Fix NS_E_NO_PAL_INVERSE_TELECINE (0XC00D1BA4) – PAL Inverse Telecine

30-Second Fix – Just Turn Off Inverse Telecine

This isn't really a bug – it's the software telling you, in the most cryptic way possible, that you're trying to do something that doesn't make sense. Inverse telecine (IVTC) is a process that undoes the 3:2 pulldown used to convert 24fps film to 29.97fps NTSC video. PAL video runs at 25fps and uses a different pulldown method (2:2), so there's nothing to inverse. The software just can't do it.

Had a client last month who spent two hours reinstalling codec packs because of this. All he needed to do was uncheck one box.

Look in your video editing or encoding software's filter or effect settings for anything labeled Inverse Telecine, IVTC, Force Film, or Deinterlace (Telecine). Uncheck it. Save the project. Try again. Nine times out of ten, that's it.

Common apps where this pops up:

• VirtualDub – Filter list
• Adobe Premiere – Effect Controls > Interpret Footage
• HandBrake – Video tab > Framerate > Same as source (don't force it)
• FFmpeg – Remove the -vf or -af flag that includes pullup, yadif, or fieldmatch

5-Minute Fix – Check Your Source Material

If you're dead sure you turned off inverse telecine and it's still showing the error, your source file might be flagged wrong. MPEG container files, especially from older cameras or capture cards, can have metadata that says "this is NTSC telecined" even when it's actually PAL.

1. Open the video file in MediaInfo (free tool, get it from mediaarea.net)
2. Look at the Frame rate field – if it says 29.970 fps (NTSC) on a PAL source, the container is lying to you.
3. Also check Standard – if it says NTSC on PAL content, you'll need to fix the container.

Real fix here: Remux the file into a new container. Use ffmpeg (command line) or MKVToolNix (GUI). This strips the bad metadata without re-encoding the video – takes about 2 minutes.

ffmpeg -i input.mpg -c copy -map 0 output.mkv

Then try your editor again. The error should be gone because the software no longer thinks it's NTSC.

15+ Minute Fix – Re-encode the Video Properly

This is the advanced route – only if the quick fixes failed and you're dealing with a weird hybrid format (like a PAL source that was incorrectly telecined to 29.97fps by shoddy hardware). Happens sometimes with old TV captures or DV tapes.

Step 1 – Identify the actual frame structure

Open the file in VirtualDub or AviSynth and step through frame-by-frame. If every 5th frame is a duplicate, you've got NTSC telecined content that is actually 23.976fps film. If you see a pattern of 2 identical frames then 3 identical frames (2:2 pulldown), it's PAL with 2:2 pulldown – do not apply IVTC. Just drop the duplicate frames.

Step 2 – Re-encode with proper deinterlacing (not inverse telecine)

For PAL content, you don't need IVTC. You need simple deinterlacing if the video is interlaced. Use bwdif or yadif in FFmpeg:

ffmpeg -i input.mpg -vf bwdif=1,format=yuv420p -c:v libx264 -preset medium -crf 18 output.mp4

If the source is already progressive (no interlacing lines), just re-encode it straight without any telecine or deinterlace filters:

ffmpeg -i input.mpg -c:v libx264 -preset medium -crf 18 -vf fps=25 output.mp4

Why You'll Never Really Fix This by Doing a 'Workaround'

Some people try forcing the frame rate to 29.97fps and then applying IVTC anyway. Don't. The error exists because the software knows PAL content doesn't have the 3:2 pulldown pattern. Forcing it will either crash the app, give you choppy video, or both. I've seen a user encode a 10-minute video three times before realizing the culprit was a single checkbox in his filter chain. Trust the error – it's trying to help.

Bottom line: Inverse telecine is an NTSC thing. PAL users just need deinterlacing or nothing at all. Turn it off, check your container metadata, and if all else fails, re-encode without any telecine filters. You'll have your video fixed in under 10 minutes – even if you go all the way to the advanced step.
