Hello Szabi,

My film project is finished, no need to work on it anymore.

many greetings,
Fred.

Hi Fred,

The reason for asking because I am near to Netherlands at this time.
I remembered what you told about good transfer needed several years ago.
I hoped we might make an arrangement on that.

Regards
Szabi

Question to you.
.
How do you improve 8mm old films, especially
big black spots,
small compact spots,
small dots and dust,
thin white lines,
thin black lines,
thick hair lines (avoid real hair),
thick black lines,
lines contacting motion, avoid motion areas,
long horizontal scratches,
long vertical scratches ?
.
Thanks.

,Thanks.

The answer to that question is to go to post #1 in this thread and then start reading. VideoFred provided his script and has described how it works to fix most (not all) of the defects you listed.

One of the defects which are not removed by his scripts are lines which persist from one frame to the next, like scratches created by running the film through a dirty projector gate. They cannot be removed with any of the software techniques discussed in this thread. The best way to remove them -- and VideoFred has discussed this -- is to transfer the film using a "wet gate" transfer where you put lubricant on the film prior to transfer. That lubricant physically fills the scratches and makes them almost invisible.

To add on to John, Fred provides his wet gate solution on one of his YouTube videos.

Hi

I run out of my timeframe slowly .
My alternate plan is to check transfer nearby.
I found mediafix and film-retter in vicinity.
Does anyone have experience with them?

[johnmeyer]

I asked ChatGPT and they confirm that Mediafix does use a frame-by-frame transfer. You absolutely MUST have that. So, they pass that test.

Film-retter also uses frame-by-frame scanning. There is a picture of their equipment on their site. It looks similar to the equipment VideoFred built for his own use, and similar to the units sold in this country by MovieStuff. They should provide reasonably good results. The "ultimate" is to have the transfers done by a company which has a Spirit scanner, or something similar.

Since I don't live in Germany, I cannot provide any help on whether either company has good people or whether they know how to use their equipment.

so for image, shows

ie result frame 201, which is clip R1 [EDIT: I've actually called it V1 in the script, R1 is a generic name originally meaning "Replacement clip 1"]
frame 1000, (with alternate clip NickName of "PontinsRainedOut_77").
EDIT: Of course the clips can be different sources, I've just used FlipHorizontal etc for demo.
All clips must of course be of similar dimension and colorspace.

Sorry Fred for cluttering this thread,
I suspected szabi would not create new thread to re-ask question for which he/she was chastised.

EDIT: What the Fade stuff does for audio {FadeIn=True,FadeSplice=True,FadeOut=True}, avoids clicks and cracks.

Hi

I am more or less ok when the video is on my harddrive but steps before that. I am without knowledge.
My first thought was the post by VideoFred 11 years ago, I never imagined I will be in vicinity but seems this option is not available.
Thanks for checking this I go for one of them.

I have to realise I forget a lot about the usage of avisynth.
I started using video editor software more I used avisynth less and now several years later it is complicate for me.
I still have that eight super 8 family video I would like to have a better transfer now until I am here.
I try to figure out what I edited 11 years ago.

Thanks for both of your help.

Film scanning: berola.de comes into mind as well (Forchheim, but you will ship your footage anyway.)

Thanks, I check it.

Hi, I'm converting some 8mm film to digital. I used a frame-by-frame technique, PNG frame capture, and a UVC camera.
I cleaned the film with a cloth and Avio solvent. But the frames have some stains and streaks. I wanted to try
the popular Videofred scripts, but I can't find them. I tried clicking the link in the first post, but nothing happens.
Can someone help me? Thanks (automatic translation)

[StainlessS]

I tried clicking the link in the first post, but nothing happens.

Downloads fine for me in Downloads folder.

Thanks for the file and the information. Unfortunately, the "Newest version of the script:" link doesn't work for me. It produces a flash that opens the page and stops, but the download doesn't start. Have a good evening!

[StainlessS]

link doesn't work for me.

My link does not work either ???

Try a different browser. (or maybe even your phone)

[videoFred]

Thank you Stainless for explaining everything.

The link works for me, I have tested it on different computers.
If you click on it, it seems that nothing happens.
But on the background, it is downloaded the 'downloads' folder.

I am using Firefox but you can also copy the link and paste it in your favorite browser. That should work too.

Fred.
