I just started using AllVideos plugin (ver 4) for playing videos on my client's website.  However, they want a preview to appear instead of the blank screen.  Been researching this and found someone who asked the same question a few years back, but never got an answer.  Also found someone else who said that MP4s are played using QuickTime and that a preview wasn't configurable.

Does this still hold true?  Or is there a way to display either the first frame of the MP4 or an associated image file?  If it's possible, what's the syntax we should use?

I have tried {mp4}MP4FILENAME&image=IMAGE.JPG{/mp4}, but it doesn't work.

Thank you for any help that might be out there in the wild today!

Did you read AllVideos documentation?

Yes, I have read the documentation.  That doesn't necessarily mean I understand it completely though.  Would this be the way I can display a JPG that lives in the same directory as the MP4 on the website's server - not on YouTube or some other remote server?

Easy, descriptive syntax for media embedding. Use: {format/provider}filename{/format/provider}
You can also use syntax like: {format/provider}filename|width|height|autoplay{/format/provider}
For example, an "autoplaying" YouTube video of 600x450 dimensions would be displayed adding this to a content item: {youtube}he73js822|600|450|1{/youtube}

The autoplay parameter works great, but there are 5 video tutorials on one page and configuring them to autoplay won't work.  I took screenshots of the first frame of each video in hopes to display the static image until someone clicks on the video to play it.

Is that possible?

Have you already got a solution for this?

Trying the same with flvremote...

Just put a jpg in the same folder as your video file with the same name as your video. Make your image the same dimensions as your video file.
test.mp4
test.jpg

Joomlaworks needs better documentation.
