'I have recorded a video of my wedding anniversary bash, and one of my friends created an audio mix meant explicitly for the celebration. It was full of energy and fun. Most of my friends did not manage to attend, and now they want to see how it went. We get in touch with Messenger Facebook, but I have been getting this message of 'message failed to send' & 'not delivered' whenever I try to send the video. So please, someone to direct me on how to send a video on messenger.'

Sending big videos might fail to upload if your internet speed is slow and often takes longer to upload.

To make it easier to send large video or audio files via Facebook Messenger, you can first cut off the useless part to reduce the size of video/audio and then compress them.

Before we show you how to send large video/audio on messenger, let us update you with what you need to know and satisfy before proceeding.

Part 1. Video/Audio Upload Specs Limit of Facebook Messenger

One of the reasons why the video or audio you are sending on Facebook Messenger fails is that messenger does not meet the messenger's upload specs. The maximum attachment size is 25 MB. So you may need to change the video resolution for sending the file on messenger. The correct dimension for a video should be an aspect ratio range of 9:16 to 16:9 with a maximum frame rate of 30 frames per second. Video with more than this frame rate will be decimated in whole integers until it falls within the said range. It is resampled for audio according to the initial video sample rate to 22,050 Hz or 44,100 Hz.
