I use the online converter called cloudconvert at https://cloudconvert.com/ for most of my conversions. Below are 3 images showing a task I'm trying to figure out. It is the 2nd image where I think I'm having problems.
From reading the cloudconvert documentation it seems the only way to resize a video is to use ffmpeg. I tried to do so (see 2nd image below) but when I go though the conversion process I get an error (see 3rd image below). I'm trying to resize a 1080p video to 720p
I think what I need is a ffmpeg expert. Please look at the images below. I added notes to each image to give you an idea of what I was trying to do.
If anyone has any suggestions, please post.
Thanks

The error message it's giving you is related to the path of the output file
d: is not legal , it should be
Code:"d:\end.mov"
Your scale parameters are not correct either, it's width:height
"720p" usually refers to height .e.g. 1280x720 means 1280 wide by 720 high
The way you currently have it it will scale to 720px wide and adjust the width to the AR (so if you started with 1920x1080 your final video will be 720x405 - which will throw an error unless it's RGB or YUV444, not the usual YUV 4:2:0) . You don't have error handling in the scale code; odd numbers are not allowed with 4:2:0 subsampled chroma)Last edited by poisondeathray; 10th Aug 2015 at 20:42.

Thanks for getting back to me. So if I want it to be 1280 wide by 720 high should I enter it like this:
-i end.mov -vf scale=1280:-1 d:\end.mov
or like this
-i end.mov -vf scale=1280:720 d:\end.mov
Again, thanks for your help -
You cannot be sure that the file is actually called "end.mov" on the server. If you read the description, you would know that your command should look like this:
Code:-i {INPUTFILE} -vf scale=-1:720 -f mov {OUTPUTFILE}
