Testing the video quality of the Letv S1 X500 at the Port of Tacoma.
Affiliate Link above.
The Letv X500 uses h.265 format which is the newest compression format that maintains quality of the video (nearly twice the AVC format) at the same bit rate.
The file extension shows as 3GP which is a container format that is mobile friendly version of the MP4 format.
The video format is not the easiest to work with – Premiere Pro 6.0 does not recognize the format. I use format factory to convert the file to edit the video.
