Optimize the Remotion output with ffmpeg command : crf, maxrate and bufsize using Lambda #3232
Description
Feature Request 🛍️
Having the possibility to override Ffmpeg Command in Remotion Lambda to optimize the output.mp4.
The idea would be to be able to configure this kind of settings : -crf 22 -maxrate 5000k -bufsize 10000k
That would permit to use CRF to avoid waste a lot of unnecessary bandwidth in some case when using VBR or CBR, but to cap the max bitrate to also avoid 10Mbps on a 720p video that is supposed to be delivered to the Web for example.
Use Case
The feature should permit to optimize the output of remotion based on our needs.
A video that will be used in a local environnement do not need to be encoded the same way than a video that will delivered to millions of people using a CDN.
Possible Solution
The first solution would be to add the options maxrate and bufsize to the renderMediaOnLambda() function.
Another solution would be to create a function similar to overrideFfmpefCommand() but compatible with Lambda
