AVCHD output strategy

so basically i want to build a strategy on output formats from my AVCHD HF100 camcorder and iam pretty confused in some areas so

1. My goal is to find good file format with quality comparable to my 17Mbps AVCHD which i would like to use in two ways ... as a full quality backup, and as pre-render with applied post-processes for distributing my video to other small formats ... so i was thinking if this can be h264 bluray or mpeg2 bluray ... but donnt now if this isnt too much quality in compare of AVCHD and waste of data-space (its huge :/) and also if its good format for reencoding

2. another question is wheter render my full quality backups in interlaced format or not ... i now that on classic TV when i play progressive video, it stutters ... but what about LCD TVs ? i really dont care that much about present, i think for future, sometimes i will have LCD, but isnt interlaced video even on LCD televisions more fluid, i still think that interlaced video has more information in it .. but isnt progressive better for LCD TV?

as a distribution format i use h264 mp4 ... i used wmv ... but i had problems with shifted audio, and somewhat shifted pixel lines inside me video so i think that mp4 is ok


so simply what are best output formats in comparable quality with 17 Mbps AVCHD (so somewhat full quality backups), also suitable for another encoding to other small formats
 
If you have an h.264 encoder that is capable of more advanced settings like Main Concept h.264 encoder, I've been exporting high profile h.264 files at 17mbps VBR with a peak of 50mbps for masters to encode from later.

AVCHD just like H.264 High profile can be enough as that is a 4:2:0 medium. (All internet compressed, DVD, and Blu-Ray video is 4:2:0)

thank you, you helped


i downloaded MainConcept Reference demo and looked at settings .. found there h264 presets (1080i) and duplicated it to my adobe media encoder ... now it looks pretty much the same as original, iam just going to test it and compare results and finally i would have my backup solution :) thx again
 
Man, I've got an HF200 that I'm using at 24mpbs and I think my problem goes even deeper than yours.

My computer is a total pile of crap. Pentium 4, single core, blah. Hence any footage that I bring in from this camera is completely destroyed. Just random spurts of fixed images.

What I'm considering is picking up a DVD recorder with HDMI input and taking the footage off the HF200 using its mini HDMI port and recording the footage straight to DVD. Then I could take the DVD, put it into my crappy computer's DVD-ROM, and then take the nice images off of the DVD and use those.

It's kind of round-about, and I know I'll end up with 720p opposed to 1080, but wouldn't this still be the best option considering the equipment I have to work with?

The only other idea would be to find a local place that can transfer my footage to a DVD at like 10 bucks a pop.

Whaddya think?
 
Ouch...

What software are you trying to convert the AVCHD with? It would seem to be that Premiere or Vegas would be able to create a new file for you, but it would just take forever on each file.

Yeah, except that my processor isn't strong enough to accept the data in the first place. So it's not like my computer receives all the data uncorrupted and then I just have to change formats -- the computer literally cannot take what the camera is giving it.

Huge bummer, but like I said, most of this will be for YouTube, etc. 480i will do.
 
Your computer can't play the footage in real-time, but it can transcode it just fine (will take a whale of a long time though).
 
For full quality backup just backup original files, whether to external HDD or DVD or BD, your choice.

For high-def distribution I would author an AVCHD disc and play it in a BD player.
