Multi frame interpolation

[Tarun K]

HI,

How do we run the BMBC model for multi frame interpolation? run.py always seems to output one frame irrespective of the time_step parameter.

Hi,

For brevity, the run.py generates a single intermediate frame in time t.

It's a bit annoying, but the simplest way for multi-frame interpolation is to modify the configuration in the command and execute it multiple times.

This is the example for x4 video interpolation.

    $ python run.py --first images/im1.png --second images/im3.png --output images/im2_025.png --time_step 0.25 
    $ python run.py --first images/im1.png --second images/im3.png --output images/im2_050.png --time_step 0.5 
    $ python run.py --first images/im1.png --second images/im3.png --output images/im2_075.png --time_step 0.75

Thanks! Can you share pretrained models for multiframe interpolation?

[Junheum Park]

Sure.

We use the same pre-trained model at any time_step parameter.

Hence, provided pre-trained model in README can be used for multi-frame interpolation.

For your convenience, I am attaching the corresponding part of the README.
