[SUGGESTION] Image sequence as source

[MarcoRavich]

Hi there, this is a really great piece of software !

I have a set of 10000+ HDR images (or, better, frames 'cause it's a time lapse) shotted with my camera that i want to encode into x265 HDR.

It would be very useful (and quite unique, at least between open projects: afaik only AnotherGUI - which is free but closed source - have this feature) to input a set of images (frames) to encode.

Here's some - maybe - interesting links to implement it:

• https://gist.github.com/bpholt/465b64b20faf6bea3579abea5c047915
• https://medium.com/@sekhar.rahul/creating-a-time-lapse-video-on-the-command-line-with-ffmpeg-1a7566caf877
• https://en.wikibooks.org/wiki/FFMPEG_An_Intermediate_Guide/image_sequence
• https://hamelot.io/visualization/using-ffmpeg-to-convert-a-set-of-images-into-a-video/

Hope that inspires !

Definitely not a use case I imagined, but is something that would be very cool to add.

A few different ways to implement this would be:

• Separate panel that would be a list of files (importable by folder) that can be reordered. Then auto-create / use concat.txt file (most work, probably most user friendly)
• Support glob / pattern matching for source input, as well as setting frame rate
• Take a concat.txt file as input, and automatically add the concat type when detected. Then need some way to set frame rate. Could also have a "generate concat.txt by folder" option in menu. (easiest, but less user friendly)

I'm 100% on this request!

I'm a CG animator, whenever I render an animation it's 99% of the time as an image sequence, and I use custom windows batch scripts to convert them as video files (see L0Lock/FFmpeg-bat-collection).

And there are a lot of animators (pretty much all of them), or globally any kind of graphics artists, in need of a fast and friendly too to convert image sequences to videos. I happen to be nerdy enough to dive into CLI tools, but you can guess most graphics people can't do that.
Adding this feature to Fastflix would make a lot of people's like easier. And my repo useless, but that's not a big loss.

Hey @forart and @L0Lock finally added the ability to concatenate with FastFlix! Can either use your own concatenation text file, or build one from the new Tools > Concatenation Builder

Going to close this as the feature is added, but please feel free to add feedback / suggestion here or in new ticket if you have any!
