Default [Q] Option to scale video when sending via whatsapp

When I take a video that is 1 minute long, and try to send this video via whatsapp, it will limit me to sending only 20 seconds of the video.

On other phones, Galaxy S3, and Nexus S, Nexus 5, it actually defaults to scale down the resolution of the video, and send the video in full.

1. Is this a problem with the phone or with whatsapp, I have sent a support email to whatsapp and haven't gotten any reply.

2. Is there an easy to use app that can help me to scale the video down before sending via whatsapp? I tried searching on playstore but they all seems complicated.
