Unfortunately, 720p is too big for mobile phones and users with low bandwidth connection. I too would like to see the ability to produce 360p videos. |
Hi,
First of all thanks for creating this great library it works super quick compared to a lot of other methods.
With our project we are recording video at 1080p 16:9 so we can make use of some camera features such as stabilisation, however we need to output the video at 640x360 resolution we have managed to get this working with your source code however we are finding that the output video is quite bad and has lots of artefacts unless we set the bitrate very high.
Do you have any suggestions on how we can improve the output quality?
Thanks Aaron
