Yamaha Aventage RX-A1000 - Deinterlacing/Scaling Tests - Titles
Even though a video processor may be able detect the difference between video and film-based sources, such as shown in the previous photo, can it detect both of them at the same time? The reason this is important is that often, video titles (moving at 30 frames per second) are laid over film (which is moving at 24 frames per second). This can cause problems as the combination of both these elements can result in artifacts that make the titles look jagged or broken.
However, in this case, if the Yamaha Aventage RX-A1000 can detect the differences between the titles and the rest of the image, the titles should appear smooth.
As you can see in the real world example, the letters are smooth (the blurriness is due to the camera's shutter) and shows that the Yamaha Aventage RX-A1000 detects and shows a very stable scrolling title image.
Final Take
In addition to the tests shown in this gallery, what is not shown is how well the RX-A1000 detects and processes variations in film cadences. In this area, further tests revealed that the RX-A1000 showed good detection and processing of most test cadences, including the 3:2 film cadence.
On the other hand, testing also revealed that the RX-A1000 did not do as well in eliminating or minimizing video noise on source material where excessive video noise is present, and also did not extract enough image detail in the scaling process. Although troublesome artifacts, such as jagginess, moire, and film cadence jumpiness where actually addressed well, video noise reduction and detail enchancement came up short.
In addition, while the RX-A1000 can upscale 480i/480p to 1080p, it does not further upscale incoming 720p or 1080i signals to 1080p. In other words, if you have an incoming 720p or 1080i signal via Component or HDMI inputs, the output signal from the RX-A1000 is not processed further and will remain 720p or 1080i.
However, all the above being said, it must be noted that the RX-A1000 is an example of how much deinterlacing and scaling has improved in home theater receivers that offer this feature, especially in this price range.
Taking these test results, plus features, connectivity, and audio performance, into consideration, the RX-A1000 definitely deserves attention.
