I've finished my first task in houdini learning a course and now I want to export the sequence images as video file. So I clicked File -> Export -> Video for windows 64bit… but somehow the result was very different from what I'd expected.
- In Mplay
- Exported video(.avi) played in a player
- Render camera option
(Sorry I don't know why but this box was appearing in Portuguese somehow. It means something like ‘without compaction’) - And these were export options for the video. (I'm using Houdini Apprentice.)
As you can see, the exported video ratio and color don't match with original Mplay video. I'd like to know how I can make it match exactly as in the Mplay video…

The aspect ratio seems OK for the render, looks like 1280*720. The color is due to the gamma value… Try setting to 1 (pre-encode options, your image No.3) could you watch your video on an other machine/device to check for the colors. Look in your OS what GAMMA it is using…
Maybe your mplay is configured to “fit image to window” or some similar. it seems squashed vertically.

It most certainly does not. The aspect ratio *not* being 16x9 is the most obvious thing about it.

Your pixel aspect ratio is not 1, is that intentional? If you want anamorphic video, I think you'll need to use better encoder such as ffmpeg to specify non-square pixels to the codec so it gets embedded in the video metadata. I don't recommend using mplay's video export for anything. Use mplay or a copnetwork to export the rendered sequence from linear light exr's to video space images, then pass the gamma space image sequence to ffmpeg on the command line.

I selected that pixel aspect ratio intentionally but without knowing what it really would do to my video. I thought it would change the screen proportion of the video without distorting pixel ratio itself somehow because this option was adjusting the opaque field in lateral sides of the viewport. (In this point that I searched plenty of what you've said, I seem to understand much better of everything) Since my monitor is ultrawide(21:9), I wanted for the video to be 21:9 too and now I think I should've just changed the resolution. But I still don't know why the color is weird. I'll try to figure out why trying other ways. Thank you for help.

I tried it already but no change… as you said, I'm gonna try other options around. Thanks for help.
