Question

Unscaled Nesting Lowers Resolution Quality

I found some previous topics on this, but most of the threads were several years old, so I wanted to ask about the current software.

My main sequence is 720p. I have a ton of footage in 1080p. To enable warp stabilize, I nested the footage in a 1080p sequence. The scale of the original footage inside the 1080p nested sequence is at 100%. On the main timeline, the nested sequence is at 100% as well, so there is absolutely zero scaling.

Despite this, I see a noticeable decrease in picture quality when playing from the main timeline. If I click through the nested sequence and watch the original footage, it looks fine. When I export, the quality loss persists.

What's going on?

      Just wanted to say I've got the same problem! The only workaround would be exporting the nested sequence and then putting that exported video into the timeline. Please help, Adobe.

        Help with what? That is how nested sequences work.

        nested sequences take on the resolution of the sequence regardless of the content.

        No it isnt. Its degrading the HD footage  to sub 480p levels. It is not shown like that in the sequence. Just on export. Its a bug.

        Noticed this recently, using 4k footage from FX9, placed nested 4k seq into 1080p timeline, export at Proress HQ and the guality looks like it's 2MB bitrate. In seq timeline it looks great. 

         

        This is still a problem, or a feature, can't tell anymore with Adobe.

        right click on your nested sequence in the main 720p timeline and 'Set To Frame Size'

        Try it and let me know

        "Set" just seems to scale the nested sequence down to 67%. Scale to Frame size shrinks the footage as well, but leaves the sequence at 100% scale in Motion > Scale. Is that expected behavior?

        Yes this is normal behavior, what was happening with you is that the footage in the nested sequence

        is larger than the final 720p sequence, that which affects quality, it should be scaled down to match

        the final sequence from which you are exporting... + you are kind of cropping your frame if the

        sizes do not match.
