Do all AVCHD cameras use the same compression format?

Do all AVCHD cameras use the same compression format? Ie. MPEG4/AVCH.264. I want to use Canon AVCHD camcorders (HF G10) recording to SDHC cards and then play those cards in a Panasonic TV that supports AVCHD playback from SDHC cards. AFAIK the folder structure on the card is the same for all cameras.

Yes, AVC is, by definition, AVC which uses H.264 MPEG4 compression. AVCHD is Long GoP (12 frames) while AVC-I is intra-frame (like DV). However, there are many flavours of AVCHD, because not all compressors use the full range of compression tools available. So, while any AVCHD-compressed data stream can be decompressed by a standard decompressor, you can't necessarily estimate the level of compression artefacts just by looking at the data rates. Some cameras come clean about this (e.g. my Panasonic DMC-TZ7 uses 'AVC-Lite', which clearly doesn't use the full kit of tools, the camera's too small and the batteries too small to do the full job).

Get my test cards document, and cards for 625, 525, 720 and 1080. Thanks to Gavin Gration for hosting them.

You will find that the folder structure for AVCHD is not always the same on different recording devices as is the recording data rate.

Do I presume correctly that you do not have the Canon camcorder?

If so I suggest that you take a card to your dealer and record some video then try it on your TV

If it's any help I have the canon HF11 and I can take the card and plug it in my western digital HD player, go thru the directory structure and play the video direct.

I haven't found an AVCHD card or camera that doesn't work with Panasonic Blu-ray recorders. I would expect their televisions to be equally capable (if not better). Panasonic cameras/files are favoured a little in that shots are shown date/day etc. Files from other manufacturers' are lumped in one clip but can be divided by chapter - sorry if that's a bitty explanation.

Mpeg 2 SD camcorder cards (and cameras via USB) are also supported by the BD recorders.

Non-AVCHD compliant cards cannot be read so that rules out cheap flip type cameras, many DSLRs and a few oddball Sanyos.

My good friend and DVdoctor member Julian Barnes (aka Lurcher) had quite a decent thread going on the subject over at AV Forums.

I don't have either camera or TV yet. I'm going to be supplying a couple of semi portable classroom/off site recording systems for a member of staff. The simplest method would be to connect with an HDMI cable and play directly off the camera for immediate playback, but I would really like to be able to keep the camera and TV separated as the recording and analysis of the recordings will most likely be done in different areas, hence the idea of using a TV with an SDHC/XC card slot. It's a tossup between the Panasonic HS or TS900 and the Canon HF G10. Cost really isn't a deciding factor but there's no point in using the Canon if the files won't play in a Panasonic TV.

I suppose the obvious solution would be to go to my local Canon supplier and record some footage to test.

If they don't play, I'll eat my hat. HF-S200 files play OK in our Panasonic decks - no reason why AVCHD capable TVs won't do same. If I'm passing a retail park later this week I'll see if they'll allow me to stick a card in - what model of TV is in consideration?

TV is a Panasonic TXL24E3B 24"LED. I also have a Western Digital Media Player which is nice to know could be used.

Haven't seen one locally but Panasonic say that model does....

Are there 1080p TVs that won't play AVCHD? Disconcerting if there are. I'm looking at LG tellies, no AVCHD camcorder as yet, but the need to plan ahead!

Hi Ron,

AFAIK we're talking about the SD card file type compatibility (AVCHD) of the telly in question.

All 1080P TVs can hopefully show all 2D flavours of 1080P video when fed via HDMI. There used to be a fuss made over 24P capability (film mode) but I think this has gone away in recent years i.e. they all do it.

Hope that helps.

Gavin
