I order to use with AVISynth, the above clip was changed from MP4 to AVI by first extracting the raw h.264 using "My MP4Box" and then converting to AVI using AVC2AVI. Here is a longer clip of the raw 1440x1080 output from the machine (you can't change the compression ratio, you can only adjust exposure, sharpness, and frame adjustment). Yes - the Reflecta does scan frame-by-frame but unfortunately it can only save the result as a highly compressed MP4 file (this is the main complaint of most users). Hi John - thank you very much for your reply! If you can upload a 10-second clip of one of your original transfers, without re-encoding, that will make it a lot easier to see what is going on. He has made some amazing advances over the past few years, some of which I still need to steal, er, incorporate into my own work, especially StainlessS' GamMac filter, which I still can't get to work reliably, but which shows great promise. You mention you are using a script dated 2012, but I thought VideoFred had posted something more recently than that. So, do the compression as the final step, if you need it, and not when you do the original capture. You can always compress the files when you are finished, in order that your final result doesn't require a huge array of disks to hold the final result.

So, if artifacts are the problem, then look for a setting in your capture software that lets you use less compression. The more the compression, the worse artifacts you will get. This is important because any video format that uses compression can use only a little compression (big files) or a LOT of compression (small files). You didn't provide any information about what settings you used. I see you are storing the original scans using H.264. That is a requirement for using VideoFred's script. I am not familiar with the Reflecta units, but a quick trip to their site makes it look like they must be frame accurate, meaning you get precisely one from of film on each frame of video.
It was tough for me to tell much from the Vimeo post. Thank you - all or any advice most welcome
I suspect the original scan is too heavily compressed?ĭoes anyone have any tips or suggestions? Should I use different parameters in the script - or a different method altogether? I'm completely new to this but can see the output doesnt look right. Output= latest 2012 VideoFred Script (default parameters) Input= Super 8 Reflecta scan at -1.0 exposure (scans as 1440x1080 30fps H.264 MP4) I have a little test clip showing a side-by-side result. I've bought a Reflecta Film Scanner super8/Normal8 (similar to the Somikon and Wolverine) and currently just experimenting, trying to learn the best way to scan and the best way to post-process.Įven though I realise the fantastic Videofred / John Meyer scripts on here are for the output of far superior scanning methods, I thought I'd give them a try. I'm very new to AVISynth, having just started trying to digitize my families old 8mm/Super8 films dating back to the 1950s.
