The iPhone version of AI Mastering has been updated to v1.2.5.
・ We speed up video upload and reduced transfer volume .
It is now possible to master videos encoded with H.264 and H.265 without re-encoding the video part .
In the past, all videos, including video, were uploaded to the server, and the server generated output videos. Therefore, when the capacity of the video part was large, upload and download took time . Also, in order to reduce the transfer volume, the smartphone sometimes re-encoded before uploading. Re-encoding took time and the image quality deteriorated .
In the modified version, in the case of an MP4 movie made with H.264, H.265 + AAC, the video and sound are Demuxed (separated without degradation) on the smartphone side, and only the sound is uploaded and mastered. When mastering is over, download the sound after mastering, Mux the sound and video on the smartphone side and combine them with no degradation to create an output video.
For all other videos, upload the entire video as usual and make the output video on the server side. In this case, the video is re-encoded to H.264 + AAC MP4.
As a result, speeding up, high image quality, and transfer volume reduction were realized.
※ In the case of MP4 movie made with H.264, H.265 + AAC, the video part can not be seen when the one uploaded in the smartphone version is viewed in the PC version or in other smartphones. Please note.
