Hello Borate
Thank you for your response. Apologies for my lack of clarity.
I am on version 7.24.
I created my original draft videos on Auto Match Content (2500 by 2304). They were the correct size. Then it stopped working, stopped exporting images. only a blank screen and audio were exporting.
Tonight after reading your post, I tried a resolution of 1080 by 1920 vertical resolution (9:16). It worked. That is, I got the images back. The only problem is that they are a much smaller in size and do not look good on the advert I am working on.
so, my problem is how to get it to work on 2500 by 2304 like it was doing before.
I hope this makes it clearer
Thanks
S
