The main problem is that FFmpeg thinks program specifications are malformed.

[out#0/mpegts @ 0x1334c1440] Error parsing program specification title=001:st=v:0:st=a:0?
Error opening output file TRANSPONDER5A12828402-SDTV-ldish.ts.
Error opening output files: Invalid argument



I think the error is really absurd because of the following reasons
1) I had run a similar command like this however with four videos, and it worked.
2) Videos #1 (0) and #8 (7), mentioned in the command above, have no audio, however, I think, the command is so engineered it must clear any confusion caused by assuming audio streams are removed from the list because they are absent, which will break its structural functionality, or something…
Likewise, I’ll send you herein the input videos I’m using for such conversion.

Could you help me clarify this issue, please, and propose some workarounds that help solve, or at least neutralize the problem? I’ll thank your answer.
Greetings,
Cedric

I've just started working with some basic Panasonic MII capturing and note when I deinterlace the following with QTGMC via hybrid with some cropping and scaling, it introduces what appears to be a vertical one-line jitter on every other frame that I can't really see in the pre-de-interlaced footage - please see both attachments.

Any ideas how to get rid of that jitter or what caused it in the first place?

As far as the capture chain, it's an AU-65P machine (with internal TBC that can't be disabled) and output via component (at MII levels which is not standard component) which then gets transcoded to betacam digital component levels via a DPS470 is set to minimum delay transcoder mode (and does not act as a TBC).

Since the still-interlaced footage doesn't appear to have that jitter, I don't think the chain is necessarily the issue?

Thanks in advance!

https://files.videohelp.com/u/61125/goba2026.MOV
The video plays fine on VLC on two different computers and also plays fine on MPC-HC.
However the video plays upside down (inverted) on Walmart dvr. (Important clue: the video thumbnail on computer is also upside down, see screenshot.) I tried converting video to mp4 with Tubedigger convert tool, but video and thumbnail still upside down. (Additional info- Video also plays upside down on this computer Windows Media Player, which I rarely use that software, about 15 years old)
My question, how can I get the video to play correctly on Walmart dvr? I don't want to invert (recode) the video because then it would be upside down on computer.
