Thumbnail image of HD videos
I have found that the thumbnail/preview images of uploaded video files are not available for HD video files. For such videos, the browser shows
videoIcon400.jpg icon image of the pawtucket. However, for low-resolution videos, the browser shows real representative image of the video content as thumbnails. See the screenshot.
Is there any way to create thumbnails for HD videos?
May I expect some help in this regard? I tried with several video resolutions and sizes, such as, 1920x1080, 1280x720, 720x576, etc. But none of these generated thumbnails of the videos, though video plays correctly in all these configurations.
I suspect, the tweaking needs to be done in the
media_processing.conf. Is there any guideline somewhere regarding the generation of thumbnails for uploaded video files?
Did you checked in Manage - Administration - Configuration check, that "Video" plugins have the status "Available"?
CA uses ffmpeg to generate previews. You should make sure the ffmpeg you have installed supports the "HD" video files you are uploading.
Hi darrigan and seth, thank you for your responses. ffmpeg is installed in my system. I have uploaded here the screenshot of my configuration. I will be grateful if you can have a look at it and suggest me further.
I don't see anything wrong here... Could you send
Darrigan, sorry to ask this naive question: how can I upload that file? I tried, but here it says "Uploaded file type is not allowed"!
Good question 😄 may be it considers text file as malicious... Put your file somewhere, like with https://wetransfer.com/ and give us the link.
Or copy/past text in Word, make a pdf...
Also, send a short video file (or a link) for which preview doen't work for you, I can try in my Providence to see if preview works fine or not.

In another post (https://collectiveaccess.org/support/index.php?p=/discussion/comment/3073), Seth said:
CA will extract preview frames. The number and frequency are set in the app.conf file. If ffmpeg cannot extract frames for some reason, usually related to the frame size and/or aspect ratio of the video vs. the preview frame, you'll get the icon. Since ffmpeg is something of a moving target, it is sometimes possible to get preview frames to work when they previously hadn't by varying the parameters CA uses.
I tried to change the format of the short video you sent to me, to see if it works, but not yet success.
