![]() In that case, I could have used video capture (via something like OBS Studio) to record everything that happened on my monitor during that long browsing session. I wanted to find a solution that would produce a single output file, containing the results of all this website browsing and scrolling. While that was feasible, it would have required more time than I cared to invest in this primarily exploratory project. In theory, I could have divided the post-VisiPics set of 9,286 non-identical images into several hundred sets, each of which contained the screenshots capturing the contents of a single webpage I could have separately bulk-cropped each of those sets and then I could have used panorama software to stitch together the screenshots within each distinct set, producing hundreds of PNGs or TIFFs. Within my experience, panorama software would not find a way to stitch together disparate webpages that did not belong in the same panorama. The resulting set – comprised of tens of thousands of screenshots, before I used VisiPics to eliminate near-duplicates – may have captured the contents of several hundred websites. I had kept IrfanView capturing screenshots as I browsed among multiple webpages. My screenshots came from more than one webpage. But I didn’t have premium panorama software.Īnyway, there was a problem that would rule out panorama software in the present case. With premium panorama-creator software – such as PTGui, judging from my brief research – I might have been able to stitch at least some of those somewhat redundant images into a single long image. It was too limited and persnickety it would never handle the quantity of overlapping images I had here. Unfortunately, Microsoft Image Composite Editor, my default (free) panorama creator, was not up to a job like this. If that material overlapped sufficiently, I could combine it all into a single long (PNG or TIFF) image using panorama stitching. (To find that, I used MediaInfo > right-click on one of my cropped PNG files > MediaInfo > menu > View > Tree.) This made them tall and narrow, corresponding to the scrolled portions of the webpages. In this case, on my 4K monitor (i.e., 2160p, with a resolution of 3840 x 2160), the cropped screenshots measured 1036 x 1928. ![]() In the present case, unfortunately, some of the material was too lengthy for FireShot.Īnother possibility would be to use IrfanView to capture screenshots as I manually or automatically scrolled down through the webpage, and then use IrfanView to bulk-crop the resulting screenshots, so that what remained (on all except perhaps the first and the last screenshot) was only the scrolled material. The solution there might be to copy the FireShot results to the clipboard, paste into IrfanView, use Ctrl-Y to crop as desired, set IrfanView to display window width, and scroll the resulting PNG. For that, if the material was not too lengthy, I could use something like FireShot. I wanted to capture some webpages of the latter type. Others simply scroll downwards for a potentially long distance. Some such sites limit the amount of material displayed on any one page: they require the user to click a button at the bottom, to move on to the next page. Examples include search engine results, Facebook walls, and forums discussing various topics. Many webpages contain long discussions or presentations of information. Compared to the other options I was aware of, it appeared that IrfanView’s MP4 slideshow option, producing a video that would display one deduplicated screenshot per frame, might yield a fast, competent, and relatively simple output video, and that PotPlayer could display that video in the desired manner. I was willing to consult a table of contents, navigate to the segment I was looking for, and view the desired segment at a rate that might be fast, slow, or one screenshot at a time. I didn’t plan to watch the whole thing, as I might watch a movie. ![]() ![]() I wanted to produce a single, relatively compressed file, with high image quality, to capture that action. I had thousands of screenshots, capturing hours’ worth of scrolling action on webpages. ![]()
