Editing mp4 makes file size much bigger
I was emailed a little :15 video clip to which I wanted to add a :06 jingle. No biggy on the edit, just cropped some of the audio and squeezed the jingle in at the end. When I went to output it, the file size jumped from 2MB to 18MB. It was an mp4 file, resolution was something weird like 700×404 or something (don’t quote me on that, but it was something like that).
As far as the output settings, I used H.264 as the preset (choosing mp4 from the dropdown list forced the resolution to a smaller size for some reason, so I didn’t use it) and chose the “Match source” for the other options. The only way I could get the output file size down to a reasonable 5MB was to choose a medium bitrate. It didn’t appear to affect the video quality, so I went with it. However, this isn’t the answer. Was the original mp4 that was sent possibly compressed using an expensive hardware compressor/encoder, maybe? I don’t understand why adding a simple :06 jingle could make the file size jump so high.
Facepalm.

You exported it with a higher bitrate than the original file.

I do have Compressor to use, so that option exists. Gracias.

I was searching for details of the original file to figure that out, but couldn’t find that info anywhere. Doesn’t Premiere allow me to view the original encoding bitrate?

You know the size and duration so you could use simple arithmetics to figure that out.

Oh sure, make me earn this why don’t you? 🙂

It’s a basic skill that you’ll probably use a bunch so yeah. Earn it.
