Any hardcore encoder here could help ?

[Mayflower]

Hey

When watching my recording of the airshow I attended two weeks ago, I was tired of those horizontal lines when watching my video recorded with my Sony camcorder. I tried to deinterlace the video. But VirtualDub + Divx + deinterlace = F-a-i-l. (see below), so maybe someone here who knows about encoding could help

Overall, here's what I did:

1- I used Sony Vegas to transfer my recordings.
2- Used Vegas to do some quick editing and Rendered as .avi UNCOMPRESSED (both for video and audio). Resulting a 35Gb file for 21 minutes.
3- I installed AviSynth2.5 and used this script :
AVISource("test.avi")
separatefields

4- I opened this with VirtualDub and loaded the filter "DeinterlaceSmooth" from GunnerThalin.
5- I chose Divx 6.8.3 Codec (2 logical CPUs):
Home Theater / 3000 bitrate / Insane quality / Rest on Default
6- I chose MPEG Layer-3 48kbit/sec for audio compression
7- Save as AVI. And wait as VirtualDub try to process but nothing moves, video data stays at 0, total time stays at 0. A minute later, an error (see image at the end) pops up saying that VirtualDub has crashed.

I have this error whatever way I try to deinterlace a video along with Divx codec.
Many website recommand this filter to deinterlace and suggest to use Divx, but why I keep getting this error? Divx is the ONLY codec that provides quality and small filesize.

Thx

I'm not expert, but I just got vegas platinum a few weeks ago and have been playing around with compression alot lately.

Generally, when I use DivX, I use the unconstrained profile. (for me) Playback is always on the computer so "certification" isn't necessary. Try using the unconstrained profile to see if it makes a difference.

Try a different codec just to see if it works. My fallback codec normally is wmv. Just try it to see what happens.

I've found XviD to be have better quality than DivX at the same bitrate. But that was with one pass encoding.

I've also found H.264 to be better than both Divx and Xvid. Like super awesome better. Divx/Xvid always makes my videos have lots of artifacts, as if SD DV video wasn't already bad enough.

Just some thoughts/ideas. May or may not be helpful. :hmm:

Thx Spark, gonna check your suggestions
and yea, all codecs work except Divx. I also tried using the Xvid, it worked, but to have to same quality than Divx, the resulting filesize was like three times bigger..
I will search about the H.264 also, see if it's any good
thx for your help!

EDIT: sh!t , gotta be kidding me... I just used the Unconstrained profile in Divx and it freakin worked... bad news is that it won't be able to play on Divx certified DVD player... is there a way to make it work in other profile.. how come..

I think when you apply a profile, only certain features work to ensure the file will play on lots of players and be ultra-compatible. Have you physically tried playing the file on a Divx certified player?

I also tried using the Xvid, it worked, but to have to same quality than Divx, the resulting filesize was like three times bigger..

:hmm: I don't know what to say. I could be remembering wrong, I did my Divx vs Xvid tests long ago.... :embarassed:

not yet, will try.

doesnt matter, I think i'll just convert the avi to dvd structure before burning. that would be the safest way
