Reference: http://forum.cyberlink.com/forum/posts/list/51366.page . I could not locate the possible gaming 21:9 capture footage mentioned by Tony in the post to check out.

The 21:9 aspect ratio , 16:9, and 4:3 are all related. See this article : https://en.wikipedia.org/wiki/21:9_aspect_ratio . 4/3 squared = 16/9. 4/3 cubed = 64/27 or close to 21:9.

For a uhd sensor there is 3840x2160p, anamorphic pixel aspect ratio of 4:3.

There aren’t any 21:9 camera sensors according to this 2016 article: http://www.redsharknews.com/technology/item/1370-8k-is-not-the-future-of-tv-we-think-21-9-ultra-widescreen-is-instead?page=2 . It looks like that an anamorphic adapter on a 16:9 camera is the way to go to create 21:9 videos that can be edited and produced with powerdirector using PepsiMan’s technique.

Thanks PepsiMan. I trust that your technique works. I have not worked with 21:9 before until this morning. Find that through experimentation that you can’t set a 21:9 flag on a 16:9 video even when square pixels are used. FCP for mac’s can do it from what info available on the internet. Produced the video to be an anamorphic 1080p60 video using a custom profile of 2560 x 1080p60. I tried capture/convert with vlc but that did not change the flag to 21:9. Will work on it some more. The final result can be displayed properly on a 21:9 monitor with vlc by changing the AR to 2.35. See the attached.

Tried the PepsiMan alternate cinema widescreen method. It works perfectly on my 16:9 monitor. Please see the attached. For those with 21:9 monitors I would appreciate feedback on whether the attached mp4 can display full screen as predicted.

The difference in display in the attached screenshot can be reconciled with 3 produces. I will work on it to reduce it to two as in PepsiMan’s method. Did a shortcut range produce in the first step to see what will happen next. Basically followed his procedure.

21:9 material like screen captures or videos can indeed be edited in PD. Titles, PiP objects, etc. can be used to liven up the videos and then produced to a anamorphic cinema wide screen.

The discrepancy mentioned about the methods used above has been reconciled and fixed. The 21:9 game capture is placed on the timeline. Bar Glint III and titles from the 16:9 group that are not available in 4:3 can be used until you switch the AR to 4:3. You can then use the effects from the 4:3 groups to continue the editing if you want. Range Produce in 4:3 using a custom profile. Go back to the edit mode. Place the newly produced clip on the right of the timeline. I’m sure that you can do more editing at this point if you want but did not try it. Set the AR to 16:9, then in the clip attribute/4:3 to stretch to 16:9. Did another Range produce using another custom profile to lower the bitrate for testing. All done on one timeline.

Attached is the final video that should display as 21:9. Let us know if it can be full screen on your 21:9 computer monitor.
