Best Lossless Format for Intermediate Files (Vegas Pro 18)

Unfortunately hevc lossless does not seem to be implemented in Voukoder even though it is implemented perfectly in ffmpeg with a transcode script such as this:

ffmpeg -i "INFILE.MOV" -c:v libx265 -x265-params lossless=1 "OUTFILE.MOV"

x264 cannot actually achieve lossless. It's lossless setting is close but ProRes422 is generally a little better quality, faster rendering, and smaller. MagicYUV is another possible option.

If you need a mathematical lossless intermediate codec check out MagicYUV.

MYUV (MagicYUV) is just a space waster format and you should buy it if you really want to use it. (the dev force you to buy it, because free version is really useless comparing to options that full version offer!)

Hi There,

I'm looking at cleaning up some noisy VFR dark video I have for a project, prior to working on my composition. Using Neat DeNoise, standard contrast and sharpening on each individual source file which is VFR from phones. Media info below. But I'm wondering what the best option is for a lossless intermediate format so I don't lose any quality before editing within my larger composition project. I know ProRes is a favorite but rendering is Soooo slow. Wondering if I did a lossless H264 or any other format, it might work just as well and render faster.

Thanks - I'm new to Voukoder, any recommendations welcome.

Scott

Not many options left, use: MKV (FFV1/FLAC or PCM)

For your video it's 420 BT.709

I've created a pull request to submit the parameters, it just needs some time to be tested and updated to next/later release. Currently you need to go to Option tab, and find, apply the settings yourself
