Convert MOV Video File Encoded as `qtrle` in Windows Using FFMPEG

I downloaded the latest FFMPEG for Windows (Version 3.2.4).

I wanted to use it for converting a MOV File which contains qtrle uncompressed video.

The video can be downloaded on this link - https://www.sendspace.com/file/qjjkhj.

I can view the video in VLC Media Player yet when I try convert it in VLC into any video format the output is invalid video file.

I also tried using FFMPEG using the following command - ffmpeg -i DL126H.mov -c:v copy VideoClip0002.mp4. Yet the result was: [mp4 @ 00000000026744e0] Could not find tag for codecqtrlein stream #0, codec not currently supported in container Could not write header for output file #0 (incorrect codec parameters ?): Invalid argumentStream mapping:.

I also tried the following - ffmpeg -i DL126H.mov -c:v mpeg2video -b 16M out.mpg yet the output, just like in the case of VLC was invalid video file.

So I'd like the assistance with:

1. Convert into Windows friendly format (With High Quality)?


2. Change container into format working in Windows (With no rencoding).


3. Convert into valid MPEG2 (.mpg) with high bit rate.

Thank You.

Answer

The syntax is simply

ffmpeg -i DL126H.mov -pix_fmt yuv420p VideoClip0002.mp4

This will encode using default parameters i.e. using libx264 at CRF 23 and AAC at 128 kbps.

To use custom parameters, like better video quality, use

ffmpeg -i DL126H.mov -crf 18 -pix_fmt yuv420p VideoClip0002.mp4

This will preserve more of the source quality but a larger file

In FFmpeg's case, the 'release' build is never the latest version. Always go for the nightly/snapshot/git build.

If you want to encode to MPEG-2, use

ffmpeg -i DL126H.mov -c:v mpeg2video -b:v 16M -bufsize 30M -maxrate 30M -pix_fmt yuv420p VideoClip0002.mp4

The MPEG-2 spec was designed during SD video days and its defaults are not suitable for HD video. So a couple of them have to be manually overridden. The result plays for me in WMP12.
