I have a work flow that can accept a file in any size/FPS and interlacing and performs multiple tests to determine the best way to treat that file so that it conforms to XDCAM 1440x1080 4:3par 25fps TFF.

I perform checks to see if the size is correct, I've written a custom AVI synth filter which takes DAR into account and adds matting and converts to 1440x1080 dar 16:9

I then check for bff interlace and perform field swapping. I check if it's already 25fps otherwise I convert it to 50p and then decimate down to 25 TFF before handing it off to the XDCAM encoder.

I just read that the XDCAM encoder will perform correct scaling (not sure about FPS conversion) so do I need all of this complicated workflow?

Is there a list of the input formats that the XDCAM encoder supports and how it treats them to conform the format?

Thanks

Hi Mark,

Most inbuilt encoders (except "Custom FFmpeg" and "Uncompressed") has pretty sophisticated mechanism for treating the input fairly. It will check interlacing and do proper scaling accordingly, conform fps, convert colorspace and treat aspects properly. So unless you need specific filters I would recomend you to try without any logic and just see what happens.
