Does anyone have Sony EV-S9000E ?
Does anyone have Sony EV-S9000E ? I have a question about the "capture window", about how the image is shifted 8-16 pixels upwards and there's also some chroma errors in the top of the image spanning in the 8-16px range. I'm wondering whether this is normal behavior or something gone wrong in my unit. It's been always like this as long as I've had it.

For clarification, this is the Sony EV-S9000E PAL HI8 VCR. It's sometimes referred to as one of the best consumer Hi8 VCRs around.
There's some discussion of it here: http://forum.videohelp.com/threads/3...capturing-NTSC I would agree with the assessment given by another poster in that thread -- many higher-end Sony Hi8 cameras are known to give exceptional (and accurate) playback results, compared against even the best VTRs. It all comes back to the model of the unit, and the condition. What you describe is sometimes normal behavior, on other types of equipment. For example, The Elite Video BVP4+ proc amp has some slight chroma noise on the outer edges of the corrected picture, although well into the overscan -- and it can often be tweaked out of frame with screwdriver adjustments. Certain DVD recorders shift a few pixels, too. |
My bet is on the normal behavior but confirmation never does harm. It has been serviced 2-3 times, TBC unit redone, calibrated etc and shift's remain.
About VTR Vs Camera. I have EV-S2000 and EV-S9000 PAL VTRs and they both outperform the cameras I've used. EV-S9000 has seen a lot of use and the "out of box" chroma looks uglier than some. But after my usual denoising chain, the cleaned picture is better than video from camera that's been through the same procedure. Cameras produce DV-compressed video, which sometimes is clipped in the highlights because there's no possibility to adjust the 'procamp' before compression. From VTR lossless capture is possible. One could argue that camera has analog outputs too - which is true. I haven't really tested this ever so I can't comment on the quality of that option. Other thing to remember is that EV-S9000 is professional "audio device", it records PCM audio. In every case I've tested the same material in both camera and EV-S9000, the latter has clearly better audio performance. Even when the audio is "normal" mono/stereo track. And the usability. Going thru hundreds of tapes using camera - I'd go mad. :) There's been cases where I've needed camera to get some tapes with bad tracking to work. EV-S9000 was changing to PCM mode all the time and that produced horrible noise. I didn't have EV-S2000 at that time which might've worked too due to lack of it's PCM support. |
Am I correct in that this issue you're seeing is completely in the overscan? If so, I'd just look to mask it, and not get too caught up in the imperfections. The fact that you're even noticing puts you ahead of even some of the most skilled broadcasters and TV show editors, who seem to get sloppier every year. If I see another commercial stutter across my screen (broadcast with reversed interlaced!), I think I'm going to scream. And I don't mean the local overdubs, but the national feed national commercials!
Good work. :) |

Yeah, it's in the overscan. I'm a bit anal at times. :p Sample included from 2000/9000 (originally PNG, converted by forum software to JPG).
And thanks. |

That's easy to fix! I am using only a simple approximation here, in some cases certain colors with texture will look odd.
Code:
#Fix Sony 9000 Digital8 video |
That works great! :) Approximation is a lot better than the way-off colors before. I'm too tired now to think what exactly is happening in this script but I'll look at it in more depth tomorrow. Thanks.
PS. do you have anything relating to VHS/etc color bleed? I've tried a few scripts utilizing aWarpShap but so far they've introduced some artifacts at times which cannot be tolerared (colorshift is under control). |
The problem is that part of the color is missing. Whenever you see something greenish, think "Pb=0", in other words one of the color channels is always zero. So I just approximate it and it looks ok. I'd like to know more about this problem. Would you be willing to record a test video to a blank tape for me?
It would be really helpful if you knew how to turn an avisynth script into a video and record it to the VTR somehow. Also let me know what capture device you use (it would be great if you have a computer capture card). There's some other problems with the video, I can fix those too (the greyish line on the left). I love this, keep the weird little problems coming :) |

To be clear, as far as I can see XR supports "date and time" info embedded like DV-formats etc, and not timecode like professional equipment? |
