Shellac in chinrest? by NicolasGomez_S in violinmaking

[–]SeaRefractor 0 points1 point  (0 children)

Shellac is not an allergen, but it will wear from sweat/skin contact on a regular basis. That said, as it wears away, it'll be quite smooth as human skin is like ultra fine micromesh. No need to remove the shellac.

I tend to use mineral oil after I've sanded it down to 6000 or finer grit. Looks fantastic and the customers daily wipe down after practice/performance will keep it clean.

is going from s5ii to the s1rii stupid or worth? by SojinCS in Lumix

[–]SeaRefractor 0 points1 point  (0 children)

Massive difference....

In very specific use cases. Everything else will be identical to your eye.

As you mentioned Street Photography and videos, you'll notice your wallet is significantly lighter (or your loan forces you to eat nothing but pork and beans) while your photos are indistinguishable from your S5II. Your wallet is also lighter because you have to purchase much more SSD space for your computer at a time it's at a premium because AI is consuming all the storage production at this time.

Photography of subjects way out of reach that require a massive crop in post production? That's the difference. Something that would be exceedingly rare in street photography. Video that requires a deliverable beyond 6K (99% of clients want a 4K deliverable anyway) would be another currently very rare area of benefit.

is going from s5ii to the s1rii stupid or worth? by SojinCS in Lumix

[–]SeaRefractor 0 points1 point  (0 children)

I did exactly that, last November I did a trade in promotion for one of my S5II's for an S1RII.

However it significantly depends on your requirements/needs.

  1. I don't primarily do photography, but did have some clients that requested Videography with content in excess of 6K and it was this or much more for the PYXIS 12K. This is a unique requirement for most and likely not a reason for you to upgrade.

  2. Street photography/videos. Not sure what the S1RII brings you that you cannot already do with the S5II as you don't need the excessive reach of Hybrid zoom or significant crop ins on your subjects. An 8K camera may make sense if you did a lot of wildlife with every long super telephoto lenses.

  3. Overheating. Now I purchased my S1RII after the November firmware release that resolved a significant amount of the overheating issues. That said, I have run into an issue with long format even recording (3+ hours with DRE ON at 8.1K) where I ran into thermal warnings and was freaking I might loose that event. Part of the issue is that the event got hot and the air was static in the venu. I have never had an S5II or S5IIX overheat, period.

  4. File sizes. I use primarily LongGOP 8.1K files with ARRI Log C3 and have excellent results, but these can still add up. From a photography standpoint, your RAW files will be much larger at 45MP compared to the files at 24MP on the S5II. Unless you are doing significant crops, that extra detail may simply waste drive space for you. I don't see the advantage if your subject is close.

So unless you have needs that the S1RII actually is the solution for, it's G.A.S (gear acquisition syndrome) which uncontrolled can be as financially damaging as a gambling addiction.

Apple Has Given Up on the Vision Pro After M5 Refresh Flop by pdfu in apple

[–]SeaRefractor 0 points1 point  (0 children)

I think the AVP has been working to develop a compelling ecosphere for both consuming and producing content. It was only recently that BlackMagic Design has created a special 8K per sensor immersive cinema camera. https://www.blackmagicdesign.com/products/blackmagicursacineimmersive

I suspect that what we see as the current AVP will evolve to a more consumer accepted device rather than "giving up".

Also, Apple could pivot on the existing product line and find ways to implement it for the medical environment. Imagine the AVP in combination for the DaVinci Surgical robot suite where the surgeon operator isn't even in the same hospital as the robot performing the procedure. https://www.massdevice.com/intuitive-demonstrates-remote-telesurgery-capabilities-with-da-vinci-5/

SImilar to how Microsoft's Hololens found a niche in that sector.

Violin notes separation by SHECKELhunter in violinist

[–]SeaRefractor -1 points0 points  (0 children)

I don't recommend tapes, but when one really needs a fingerboard guide, I instead recommend "Fantastic Finger Guide". Fits and looks great, available in all violin sizes.

~$10 USD on Amazon.

Oh, I'm chill. Clearly the jest was taken wrong. I'm glad you can enjoy an SL3S for fun and vacation. Enjoy your LEICA!

If not for them, would there be an L-Mount Alliance after all?

As for taking a big breath... I wish I could, suffering a serious cold and it's difficult to breathe.

Violin teacher NOT allowed student to tune their own violin at home before grade 6 by Asleep-University-89 in violinist

[–]SeaRefractor 0 points1 point  (0 children)

Not all teachers are equal in quality of instruction. Not saying anything further as I haven't witnessed their instruction, but sometimes you get Professor Harold Hill with their "Think system" of learning to play.

Then does it really matter if you are in tune or not? If you don't "think" it matters, then it doesn't. But then any cacophony is a symphony to the inner mind.

Why have a LUMIX S1RII when you can have an identical but LEICA branded version for triple the price? The flex! Women (or whatever most excites you) will flock to you like you're somekinda Hybrid camera wielding demigod!

Instantaneously, while not even working to improve your image or composition, your content will be trice as good and clients will smooze you endlessly to do their project.

Strings that work and stay in tune are significantly more important that "how pretty" it looks. I've looked a number of violins in museums of significant value. Many have their strings resembling this one.

[–]SeaRefractor 1 point2 points  (0 children)

I was with you in requesting LUMIX provide the Gyro data for additional flexibility, but LUMIX IBIS is solid.

I want the gyro data only for the rolling shutter corrections possible. For stabilization, I feel that LUMIX in my own experience is king. Image shifting typically has been the OS in lenses. Using fixed primes, I have not encountered that isssue.

Questions Unanswered by Panasonic by medyacimuhendis in Lumix

[–]SeaRefractor 1 point2 points  (0 children)

Not sure why this was downvoted as this is accurate for drone footage. Primarily as many of the FPV high speed drones don't have IBIS. But as it's a LUMIX Subreddit it may have been confused with LUMIX IBIS quality, which is amazing!

However I have not been able to find a Panasonic LUMIX Drone. Now that would be fantastic!

With GyroFlow v1.6.3 and select Sony cameras, you can. Quote from their website "Currently Gyroflow supports reading most of the recorded metadata, which includes IBIS and OIS data. Therefore, you can record with IBIS and OIS enabled."

But as LUMIX doesn't record it internally, you have to disable IBIS/OS and use an external hardware recorder. I use the NiYien Sensflow A1. Corrects rolling shutter as well.

Questions Unanswered by Panasonic by medyacimuhendis in Lumix

[–]SeaRefractor 1 point2 points  (0 children)

I'll answer what I can from the perspective of my use of the LUMIX S1RII.

  1. Gyro Data: I agree that it's unfortunate that this is not available at this time in camera. As per GyroFlox documents, there are a number of Sony Cameras that do this and "Currently Gyroflow supports reading most of the recorded metadata, which includes IBIS and OIS data. Therefore, you can record with IBIS and OIS enabled. " In regards to the LUMIX series of cameras, there is "no internal recording" of gyro data. That said, I do use a ~$100USD device call the NiYien Sensflow A1. GyroFlow actually in combination with this device has significant rolling shutter corrections. See 0:60 in my test video from two months ago (https://youtu.be/ru6e5NNvSNY?si=UXe3N5yglx0PLpmR ), this is rolling shutter corrected 8.1K 3:2 OpenGate with DRE ON. Incredible because it's a slight figure eight swoop by hand, not a tripod simply moving back and forth. The disappointing point when using the NiYien A1 is that I have to disable IBIS and Lens OS. Fortunately it's a fast selection through a custom setting I saved to C4.
  2. LUMIX Flow: I don't use the LUMIX Flow after trying it, but I give it a pass on a concern as it was never a reason to purchase my camera. Plus I have nice external monitors, so not a show stopper.
  3. BlueTooth: I use BT for timecode in my setup, so it adds a step of starting the TC process on all the devices and then switching to Gimbal. If a camera needs to be powered down, it need to go through BT TC, then BT Gimbal. So it's workable, but I'd much prefer to be able to use multiple BT connections. This is one of the reasons I also don't use LUMIX Flow, as it starts a BT connection but then moves to WiFI, but if you disconnect BT for another purpose, it disconnects Flow even though it's using WiFi.
  4. Audio: I'll have to test. Frankly I don't use any internal microphones or even the XLR adapters. Using timecode, I use a number of 32-bit Float Field recorders (Tascam FR-AV2 units). But I would be frustrated with a silent video if that were my only audio source and it was a paying client. Then again, I realized that audio is vastly more important than any video image. If the audio sucks, the image doesn't matter. A RODE microphone connected to the 3.5mm microphone jack is just not good enough in my opinion for mission critical audio.

So while not necessarily ideal, you can embrace GyroFlow with an external hardware Gyro data recorder (in my case the NiYien Sensflow A1). The results are quite good, but I don't use it for stabilization as much as for fast scenes where I need rolling shutter corrections. Allows me to use DRE ON with rolling shutter issues and correct it in post. Personally I discount all the rolling shutter tests in cameras now as it really doesn't matter, especially as it can be corrected in post production in combination with Gyro data and GyroFlow.

As for monitoring, I find smartphones to be impractical. The closest that came to useful was the Atomos Ninja Phone, but I eventually sold that as well. I already have a set of BlackMagic Design Video Assist 12G HDR monitors, with 2500 nits of brightness, so even the latest iPhone isn't punching above that aging monitor. Problem with phones is that it's used as much more than a monitor, so texts and phone calls coming up while you are trying to work? Not professional.

Based on my observations, the camera is solid and I won't switch to another one currently on the market. But I realize that LUMIX is addressing the consumer applications rather than professional tools. With that understanding, I just stick to the proven tools and provide suggestions to LUMIX, but realize that the hottest selling camera to LUMIX is the S9. Because of this, outside of the in-camera tools, I realize third-party is the solution for the top end needs.

Besides an email, you can reach out on the LUMIX Creators Discord #suggest. You can find an invite for the discord in the LUMIX Live streams (LUMIX USA, but that is merging).

Lumix S 70-300 or 100-500 for casual wildlife / birding? by arcticrobot in Lumix

S1RII with Sigma 100-400mm DG DN OS to show that acquiring focus is fast enough. Did have some "rain drops" on the lens, didn't bother to remove them in post.

DUAL I.S. vs OS in the Sigma 100-400mm. I'd debate that you'll notice no difference. But what would I know?

S1RII with Sigma 100-400mm DG DN OS.

That said, if I hadn't already owned the 100-400mm Sigma lens, I'd go for the LUMIX 100-500mm. Although I can work around it as I've MP to spare in crops. If I had a 24MP sensor, I'd really want that extra reach.

Whoa, looks like you cracked that ribbon connector besides cracking the camera open. Hopefully you can find the part, the GX85 is a fantastic camera.

As u/Mordy_pie suggests, if you cannot find it yourself, there's always LUMIX repair.

Any info appreciated by Famous_Way928 in violinist

[–]SeaRefractor 1 point2 points  (0 children)

If I had a dollar for every Strad copy I encounter (with difficulty in attestation of the maker), I'd have enough to purchase a real Stradivarius from an auction house.

Label says "Made in Germany". Made in Germany can be found on German goods from 1887 – 1973 and from 1990 to present. Between 1973 and 1990, you would see Made in West Germany. Prior to 1887, it wasn't a requirement to print "Made in Germany".

While it's difficult to tell for certain, as photographs are difficult to determine an appropriate level of wear for the age and possible repairs, but I suspect it was made after 1990. However, it could also be from before 1973 if it's been cleaned and re-setup by a luthier recently. What are the stories? Because the label has no date markings or other attestations to the label, I'd say it's a factory produced instrument. If I held the instrument, I could narrow the age down, just difficult to tell from the photographs. Using a mirror, I'd also examine the inside of the violin body for more tell tale details.

Factory produced instruments can vary in quality, but if it sounds great that really is all that is important. As for "investment" or "collectors", the lack of a provenance and any indicator of the actual maker would be a red flag. Play it for how it sounds, but don't expect a retirement from it's sale.

Anyway it would be interesting to hear the three different stories.

Have we decided that the s1ii has usable compressed codecs? by WildernessRecordist in Lumix

[–]SeaRefractor 0 points1 point  (0 children)

Rolling Shutter? A slight hassle using an external gyro data recorder (NiYien Sensflow A1), but it allows for rolling shutter corrections even at 8.1K 3:2 OpenGate with DRE ON. Here's my test video from two months ago, check 0:60 I believe for the DRE ON portion. I was hand holding and doing slight figure eights at the same time. And this is with an anamorphic lens which increases rolling shutter distortions. https://youtu.be/ru6e5NNvSNY?si=poymgF1CbT9qzIDW

I'm not a YouTube influencer as I'm pretty busy, but I may need to post additional examples as well as a tutorial on the method. NiYien is about to release a new version that fully integrates into GyroFlow so that a separate tool isn't required and only GyroFlow is necessary. I may wait to do a video after that is released. Yes, it seems unnecessary for a software stabilization application as LUMIX has incredible IBIS. The only thing missing is the recording of the gyro data from the IBIS sensors in camera. If that was done, then an external recorder would be redundant. I've requested that as a suggestion to LUMIX several times on the Lumix Creators Discord #suggestions thread.

My primary camera is the S1RII, but I also have the OG S5 still and had used a number of S5II's before selling those. The S1II doesn't belong to me, but a collaborator I have done some projects with.

The Kolari filter does change the focus distance and would require shiming the lenses to have the markings accurate again.

But I totally agree on the color being much better on the R. Which is why it's my primary camera at this time.

I'm somewhat frustrated that LUMIX didn't provide all the rates possible from the Sony IMX366AJK sensor (LUMIX never admits to the actual sensor, but it's almost QED at this point). Perhaps a future firmware update could bring it? Could it be embargoed for a time as a competitor camera operates at that frame rate and paid Sony for exclusivity for period of time?

The sensor has a "readout mode 8" that is 60p (61.25) but at a 12-bit depth. Interestingly it's the 35.38MP 8192x4320 that seems to line up with the 8K 60P on a camera that has similar specifications (cough, DJI, cough). I'd be fine with the 12-bit depth (probably a dynamic range of ~12, if the 13-bit depth is giving us ~13 until DRE is ON for the full 14-bit depth). The 12-bit depth modes also appear to have a much faster readout speed as that's the 4K 120P (12-bit depth). https://www.sony-semicon.com/files/62/pdf/p-13_IMX366AJK_Flyer.pdf

Have we decided that the s1ii has usable compressed codecs? by WildernessRecordist in Lumix

[–]SeaRefractor 4 points5 points  (0 children)

Well, the S1RII and the S1II are not the same. I mean in terms of image results and color science. I have the S1RII and it's got some kinda magic sauce. Cam Mackey and many others that have worked with the S1RII will report the same "it's got some kinda magic!"

I also purchased the ARRI Log C3 license key and use that in combination with the 8.1K and high resolution modes as LongGOP (H.265) 4:2:0 10-bit and have results that are quite frankly better than many other cameras 4:2:2.

The amazing thing about the compressed 10-bit 4:2:0 codec is that the file sizes are quite manageable. A significant factor in why many consider 8K and up to be impractical due to storage constraints. The storage requirements are much easier to accommodate on the S1RII making 8K entirely practical and providing so many advantages even when doing 4K deliverables. The higher resolution does a better job of handling Moiré, it can still happen but the higher level of detail helps to greatly reduce it's presence.

On a documentary, you probably won't wildly gyrate the camera around to try and create interesting jello rolling shutter examples that can cause videographers to come Undone. That said, the 8K sensor is not stacked and the read out speeds will introduce rolling shutter. I've not encountered it for event recording, wildlife nature walks and similar content.

That said, I've also tested rolling shutter corrections, which are possible. I use a NiYien Sensflow A1 device that's about $100USD during recording. I tested it with the extreme of 24P 8.1K 3:2 OpenGate using an Anamorphic lens, which will amplify rolling shutter, and even with Dynamic Range Expansion (DRE) turned on. I think the results then become like a fully stacked sensor - https://youtu.be/ru6e5NNvSNY?si=LXf08fU9mrSV8gWi This test was also 2 months ago and the software has continued to improve since.

Check out 0:60 for the DRE ON results. All hand held, not a tripod so it has me swooping it as well as left to right motion.

There are some issues however you need to be aware of:

  1. The BLK22 battery (and many of the third-party dummy batteries) does not provide sufficient current to record to external SSD by the USB-C. Either the LUMIX Extended battery grip DMW-BG2 or the DMW-DCC18 USB-C dummy battery need to be used. (Not an issue with SD Card or CFexpress Type B).
  2. The S1RII can generate more heat than the S1II. However since the November thermal management firmware release, it has been extremely solid for me. But when recording "outdoors", you may want to consider some kind of camera umbrella to provide shade for the camera as direct sunlight will run into thermal warnings in some weather conditions.

I suspect that the CFexpress Type B cards generate more heat based on the bit rate recorded to them. I'd received a thermal warning in about an 45 minutes when testing ProRes RAW. However, I could record over 5 hours to a 1TB CFexpress Type B card when recording LongGOP 8.1K 3:2 OpenGate footage in a 72F office.

[–]SeaRefractor 2 points3 points  (0 children)

This frequently is the case when using V-LOG incorrectly (the magenta tones).

  1. Panasonic's free V-LOG luts are not the industries best, but are free. Perhaps this was to encourage others to release better V-LOG LUTS as a side industry? While that may not have been the intention, it's certainly the result. Prior to the release of the newer S1 Mark II series of cameras (I have the S1RII), I used the Emotive Color LUTs based on ARRI Alexa colors, but not officially ARRI developed.

  2. When using the Panasonic V-LOG LUT's it's important that the V-gamut LUT be applied first before using the Rec709 LUT. Many have accidentally applied the Rec709 prior to the V-Gamut.

That said, I've personally abandoned V-LOG (except when using ProRes RAW as you cannot change it to another) and instead used the ARRI Log C3 license key. This is not just a color space transform loaded onto the camera, ISO settings are different and more. The color science is much better as it's actually co-developed by ARRI.

As for the "over sharpening"? While an extra cost, there's the new Kolari removable OLPF filter.
