  1. I’ve been happy with the sound from my HDS. I try to adjust the azimuth of the sound head to match the original recording head, just like when I digitise magnetic audio tape. the HDS does have a flywheel behind the capstan, it’s about 5 inches in diameter. I’d guess the audio quality could be improved by adding dancer arms. I’m no expert, but I would assume the dancer arms would take out inconsistencies with reel tension etc to reduce speed changes affecting sound. But who knows!
  2. Yes I'm not sure why the Australian Fixafilm presence isn't obvious on the website. Peter manages the Asia Pacific side in Canberra. He's a super helpful guy, I bought my FF HDS+ from him 🙂
  3. I recently borrowed a Film-O-Clean from a friend, I thought it was quite helpful to run a film through quickly to remove excess dirt with low risk of scratching. It wasn't perfect, it required a few runs to remove the majority, but in the end I finished it off with cleaning by hand with PecPads. I've ordered one, I think I'll use it in my workflow as the first run through on my table using rewinders. It would be helpful for the times a customer wants to view something to see if it's worth while doing a decent clean and scan of it, but you want to knock the dirt off that might cause scratching. The media pads are super expensive to purchase from wittner cinetec, but they are just 35mm media pads from Film-Tech cut in half. I've tried cutting them with a box cutter and then cutting the plastic core with conduit cutters. I'm not sure how they do it in a factory, I assume some kind of fabric cutting machine where it's a drop down sharp blade with no teeth, and the roll spins as it cuts.
  4. Resurrecting this thread because it ranks on the first page of google when searching for film scanning places in Australia, and I thought it would be helpful to actually have some directions on it for people that stumble across it! There are a heap of places in Australia that offer film scanning, but most are using old SD retroscans or similar low end scanner. If you're looking for a high quality scan, run by some great people - Check out these places Fixafilm - Canberra - Arriscan + other high end MemorylabFilm - Melbourne - LG Scanstation + FF HDS+ Bowline Media (Me) - Newcastle - FF HDS+ there are probably others out there, but I don't know them so I'll leave it for others to recommend them
  5. No I do use Iso Alcohol, I just confused myself if Todd wanted to try a fluid that might provide different results, or change the delivery method. I use Gamsol for wet mounting photographic negatives on my flat bed scanner. It works very well, but you need to clean it off with alcohol after as it's oily.
  6. Ok I think that's a good move. I wouldn't bother looking into Gamsol then, it's an oily liquid. It's probably the same as FilmGuard, just not a branded label for film. I just wasn't sure if you were wanting to see if you could get better results from the HDS foam rollers w/ Iso Alcohol by either changing the delivery method of the fluid, changing the fluid itself, or both! I think the delivery method of the foam rollers is very good. I couldn't say if the Film-O-Clean will improve, but worth a shot if you're up for it!
  7. For me, it wasn't worth the hassle... I got fed up with tinkering with my moviestuff and the perfect oporunity came up to purchase a HDS so i jumped on it and i'm over the moon with the HDS. I have considered selling the parts i've made, but i see how many hours roger has to spend telling someone how to do a very simple task on the scanner, that i get worried i'll be bogged down with support! Also that the machine will undergo a design change, and my mod won't fit anymore. A few things i did to my MKII: Built a wetgate similar to the pictor, right before the lightpin/gate built an intergrating sphere and lit it with 3 YUJI 98+ CRI leds (stock ones i *think* are around 70 -80) Changed lens to Schnieder Componon with m42 helicoid made a simple cable from RJ12 trigger cable to FLIR GPIO cable for Blackfly Camers (trigger to line 2) and played with FLIR blackfly 5mp and 12mp cameras. It's possible to make the moviestuff a working 4K scanner, but it needs a lot of work. A few issues i never got around to making a solution (to make it 4K) 3 axis camera adjustment/linear stage. The included one is very basic and has large teeth which make fine adjustments difficult. It's also largely plastic, so it's not solid. You touch an adjustment wheel and it's moved slightly, and the weight of a larger lens causes the plastic camera mount to flex. It does work fine with the stock camera. quality 3 axis linear stages are expensive. the original OWIS one the early HDS models uses cost around 3000 euro. the lightsource - it could be brighter, and higher CRI. When you add a 12mp/4K camera, it has a larger sensor and needs a longer extension tube, loosing even more light. Also, the DOF is shallower, needing the focus to be precise, and the film to remain flat in the same spot The gate/guides - they are no good for warped film, and they made it difficult to design my intergrating sphere around it. Ideally a whole new gate and light box would be made. the lightpin - it's too close to the exposed frame, so the larger lens hits it. Also, it uses reflectance which doesnt play nicely with wet reflective liquids on the film. it eventually stabilises, but you end up with big jumps at the start and around splices. Ideally it would be moved futher away, or swapped to a through hole style fibre head. The scanning speed - It's locked at 15fps for 8mm, (less for larger formats) unless you make your own motor control which wouldnt be terribly difficult for someone smarter than I. It's just that 15fps is pretty fast for 12mp capture over USB3, you might find it would drop frames. The software - there isnt a film specific capture software that is like the moviestuff software. You either have to use Spinview which is the evaluation software bundled in FLIR's SDK, or you can try StreamPix which was made for general machine vision capture, but it's over $1000 to license it. As it turns out, its what the Reflex scanners use i*think* I think for the price, it does a great job, and most uses LOVE it as you can tell on the facebook group. I'd say the HDS is also good value when you price up the components they've used. The machining quality is also very nice. it's so smooth to run, it's super quite, the software is simple and gives great performance, and the LEDs are incredibly bright. I think they can produce about 600w of light at full power as they are on for such a short time, and they are overdriven. The light on the moviestuff is about 30w constant. I can properly expose horribly dark 8mm film.
  8. Yes good point, you just reminded me, the capstan on the HDS does sometimes slip a little while i'm doing a wetgate, but you can just click then tension up a little, slow the scanning speed, or ease off on the alcohol. I've never handled filmguard, but from what i've read it sound oily. I can imagine the HDS capstan really struggling to grip. But yes Todd, if you're going to get one anyway, no harm in giving it a go and seeing how it works out 🙂 Otherwise if you think filmguard is they key, you could always try soaking the wetgate rollers in filmguard. Another product i use for wet scanning is called Gamsol, it's sold at the art shop nearby. It's an oily liquid that i use on my epson V850 flat bed scanner with the epson wet mount kit, it works great for scanning scratched or odd sized negatives. I chose Gamsol because the official KAMI liquid can't be shipped to Australia. Maybe you could try one of their liquids too.
  9. I'm not sure if i'd add it in line on my HDS, i'd probably reserve it for the rewinding bench. But it's a good idea for moviestuff owners. I'd probably whip the film through it a couple of times while i add leader/tail and tension the reel before mounting it on the scanner. At the moment i'm cleaning film by hand using these - https://www.bhphotovideo.com/c/product/71154-REG/Photographic_Solutions_PAD44_Pec_Pad_Photo_Wipes.html I either use iso alcohol if i want a fast drying solvent, but if the emulsion is sensitive or there's a magnetic strip, i'll use IsoparG as a 2nd option. It's much slower drying and the fumes are much stronger. but it's safer for some film and doesnt remove magnetic particles from the sound stripe. I hold the cloth in my hand soaked in the solvent as i slowly wind the film through, changing the pad very frequently to avoid using the trapped dirt to scratch the film. I haven't tried anything labled as film cleaner as I would take a wild guess they they are most likely using an off-the-shelf solvent combo.
  10. It's not a wetgate. It's a wet gate. It uses Isopropyl alcohol so it doesn't do the same thing as a proper wet gate with perc or trichlor, which have the same refractive index as the film base, to fill scratches. And at that, with a diffuse light source like the HDS is using, a proper wetgate would be of minimal value because the light isn't collimated. Does it clean the film right before it enters the gate? Probably yes. I mean, you can use 99.9% isopropyl to clean film and it works fine. Our Lipsner Smith Excel 1100 uses it. But is it performing the same function as a wet gate? It is not. Dude, it's a wet gate. It's wetting the film as it passes through. The delivery method doesn't have to define what it's called, or the solvent used. I've never used another scanner with a wetgate using a different solvent, so i can't compare. Anyway, I couldnt care less about what people call it, or what the old fashioned machines used to deliver it. This simple method the HDS uses with just two glossy paint rollers does a terrific job of filling in cracks and scratches before being photographed. Sometimes the most simple methods are the best! And you haven't used one, so i'm not sure how you can questions it's effectiveness Also regarding refractive index, i don't know what the refractive index of acetate or polyester film bases are. But i'm sure someone on here can pretent to know or make it up. Here's what google told me the two solvents are: Iso 1.3772 at 20°C Reference Perc 1.519 reference I'm not sure your point regarding film cleaning? this isnt their purpose. Sure, for arguments sake - the rollers would probably lift a bit of loose dirt, but it would remain trapped there on the roller and probably end up back on the film a few ft down. I don't have a film cleaning machine, nor have I ever used one, but i was under the impression the buffers (i suspect paint rollers) rotate while being sprayed with fresh solvent to allow the dirt to fling off.
  11. I would avoid modifying it that might damage it. These machines would be very useful to keep to digitise magnetic audio on film. It’s not too difficult to build a scanner from scratch like a moviestuff scanner
