Does anyone else do much upscaling of recordings from the UK Freeview service? I mostly stick to encoding standard 720x576 xvid avi's at about 650-700mb per hour... but on the odd occaision I'll try scaling up a movie.
I've had a few goes and it started off a bit hit and miss, but have managed to get some good results.
The best one I've done so far was I Robot, which was broadcast on Channel 4 a couple of months ago.
My process is:
1. Get recordings onto PC using TwinRip to extract PVA files from my Pace Twin PVR.
2. Edit out adverts using Cuttermaran
3. Encode video + audio in AVI container using Avidemux at the following settings:
Xvid MPEG4
- 2-pass final size or alternatively 4600kbit or higher 1-pass CBR.
- Chroma and Interlacing modes turned on
- HQ B frames
- Level 6 motion detection
- Level 4 extended search
- MPEG & Trellis quantisation
- Filter: MPlayer resize (720x576 to 1280x720, Lanczos3)
- Filter: MPlayer hqdn3d denoise filter (default values)
- Filter: MSharpen (Strength 120 to 150)
- I dont apply any de-interlacing
Audio is almost always left as the default MPEG2 48KHz stereo format as broadcast - there seems to be little to be saved when transcoding it to MP3.
I watch all of this on a 720p LCD TV (cheap 27" Mirai model in my bedroom) via a Deuple 350 HD media player.
Here's an example of the output

BBC1, BBC2 and Channel 4 seem to be the best for getting high quality transmissions that are suitable for upscaling.
The only downside I've found is that my dual Athlon MP 2600 setup is getting a little long in the tooth to be doing this! :)
Anyone else bother upscaling any Freeview content? What are your methods?
