Hello Everyone,

I need to convert .mp4 files to .Mov ProRes, but the ProRes AW/KS encoder doesn't have an option for the wrapper so I guess it only converts to AVI ProRes, anyway i always get the error: "AVISource: couldn't locate a decompressor for fourcc", and I already tried to install lots of codecs, but it doesn't finish.

Does anyone here knows a better way to encode a mp4 into a MOV ProRes file?

Thanks

Hey zkazzay,

I feel a little stupid because i don't find a prores encoder node in my latest copy of ffastrans. However,you could use a custom ffmpeg node with encoding settings like that:

-c:v prores_ks -pix_fmt yuv422p10le -profile:v 0

I have a node that is ProRes AW/KS, and I'm using version: 0.9.4.0.

I tried that but i keep having the same error:


I already installed Quicktime, Xvid, Media Player codec pack, ffdshow and nothing.

Any thoughts?

Hmm..... as far as I know FourCC is a four-digit identifier for determing what kind of e.g. Color-Space a vide-file has inside. (Wikipedia: A FourCC (literally, four-character code) is a sequence of four bytes used to uniquely identify data formats. [...]).
can you playback the file in VLC-player? If so - can you have a look in the media-properties-window to clarify which videocodec is inside?

Looks like all your attempts of transcoding went bad.

Also, I don´t have an ProRes AW/KS-Node either, can you load up the workflow maybe?

Hello,

I have the pro res node and if I tried to encode a mp4 to pro res 422: It works well and I have a MOV container as output file.
zkazzay , your workflow is simple? like that :
Monitor folder>pro res encoder>Delivery

Thanks

Hi Benjamin,

Thanks again for reaching out.

My workflow is kind of simple, at least it works with other workflows, and the error only happens on the last phase.

Now it's given a different error: System exception - Access Violation.

here's my workflow:


also here's my ProRes Node:

Hi,
Can you try first without any decoder please? I saw you have many filters so remove them and try if the encoder works.
Thanks

Hi,

Success!!
Thank you, now i just have to find a way to do all the filters and then encode to mov.

Hey zkazzay,

i just had a look and found out that it can only be the videolayer node that causes your problems. It currently only supports avi files on input. Furthermore, the avi file you provide should have a pretty simple codec like DV or so.
If you need further help, you'd need to give us some details about what you have for the video layer, possibly you can simply encode it to DV before feeding into the videolayer node...

Hi zkazzay,

When using video on the "Insert media" and/or "Video overlay", the AviSynth function AviSource is used to read the media files. If you use a codec in an Avi-file that is not supported by AviSynth, it will fail. And this is probably the reason for the errors. Further more, the "ProRes AW/KS" was prematurely released. Simply put: it was enabled in the release by accident. So don't expect it to behave properly. The actual release will be in the next major upgrade.
