@SekharBu1 Your this question is same as your previous question https://experienceleaguecommunities.adobe.com/t5/adobe-developer-questions/investigating-the-use-of-....
Browser support for .mov is poor. Refer to SOF here.
You can always upload and return mov as raw binary. In your default_filters.any in dispatcher, make sure to allow your extensions like this
/0107 { /type "allow" /extension '(doc|docx|xlsx|xls|csv|mht|mp3|ppt|pptx|txt|renditions|psd|pdf|tiff|tif|heic|mov)' /path '/content/dam/(web)/.*' }
And then on .html try
<video width="1280" height="720">
<source src="lightbulbs-h264.mov" type="video/quicktime">
No video support.
</video>
only safari on mac works as per here.
