Yes, but there are different methods of de-interlacing. My preferred method is to convert each pure interlaced field into a progressive frame. Which as a consequence, doubles the original frame rate. Meaning an 'interlaced' 25.000 fps source becomes 'progressive' 50.000 fps encode.

There was a time when media players struggled to play 50.000 fps and 60.000 fps video but happily those days have gone

Cheers

Thanks,

Ok I agree with the option to keep all frames but I want to be compatible with all players, like TV player, even to DVD format if I want to convert them some time in dvd discs. So I prefer to keep the original fps because I will delete the original tapes or they will be destroyed some time.

So what my needs : I need the best quality that keeps the original characteristics of the original tape and to be compatible to the most players.

The only changes I do, is deInterlacing and soft denoise (using handbreak).

I suggest you set your player 'compatibility' sights a little higher. As A/V manufacturers are dropping the production of dedicated DVD players, fast. The Blu-ray specification offers you more video encoding options

I suggest you keep your original tapes for as long as you possibly can.

Well, if you're serious about having your encodes compatible for use with DVD players (in accordance with the DVD spec.) your hands are tied. You're going to have to use MPEG-2 (in VOB) - that's it!

Along with the original tapes, which will degrade with time, it'd be a good idea to keep the originals on a hard drive; 4 terabyte drives are barely over $100 now. That way you always have a backup around in case anything happens to one or the other. After all, you don't need to do any deinterlacing at all to get XM1 content on a DVD! (Unless you want to apply post-production effects to it.) You can just encode and author.

As time goes on and more advanced deinterlacing gets faster on new CPUs, it's very handy to be able to go back to the originals for a remaster, as well. Make sure to backup any post-production projects, as well, to save some time.

Yes.... you have absolutely right !!!! In the past years I deleted files cos I needed the HD space. Now I am so regret it !!!.

Also note that DV can have a lot of padding bits, and PCM audio. You can shrink the size down some with your favorite lossless encoder (which should be 7z LZMA2, natch).

Yes its a thought, but it still needs a lot of space .....
Anyway, I will keep my original tapes. You never know !

From what I remember, data-wise it's around 12-13GB an hour when uncompressed. So over 70 hours can be stored on a 1TB HDD. Which is not that bad

You remember damn well. Its about 13GB / hour.

And.... an 1TB HD space its relatively cheap

I've just remembered another reason why it's a good idea to back-up your DV+PCM.avi camcorder files to HDD's...

Some hardware players fitted with Sigma Designs A/V decoding chip-sets and many Android based media players can actually play DV+PCM.avi files

But the biggest reason is that rust glued to a flexible strip of mylar doesn't have a great shelf life in typical home environments.

Digital information saved onto an analogue medium.... It's a match made in 'digital' heaven.... Where do I sign my pre-nup?
