Hi,
I hope I can help someone!
I would like, from two relatively high-resolution videos full of the same scene (a video for the first half, one for the second half) an interlaced video to make. Freeware solutions synonymous command line tool or via the scripting language to run, I would be very accommodating. The final format will be (after additional scaling) 16:9 PAL SDTV's. If the tool or another 16:9 a "square pixel" Resolutionin HDTV (1920x1080) then the clip still synonymous PAL 16:9 SDTV scaling can (768x576), so that the clip is synonymous of each identified as 16:9 , would be particularly gratifying.
About any reference Tip and I would be very happy and thank you in advance for any friendly help!
Regards
Bongojoe

Avisynth script with the following:
[code: 1: aa0087e76c] video1 = avisource ( "video1.avi")
video2 = avisource ( "video2.avi")
interleave (video1, video2)
separatefields ()
select every (4,0,3)
weave ()
converttoyv12 () [/ code: 1: aa0087e76c]
You should resize it before Interlace. Then the whole would look like this:
[code: 1: aa0087e76c] video1 = avisource ( "video1.avi")
video2 = avisource ( "video2.avi")
interleave (video1, video2)
lanczosresize (720.576)
separatefields ()
select every (4,0,3)
weave ()
converttoyv12 () [/ code: 1: aa0087e76c]
The AVS file you can then, for example with the Cinema Craft encoder to encode MPEG2, including the 16:9 day.

SUPER!
MANY, MANY THANKS! Avisynth I fortunately already installed. So fast that I get a solution, I would not have expected. :)
Best greetings

A really nice interlaced picture for the old tube but you get only when you are with at least 50/60 fps've recorded.
To make it to the cameras internal synonymous. They process 50 or 60 HD frames per second and then half of it make what s.Ende compressed (believe it or not, 50p is far less computationally intensive than 50i:-b, but it feels so dear marketing Fritzen).

Since you're mistaken: only those lines from the sensor to adapt to the current field. For a progressive picture data should be twice the size or the transmission time for the information twice as long. The latter would be a very strong Rolling Shutter Effect lead. Also, the encoder (MPEG2 video or H.264) in the same time would have the double amount of data processing, which is certainly not readily possible.

PS: I'm a fan of progressive material with 50Hz, but currently there are officially only 720p - any other format can be found either in the broadcast is still in the BD standard.
