Fading in and out with image?

I dont know if dissolve or fadein/fadeout is what I should use and what is best. I wan't the fade to begin at 405 with 29 frames fading in (only the image not the avi-file) and fading out with 29 frames and end at frame 558. This is the script I have so far: Code:

Maybe you want to restate your requirement a little more clearly. Fade, transitions from black to normal image, or the other way around. [in or out] Dissolve overlaps [in your case 29 frames], so that your result length clip is 29 frame shorter due to the overlap. It starts out using all of one image/clip, and at end of dissolve uses all of the other image/clip, so result contains a bit of both, hence the overlap requirement.

As StainlessS mentioned, the requirement is not quite clear, and we can only guess from the script that you have. However I gave it a try, excuse my newbieness though. Code:

It takes less than one second to do this in any NLE. This is the wrong tool for the job.

Oh sorry. I see it's quite vage. What i ment was that the image has an transparent (png) and i want it to fade in from "invisible". I did however solved it. I did a "trim" similar to patul. :) Thank you. ��

For my purposes, AviSynth accomplishes this sort of work perfectly well. In a matter of seconds, I can type exactly what I want to achieve without leaving the script that contains the rest of my processing/editing. This avoids involving another program, generating intermediate files, making additional renders, etc. For me, it's easier than using an NLE, but different strokes...

I give up. Why even bother trying to help strangers? This has become pointless.

For me, I mainly can't be bothered to try an NLE, its just something new to learn and easier to use what I know, old dog, old tricks. Dont give up John, its just this damn Covid silly season getting you down. :)
