Help!
Video compression ... hhheeeelllppp

Hi there,

At the time being I want to record my FPV video on my laptop.
I have the easycap usb card (and my laptop is not that strong - compaq nx5000)

Can you please post your compression, video and codecs setup ?

Tips and suggestions will be highly appreciated

Thanks
Gil

save yourself the trouble buy an old digital hi 8. they have dvi out/in.
most of the time they are around 20 bucks on the locally used web site.
ie usedvictoria.com.
this way you get the raw analog avi file. the dvi port is considered a zero loss port also.
this is the cheapest way to get the smoothest and cleanest recording onto your desktop computer at the end of the day.

You have to find VirtualDub solution. There is english translation of it on this forum. Oryginaly written by Lukisek.

videocruzer - easy to say, hard to find. Almost none on auctions in my country got av-in. Really hard to get that kind of camera.

Hi Diem,
I'm familier with VirtualDub but do you have any reccomandations for the setup ?
I must say I'm getting lost with these endless lists of codecs.
Which is a good compromize between file size and picture quality, when it comes to high motion ?

Thanks,
Gil

Very nice quality, even average laptop can handle it.

Quick and easiest....

Install xvid codec from http://www.xvid.org/

Setting up de-interlacing filter:-
video-->filters-->add-->deinterlace

Suggest File-->save processing settings so can be re-loaded at any time quickly using File-->load processing settings

Setting up XVID:-
1 Select Video--> full processing mode2
2 Select Video-->compression-->xvid MPEG-4 codec the hit configure
3 Toggle target quantisizer button to display target bitrate or quality/size you want

I tend to go for a bitrate of 10000, but depends on how long your vids are and how much you need to upload.


If you can get h.264 working that seems to be the best/most commonly accepted high end compression. I've not been able to get it to work with Virtualdub.


If your working with non avi files, might want to take a look at avidemux. Another free one that is similar. Possibly a bit easier to use, but it has the big advantage of working with several poular file types.
Donald Grafts smart de-interlacer is very good too, but for the FPV vids I don't think if you would notice much difference from the standard.

And don't forget there are some good supporte apps out there:-

Good luck!

Disk space is cheap and plenty now a days. So the master recording should have optimal quality. I would recommend using a DV codec for the original recording while flying. Better for editing also. Then you make a Xvid/h264 from the finished result for uploading.

That would be my preference too if you have the disk space. Apps seem to be geared up better to work with raw avi too.

I run my eeePC1000h with an EasyCap USB converter and capture with VirtualDub. The key is using a fact compressor. MJPEG gives virtually no noticeable video lag even while capturing at 720x576 and running fullscreen simultaneously. Also running uncompressed audio helps out a bit.

Use MJPEG codec, it put the lowest pressure on the processor, even 5%, but the files are huge, even 20M/sec, depending on the chosen quality factor. Which is good... all depends how much free space you have on the HDD and what is the write speed of the system.
