Does the player resume at the last position when a disc is reloaded?
Yes, as long as BD-Java on the disc doesn't prevent it. According to the manual (Advanced Operations / Memory and Automatic Resume) the player will remember the stopping point of up to five discs when they are ejected or the player is powered off. Blu-ray discs with BD-Java cannot be resumed by the player automatically. You have to use the programming on the disc (if such exists) to set a bookmark or some other saved point. The studios are responsible for disc authoring issues that the player cannot override.
Note: If you don't want the disc position to be remembered, press Stop twice before ejecting the disc or turning off the player, or press Stop when the "resuming" message appears when the disc is loading.
Can output resolution and other controls be changed during playback?
Yes, most adjustments can be made on-the-fly without halting playback. The manual (Advanced Operations / Output Resolution) recommends ejecting the disc before changing resolutions. I don't know why this would be necessary, other than perhaps to minimize HDMI handshaking issues with touchy A/V receivers or displays. Changing output resolution during playback seems to work fine.
Does the player come with a Blu-ray calibration and evaluation disc?
Yes, the Spears & Munsil High-Definition Benchmark Blu-ray Edition. The manual is on-line: Spears & Munsil High-Definition Benchmark Blu-ray Edition User's Guide. Although the disc is not specific to OPPO players, OPPO assisted with its production. Many thanks!
Does the AVS HD 709 calibration disc work on this player?
Yes, both the AVCHD and HDMV versions of the AVS HD 709 calibration disc work on this player when burned onto DVD. I presume they work on burnable Blu-ray media also, but haven't tested it. The AVCHD version will also work when copied onto a USB device. See Is AVCHD video supported?
Does the player have a setup wizard?
Yes, see the manual (Installation / Setting Up the Player - Easy Setup Wizard). The Wizard runs the first time the player is turned on. If you prefer you can cancel it and make all your adjustments with the Setup menu directly. Of course, all the settings the Wizard makes can be changed manually later. See the manual text for a complete description. The Wizard steps are:
You can rerun the Wizard at any time. See How do I rerun the Setup Wizard?
- Primary output: HDMI or Component
- Output resolution: Auto, 1080p, 1080i, 720p, 480p/576p, 480i/576i, and Source Direct
- Aspect ratio: 4:3 vs 16:9 and their options. This is the shape of your display screen, not the aspect ratio of the discs you play. Use 16:9 Wide/Auto to have the player pillarbox 4:3 DVD titles.
- Audio setting: Advanced is for receivers supporting HDMI 1.3 and high bit-rate streamed audio formats. Compatible is for everyone else.
Does the player have an adjustable audio delay?
Yes, up to 200 milliseconds. See the manual (Setup Menu Options / Video Setup / A/V Sync). Note that this applies only to HDMI audio.
What writeable disc formats are supported?
See the manual (Important Information / Compatible Disc Types). Supported media formats include DVD+RW, DVD+R, DVD-RW and DVD-R. Dual-layer discs and CD-R/RW are also supported. Users report that BD-R and BD-RE work.
What are the Zoom features of the player?
The Zoom settings are described and illustrated in the manual (Advanced Operations / Zooming and Aspect Ratio Control). The Zoom levels are the same as on the OPPO 983H. Special features include:
The special Zoom settings are available only for HDMI. Component output uses a series of linear scaling steps.
- Underscan to compensate for displays with overscan.
- Vertical Stretch for Constant Image Height projectors.
- Full Screen for black bar haters. This works for both 4:3 and widescreen "Scope" titles. It zooms them just enough to eliminate the black bars on the sides or above and below. The image is trimmed on the edges but the aspect ratio is otherwise correct.Note that Full Screen is also the correct setting for zooming 4:3 letterboxed DVDs to full screen width.
Is there a bit-rate meter?
Yes, on the On-screen Display. It shows combined audio/video bit rate.
What is Demo Mode?
See the manual (Setup Menu Options / HDMI Options / Demo Mode). Demo Mode splits the screen vertically so that certain picture adjustments modify only one half of the screen. The effected controls are:
- Detail Enhancement
- Edge Enhancement
- Noise Reduction
Does the player support Deep Color?
Yes, see the manual (Setup Menu Options / HDMI Options / HDMI Deep Color). The entire display chain must be HDMI 1.3 or later, and must support Deep Color, which is an optional, not mandatory part of the HDMI 1.3 standard. Note that there are no Deep Color Blu-ray or DVD discs. There is no interpolation for Deep Color in the BDP-83 or its Anchor Bay ABT2010 video processor. The extra bits (color depth) available in the HDMI 1.3 Deep Color mode are used to preserve the precision of calculation. For example, any time color up-sampling, color space conversion, brightness and contrast adjustment, and other video processing is applied to the 8-bit/channel signal, the result can have fractions. In an 8-bit system the fractions are truncated, but in the Deep Color mode the fractions are preserved so the data delivered to the display is more accurate.
Some AVRs and displays give only lip service to 12 bit 4:2:2 or Deep Color 4:4:4 -- accepting the format as input but then immediately stripping off some or all of the low order bits prior to actually using that video stream. For example, many so-called Deep Color displays have physical display elements that can only handle up to 10 bits per component. The video processing engines inside the display feeding those display elements may also only do their math at 10 bits per component or even 8 bits.
Some Deep Color displays only actually implement Deep Color if you are feeding them a 1080p/24fps video stream -- i.e., not 1080p/50 or 1080p/60.
The result of all of this is that sometimes the only way to know what format is best for the HDMI connection is simply to try them all and see.
I hope people understand that Deep Color does not mean "deeper color" and that it is of (nearly?) negligible benefit when playing Blu-ray and DVD discs.
Deep Color does not make your blacks "blacker" or your reds "redder." The most you can get along those lines is a characteristic of your display, not of the disc or player.
Deep Color (which ought to be called "greater than 8-bit color") provides a finer gradation of shades between the colors encoded on the disc. It is conceivable that Deep Color might reduce banding in some images, although I never see banding in real films (as opposed to cheaply produced logos and fx screens). Someone could produce a test pattern demonstrating the effect with and without, but I haven't seen one yet.
The sad truth is that Blu-ray and DVD use the same rather limited 8-bit greyscale and color gamut.(This saves a lot of space and the eye is rather insensitive to color resolution anyway).
Using greater than 8-bit computations when doing Chroma Upsampling to restore full color resolution may do something to preserve a more accurate color image, but it is a very minor effect.
Does it come with an HDMI cable?
Yes. Length: 6ft. OPPO says:The cable has been tested and verified to support 1080p/60Hz with 36-bits Deep Color. We have not gone through the certification process for the HDMI 1.3 or Category 2 ratings.
Can subtitles be repositioned?
No, not at the moment. Maybe in the future.
Note: This is a feature the Constant Image Height users would like. It would shift subtitles out of the black bars and onto the image itself.
Anyone using full screen zoom could also benefit.
Why is it so difficult to shift subtitles on Blu-ray?
Although it is possible to shift subtitles on DVD, this is much more difficult on Blu-ray.
Subtitles are part of the "protected video path" which is cryptographically protected. A vendor would need permission and certified code from the BDA to break into the path and adjust the subtitles. So far, this support has not been forthcoming.
It is another consequence of Digital Rights Management.
Since subtitles occupy a tiny amount of disc space, the studios could easily provide alternative subtitle tracks shifted into the image area, but this practice has not been widely adopted. Immortal Beloved is a title that does it this way.
Are there custom output resolutions like 768 or 1024?
Can the front panel be turned off entirely?
Yes, as per the manual (Setup Menu Options / Device Setup / Dimmer Control). This can be done either from the remote or from the Setup menu. The power light remains on.
Does the player support 1080i50 Blu-ray sources?
Yes, 1080i50 content is supported. The output depends on the player resolution and TV System settings:
There is no 24p output available for this type of source. Obviously, your display must be capable of receiving a 50hz signal if you want to use one of those options. Frame rate conversion is handled by the ABT chip when Primary Output is set to HDMI, or by the decoder chip when Primary Output is set to Component. We do not have details on the frame rate conversion algorithms. See the List of Blu-ray movies authored in 1080i50.
- when resolution is Source Direct: 1080i50
- other resolution settings produce the expected result and the frame rate is determined by the TV System setting:
- when TV System is NTSC: 60hz
- when TV System is PAL or Multi: 50hz
What HDMI CEC functions does the player support?
OPPO says: The HDMI CEC controls are based off of the commands typically used by Sony. They are designed only for the most basic of functionality, such as Power On/Off and play controls. They are not designed to support advanced functions like Resolution or Setup.
