    Enjoy your beer

    Yes, when working with machine vision cameras one might get lost in all those options.

    With my Flea, the format is 'format7 M0' and this means 16 bits raw color. If I understand it well, the picture is internal(in camera) captured at 16 bits, then converted to 8 bits for the output. And it's raw, so debayering is done by the capture software in real time. So, your modus F7 M2 might be similar.

    After some learnig, it looks like you will have great results!

    Another good day of transfer and a bit more playing with Film9.

    I have a question regarding the interpolation settings. I am wondering what would be the best settings to use to get rid of jittery movement on things like a swing set, or when the camera pans. I am currently getting jumpy looking results, ie like frames are missing. So instead of say having 100 frames in a pan shot I am only seeing 40 or 50. I tried interpolation, and smooth, and mixing, but I can't seem to get the right combination.

    Thank you

    PS Fred I reread both the camera manual and AVT software manual again today to find out why I was getting pixelation. Couldn't really determine the cause, perhaps something to do with debayering?? It almost looks like the debayer grid subtlety in the background, yet in the mode I am using now, even though I am still using the internal debayering, not seeing the grid. Oh well, Happy with the way it is working.

    And I think I have managed to get a few samples loaded onto the interweb. Hope these work okay. I think I lost some detail in the making of clips as I used Movie maker to split the 15 minute film. I wasn't about to learn Resolve tonight. Oh, and yes that's me, the little 2 year old in the films.

    Get the popcorn it's showtime

    Hello Kilohertz,

    The problem of interpolation is not simple on fast and panoramic movements.
    On your videos, I do not see the artifacts often usually caused when we interpolate.
    But, on the other hand, one perceives saccades, as if it lacked intermediate images.
    Can you tell us what is the frame rate of your source video ?
    And what are the parameters chosen in Projects and in the Interpolation window ?

    The quality and finesse of your videos is very good.
    However, if you have not already done so, you should clean the film to limit the vertical lines.
    The function of FILM9 is not always sufficient when the lines are too wide and numerous.
    And then, you can clean the borders of the image with the function "Black Edges".

    The excellent result happens.
    Gilles

    Thank you for your encouraging word Gilles, appreciate it.

    Source is 18 fps, and in project settings I chose 18 fps, with synchro, silent, and save as AVI H.264 10 Mbps.

    In the window "interpolation" I chose "interpolation, smooth and 29.97 fps"

    Stabilization is +3 and +3

    As far as the scratches are concerned, I have cleaned the film multiple times, I am using a deer skin soft shammy piece saturated in naptha with a small weight compressing the 2 pieces together, it is not a "wet gate" but more of a "damp gate". I could investigate making it more wet to help fill in the scratches. This particular film is possibley the worst for scratches, the other ones seem better.

    Borders, no I haven't tried that function yet and I will once I get the basics sorted out.

    So I think the software is excellent for this sort of work, and I am very happy with the results so far, it really exceeds my expectations of what can be extracted from 8mm film.

    Thank you

    PS link to my telecine machine if you are interested.

    Nice machine, it's nice to see people make their own scanner.
    I may be wrong, but it seems to me that this practice is much more widespread in Europe than in the American continent.
    While the quality you get has nothing to envy to professional machines.
    It may give some ideas to others, so much the better.

    For the cleaning of the film, 99.9% isopropyl alcohol is used.
    Otherwise I cry every day can not bring the "FilmGard" in Switzerland, it is a fairly expensive product but also reduces the stripes of films and allows to do the wetgate capture.

    For your interpolation problem, you can also try to work without interpolation on Film9 and change the speed on DaVinci Resolve.
    It's up to you to see what's best for you.

    Congratulations for your work!

    Your "damp gate" is not wet enough. There must be more naptha on the film. Use more shammy pieces to hold the naphta.
    It should be possible to hide almost all the scrathes.
    This is how I did it:

    Unfortunately, the C2D capturing software and the special RGB led lightsource is not available anymore for home users.
    It is now part of the Filmfabriek (Muller) scanner.

    Very well done! What light source do you use?

    Cleaning Naphta is cheap and it works great! It works even better when mixed with liquid paraffin.
    In my youtube tutorial I mentioned 40% but 10% will be enough. But it does no harm.
    I must change this in the clip

    Thank you very much Fred for these tips.
    Because of the translation (and my very low level of English), I had badly translated the word Naphtha ..
    I thought it was a stuff ....

    You are welcome!

    The naphta I am talking about is called in Dutch: 'wasbenzine'
    In French: 'essence nettoyer'
    The best translation in English I can find is 'cleaning naptha'

    I'm using it for years now and it's absolutely harmless for film.

    Fred.

    Thanks Fred. I have practically memorized your 2 tutorial videos, watched them many times. I will add more pieces and use more naphtha.

    I also searched high and low for the older free version of C2D but couldn't find it anywhere, it really looks like it would have been the perfect solution for me and eliminated a lot of struggle with AVT software.

    Thank you, I appreciate the compliments from someone with so much more experience than me. The LED is a 10W COB (chip on board) daylight balanced LED module. It is 10 volt DC at 1A and produces an amazing amount of light. I set the white balance in the capture software with no film in the machine so that is started off 255, 255, 255 and then locked it there. Any incorrect WB from the original film will have to be corrected in post.

    This is the LED, it's about 2x2 cm.

    Thank you for your compliments, It's good to know that I have somewhat succeeded with my project, it has been almost 3 months now of daily work.

    I will make a few tests without interpolation to see what results I get. I have Resolve loaded on my computer, but haven't yet learned to use it. That may be something I should learn.

    Thanks again!

    Fred.
    And this is something else I need to investigate. I have been using Coleman camping fuel, which is naphtha, but I haven't been able to find liquid paraffin. In my research this morning, I found variations of naphtha are called Kerosene, and something else called "liquid paraffin", this was a Wikipedia description for naphtha. Kerosene is cheap and easy to find locally, not sure if that would work? I also found "lamp oil" paraffin based, I wonder if that would be okay? There is also medicinal paraffin oil but haven't been able to find that locally.

    I'll try to locate liquid paraffin and make my damp gate, a wet gate.

    Cheers

    This is the paraffin I am using. Not for medical use of cource

    Quick update.

    Re: the jumpy-jittery flow of the film, I have fixed that by using Interpolation, and setting for 59.94 fps instead of 29.97 fps, made it perfectly smooth, although now it looks more like video rather than film, but super clear and smooth movements.

    I found pure paraffin oil, it's a very good quality lamp oil and it states 99.9% paraffin, so I will make some more tests today with the wet gate.

    Cheers

    Another update. The wet gate works great! I used about 40% paraffin and naphtha and then loaded up the little box holding the foam block and shammy pieces and kept it shiny wet through the capture....absolutely amazing results. Thank you Fred! cheers

    And one more PS

    Gilles et Roland, my only complaint now is about the Film9 window staying on top of everything else. Could you make it so it could be minimized please and thank you. I am trying to capture while processing and I can't see the bottom 1/4 of the screen.

    This is a request that has already been made to us.
    It is unfortunately not so simple that for an application working only for itself.
    But in the section "Tell me what you need, I'll tell you how to do without", first I scan all my movies and then I make Film9 work when I no longer use the computer with the function "shutdown "activated.
