I am using Reclock to get smooth playback of my movies on the TV, but I got a problem. The problem is that when there is a frame skip in the movie itself, like when there is bad Inverse Telecine, Reclock sometimes looses the video sync and the picture starts to stutter. I have found out that this is dependant on which decoder and renderer you use. If you use ffdshow instead of the divx 3.11 codec there is a greater chance that the picture starts to stutter. I made the quality tests with a clip from a scene that is dimly lit. divx and xvid have problems with these kinds of scenes and you can clearly see blocks moving on the walls in the background. I also tested it with an underwater scene that has light shining down into the water. The four renderers I have tested are:
Old renderer: This is the renderer Media Player 6.4 uses. It has good picture quality and uses the overlay settings on your video card. It is pretty good at handling stutters in movies.
Overlay Mixer: I couldn’t find any differences quality wise between Overlay Mixer and Old renderer, but it isn't as good at handling stutters in movies.
VMR7: This renderer was only accessible through Media Player Classic. It also uses the video cards overlay settings and has about the same quality as the two renderers above. I couldn't see a difference. It is also pretty good at handling stutters in movies, maybe not as good as old renderer.
VMR9: This renderer seems really good at handling stutters in movies. I haven't tried it that much yet, but it seems to handle stutters much better than the other renderers. The problem I have with this renderer is that the quality isn't that good. In the scene I was using to test the quality, the block on the wall was much more apparent. Instead of gradient smooth transitions of colors on objects, it was visible changes in colors. This isn't apparent in scenes in broad daylight, but in dimly lit scenes you can clearly see it. The underwater scene didn't look good with any of the renderers, but it looked horrible with VMR9. VMR9 doesn't use the Overlay settings so it is hard to change the brightness and contrast settings. The latest release of Zoomplayer has an option to change these settings that is a little buggy, but works. But I couldn't get the same picture quality as the other renderers even if I changed the brightness and contrast settings.
Has someone found out a way to improve the picture quality of the VMR9 renderer? I would really want to use it because it solves my problem with stuttering movies.
