I have a video on my HTC desire which is 15 minutes long. I need to find a way of emailing it to my Mum, preferably in a format that will be easy for her to open. I tried 'sharing' it but it said the file was too large to attach. I connected the HTC desire to my laptop and transferred it, but the file was still too large to attach to gmail. I then decided I could edit it into sections and send them separately, but the 3gp format wasn't recognised by windows movie maker so I tried converting it to avi or mp4 but it then said the file was corrupted. Help?!
