XDCAM EX 35

[Wahyu]

Dear All,
Good day to you all,

How to create XDCAM EX 35 (mov) with codec ID xdv5. I haven't been able to make it with ffmpeg.


thanks

I was looking at this document: https://pro.sony/s3/cms-static-content/ ... 512710.pdf
and it looks like XDCAM EX 35 is literally just a normal XDCAM but with 35 Mbit/s instead of 50, VBR instead of CBR, in yv12 instead of yv16 and muxed in mov instead of mxf.
Did you try this:

I have never seen any official sony document that describes the encoding details of EX35 but i guess there is a good chance that what Frank wrote just works for you.
If you then just want to set your desired vtag, you can use commandline processor instead of deliver and rewrap the encoded file to the final destination (in my case final destination is c:\temp)

Code: Select all

"%s_ffmpeg%" -i "%s_source%" -codec copy -map 0 -vtag xdv5 "c:\temp\%s_original_name%_rewrapped.mov"

but can't change the format video to 1280x720 or need ffmpeg command executor to change this?

[emcodem]

I thought EX is always 1440x1080

[Wahyu]

I thought so too, but there are HD 720 . Maybe need change in commandline

[emcodem]

Yeah well thats the bad thing when you don't have any standard paper, you just don't know whats allowed and what not
If i was you i'd probably start by extracting the commandline that's generated from the xdcamhd encoder processor from the logs and use that in a cmd processor. You know how to do that? e.g. open the full_log.json of a finished job and search for media_creation_time, thats the ffmpeg command it created. You can copy that and exchange the source file and target file, as well as insert or change parameters as you desire

Oh... you're right! EX 35 is also 720p! O_O




I don't think it's gonna be a big deal for me to add it in the current XDCAM encoder, but as always we'll discuss internally. (TL;DR I'll ask for Grandmaster's blessing xD)

I hope there is an update regarding this.

in version 1.2.2.1 I see the wrapper TS in H.264 encoder and this wrapper is missing in the next version even though I hope there is an additional MP2 audio format on the TS H.264.

I hope there is an update regarding this.

This is a start:






I committed the code to our internal branch, but I'm sure Grandmaster Steinar will polish it and improve it (after all he is called "Grandmaster" for a reason).

wrapper TS in H.264 encoder and [...] MP2 audio format on the TS H.264.

I don't think it's gonna be an issue to add 'em both, but it's easy for me to forget. If I forget, please remind me, we've all been really busy in the last period, not just me but also Ben Ben, emcodem and Grandmaster.
