Video 2mp4

Download File ===>

AVI is a video container that contains and encodes both audio and video. This container has less compression ability than other similar formats but still it is supported by most of the DVD players. The multimedia players must have the AVI codec in order to decode AVI data.

MP4, also known as MPEG4 is mainly a video format that is used to store video and audio data. Also it can store images and subtitles. Normally it is used to share videos over internet. MP4 can embed any data over private streams. Streaming information is included in MP4 using a distinct hint.

What I want to do is speed up the first video to 110% speed (without changing audio pitch) and then concatenate it with the second video (which will remain at normal speed), and I want the resulting video to have a bitrate of 2.5 Mbps (since that's what Wistia told me should be the minimum for my upload).

Currently, my first attempt results in a video where the 2nd part is all mangled and shows bright green, etc. My second attempt (of Step 4) results in a video that has a total bitrate of only 1645kbps.

What's happening is that besides the timescale difference between CC's output and ffmpeg's (which will only result in timing errors), x264 is producing a High profile stream with a different parameter set than CC's encoder. Re-encode the 2nd video with ffmpeg and your files should be matching. Alternatively, you can speed up in CC and export the 1st video. 59ce067264
