Hi,
I just have a few questions.
Basically what I would like to do is to have an "in" watchfolder and an "out" folder.
Every file I move to the "in" folder must be transcoded in order to achieve a final XDCAM 4:2:2 1080i (1920x1080) 25fps interlaced with 8 PCM unpaired tracks.
Googling around, I found FFA and I tried to setup it but nothing happens when I click "start" (I'm doing something wrong for sure).

Few questions:
1) does it work in Windows Server 2003 (Basically, Windows XP)? If not, it's not a big deal since we have newer server running Windows Server 2008 R2 as well.

2) Since I need output files to be PAL interlaced (despite the input source), is there an internal way to do this or should I do it via avisynth?

eg: (Auto-deinterlace - 'cause sources may be NTSC -, resize and then interlace)

Code: Select all

tdeint(mode=2, order=-1, field=-1, mthreshL=6, mthreshC=6, map=0, type=2, debug=false, mtnmode=1, sharp=true, cthresh=6, blockx=16, blocky=16, chroma=false, MI=64, tryWeave=true, link=1, denoise=true, slow=2, opt=4)


nnedi3_resize16(target_width=1920, target_height=1080, mixed=true, thr=1.0, elast=1.5, nns=4, qual=2, etype=0, pscrn=4, threads=0, kernel_d="lanczos", kernel_u="Spline64", f_d=1.0, f_u=2.0, sharp=300)
ConvertFPS(50)
assumeTFF()
separatefields()
selectevery(4,0,3)
weave()

3) Basically... how can I do what I wanna do in FFAStrans? I tried a simple test and failed xD

Thank you in advance and sorry if these are silly questions.

Hi FranceBB, thank you for using FFAStrans and walcome to the forum!

1.) FFAStrans is not tested on WindowsXP (and Server 2003) anymore so compatibility is not guaranteed.

2.) The XDCAM-HD node will automatically convert fps and scale to fit the output. You will have a better result if applying the "A/V Media"-decoder prior to the encoder but transcoding will be slower.

3.) You need to connect the nodes by clicking your mouse on the blue field on the right side of the node and drag to your destination node and then save your workflow. However, I can see from your screenshot that the blue output is missing from the "Folder"-monitor and the green input is missing from the "A/V Media"-decoder. Are they actually not there or is it just a graphic draw issue? I have never seen it before.... and maybe related to XP...(?)

@admin... First of all, thank you for your reply.
So... the working folder was in C, but the input and output folders were on an external network drive, so I wouldn't be surprised if XP messed up with something in the network.
I'm gonna make some tests in Win 7 and I'll let you know asap. (Of course, Windows 7 it's pretty much Win server 2008 R2, so if it's gonna work there, it will definitely work on Win server 2008 R2 as well).

Good news: everything is now set and there aren't graphic issues anymore, but transcodings don't start because FFMpeg is not compiled to run in xp (it calls some functions that are not implemented neither in the xp kernel nor in the Windows Server 2003 one).
In other words, we now know that FFAStrans actually works in XP, but one of its main dependency (FFMpeg) doesn't. (Which limit it to be nothing more than a simple UI).
In order to prove it, I replaced FFMpeg with an older version, ffmpeg-20160227-git-5156578, and it worked. ^_^
