : 2.5. While a bit blocky, the picture is blurred to a point where all form of texture or detail has just vanished.
- XviD103 1-pass : 1. Blocks are just filling the entire picture.
- XviD110 1-pass : 3. Noticeably better than 1.0.3 (at last!) the codec manages a good tradeoff between blocks and details.
- DivX 2-pass : 3. Sharpness has been regained from 1-pass, as well as a bit of texture.
- XviD103 2-pass : 4. While some blocks remains visible, they bring back with them a good chunk of the texture. Very decent.
- XviD110 2-pass : 4. Same as 1.0.3.
The difference against 1 and 2-passes is again pointed out here. Note that DivX maintain averages in both, XviD 1.0.3 was horrendous in 1-pass and very good in 2-pass. XviD 1.1.0 clearly shows better results than is predecessor for the very first time (but only in 1-pass mode).
- DivX 1-pass : 2. Again, detail has vanished (to a point where it's not obvious that it is raining).
- XviD103 1-pass : 2. Blocks are just omnipresent here again.
- XviD110 1-pass : 3. Again here better than its predecessor, unfortunately not by far.
- DivX 2-pass : 3. Some details are back (enough to see it's raining).
- XviD103 2-pass : 4. Still blocky, they are not annoying. The movie flows smoothly with it.
- XviD110 2-pass : 4. Same as 1.0.3.
Here the main motion is rain, and DivX just cuts it in 1-pass. XviD 2-pass doesn't look too good on a still, but the movie plays out quite well.
- DivX 1-pass : 3. The rain here is very contrasted so it didn't miss it. It is - hoever - quite blurred out.
- XviD103 1-pass : 2. Blocks are just omnipresent here again.
- XviD110 1-pass : 2. Not really any better than 1.0.3.
- DivX 2-pass : 3.5. The rain regains some sharpness.
- XviD103 2-pass : 4. Really feels crisp. Really good when viewing the movie.
- XviD110 2-pass : 4. Same as 1.0.3.
Here the main motion is rain, and DivX just cuts it in 1-pass. XviD 2-pass doesn't look too good on a still, but the movie plays out quite well.
