Very slow video rendering

[adnanhassan23]

To create a video of 50 seconds with 3 images(each of 3 seconds) is taking around 10 minutes(600 seconds) to create on production server. Am i do doing anything wrong?

same here.

In order to make a 12 second clip, it took editly 21 minutes and dropped a bunch of frames. Here is my config:

{
  outPath: 'output.mp4',
  clips: [
    {
      layers: [
        { type: 'video', path: 'input.MP4', cutFrom: 14, cutTo: 26 },
      ],
    },
  ],
}

For ffmpeg to do it directly, it took 3 seconds and appeared to not have dropped any frames.

ffmpeg -ss 14 -to 26 -i "/Volumes/SeagateBlac/biking video/raw/20230623_evening_0.MP4"  -c copy output.mp4

I'd be happy to help devote time to debug this issue further if you have any time for that @mifi.

I think this project is a great idea and I'd love to be able to use it, but it seems I need some help with that.

I don't have time to work on this now unfortunately. I would recommend https://github.com/mifi/reactive-video as a much faster alternative to editly (but more limited)

@mjperrone @LittleTerry @adnanhassan23 are you all doing your rending on a cloud server? I've noticed that editly is currently really slow on a headless machine without a GPU.

I just joined the project and am hoping to do some profiling at some point to see if I can speed it up. Stay tuned.

No, was doing rendering on my macbook pro.

I've used editly in the past. It was always slow for me on a gaming PC with an i7-4790 and a GTX 980. Took about an hour to render a 10 minute video. Worth it for the featureset, but took patience. I remember reading something about it being CPU bound, meaning it doesn't use the GPU even if you have one.

I've read that somewhere too, but I think it's possible to make ffmpeg make use of the GPU too, but I never managed to make it work

Thanks for the info. I’m working on some refactoring now, but will look into performance soon.
