Video transcoding problems (Da Vinci Resolve compatibility)

esuhl

I have ZERO experience of editing videos, but thanks to some great advice on a previous thread, I installed the Da Vinci Resolve (DVR) video editor.

It's not compatible with the MOV files I have, so I used ffmpeg to convert them to MP4. The output files play perfectly in VLC, but Da Vinci sees them as silent audio-only files.

So I tried again, specifying H.264 video and AAC audio streams in the MP4 container (a common standard?) but I had the same problem.

ffmpeg -i input.mov -c:v h264 -c:a aac output.mp4

Does anyone know how I can transcode my MOV files to MP4s that are compatible with Da Vinci Resolve?

Also, I might upload the video to YouTube. Is there anything I can do to ensure compatibility with DVR and optimise Youtube quality...?

Cheers for any tips!

Are you running Windows 7? This may have been a Windows 7 thing and KB2670838 apparently resolves it (although this patch is itself six years old).

With regards to YouTube, just upload your resulting file. YouTube will sort it all out. Upload High quality and the site decides on the user plyback whether to feed it "1080 HD" or "potato vision 144p" depending on the available bandwidth.

I have no idea at all. I am only here to say that Handbreak can convert to h265 which gives higher compression and better looking films, and mp4 too. Unsure if it reads your file type though

then there is this too https://www.guidingtech.com/8848/use-vlc-player-to-convert-videos-from-one-format-to-another/

Thanks, but I'm using Arch Linux.

Ha! I never knew that! Nice! Sadly it creates a Matroska file, which DVR doesn't recognise.

I've discovered I can use ffmpeg to transcode to an mjpeg video stream (with an aac audio codec), in an AVI container, but it results in really low video quality. Nothing else works (MP4 containers, other codecs). Weird.

Maybe I can get ffmpeg to transcode a high-quality video stream somehow...?

The windows version on 10 pro has 15 different type to choose from if you press the spanner (config) button - That was at work.

My home one on 10 Home, but the latest vlc version has 23 different profiles with 15 different codec types. aac audio export is not one of the options

Well done using ffmpeg - it's a great tool, I use it for loads of differnt video jobs from transcoding, cutting and cropping, lightening dark videos and generating images.
This site has all the documentation you should need:
https://ffmpeg.org/documentation.html
It's taken me years to master it and even then I think I'm only scratching the surface.

Also see if you can install winff - this has a simple gui and creates an ffmpeg command which you can run or save and edit to run later to suit
