How to shorten an MP4 video file size

[pierret18811376]

Hello,

In Premiere Pro project, I have used 5 mp4 video files.

At the origin, the total amount of these videos is of 150 Mo (for the 5 videos).

When I export my Premiere Pro project in H264/MP4 with the same settings, the video file size created by Premiere Pro is of 900 Mo.

1 - Why ?

2 - How to shorten a lot the 900 Mo video file size created with Premiere Pro ?

Lower the bitrate when you render out the video. (High bitrate=large file, low bitrate=smaller file.)

Hello,

I have made a screenshot of my settings. Is it corresponding to the bitrate you are talking about?

As you can see I am at 10 Mbits/sec. Do you advise me to change this setting ?

[Averdahl]

Yes, that setting will have a direct effect on the file size.

Ok. 

I am at 10 Mbit/sec. What is the limit (in Mbit/sec) to preserve a good quality ?

[Averdahl]

It depends on the footage. The more details and motion in the video, the higher bitrate must be used. Less details and static shots require less bitrate.

There is no "best value" to use, so you have to experiment and see what fit your needs best.
