This is my first post but I have an old problem.
It has been really cumbersome for me to simply render a video with both original audio and an overlayed audio track with good quality and small size.
My goal
VIDEO MP4 H.264 . compatible width browsers and iDevices.
The source can be different for each project
AUDIO . good enough quality. Can be MP3 96 KBs or ACC. Doesn´t matter.
The source is mostly MP3 128 KBs
Now for my first project the video source frame size is 1280x544 pixels with 23,976 frames/sec.
It took me a while to figure out how to render at these exact attributes. It cannot be done with Share - Create Video File - Custom - MPEG-4 Files (*.mp4). Frame size is at fixed standards.
I also must have 23.976 fps for the rendered video, otherwise the picture will not run smoothly.
The problem here is I cannot select H.264 and 23.976 fps with this MPEG-4 type.
After a few days I came to notice only Microsoft AVI files will accept my attributes of H.264 and 23.976 fps.
The video was crisp but then another problem arose.....
The audio for the original video have a slight cracking/popping sound. The video has a source of ACC 48.000kHz 16 Bit.
The overlayed audio with MP3 128 KBs was all fine and clear.
I have tried different audio formats - PCM, DV Audio, MPEG Layer-3 all, also with different bitrates - 48.000, 44.100, 24.000kHz.
This has turned out to be a huge dilemma for me.
The only quick fix (not so quick really) is to render it to FLV with desired Frame size and Frames/sec. Both Video and Audio are great, but the audio is limited to 22000kHz, and then use another program like Handbrake and re-render it to MP4.
OR
Create Sound File only and then merge it with with the video using another program like Handbrake.
So how do you guys do it?
I am sure not the only one doing this kind of video/audio editing
