In terms of workflows I abandoned analogue as soon as I could. I don’t go for this fuzzy-wuzzy nonsense that analogue is better/warmer/more emotional etc. I hate ghosting, I hate tape dropouts, I hate the crappy resolution of VHS tapes and all their imperfections.
I bought my first digital TV set-top box in 2003 (HD capable too) and it cost me a fortune. That got rid of the crappy analogue TV reception part, but I still had to rely on an analogue VCR to record it. I dumped that in 2006 when digital TV tuner cards that record the raw digital TV stream direct to computer hard disk became affordable. No intervening DVD or other transcoding - the pure raw digital signal - 100% bit-for-bit copy of what was broadcast with zero degradation.
I have never looked back. I don’t miss analogue one tiny bit. I back up my hard drives every week with two redundant copies.
Half the digital channels in the UK are now on a par with low res YouTube.
The HD channels are at least decent quality, but I don't call this situation progress.
On a limited bandwidth quantity over quality now seems to be the name of the game.
But when I compare my recordings of TOTP from BBC Four SD and HD, the HD ones look significantly better than the SD ones, even though the source footage itself is of course SD.
Just to add, I thought both SD & HD broadcasts were interlaced in OZ, is that not the case?
That's what I thought, but in an earlier post Clip Magnet says this:
"The HD channel (MPEG-4) is broadcast as progressive video not interlaced, whereas the SD channel (MPEG-2) is broadcast interlaced. So if the original material is interlaced (most old video material is) then the HD channel de-interlaces it before broadcast. This can result in what looks like blurrier motion and fuzzier stills, and actually removes some of the original motion information in the original material. I don’t like the resultant effect."
Those of you recording ABC HD, have Rage in particular introduced any subcoding into their broadcast? I record retro in one block, then edit later, but I’m finding and only recently that when I skip ahead, every one of these happens at the end of every video clip or similar. Say hitscene is 26 minutes, and there’s a clip before it and after it, i can cue to the end of the clip, then the end of hitscene and so on. Didn’t seem to happen until only recently so I’m wondering if the ABC transmission is now also transmitting the end markers of items from their automation system.
SD Vs HD, depends on your perspective and what you're doing with the video. SD is fine if you are making DVDs, because the SD stream is MPEG, there will be little, if any re-encoding if you are going from PVR (like a Topfield recorder) to PC to DVD. However, ABC has greatly reduced the SD bitrate over the years, I have digital recordings in SD from ten years ago that look great but these days, they just look :hankey:, as more people have HD sets, the quality of the SD feed has deteriorated.
Original broadcasts of Countdown might not have originally shot in HD, but ABCHD is broadcast in MPEG4, a newer format. It should look better, you may even find part of the transferring process at the ABC is upscaling the content digitally before it's aired on Rage.
Another argument supporting HD is if you are uploading to YouTube, YouTube gives a higher bitrate allowance to HD videos, so again, they should look much better on YouTube than uploading an SD quality MPEG2 video.
One area where SD wins against HD is DVD creation. If you are making a DVD from the HD video, you're going from about a 50 frames per second to 25 fps, so when you look at movement in your end product, it will look fuzzy, not to mention with a HD video you're scaling down the video. So SD wins if you're making DVDs.
ABC SD & HD are both 50i so it makes no difference to that aspect of DVD creation
If that's true, then you're going to lose quality creating DVDs from SD broadcasts, I haven't recorded SD for a long time, I just looked at an SD recording from 2014 and that was 25f/s.
50i is 25 full frames/sec, interlaced.
It's what analogue tv was, and it's what a lot of digital tv still is.
