Some years ago I posted here about how I edit TV programmes to remove the ads and edit the subtitles. The world moves on and, as others have noted, my then favourite video editor (VideoRedo) is no more. My other favourite tool is SubtitleEdit with which dvb subtitles can be easily OCRd to produce an editable .srt subtitle. With the end of support for Windows 10 looming, I am preparing to move my last Windows PC to Linux. The other 3 migrated long since. This is a voluntary move on my part since the PC in question is quite capable of running Windows 11, but I'm not prepared to put up with Microsoft any longer. Unfortunately SubtitleEdit performs very poorly in Linux, so that's both my preferred tools gone.
These days I mainly use my hummy to record from ITV1, C4 and Channel 5, and then clean up the recordings before viewing. I need a method for doing this with Linux software only.
So far this is the best process I have come up with:
Of course, there may well be better solutions and if you've found one, please share it here.

So far this is the best process I have come up with:
- Record, decrypt and download the file to PC. I use Filezilla to download.
- Top, tail and remove the ads using Avidemux. I seem to be able to make cleaner cuts with Avidemux than in the past. Save the edited file.
- Open the saved file in MKVToolnix and deselect all streams except the audio. Remux. The result will be an .mka file.
- Use the online version of Clipchamp to generate captions from the .mka file and download the result as an .srt subtitle file. In most cases I find the results of the speech-to-text conversion to be remarkably accurate; better in fact that those given by SubtitleEdit's OCR engine. If you wish, the .srt file can be further edited using any linux-based subtitle editor - I use SubtitleComposer. And yes, I know that Clipchamp is a Microsoft product...(sigh)
- Use MKVToolnix again to mux the .srt file with the video file.
