Video is distorted when trying to edit?

PostTue Mar 20, 2018 6:38 am

Hey guys,

I been editing with Resolve 14.3 for a few weeks now and have run into an issue when trying to edit some 21:9 video clips. I am getting issues with the video all stretched out to the point of it being un-viewable. I find it strange because some of these clips I was able to edit with out issues, but recently all the clips seem to have this issue.

Audio for these clips are fine in resolve and when I play those clips back with anything other then resolve it plays back without issues.

Does anyone have any idea what can be causing this?

Can you tell us about your hardware, the format of those clips and the codec?

The hardware that I am using is:
-Intel i7-7700k
-Nvidia GTX 1060 6GB (391.01 Driver)
-16GB 2400MHz ram
-Windows 10 Home (1709 build)

As for the video format/codec. Its using a MP4 format with the H.264 codec at a resolution of 2580x1080 @ 60. (Note - Videos that are at 1080p with the same settings don't show this issue)

You may be getting tight on your hardware.
Could you try to transcode some footage to ProRes or DNxHR and see if the error persists?

Just a update:

I tried converting to DNxHD, and it did work but the video was no longer the original aspect ratio due to the limitation of the software I was using. (ie - Did not support keeping 21:9 aspect ratio)

I have uploaded one of the clips that has this issue but the forum keeps complaining that I am not allowed to upload links to that clips. Any ideas?

Can you obfuscate the link, so it doesn't look like a link?

This clip is OK on Resolve Studio 14.3 on a Windows 10 system with a GTX 1050Ti card.

Are you using the free version? If so, I'll test that next.

Yes, your clip is not properly processed in the free version of Resolve.

We'll add it to the list.

If you want a quick fix, a Resolve license might be a consideration.
