convert-video cannot find a compatible video track #203

Closed huwtheb closed 6 years ago

huwtheb commented 6 years ago

I've ripped a couple of DVDs using MakeMKV, now want to convert that MKV using convert-video. When I do, I get a "no compatible video track" message.

Using mkvmerge -i, it appears the video track is MPEG-1/2. Not sure if convert-video does not like that.

Is there a way to convert this type of video track?

@huwtheb Sorry I took so long to respond. I was at lunch.

My convert-video tool is designed to convert a video file from Matroska (MKV) to MP4 format or from MP4 to Matroksa format without transcoding the video. It's mostly useful as a helper utility for my transcode-video tool if want to switch formats after transcoding, e.g. you forgot to use the --mp4 option when you invoked transcode-video.

A DVD rip, as you've discovered, always contains video in MPEG-2 format. This video format is not allowed in MP4 files. This is a restriction by the format and not by my or anyone else's tools.

The only video format allowed in MP4 files is MPEG-4. The H.264/AVC codec produces the most widely used "flavor" of MPEG-4, and it's also the default output format of HandBrake. So, you'll need to use my transcode-video tool or some other transcoding utility to convert your DVD rip into MP4 format.

Does that answer your question?

Right, got it. Thanks, Don.
