Thanks for convert menus but I would like to ask about it. When a file from the Galaxy was added, it requires converting to CBR. It is okay.
I convert lossless but it works without my nVIDIA. Only lossy format is available with nVIDIA. Is there any other good way to let my nVIDIA to join lossless converting?
Or I would like to convert externally such as FFMPEG. Can I get any parameters can be? I tried some of parameters found online but KDEnlive still wants to convert its own format.
Hi! I suspect you might be confusing a few concepts here …
Nothing should require conversion to Constant Bit Rate. There are very few use cases where some form of Variable Bit Rate is not preferable now.
So I assume you are talking about the conversion from variable frame rate that is required for sane editing in current versions.

What lossless format are you trying to use? Kdenlive supports FFV1 (and a few other less desirable formats) for truly lossless transcoding - but they are mostly interesting for archival purposes, they aren’t often used as an intermediate format for editing, because the size of the files you need to deal with balloons immensely.
When people talk about ‘lossless’ intermediates, what they usually mean is ‘perceptually lossless’ for a limited number of transcoding cycles. And the options Kdenlive gives you for transcoding VFR video generally fall into that category and are entirely sufficient in almost every case.

Again, these two things are somewhat at odds with each other. Hardware based encoding is usually a compromise which aims for reasonable quality and compression at the highest possible speed.
If what you want is the highest quality and greatest compression for a truly lossless archive copy, then the best software encoders will almost always do a better job than the hardware ones, and spend a lot longer trying to optimally compress the content.
So the Right Answer to your question really depends entirely on what specifically you are trying to do.
