ElGato Video Capture to HUFFYUV on macOS?

[jucor]

Dear forum

Could anyone please help me record from ElGato Video Capture on macOS to lossless raw frames, please?

I am operating on a small budget, have an old VHS recorder without TBC and without S-VIDEO output, and bought ElGato Video Capture based on their advertisement that they are fully compatible macOS. Poor hardware setup, I know [thanks to all the great info on this forum] My idea is to try and make up for the poor hardware by capturing raw frames (compressed lossless, e.g. HUFFYUV) and post-processing using recent deep learning advances (I'm a machine learning researcher with idle hands )


Where could I find either:

• a macOS device driver for the Elgato Video Capture RCA-to-USB dongle to scan VHS, to use third-party video capture software (Shotcut, KDENLive) that supports lossless quality dump (HUFF2YUV ideally). (a man can dream...)
• or a way to trick ElGato Video Capture app (currently in 2.0.7 on macOS) to save into a lossless codec without any other post-processing, please?

If I were on Windows, I'd use VirtualDub, but I'm not :/ Is ElGato advertisement misleading, or is there actually a way to properly use their hardware on mac?

Alternatively, a pointer to any cheap RCA-to-USB dongles that are compatible with third-party capture software on macOS is also welcome

Thank you very much for any help, and happy new year!

You will probably be better off contacting admin (see link at bottom of screen) to have your topic moved to the dedicated Mac forum.

However, lossless codecs such as huffyuv are Windows only. I do not think that even Apple have a truly lossless codec.


And with the Elgato you may well be restircted to the software that comes with it and resticted to h264 video.


Beyond that, the Mac forum might assist.

You may be able to using ffmpeg command line if the device gives you access to an uncompressed stream via avfoundation:

Whether it does though I don't know
(I'm a bit unsure if the huffyuv encoder in ffmpeg produced compatible files with the standalone one huffyuv windows codec but it supports utvideo and ffv1 lossless codecs which compress better in any case, or alternatively near lossless stuff like prores if you want to be able to load it into stuff like final cut.)

Thank you very much to both of you for these suggestions! Will try both
