I have a project 1920x1080/25p

My images are 1920x1080 at present the size is 1.48MB

Do I need to make the MB size smaller? What is the best MB size to use?

Is there a pacticular reason for asking this? It is for still images I asume. The file size (also) depends on the storage format used, GIF, JPEG, TIFF, BMP, etc. etc. More or less compression may have been applied. The color depth has impact on the size too. Etc.

I guess that in general one might say: the larger the file, the more information about the image it contains, the better result you would get when converting it into a movie. And conversion time for still into movie is less of an issue.
So, why do you ask?

The image is a jpg.

Reason I am asking, if this was a still image going into a web page I would compress it down to speed up the page.

Does the same apply for a video, or as you mention could this be a problem for quality.

In general, one does not have to care about the size of media used in web-pages anymore, because the bandwidth is often adequate enough. And yes JPEG images appear faster when smaller, but then the images would be of lesser quality.
For video the user knows and expects and accepts that there are more bytes involved, so you determine the quality. If you want more you go for more pixels and... for larger source files.
Look at what Youtube is doing, it offers various qualities sometimes even in a range from 144p to 2160p (4k). The user selects quality desired, (maybe) on the bandwith available.
The creator of such videos always submits the highest and Youtube converts downwards to the range. I am sure that the creator would use images of the largest size he has available.
Hope that this helps.

o, and btw: if you go for 1920x1080 and use smaller jpeg files, the quality of the video would be less, but still with the size of a 1920x1080 video...

Keith, many of us took a look at this in previous PD versions, have not redone again in PD18 but probably the same. A few basic notes:

1) If your native pictures are of higher framesize than what you intend to produce to in PD, (say 6000x4000 but plan to PD produce to 1920x1080) you get better quality in finished video if you use a photo tool to reduce to produce framesize vs PD

2) If you plan on doing some operations of the pic in PD, like pan, zoom, then you are better off with the higher native framesize and let PD reduce framesize or things like pan or zoom will reduce the quality of the video

pic size very important in web page, even this forum. Several users had "large" avatars and loading those pages at the time was extremely slow, as if the forum pages are fast as it is, users advised to follow forum guidelines (130x130) which eased strain significantly

That is a great help thank you.

One final question to close this:

My images are 1920x1080 at present the size is 1.48MB

Would you compress the image to lower that 1.48 before adding it to the project?
