comment ffmpeg to cut intro and replace with new intro
Please post stream info for both files. You can get that by running 'ffprobe -i filename.ext'. It also appears near the top of the ffmpeg console output.

comment ffmpeg encoded videos are not playing on mobile browser
Doesn't seem to be that issue as non-encoded videos are playing fine, and if those videos were uniformly non-MP4, the OP would have noticed.

Your Stroke effect is not shown as enabled in the screenshot at Graphic Design. It is, right?

comment How can I reduce the size of a webm to 2MB?
You can also check by setting a low b:v and trying various crf values. When the CRF value leads to a solution lower than b:v, that's the resultant bitrate, otherwise it's close to the b:v

comment How can I reduce the size of a webm to 2MB?
We're talking about WebM here. Please refer to this sentence in the ffmpeg guide I linked to in my answer: "there's a constant quality mode (like in the x264 encoder) that will ensure that every frame gets the number of bits it deserves to achieve a certain quality level, rather than forcing the stream to have an average bit rate. This results in better overall quality and should be your method of choice when you encode video with libvpx. In this case, the target bitrate becomes the maximum allowed bitrate."

With CRF specified, b:v is treated as the max allowable bitrate, not the target bitrate.

comment Taking video from a DVD & Making it Editable
Well, I'd suggest the next option would have been to download ffmpeg for Mac and remux the VOBs into a MPEG PS container. There's no recompression that way and it's much quicker.

comment Taking video from a DVD & Making it Editable
VTS_01_1.VOB through VTS01_5.VOB is the video itself. It's in 5 files because the DVD spec requires the files be no larger than 1GiB. Try loading those files in Premiere.

comment FFmpeg : Error occurred while encoding audio stream from ac3 to aac
ffmpeg has to be compiled with fdk. Your build apparently isn't. Use the native encoder with a higher bitrate, so "-strict experimental -c:a aac -b:a 384k" in place of "-codec:a libvo_aacenc -b:a 128k" in your original command.

comment FFmpeg : Error occurred while encoding audio stream from ac3 to aac
Your source audio is 448kbps in 6 channels i.e. ~75kbps per channel, and your target codec is AAC (a lossy codec), so it won't be lossless. Most you can do is increase the target bitrate to something like 192k or higher from 128k. You'll, of course, lose the channel separation from 6 to 2.

Try adding -a:c 2 after -b:a 128k
