Neither of those options give you lossless compression (and in fact
the first one should be downsizing your images, which is even worse).
I had to create a video from a bunch of differently sized png images
once on Windows, and here's the command I used:
ffmpeg -r 30 -i %d.png -vf
My largest image was 3360x1080, which is why you see 3360 and 1080 so
much. You can replace those numbers with the width and height of your
own largest image (or bigger, if you want). This scale and pad command
will add black letterboxing and pillaring as necessary to the video
without resizing any image (and it will center each image).
You have to carefully choose your video codec though. Some video
codecs don't support odd widths or heights (as you can see), and some
give better quality than others. If you want lossless H.264 encoding
with libx264 (I believe it's defaulting to libx264 when you chose .mp4
without specifying the codec), you can pass -crf 0 to get lossless
Other video codecs, like libopenjpeg, will do lossless by default.
