Hello again,
revisiting my old thread to share my more recent lessons-learned and to reply to the registered members who PM'ed me throughout the past years. No real surprise here, my current S-/VHS setup as follows: JVC HR-S9600 {S-video/RCA audio} > Panasonic DMR-EH495 {HDMI} > HDMI-Splitter {HDMI} > Intensity Shuttle {Thunderbolt} > Mac I am using the same setup for Laserdisc, replacing the JVC with a Pioneer CLD-D925, sticking to S-video because the composite video out (RCA, Scart) of the D925 is fed with a merged Y/C signal anyway. On the HR-S9600 Digital 3R is turned OFF per suggestion in various forum threads, and TBC is left ON. On the D925 the HQ-circuit function is turned OFF as it softens the video unnecessarily. In addition, I am running the video/audio signal of the EH495 to a small multiformat TV that supports S-video through Scart and also offers seperate S-video and RCA connectors for testing purposes. It's easier to read and configure the device settings that way, too. So far the Intensity Shuttle has been a hassle-free experience both in terms of the hardware and the software suite containing the apps/drivers (i.e. Desktop Video 12.4.2 running on macOS 12.6.5). The abovementioned S-/VHS setup works for PAL sources whereas the LD setup also allows for NTSC (NTSC 3.58, not PAL-60) because the D925 and the EH495 both support it. Lessons learned: - The tv format (PAL/NTSC) must be set accordingly in both software applications, Desktop Video (where you select it in the source settings) and Media Express (where you have to select the tv format in project specs), otherwise you'll end up with a black capture screen. - Changing the tv format on the EH495 resets the HDMI settings to AUTO so you need to adjust them again to 576i/480i for use with the Intensity Shuttle. - I couldn't catch a difference between setting the JVC to B.E.S.T. OFF/Picture Control NORM or B.E.S.T. ON/Picture Control AUTO. With the latter option however B.E.S.T. automatically kicked in on some tapes that otherwise failed to display the video for a couple seconds, so that's nice. Your mileage may vary...:wink2: - The NR function of the EH495 (remote press Display > Video > NR ON) improved the flickering I encountered with various Laserdisc. - At this point in time, the Intensity Shuttle is apparently discontinued but still supported for Intel based Macs according to Blackmagic Design's support documents. Well, I guess nowadays there's already an overwhelming ammount of user feedback on the benefits of the abovementioned capture method (DMR+Intensity Shuttle). So, drawbacks? While the Media Express capture software offers the option to "stop capture if dropped frames are detected" I see no way to confirm this since it never stopped on me. Other than that? Cables, adapters... any of which can fail, too... :D |

The B.E.S.T function adjust video EQ and various things depending on the output from the tape (haven't found exact specifics for the newer JVCs though) so the degree of difference between it on/off is going to depend a bit on the tape.

It's more the analog part of the processing that is turned down as the digital noise reduction from the TBC/DNR function is still pretty active. Using the EDIT setting is going have a more pronounced difference on tapes where the video signal is weak. |

Laserdisc sample as follows: D925 set to NTSC 3.58; EH495 set to NTSC. Media Express settings: 525i59.94 NTSC, QuickTime Uncompressed 8-bit YUV. S-VID.mov = S-video S-VID_NR.mov = S-video, EH495 NR ON S-VID_NR_HQ.mov = S-video, EH495 NR ON, D925 HQ ON COMP.mov = Composite COMP_NR.mov = Composite, EH495 NR ON COMP_NR_HQ.mov = Composite, EH495 NR ON, D925 HQ ON (I forgot to mute the samples for composite video.) |

You might try using your JVC VCR in passthrough mode to convert the composite signal to S-Video and see if that looks better than using the S-Video from the D925 directly. |

I’m totally okay with that because it was the best choice for PAL & NTSC playback in the EU back when I purchased it in the 90s. There are certainly more capable LD players for NTSC, there might be for PAL, but given the fact that I capture my LD library for fun, not preservation, I don’t really mind. Quote:
Feel free to check out the samples though. I am interested in everyone’s opinion because I’m certainly not trained to spot slight nuances in colors or sharpness, and so forth. |

@traal: Yeah, I’ve read through most if not all those LDDB forum threads throughout the years. Even checked out the service manual out of curiously. But back on topic. i.e. capture workflow on Macs, which of the six samples above yields the best quality in your opinion?

The attention span and patience is getting shorter and shorter nowadays, I think the OP miss-understood my point in my previous post, I never asked to capture LD over S-Video and convert it back to composite, that would be totally wrong and un-necessary, I asked for two samples:
1- LD -> Composite -> DMR -> HDMI (testing DMR comb filter) 2- LD -> S-Video -> DMR -> HDMI (testing LD comb filter) No need to post six samples. I'm pretty sure the comb filter in the DMR is far superior to the one in LD but I though I would confirm with real samples. So which two out of the six samples are the ones we're looking for? doesn't matter what setting for DNR as long as test conditions and setting are exactly the same for both samples as I outlined in my previous post. Not sure what a comb filter is? here is a nice write up. Edit mode in the VCR means it is used as a player only, feeding an editing deck, Capturing is no different than this task. |

S-VID.mov = LD -> S-Video -> DMR -> HDMI S-VID_NR.mov = LD -> S-Video -> DMR -> HDMI + EH495 NR ON S-VID_NR_HQ.mov = LD -> S-Video -> DMR -> HDMI + EH495 NR ON, D925 HQ ON COMP.mov = LD -> Composite -> DMR -> HDMI COMP_NR.mov = LD -> Composite -> DMR -> HDMI + EH495 NR ON COMP_NR_HQ.mov = LD -> Composite -> DMR -> HDMI + EH495 NR ON, D925 HQ ON And yeah, I threw in additional samples where I also enabled the NR feature on the EH495, and where I also added the HQ circuit setting on the D925. Why? Because this thread is easily found through web searches and I also received PMs regarding this thread over the years. I like to think there is someone out there who might be interested in that comparison. |
Me take it easy? I couldn't be more easier than that, I sometimes edit my posts more than once to make sure the message is clearly delivered and yet (generally speaking) some will gloss over it like a todler flipping thru a political magazine pages.
I will examine the samples and get back. |
COMP.mov seems to have less rainbowing in the subtitles but otherwise more red/green chroma noise than S-VID.mov.

I thought so too, I don't know what type of comb filters both the LD and the DMR use, line or 2D but it looks like the OP could benifit from one of the modern 3D comb filters found in modern devices like the Eval board, SingMai or similar devices.

That sample picture is for demonstaration purposes only, I think it mainly shows the effictivness of 3D comb filter at getting rid of dot crawl, In the top image with the girl the levels are actually more right in the 3D one than the 2D one if you look at the background behind her, the bottom pictures are not that far apart in terms of levels.

Nah, I think the exposure is pumped, regardless of the background. Manufacturer marketing depts really suck when it came to "simulated" (FAKE!) images. Or cherry picked, just as bad. I know why you posted it, and we've now pointed out the surreal nature, so that's all it needed. Context. :salute: |
@lordsmurf: In case you checked out the aforementioned samples, would you also agree that S-video with the NR function of the EH495 enabled produces the most feasible results for LD in light of the described workflow and the hardware at hand?

To make a more informed decision, we need another sample from the LaserDisc, a short clip with high spatial frequency like a pattern on on a person's shirt, both moving across the screen and not moving.
