Option for MP4 Videos with Reduced Range [SOLVED]

[xahu34]

The menu entry in PTE for creating an MP4-video reads as follows: HD Video for PC and Mac, and this is what we obtain. I made the observation, when playing such a video with the integrated Media Player of a new Samsung TV, that these videos show some deficiencies.

I generated a short video including the image to be seen in the attachment. This image shows 5 grey squares with the indicated grey values (0, 8, 16, 24, 32). The video runs nicely on my PC: You can easily distinguish the 5 squares. On the TV, the squares 0, 8, and 16 are all shown equally in deep black. This is not surprising, as videos normally have a reduced range!

Using x264 (the H.264 encoder that is also used by PTE) I also generated a version of my video according to Rec601 (with restricted range), and the said problem disappeared. This kind of video looks a bit flat on a PC, but for a TV media player it seems to be the better solution.

So I would like to propose an option for MP4 videos with reduced range for the use with TV media players.

Xaver,

You're right! I just tested on my Epson TW2000 and also see this loss in shadow details.

On the computer I also reproduced this problem. The problem in encoded H.264 file. We'll investigate this issue tomorrow and will try fix it quickly. Thank you!

This problem doesn't occur with MPEG2 video files created in VideoBuilder.

Xaver,

Please try updated version 6.5.7 Beta:

http://www.wnsoft.com/test/picturestoexe-setup_657.zip

It should resolve the issue with loss in shadow details.

Also it includes your suggestions for German translation.

Please let me know about result.

Thanks in advance!

Please let me know about result.

I made a short test: No clipping of shadows, and no clipping of highlights, as well. The test video created with the new version seems to be standard compliant, now.

Also it includes your suggestions for German translation.

That's fine!
