awesome, and you've only been using it for a moment; imagine how convenient it will feel when you've gotten used to it after a while :). Rock on!

I'm sure that it won't be a mad forest of features soon.-)

I just used VLC to convert the file to another MP4 file and it came in at a little over one-third the size.

MystiQ works pretty well to shrink video files for me, especially with one of the h.265 presets. Maybe you already used h.265 in VLC, though. I think with MX 25, its AV1 preset will be working with a newer ffmpeg, and that'll be even smaller.

A frontend for ffmpeg. I'm installing MystiQ now. Oh boy. Yet another app to learn at a shallow level. The file in Kdenlive says it's h.264. It looks like I used h.264 for the first conversion in VLC. Now I'm running one with 265 to see the difference.

It cut the size about in half again, but there's a glitch at the bottom of the video and there's no audio. Maybe I'll stick with h.264.

Trying to compress mp4's is where I find trouble starts for me. I usually try one of the KDenlive render choices for youtube or another web selection... but compression = loss at some point.

I've seen that option. I think I'll give it a try. That was in VLC, I think. Okay, YouTube HD makes it over three times a big again. VLC YouTube SD changes the aspect ratio and increases the size by 50%. I'll try the Kdenlive web choices. Webm VP8, it says. Slow. I don't see a choice labeled YouTube. It gets enormous. Now to try MystQ, which looks really simple. Converting for Optimized for YouTube. It's quick and pretty close in size. I think I'll use MystQ in place of VLC for the conversion.

Thanks, guys. I'm having fun.

Oh, use the newer mystiq in the MX 23 test repo. Sunrat here made some suggestions for the h.265 presets for mkv files, which I had to add in the source before the build--its great weakness is that the user can't load custom presets, only edit existing ones manually. The h.265 preset works great to shrink h.264 movies without loss of quality, but takes a lot of CPU cycles. Hmmm, I need to rebuild mystiq for MX 25 repos.

MystiQ updated.
