Advice on video conversion strategy for TV Shows and Movies
I have now upgraded to a Premium Membership. I am sure its well worth it, given the knowledge I have accumulated already by being a Free member for 2 years.
I need advice on video conversion strategy in two different scenarios. CASE 1: I capture a huge number of episodes of a TV Show from Satellite box using Canopus ADVC-110 in DV-AVI format (PAL). Each show usually has an expert giving lecture on a health topic. It is like a 'talking head' most of the time. No movement, with occational graphics. Duration of each show: 20 minutes. I have captured about 200 episodes so far. My goals are... 1. To preserve the original captures in a format that doesn't degrade (much) the quality further when converted to another format. That would be my master copy, instead of DV-AVI, which is simply taking too much space. (Matrox's I-Frame only MPEG-2 is a choice here? though it cannot be played via a media player) 2. To 'shrink' each episode to some format (H.264???) in order to store them on USB storage and watch using a media player, also, make them compatible with Blueray, so I can, in future, make a Blueray disc with menu for selecting each episode and play it. CASE 2: I regularly capture Black & White movies from Satellite box using Canopus ADVC-110 in DV-AVI format (PAL). After cutting out the commercials, they get converted to DVD-Video format and stored on the hard drive. I also burn each movie onto a DVD Blank so that serves as a back-up copy. Once done, I delete the original DV-AVI file. With the advent of newer compression technologies and media players, I would like your suggestion on which compression to use (H.264???) for both storing on hard drive as well as storing on blank optical media (currently I only have DVD Blanks. Might go for Blue-ray in future). I tried playing a Matrox I-Frame MPEG-2 file via my ASUS Media Player but it didn't recognize the format. Your suggestions are appreciated. Regards |

I-frame requires a higher bitrate that a typical IPB GOP (or even IP GOP) MPEG-2 encode. As such, the file size is comparable to DV. The benefit of MPEG-2 vs DV -- for NTSC only, not PAL -- is that MPEG-2 4:2:0 or MPEG-2 4:2:2 has better color quality than DV 4:1:1 on captured and converted sources. (Note that DV for "shot" video is fine -- it's converting/recording that's an issue.) So there won't be much savings here. Quote:
Though 15Mbps would be ideal, 10Mbps would be perfectly fine for talking heads. Quote:

You have a number of options, but I'll be glad to help you sort out the ideal workflow. :congrats: |
Thanks admin.

Also, is 'Master Copy' different from 'Archival copy'? Quote:

Admin is across the room from me, so I am quoting him.

It's going to be more compression maybe, its not going to be better or worse, its just a different kind of compression and it takes longer to do. I worry that in 20 years from now, some data files wont be playable anymore as compared to a DVD/Blu-ray Video disc. Some of the realmedia files and even some avi/wmv files from 10+ years ago can't be played today.

Thanks for remembering to answer this.
