I need to downgrade 720p to standard TV resolution, how?

[JDMFanYo]

I have come back from holiday having used the GoPRO HD camera, problem is, my laptop isn't up to the job of playing back 720p so it's a little glitchy.

I've looked unsuccessfully on google, but is there software to downgrade this to standard tv format so it plays fine on pc?

thanks

You will need to transcode or convert to another format and reduce quality at the same time

15 day free trial of http://www.divx.com/en/software/divx-plus/converte... should do the trick

Handbrake will do most stuff to most other stuff

http://handbrake.fr/

It's OS independent now as well, which is nice.

Not 100% certain on which files you have at the moment, but Handbrake should be a good starting place.

ETA: Just read that the GoPRO uses the H264 codec in a MP4 wrapper, so you should be ok with Handbrake.

Try downloading CoreAV. It's a more efficient codec for playing HD and may even improve your 720p playback. What's the spec of your laptop?

Recommended Hardware Configurations for proper CoreAVC™ Playback
The CoreAVC™ H.264 Video decoder for windows directshow has the following 'recommended' hardware configurations below: Noting that the recommendations listed are measured for full screen video playback and a more powerful system will deliver the best playback experience. But because of how efficient CoreAVC is, you may find that what it takes to perform at these levels can be achieved just as well on a slower PC too.



CoreAVC™ for Windows
CPU - 800 MHz or faster Intel Pentium class or equivalent AMD processor

RAM - At least 256MB of RAM

OS - Windows 98, 2000, XP, Vista, 7

Yes. Definitely try that. Also try a different player, I'd recommend VLC Player.

Thanks all

I have downloaded the codes, though this hasn't improved things much. I find that VLC is actually more laggy than quicktime (which surprised me).

Anyway, my spec is:
Acer Aspire 5720
Windows Vista Home Premium (SP2)
Intel Core 2 duo @1.50 ghz each
2gb ram
32-bit OS

It's more for my dad who's pc is far worse than mine, he'd like a copy of the videos and pointless giving them to him if his pc won't play it smootly.

P.S. This divx plus is very good, seems to be working so far! thanks for the heads up

I'm surprised that you laptop wouldn't play 720p video.

My old IBM T43 played it no bother. My guess would be that your machine has something else going on inteh background.

Out of interest try playing the files through Zoom Player

You can get the free version from here: http://download.cnet.com/Zoom-Player-Standard/3000...

I've always found VLC a bit bothersome with MKV / H264 files whilst Zoom is much better.

I'm pretty anal when it comes to what's running, I regularly use ccleaner and have a selective start-up to ensure rubbish isn't going on in the background.

It plays pretty well, but there's most definitely a lag. Could it be my graphics card? (Not sure where to find that, device manager I guess)

GPUZ will tell you about you Graphics card.

Check your laptop isn't running in some sort of "power save" mode in the BIOS.

It's highly unlikely to be the graphics card.

It's on 'high performance' instead of power saver (selected from the battery menu)

Before you tinker with the BIOS have you tried Zoom player? I've linked to it above

I would be downloading the standalone Media Player Classic. CoreAV handles both the sound and video playback of the MKV files I watch.

Definately do not load your system with codec 'packs' as they often conflict leading to poor performance.

?yes, but it wants to install a further 10 or so applications which concerns me.. I get an error message when loading the MP4

If you are talking about the Install Centre bit

These are all the codecs etc(how the video is compressed) that the programme uses.

I've just rerun the installer, it's perfectly safe, but if you are nervous that's fair enough.

If you didn't install the other codecs that could be the reason for the error message.

Do you have details of the message you get?

also try the demo of http://www.gmabooster.com/ - it gives a 2.4x speed increase on some intel chipsets. Makes a huge difference to my netbook so that I dont have to re-encode
