Don't be surprise. My source file is very small because it's a test i make before i choose the definitive format for the real files.

Your capture is 16:10.

To put it in a 1080 16:9 display aspect, you will need to crop or have black borders. The slight enlargement will degrade quality some, in addition to 2nd generation encoding loss.

Your capture bitrate of 1Mbps is too low for motion video.

Thank you for providing file properties!

j-v wrote on 1/23/2020, 12:44 PM

WMV is not possible because the framesize of your source cannot be rendered with wmv.

But if you want to render it to the same type of file and the same bitrate ( and the same size of file) you have to do it this way( a lot of settings):

Thanks you both, Musicvid and j-v,
You help me to understand. I'll follow your advice and i'll tell you how it goes.
Thanks a lot.

J-V, I was able to render close enough

dominique-viollet wrote on 1/24/2020, 7:11 AM

Thanks FayFen,
i have tried this but the rate is 3.47 (rendered/original) on my system.
The j-v's method gives me 1.7, that is quite fine for me.
Thanks all for yours tips !

I would really like a feature where I could simply match the output format (not just the project settings) with the input format so that trimming parts of a single video file and rendering does not produce a larger file than the source. If the source cannot be rendered to the same, then for the 'simple' method to say why not and choose the next best - even if the file type is changed. The number of possible render options is huge, so a feature to 'render to match source file format' would save a whole bunch of these types of query.
