Exporting videos with filters outside of snapchat
Hello Lens Studio Community!
I have a question that might seem a bit strange. I am a research assistant at the University of Groningen, and me and my supervisors are looking to perform a study where we want to make people try to recognize facial expressions when they are wearing a face mask (Corona-pandemic). For multiple reasons, we want to edit 3D face masks over already existing videos of people that we have in a database, and we figured that Lens Studio may allow us to make such videos.
I have an idea on how this could work, and I was wondering if anyone could tell me if this is actually reasonable. First, we'd make a template/filter for a 3D face mask that 'follows' the face. Then, we'd upload our facial expression videos to Lens Studio. Finally, we'd add our mask template/filter to these videos and download the videos from Lens Studio, now with the participants in the videos having the 3D masks on.
Does Lens Studio allow for this? I'd love to hear from you!
Best,
Bart
If you published the lens then you could open it in Snap Camera, then you could use a virtual webcam running the video as the input cam for Snap Camera, then using a recording software record the snap cam feed.
That's probably the most effective way to do it like this.
However this would take a long time if you have like 50+ videos of course, in that case you should probably hit up a CS or data science class at your school to see if they could make something to automatically do it since face tracking libraries are widely available and not terribly hard to create with for devs.
Hi Brandon, thanks for the quick reply! I actually managed to get it going somewhat in Lens Studio, but I will definitely have a look at Snap Camera as well, as Lens Studio is a bit restricted in terms of video length (max 10 seconds) and the format (only vertical videos).
Luckily, we will probably only need to use less than 10 videos for this particular study, so the time investment is doable I think.
Thank you for the help, I greatly appreciate it!
