A memorial video for each part of the funeral service

Start with a part set to music. Add your own MP3 and place the photos; they spread themselves across the length of the song. Each photo is on screen for 6 to 8 seconds, so a four-minute song (240 seconds) carries 30 to 40 photos. If you have fewer, the sequence comes round again by itself, so the picture never runs out before the music does.

Clips from a phone (MP4 or MOV) can join in two ways. The first is between the photos. The song keeps playing and the clip's own sound stays off unless you switch it on. A clip counts as fixed time: put a 30-second clip into a four-minute song and the photos share the remaining 210 seconds, which is room for 27 to 35 of them. If a clip runs long, trim it to the moment you want.

The second way is a video compilation: a part made of one or more clips played back to back. For every clip you decide whether its sound is on or off. On for a wedding speech, perhaps, and off for holiday footage. You can lay background music underneath and set its volume so a voice stays clear. When you download, each part is rendered as one MP4 with picture and sound together.

The best clips are often on somebody else's phone. Invite family and friends by email as helpers. They get in with their email address and a code, and add their photos, videos and music to the shared collection.

HEIC photos from an iPhone, JPEG and PNG all work straight away, as do scans of old prints. Nothing needs converting. Everything runs in the browser on a phone, tablet or laptop, with nothing to install.

It all lands in one collection. You decide which pictures go into which part, and so into which film.

Pick the song first and the photos second. A three-minute track wants roughly 23 to 30 photos; a five-minute track, 38 to 50.

In the extended view you can look up and listen to music through Spotify and YouTube while you build the film, to hear whether a song suits the pictures before you add the MP3.

There is no editing software to learn. No timeline, no cutting clips, no nudging a soundtrack until it lines up. Put the photos and clips in order, choose the song, and the timing works itself out.

You see what you are getting first. The preview plays everything with music, as often as you like, with a light watermark over it. The film itself is rendered when you download; transitions between pictures may differ slightly from the preview.

Making, viewing and changing it is free. You pay once, at download, with no subscription. After that you can download again, in another format too. If you would like help with the structure, the assistant in the simple view can set up the parts for you; everything can also be done without it.
