Dear Spear,
Thank you for the information.
To avoid the quality problem with images converted to video it is highly recommended not to use MPEG2 and MPEG4 codecs to create the video to.
Besides, while converting to H.264 codec try to increase the bitrate of the output file to get better quality: the higher the bitrate - the higher the quality of the video created.
Thank you for understanding.
Kind regards
