The power of Avisynth: restoring old 8mm films.

[maks-lee]

Hello!

I have a modified 8mm projector, which captures one frame at a time. As i think, after capture i will need to create an avi file to feed to Fred's script first.
Is it possible to modify script somehow to import sequence right away after capture ?
I have tried ImageSource with no luck.

"With no luck?"

You'll have to be more specific than that. Please post your script (just the ImageSource line is enough), how the pictures are numbered, and the error message VirtualDub gives you when trying to open that script.

I have not used ImageSource

ImageSource Wiki

but I have used similar features in VirtualDub and also my NLE, Sony Vegas Pro. The only issues I have had with either of those is that

• You have to have a numbering sequence that conforms to what the image import function expects;
• You have to use an image type that the function can read (i.e., JPG, TIFF, PNG). Some only read a few types
• And, with some, you cannot have any gaps in the numbering sequence.

To avoid gaps, you can re-number the sequence prior to import.

Hi maks-lee. I posted my script earlier in this forum which shows ImageSource in use. See: https://forum.doom9.org/showthread.p...04#post1877304

The important lines are:

film="E:\Videos\imgseq\SAM_%05d.jpg"

Set the name and number to match how many digits your images use.

trim_begin=1 trim_end= 28160
play_speed=18

Set how many frames used.

source1= ImageSource(file=film, start=trim_begin, end=trim_end, fps=play_speed).FlipVertical().converttoYV12()

This is the ImageSource line which calls the previous variables. FlipVertical flips the image as theyre upside down when captured and then converted to YV12 so the plugins like AutoLevels can be used.

Hope that helps.

@manono, @johnmeyer, thanks!

Thanks! It seems, that now i can feed sequence to VD after capture, many thanks! I will continue to read forum (still so much interesting)

Thanks G2K4.
I note that x86 version is 5KB, x64 38KB, checked and x64 is static linked (no runtimes required).
I also note that old x86 version (that I have) requires runtimes MSVCR71.dll which is I think from VS 2003 (maybe also VS Toolkit 2003).
Just observations.

Dont know what x64 plugs might require AvsRecursion x64, but I've added to my x64 system32 dll storage folder, and also system32.
I'll shout if something goes BANG !

I made a new VC10 build with 32 and 64 bit binaries. These require VS2010 runtimes as it should be. I have added it to my Avisynth Stuff.

Please discard the build I posted before.

Roger Wilco, over and out.

EDIT: AvsRecursion by Rainer Wittmann (think that might be Kassandro)
For:- AvsTimer, RemoveGrain, ReduceFlicker, RemoveDirt.

IIRC, AvsRecursion is not needed in RgTools

The filters with T letter are not included in rgtools.

Hi all, I recently purchased a moviestuff Retro-8 Pro scanner and have been transferring films and would like to try out fred's script. I have a pretty good knowledge of avisynth, but am just looking for a little direction on what is the best route to take.
I have been exporting 1080p PNG image sequences of the captured film from the moviestuff software. Would it be wise to clean up the edit in Premiere and then re-export a PNG image sequence which I would then process with Fred's script?

Any advice on where to start with a script? I know there is Fred's original script, and then John has posted some modifications as well as some others.... I've been reading through a lot of this thread but it's pretty overwhelming.

Thanks

It depends on the footage specifics and what you mean by "clean up the edit in Premiere"

What were you planning to do in PP exactly ? What are you doing in PP that cannot be done in the avs script? or what are you doing in PP that would benefit the results of the script processing ?

I guess removing junk(leader, etc) off the start and end, cleaning up any blank spots in the middle...although I guess technically that could be done in avisynth too.

Yes, that's a good idea

Correct.

I'm trying Minusthebear script on page 64. When I try to run it I get this

AVSMeter 2.9.9.2 (x64), 2012-2020, (c) Groucho2004
AviSynth+ 0.1 (r2772, MT, x86_64) (0.1.0.0)

I don't know what 'super' means.
(C:\Users\ME\Desktop\Seemtobe working\newtest.avs, line 205)
PS C:\Users\ME\Desktop\Seemtobe working>

Referencing this part of the script.

#DEGRAINING/SHARPENING
#...................................................................................................................................................................


super_mv = MSuper(cleaned, pel=2, sharp=1)
backward_vec2 = MAnalyse(super, isb = true, delta = 2, overlap=4)
backward_vec1 = MAnalyse(super, isb = true, delta = 1, overlap=4)
forward_vec1 = MAnalyse(super, isb = false, delta = 1, overlap=4)
forward_vec2 = MAnalyse(super, isb = false, delta = 2, overlap=4)

Any Ideas why?

If I comment out those lines it runs. But it's running at 30FPS when I set it to 16 and I only have trim set to 300 but it says 1315 (this changes with different frame input but I can't see a pattern). Where is it getting 30FPS why 1315 frames? I am inputting PNG image files. Thanks for any help on this.

Do I even need FPS in the script if I'm just using image files? Seems I just need one in and one out as I'm not making a video yet. Inputting 2048X1600 PNG files from a 8mm film converted from DPX files.
