1) Find a video-editing program that is cheap, of good quality and easy to use.

If you have found a service to do the scans for you and you get it back from them or you have got it back from us, upload it on your computer for editing. Then import these files on the editing program of your choice. There are many editing programs, but keep in mind that you don't have to use many features that are present in these editing programs. Especially fancy features are present in expensive editing programs. Luckily you don't need them and you can go along with a editing program for approximately  50 dollars/euros perfectly. Try to figure out the editing program to do all the basic things you need to do such as placing, cutting, mixing, fading, speeding up or slowing down your video files. Also mixing your audio and music and the capabilities of the editing program to deal with this. You'll need multiple audio channels. Preferably 3. At least one for dialogues, one for music and another one to be sure for audio effects or adding surrounding sounds.

2) Arrange your scenes and synchronizing with the dialogues

If everything went the way it should go, you’ll have all the video files of your scenes and sound files

on your computer in your film folder. Arrange these scenes and import the dialogues in the desired order in the editing program. Now the most time consuming part of the editing will be to synchronizing the dialogues with your images. You will shoot 18 fps. That means that your images will go faster than your audio. You'll have to stretch your images to synchronize with the audio. It may be that you'll have to do this by cutting up a video sequence and slowing down them from time to time part by part to match the dialogues. It will have this effect of footage to play normally, then slowing down a bit and then retain its normal speed again. Don't worry if this looks amateurish to you. It's all part of the Super 8 characteristics, where you will have to deal with, jitter, blurriness, tilts and other inconsistencies in your images. So it won't be a big deal. The most important part is to have the dialogues to be in sync.

3) Add music, sound and titles with your images

Import the music and sound  and put it under the particular images. Add the movie title, subtitles, intertitles, intro and closing credits. Render it to the desired video format.

Applying after affects and other gimmicks is of course possible, but not necessary, since we are not dealing with video images. The stock material is super 8 mm film with its own unique images. This already looks like film because it is film... you save a lot of time by using your video-editor just to arrange your shots, mix your music and sound and render it out to the demanded format.
