IMAX Sonic Anthem – High Quality Video and DTS-HD MA 5.1 audio 2

IMAX Sonic Anthem - High Quality Video and DTS-HD MA 5.1 audio

IMAX Sonic Anthem

I recently received a higher quality version of the IMAX Sonic Anthem – Celebrating 1000 Theatres. This version has a video bit rate of 40 Mbps compared to 3.4 Mbps of the earlier one on the site. In addition the new file has a DTS-HD Master Audio 5.1 track instead of a lossy AC3 5.1 like the original upload. You can get the new version at the IMAX Pre-Show Trailers Page. Thanks Noah!

Here is trailer 1 for Angry Birds 2 (2019), which will hit theatres in August. You will notice that the lossless audio is encoded in DTS-HD Master Audio. Going forward it is my intention to drop PCM and DTS and use DTS-HD Master Audio instead. This should solve some other issues like odd channel mapping with PCM tracks in VLC, as well as issues some experienced with the old DTS 1536 kbps tracks. AC3 will still be included as a backup on mkv files.

With regards to HEVC (H.265), I am not going to be uploading any more trailers in H.265 until I can work out some issues I have experienced. I did an HEVC encode of Frozen II which, ironically, would freeze my computer when played and could only be recovered by doing a hard boot. It is my intention to provide HEVC encodes in the future, but it still needs some work.
