thanks very much
I have made new sequences using these settings - for sequences that hold combination of jpeg and video images
and have successfully nested 4 sequences in a master clip!
Thanks for your help - much appreciated.

That's great to hear... one thing to keep in mind... it's not bad to create lower-level or foundational sequences which avoid cropping and scaling source material which is larger than your output resolution (i.e., 1080p). In fact, sometimes you want to absolutely avoid doing so. For example, consider the following cases...
- You plan to use the same image in several places, each one focused on only a portion of the larger original source image, cropped to 1080p. In this case, down-scaling the image in a foundational (source) sequence as part of importing and setting things up can lead to lost quality later when you up-scale for your various uses.
- You plan to pan the larger image within a 1080p space... meaning the 1080p window within which the viewer watches your video will pan across the larger image which is not entirely visible at once... it is panned. In this case, you want your pan to be the best possible quality... down-scaling on import or in a foundational (nested) sequence will just lead to up-scaling senselessly later, hurting quality.
It can't hurt to have a foundational sequence with oddball resolution settings matching an image you imported... just remember to scale/crop it when using it in a sequence matching your export format such as 1080p. For standard photo montages where someone imports and needs to use each image only once, and therefore can crop/scale each image once... often getting the images to the export format right away is best... just beware it's not always best to do that. It can sometimes hurt quality. If one has multiple uses of images planned, including tighter cropping with scaling later, cropping/scaling "too soon" it can damage quality.
This is all to say your original sequence hosting the JPEG which had non-1080p / 16:9 resolution settings was fine... you could have scaled it down when using it in the higher-level sequence. If you only have one use for the image, with one cropping... then scaling it down/cropping it to 1080p right away is fine, otherwise, consider cropping/scaling as desired per usage in the project, keeping the source or foundational sequence unscaled or as relatively unscaled as makes sense.
