Question regarding video encoding formats samples #7

Closed mgogoulos closed 6 years ago

Hi, this is very nice and useful project! I tried config.py's video formats and was curious what scenarios they are optimized for. On a 60MB mp4 file,the mp4 high version produced was more than 200MB and I found that strange

Cheers

Hey, when I created the package, I just googled for some parameters, which seem reasonable to me. But I don't have that much experience regarding video compression. In this particular case, I suspect that the source resolution is lower than the target resolution. In this case, django-video-encoding will just upscale the video, which of course results in a bigger video file. This is already known, but I had not the time to fix that https://github.com/escaped/django-video-encoding/blob/55959549a154e89cfbb0adb33bd0e01205071f59/video_encoding/tasks.py#L61

I opened two tickets regarding these issues (#8 and #9).

Does that explain your issue or do you think the source of your problem is somewhere else?
