I have a lot of audio I wish to convert to video so as to upload to google photos and youtube (to get the transcripts). There is only a single image (white text on black background) for the duration of the audio (between 10 and 45 mins of audio).
I would like to good quality audio (AAC and 384 kbps) but i want just want a low quality image to speed up the export process. The image is for easily distinquishing the recordings in google photos.
can someone recommend some settings to make this a fast process to export. maybe something like:
720 *480. (can i go lower here?)
GOP 15 fixed
constant bitrate of maybe 2500k
this did make a difference (adjusted from youtube settings) but i was hoping for even greater video compression while keeping the audio quality the same.
does anyone perhaps have some better suggestions?
