About keyframe save.

[haoyan14]

Hey hello, I really appreciate your work and still have a few questions to ask. I want to retrain D-NeRV on the ucf101 data set I made, but the extraction method is not the same as the extraction method in your paper where your video will be extacted for 2fps per second. and I would like to ask whether there will be a big difference in the final result between the way of save the keyframes directly in the png format in torch and your way of compressing the keyframes with other methods and saving them?

And also, it would be of great help if the code for dataset processing could be made public. Thanks a lot.

Hi. If you want to achieve the state-of-the-art video compression performance, applying image compression on the keyframes are important and necessary. Without compressing the keyframes, the video compression results will be much worse due to the much larger keyframe size. For the dataset processing pipeline, you can refer to #2 (comment) for more details.
